MS SQL Server :: Finding Duplicate Entries In A &"smart&" Way

Duplicate Entries
I have an application that allows the user to enter data into a table. There are multiple users so I put in some code that, I thought, would keep 2 users from creating a new record at the same time. The IDs for the records are identical and this is causing a problem.

The IDs are in the format of ####-mmyy. at the start of each month the #### part goes back to 1.

We tried a test today where we had 2 users click on the New button at exactly the same time. The IDs that were created were identical. Is there anyway on the database that I can prevent this from happening?

Here is how I create the new record id:

I get the MAX(ID) from the table
I add 1 to the ID and then insert a new record with the new ID into the table.

Any help is appreciated.

Thanks,
enak

Duplicate Entries
I'm extracting data from a log (log_history) of patients where nurses perform various actions on a call, such as assessing and reassessing, despatching etc. This is the script:

Select
L.URN,
LH.THE_TIMESTAMP,
LH.ACTION_TYPE,
LH.ACTION_BY,
LH.ACTION_REQD,
LH.NOTE,
em.position_type_ref
From
LOG L
Join Log_history LH on (L.URN = LH.LOG_URN)
left outer join employee em on (em.code = LH.action_by)
Where
(L.Taken_at >= :DateFrom and L.Taken_at <= :DateTo) and (LH.ACTION_TYPE = 'D') and (em.position_type_ref ='NU')

Order By
L.URN ASC, LH.THE_TIMESTAMP DESC

The result I get shows duplicate 'timestamp' entries and I only want to return unique timestamp entries. Does anyone have any ideas. I'm self taught and have hit a wall

Remove Duplicate Entries

I am a newb at ms sql and was hoping someone could help me
eliminate duplicate PRODUCT.PRODUCT from this statement. I have tried using DISTINCT with the same results.The ProductImage table is causing this because
the duplicates are from the PRODUCT.PRODUCT that have more than 1 image.

If anyone could rewrite this statement so I can learn from this, it would
be most appreciated!

Thank you for your time

<asp:SqlDataSource ID="SqlDataSource3" runat="server"ConnectionString="<%$ ConnectionStrings:LocalSqlServer %>"SelectCommand="SELECT Product.Product.productid,Product.Product.catid,Product.Product.name,Product.Product.smalltext,Product.Product.longtext,Product.Product.price,Product.ProductSpecial.saleprice, Product.ProductSpecial.feature,Product.ProductImage.imgId, Product.ProductImage.imgUrlFROM Product.ProductINNER JOIN Product.ProductSpecialON Product.ProductSpecial.productid = Product.Product.productidINNER JOIN Product.ProductImageON Product.Product.imgid = Product.ProductImage.imgId"></asp:SqlDataSource>

Dont Sum Duplicate Entries

Hi.
I have a table with Login and Logoff Time of users, but there could be duplicate Logtimes in the dataset, but for
different products. Because of this I cant do a distinct in the dataset. I need the Product and some other details in my Report.

I tried to make two datasets. One for the Select distinct and one for the other.

But the Problem is:
in my report, I need a table, where I make the Sum of the Logintime a day and in another column I calculate with data from the other dataset.(Logtime + data from dataset2). But this doesnt work, so I think, that is it not possible to join 2 dataset in one table.

datetime Login | datetime Logout | Product
11.12.2007 10:15 | 11.12.2007 12:15 | p1
11.12.2007 10:15 | 11.12.2007 12:15 | p2
11.12.2007 12:19 | 11.12.2007 15:15 | p2

Is there another option I can do this?

Preventing Duplicate Database Entries
Hi all.. I've been scouring the forums for about 6 hours to no
avail. This is a really simple question. I'm trying to have
a registration page that lets the user input name, email, desired
username, and password. I want to check the username and email
fields to make sure ppl cannot sign up twice. So from what I've
gathered I have a couple of options:

1) i can set up a unique constraint on the database columns,
2) i can run a select statement before inserting,
3) i can store the whole database column in a variable then search through it.

My question is how to do option 2? All of my transactions are through a sqldatasource object in c#.

Prevent Duplicate Entries In A Table
I have an ASP.Net Web appplication with a Back-End SQL DB. There are 3 Tables; Users, Groups, and GroupMember.

The GroupMember table is used to link Users to Groups and consists of just two fields; userID and GroupID.

