How To Pull Isolated Data From Two Tables?
Apr 23, 2006
Hi, I am trying to pull e-mail addresses of certain users from a list of all the users in our company. I have two tables. One contains a single column of only the users I need. The other table contains every user and their e-mail address. Could someone tell me how to