Here is a sample of some data:

User1 Group1
User1 Group2
User2 Group2
User3 Group1
User3 Group3

Users can belong to multiple Groups. However, you shouldn't be able to have the same user and group comobination more than once. for example:

User1 Group1
User2 Group2
User1 Group1

I can stop this kind of duplicate data entry by doing a lookup first (using asp.net) to see if the entry already exists but this seems cumbersome.

Is there a simpler way to prevent duplicate entries in a table using sql?

Thanks a lot,

Chris

How Can I Remove Duplicate Entries In A Sql Query?
I have a database being populated by hits to a program on a server.The problem is each client connection may require a few hits in a 1-2second time frame. This is resulting in multiple database entries -all exactly the same, except the event_id field, which isauto-numbered.I need a way to query the record w/out duplicates. That is, anyrecords exactly the same except event_id should only return one record.Is this possible??Thank you,Barry

Duplicate Backup Entries Using SQLMAINT
I would appreciate someone pointing me in the right direction to resolve a backup anomaly
were currently experiencing. We recently installed SQL Server 6.5 and noticed that although
our scheduled tasks were running as requested the DelBkUps parameter wasn`t working. In
addition we noticed that the backup files that were created didn`t have the time portion
appended to date (suffix of backup name). The steps we took to resolve this was to install
Service Pack 3. After the install the following was observed: 1) DelBkUps parameter started to
work 2) duplicate backup entries were created, the only difference being that for one of
the entries the time portion was still missing (ie. apps_db_dump.19980722 instead
of apps_db_dump.199807221840). Letting in cycle through for a week didn`t have any affect.
The final observation is that for scheduled tasks that occur more than once/day (i.e. transaction
dump every 8 hours) no duplicate backup entries are created and file suffix is correct
(i.e apps_db_dump.199807221840).

Removing Duplicate Entries In SQL Field
Hi All,

Below is a snippet of MS SQL inside some VB that retieves
Commodity info such as product names and related information and returns the results in an ASP Page. My problem is that with certain searches, elements returned in the synonym field repeat. For instance, on a correct search I get green, red, blue, and yellow which is correct. On another similar search with different commodity say for material, I get Plastic, Glass,Sand - Plastic, Glass,Sand - Plastic, Glass, Sand. I want to remove the repeating elements returned in this field. IOW, I just need one set of Plastic, Glass and Sand. I hope this makes sense.

Below is the SQL and the results from the returned page.

PS I tried to use distinct but with no luck I want just one of each in the example below.

Thanks in Advance!

Check For Duplicate Entries In One Field
Obviously, I'm a complete n00b at SQL.

I'm trying to make the first field my primary key, so I need to fix these duplicate entry.

I could export to Excel and fix the problem that way, but in the interest of learning SQL I want to figure out how to do it properly.

Best Method Of Checking For Duplicate Entries In SQL Server
Here is my situation. I have a table in my application that pairs users with cars they like. We'll call this table Favorites. A user can browse the site and they can designate as many cars they want as favorites. For example, a user can go to the Honda Accord page and add that as a favorite car and then go to the Toyota Camry page and add that as a favorite car. However, if he/she goes to that Honda Accord page and tries to click the "Add to Favorites" button again, at the present state of my application, it will just add another entry into the Favorites table with a duplicate pairing. So, if I were to datalist the table to generate a listing of all favorites belonging to a certain user, he/she may potentially be returned with superfluous duplicate entries. Not to mention, taking up valuable database space and not looking very professional.
In my Favorites table, the 3 fields are.....favoriteId (set as primary key)userIdcarId
I've been thinking about this for awhile and I've come up with 2 solutions. I'm a newbie to ASP.NET/programming so I don't have enough insight to make a decision or to even think up of other alternatives.
1) Check proactively by doing a.....SELECT favoriteID FROM Favorites WHERE userId = x and carId = y (where x and y are variables)If I get a null return, it means I can go ahead and let the user add the car as a favorite in the database. If I get a valid value, then it means there already exists the same pairing, so I exit out without updating the table.
2) Check reactively by forcing an exception whenever a user tries to enter a duplicate pairing. I'm not sure how to do this, but perhaps, instead of making "favoriteId" a primary key, perhaps, I can make a primary key pairing of "userId" and "carId". And by trying to do an insert with a primary key that already exists, we know it won't work since primary keys by definition are unique.
Now, I expect some concurrent users on my site, so I must take into consideration pros and cons of each and determine which is more efficient. Checking proactively will force a check even if the table does not contain a duplicate pairing of user and car. However, having a duplicate primary key may be more expensive from a database point of view and may slow down lookups, etc. Or maybe neither has significant benefits, in which case, I rather go with proactive, since I've already coded it and it works fine. Or maybe there is a third alternative, which I did not think. Which method do programmers usually take and which is a better practice?
TIA for your help.

Need SQL For Finding Gaps Comparing Two Sets Of Pe
Hi all,

I have two tables - Planning and Appointments:

Planning - contains a list of planned items. Used to define boundaries for a work day and defines based on type what can be done for each item.

Id,
TypeId - the type of the planned items
BeginTime DateTime - begin date and time of the planned item
EndTime DateTime - end date and time for the planned item

In the Planning table we can have as many records per day as we need:

1, First Meeting, 1 Jan 2008 09:00, 1 Jan 2008 11:00
2, First Meeting, 1 Jan 2008 11:00, 1 Jan 2008 12:00
3, First Meeting, 1 Jan 2008 13:00, 1 Jan 2008 15:00
4, First Meeting, 1 Jan 2008 15:00, 1 Jan 2008 18:00

Appointments - contanis a list with appointments

Id,

4, 1 Jan 2008 14:00, 1 Jan 2008 15:30

What is needed?

What I need is to a find a way to compare the planned items with the appointments and to return all the periods for which a planned time exists:

Free planned time:

1, 1 Jan 2008 09:30, 1 Jan 2008 10:00
2, 1 Jan 2008 11:30, 1 Jan 2008 12:00
3, 1 Jan 2008 13:00, 1 Jan 2008 14:00
4, 1 Jan 2008 15:30, 1 Jan 2008 18:00

So, having two multitudes of periods,where the one specifies the planning templates and the other real used time, I need to find all the periods which can be used for another appointments.

I've tried several aproaches, but I always faced performance problems.

Thanks in advance.

Writting Trigger Or Procedure To Delete Duplicate Entries In A Table?
I am using Sql Server 2000.
I have a customer table with fields - CustId, Name, Address, City, StdCode, Phone.
I used to insert entries in this table from an excel file.
One excel file will contain thousands of customer.
In this table combination of StdCode and Phone should not be repeated.
If I do it in my VB.Net coding.then application gets drastically slow.
So I want to write a procedure or trigger for this.
Here what I will do, I will send all records into database then this trigger or procedure will check for
any existing entry of combination of StdCode and phone. If entry exists then this will delete new entry
or will not allow this new entry.
Is this possible to do using Trigger or stored procedure?

Finding Duplicate Records
Hello,

I searched for all the posts which covered my question - but none were close enough to answer what i'm trying to do. Basically, the scenario is thus;

Table1 contains values for UserID, Account code, and Date.

My query (below) is trying to find all the accounts assigned to a particular user ID, but also those duplicate account codes which belong to a second user ID. The date column would be appended to the result set.

The query I'm using is as follows;

select acccountcode, userid, date from dbo.table1
where exists (select accountcode from dbo.table1 where accountcode = table1.accountcode
group by accountcode
having count(*) > 1)
and userid = 'x-x-x'
order by accountcode

What I think this produces is a list of all files where a duplicate exists, but of course it leaves out the 2nd UserID...which is crucial.

Hopefully this makes sense. Any insight my fellow DBA's can share would be greatly appreciated!

Thanks,
D.

select parent_column_id as 'child Column',object_name(constraint_object_id)as 'FK Name',object_name(parent_object_id) as 'parent table',name,object_name(referenced_object_id)as 'referenced table',referenced_column_id
from sys.foreign_key_columns inner join sys.columns on (parent_column_id = column_id and parent_object_id=object_id)
Order by object_name(parent_object_id) asc

Finding A Duplicate Transaction Number
I have a problem with a 3rd party piece of software. Doesn't matter which, really. The problem lies
in a table called payments, with a column called txnumber...the newest version of this software fails
a check during installation with the message "duplicate txnumber in payment table." Not sure how
this could have happened, since there is no way to manually assign the txnumber, but the point is
not important. What I'd like to do is figure out a sql script that will return only the duplicate number(s)
so that I can either remove or change them manually. Unfortunately, I'm not terribly familiar with sql.

Any suggestions?

Finding Primary Key Value(s) Having Duplicate Row Information
Hi,

I am putting my problem in an example as I Feel it would be clear.

Assume my table PEOPLE is having 4 columns with 6 rows, the SlNo being primary key.
SlNo Name LastName birthdate
1 A B x --
2 C B x |-- 1 pair (A, B, x)
3 D E y --|------------
4 A E y | |
5 A B x __| |-- 2'nd pair (D, E, y)
6 D E y ---------------
In this scenario, I need to find SlNo values having similar values in other columns. The o/p for above must be:
1
5
0
3
6
0 (0 needs to include in output for distinction in the sets)

(a)IS THIS POSSIBLE TO DO IN ONE SELECT STATEMET? and HOW?
(b)If I create another temp table tempPEOPLE and select distinct row information of the 2'nd, 3'rd and 4'th columns from the PEOPLE table and
then selecting SlNo's where the information match, I am able to get o/p
1
5
3
6
without 0...and I cannot makeout the distinct sets in this.
HOW DO I FIND THE DISTINCTION IN SETS?

The duplicates that this thread relates to are the kind with duplicate "keyword" entries AND dissimilar field entries; i.e. :

Code:

keyword negative exact broad Phrase
Polo 0 122 4
Polo 0 122 5

I've come up with an SQL query that seems to return all of these duplicates (save one of each type- the 'real', unique entry). However I think I made the query very inefficient. My SQL is very bad; this query will be running over tens of thousands of rows, so if it can be at all optimized I would greatly appreciate your help!

What I have so far is:

Code:

string query1 = "SELECT * FROM TableName" +
" WHERE EXISTS (SELECT NULL FROM TableName" + " b" +
" WHERE b.[keyword]= " + "TableName"+ ".[keyword]" +
" AND b.[negative]<> " + "TableName"+ ".[negative]" +
" ORb.[keyword]= " + "TableName"+ ".[keyword]" +
" ANDb.[exact]<> " + "TableName"+ ".[exact]" +
" ORb.[keyword] = " + "TableName"+ ".[keyword]" +
" ANDb.[broad]<> " + "TableName"+ ".[broad]" +
" ORb.[keyword]= " +"TableName"+ ".[keyword]" +
" ANDb.[phrase]<> "+"TableName"+ ".[phrase]" +
" GROUP BY b.[keyword], b.[broad], b.[exact]" +
" HAVING Count(b.[keyword]) BETWEEN 2 AND 50000)" ;

the algoritm seems to check every column of every row in order to determine a duplicate. Seems straightforward to me, but alas slow...

Is there a better/faster way I can do this? Thanks for you help!

Comparing Similar Tables - Removing Duplicate Or Repeated Data
It seems that there should be a solution for my situation, but for the life of me I can't seem to figure it out.

I need to compare two "like" tables, containing similar data. Tbl 1 is "BOOKED" (which is a snapshot of inventory) and tbl 2 is "CURRENT" (the live - working inventory table). If I write my query as follows the the subsequent result is "duplicate" data.

Code Block
SELECT booked.item, booked.bin, booked.quantity, current.bin, current.quantity
FROM BOOKED
LEFT JOIN
CURRENT
ON booked.item = current.item

No matter what type of join I use, there is duplicate data displayed for each table. For example, if there are more bins in the BOOKED table that contain a certain product then the CURRENT table will repeat data and vica versa.

As follows:

Item
Bin
Quantity
Bin
Quantity

12345
A01
500
A01
7680

12345
B01
6
A01
7680

12345
C01

A01
7680

54321

98765
Y15
2500
Y15
3000

98765
X10
1200
Y15
3000

What I would like to do is display Bin and Quantity only once and the repeating values as NULL or [BLANK]. Or, to display all of the bins from both tables and only the quantities from each table in relation to the bin found in that table, returning a "0" if no quantity exists.

This is what I'm after:

Item
Bin
Quantity
Bin
Quantity

12345
A01
500
A01
7680

12345
B01
6
B01
0

12345

98765
Y15
2500
Y15
3000

98765
X10
1200
X10
0

Is this possible? If so, how?

I also might add that it is ok for each table to contain multiple entries for any given item. This is basically being requested as an inventory variance report - inventory before physical count and immediatly after physical count - and will only be run once a year.

-----------------------------------------------
Just thinking out loud here:
What if I created three subqueries, the first containing only BOOKED information, the second containing only CURRENT information and the third being a UNION of both tables? Something like this:

Code Block
SELECT q3.bin, q1.item, ISNULL(q1.quantity, 0) as QTY_BEFORE, ISNULL(q2.quantity, 0) as QTY_AFTER

FROM

(select item, bin, quantity
from BOOKED)q1
Left Join

(select item, bin, quantity
from CURRENT)q2
on q1.item = q2.item
Left Join

(select bin, item
from BOOKED
UNION
CURRENT)q3
on q1.item = q3.item

Order By q1.item

I don't know if I wrote the UNION statement correctly, but I will have to try this when I get back to work...

Any suggestions?

Who's Smart Enough To Figure This Out?
Hello All,

I've been trying to get a range of values out of my SQL Server 2000 db without sucess. The field in question has the data type of char(8) and looks like this:

House_numbr_pub (leading spaces in front of each value)
140A
140
141
142
143
144
145
146
147
148
149
150
151
.
.
.
14500
.
.
.

Does anyone know how write a sql statement that will return 140-150, but excluding the ' 14500' and 100-1000. I tried the following where clause to return a range between 100-1000.

WHERE (cook.STREET_PUB LIKE 'lincoln%') AND (LEN(LTRIM(cook.HOUSE_NUMBR_PUB)) BETWEEN 3 AND 4) AND (
(LTRIM(cook.HOUSE_NUMBR_PUB) >= '100') and (LTRIM(cook.HOUSE_NUMBR_PUB) <= '1000') )

This where clause only return two records (100 and 1000). I want it to return 100-1000.

I also tried the following where clause:

WHERE LTrim(cook.HOUSE_NUMBR_PUB) like '1[45][0-9]'
OR
LTrim(cook.HOUSE_NUMBR_PUB) like '1[45][0-9]'

However, building this on the fly with .net will take some effort if someone is trying to search range 1-10000000.

Please Help,

James

Writing Smart SQL
Is it possible to do the following without cursors or creating an identity column:

I have a table from legacy data with ~ 1 million records. I need to insert this into the new table which has a unique varchar(11) key. For the new system this key is generated by calling a SP that returns the next key in sequence. To put the legacy data records in the same table I want to first create a new column at end of legacy data table and populate this using SQL without going thru using cursor and calling the SP for each and every record to get a unique varchar(11) key.

In short here is what I want:

Field1 Field2 varchar(11)key

------ ------ -----------

jsdhf dsf99 1LEG

878jh whjhj 2LEG

8728jh whjhj 3LEG

8578jh whjhj 4LEG

6878jh whjhj 6LEG

8508jh whjhj 7LEG

...

...

...

4878jh whjhj 1000000LEG

How do I generate this key using an SQL stmt?

Smart Aggregation
I'm having problems implementing the following in reporting services 2005.

My hierarchy looks like this (just to illustrate the problem...):

University->Student->Exam

My query returns the following fields:

University,Student,StudentPayment,ExamName,ExamScore

I need to create a report that will show the hierarchy and to smartly aggregate the StudentPayment to both the Student and the University levels.

The problem is that the StudentPayment field is being multiplied by the number of exams in the upper level aggregation.

If only I could set the granularity level of the StudentPayment measurement...

Note that I don't have access to the query, so I can't change anything on that front.

Thanks,

Smart Trigger...
Hello forum.
I have a problem that is kill me.
Initial dates: a table (Tbl_1) to collect dates from users (within form in VB), a view (View_1) to compute some columns (is a part from business€™ logic) and a table (Tbl_2) designated for a trigger.
I will try to resume the contents of above table€¦
create table Tbl_1
(
id int not null,
code varchar(10) null,
TBO int not null,          -- (Time between Overhauling)..hours (life cycle)
T_Hrs_AtLastOvh int null, -- total running hours from last overhauling
TRH int null,              -- total running hours (the life of equipment)
)
GO
Create view View_1
as
select code, [TBO]-([TRH]-[T_Hrs_AtLastOvh])as HrsTo_NextOvh
from Tbl_1
GO
create table Tbl_2
(
id int not null,
code varchar(10) null,
Start_dt smalldatetime,
Stop_dt smalldatetime,
)
GO
--drop table Tbl_1
--drop view View_1
--drop table Tbl_2

Let to insert some dates into Tbl_1:

Insert into Tbl_1
select 1,'cod1',2000,2500,3000
union all
select 2,'cod2',3000,4000,7000
union all
select 3,'cod3',1000,2000,2000
union all
select 4,'cod4',1500,3000,3000
GO
The result of View_1 is in Fig.1:


Fig.1

cod1

1500

cod2

0

cod3

0

cod4

2500

cod1

1500

cod2

3000

cod3

0

cod4

2500

Fig.2

The operator perform requested job for the equipment and the life cycle starts counting again. Suppose to have:

Update Tbl_1 set T_Hrs_AtLastOvh=7000 where id=2
GO
The result of View_1 is Fig.2.
I wish to insert (within trigger) into table Tbl_2 all codes that have [HrsTo_NextOvh]=0 from View_1 and automatic to record the date when the record is done with a propertie like €™starting job€™.
After the operator executed the job, he will update the Tbl_1 (the result is in Fig.2) and the trigger has to record this process with the propertie like €˜completed job€™.
Depending by the time between overhauling and the operating hours of equipments, this task happens more or less often.
My intentions are to record the time requested to executed a job and to make a history of events.

Any suggestion to solve my problem is full apreciated.

Thoughts About The Smart Way To A Task
I'm still a database newbie so I would like to solicit thoughts aboutthe smartest way to do something in sqlserver.My company has a web application that we customize for each client.We can do this because everything is database driven. We havedatabase tables that contain our HTML and database tables as well assome standard tables for each database. We have an in house app thatlets us tweak both of these things and creates a new web site anddatabase tailored to each project.Each of these sites has a table that stores a schedule are clientsuse.The records in this schedule table change when information in othercustom generated tables change.My company currently uses a legacy foxpro app to update the scheduletable.The foxpro app contacts sqlserver, reads a table with a list of tablesand scheduling information to check, checks each of those items andupdates the schedule table.I would like to lose the foxpro app.At first thought.........as a database newbie.......putting triggersin each of the tables to update the schedule when something changesseems the way to go.However, since we change a part of the schema ( we have an app thatgenerates the database tables unique to each client ) for each clientI would like a scheme that would not involve having to create adifferent trigger for each new table.I would also like something that updates in real time. Right now thefoxpro app is executed once a day.I was thinking of making a large stored procedure and putting anidentical call to that procedure in each table.Each table would have the same trigger in it that would get fired whenthe record was altered. It would call the stored procedure withrelevent arguments to update the schedule.Does this sound like a smart way to solve this problem or am I notthinking "database enough"?Any thoughts are welcome.I would like to build a better solutionSteve

Win CE 4.2 And Smart Dev Application Question
I'm a bit stuck with this one... hope someone can help.

I'm trying to develop an application that will run on a pocket PC with Windows CE 4.2

I'm using .Net 2003 and the application is in VB.Net.

I can run the application on the pocket pc fine (ie. form paints, buttons work) , until I need to connect to Sql DB on the server.

When I try to create a connection object (Dim dbconnection As New SqlClient.SqlConnection)

I get an error stating .. "This application (test.exe) requires a newer version of .Net Compact Framework than the one installed on the device" .... "could not load System.Data.SqlClient.SqlConnection from assembly System.Data.SqlClient Version=1.0.5000.0"

The version that it is looking for is. 1.0.5000.0 . The VS2003 is using this version.

I've downloaded the compact framework v1. sp3 , ran all the cabs on the Win CE device ... it looked that it installed fine.... but the problem still exists.

Help Please..

Why Optimizer Is Not Smart? Is Dynamic SQL My Only Option...

On the same topic does this mean all OR conditions areALWAYS verified regardless if one of them has already been determinedto be True?Thank you

My First Post: Smart SQL Updating Technique..??
Hello geniuses

First of all I would like to announce that this is my first time I post here.. However, I'm pretty sure that I'm in the best place to ask what I want. To cut the story short, I'm querying SQL database on a remote machine and having the result saved (mapped) to another table on another database on the same remote machine. The thing is the destination table was empty before the query was run the first time. I have been searching for some smart way so that when I modify the source tables that my query is based on, it doesn't affect except the modified rows. In other words, it should be like if the row is already there, do nothing. otherwise, it updates the existig record. else, it's a new record and it's inserted. I think what i need will include some coding for sure, yes? I don't know if i'm clear about the requirement or not though! but I know that you are experts and can direct me. Waiting for your valuable replies.

Smart Device Replication Monitor
Is there any way how to monitor Subscription to SQL Server 2005 from a smart device application? Something like MS sample application at http://msdn2.microsoft.com/fr-fr/library/ms146899.aspx

Replication monitor is monitoring subscriptions, but when I replicate etc. 20 000 updates made on SQL Server to SQL Server CE on the device it returns that they were send in etc. 5 seconds, but the whole process with initialization takes 4 minutes. I dont think that this process would take 5 secs. I know there is a way how to monitor subscription from Subscriber (T-SQL, RMO) but these are for windows app not for smart device.

SQL SERVER EXPRESS - Vb.net/smart Client
Hey all... great site!

Here's what I'm going for:

I have an 05 VB.NET windows application that will be used as a smart client for our folks in the field. The windows application includes 05 SQL Server Express. I have included in the Data Sources of my project and attached file going through the wizard Microsoft SQL Server Database File (SqlClient) ='s (myfile.mdf) and then selected all tables, views, stored procedures, and functions... the corresponding myfileDataSet.xsd with the myfile.mdf are now located in the root of the project. I now recompile the project without error and go to the properties section Publish tab... select the Application Files button and myfile.mdf Publish Status is set to Include and the Download Group set to Requried. With this in place I right click on the myfile.mdf from the Soultion Explorer and under the properties section have set the build action to compile and use the copy always setting for the Copy to Output Directory.

My app.config looks like this:

<configSections>
<sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
<section name="myfile.My.MySettings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" />
</sectionGroup>
</configSections>
<connectionStrings>
<add name="myfile.My.MySettings.ffgscrmConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|myfile.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True"
providerName="System.Data.SqlClient" />
</connectionStrings>

After the publish is completed on the client machine... install for Windows Installer 3.1, SQL Server Express, and the Windows Application contains no data but everything else works fine.

My problem is that I need to attach the myfile.mdf to the new SQL Server Express instance on the client machine during the installation process so that when the application fires it will be pointed to the above location on the client.

Any ideas... scripts... includes for an ApplicationEvents.vb on how to do this? Thanks a ton... :)

Kind regards,

BillB

CREATE TABLE DUPLICATE OBJECT/DUPLICATE FIELD NAME ERROR Msg 2714
Hello Everyone:

I am using the Import/Export wizard to import data from an ODBC data source. This can only be done from a query to specify the data to transfer.

When I try to create the tables, for the query, I am getting the following error:

Msg 2714, Level 16, State 4, Line 12

There is already an object named 'UserID' in the database.

Msg 1750, Level 16, State 0, Line 12

Could not create constraint. See previous errors.

I have duplicated this error with the following script:

USE [testing]

IF OBJECT_ID ('[testing].[dbo].[users1]', 'U') IS NOT NULL

DROP TABLE [testing].[dbo].[users1]

CREATE TABLE [testing].[dbo].[users1] (

[UserID] bigint NOT NULL,

[Name] nvarchar(25) NULL,

CONSTRAINT [UserID] PRIMARY KEY (UserID)

)

IF OBJECT_ID ('[testing].[dbo].[users2]', 'U') IS NOT NULL

DROP TABLE [testing].[dbo].[users2]

CREATE TABLE [testing].[dbo].[users2] (

[UserID] bigint NOT NULL,

[Name] nvarchar(25) NULL,

CONSTRAINT [UserID] PRIMARY KEY (UserID)

)

IF OBJECT_ID ('[testing].[dbo].[users3]', 'U') IS NOT NULL

DROP TABLE [testing].[dbo].[users3]

CREATE TABLE [testing].[dbo].[users3] (

[UserID] bigint NOT NULL,

[Name] nvarchar(25) NULL,

CONSTRAINT [UserID] PRIMARY KEY (UserID)

)

I have searched the "2714 duplicate error msg," but have found references to duplicate table names, rather than multiple field names or column name duplicate errors, within a database.

I think that the schema is only allowing a single UserID primary key.

How do I fix this?

TIA
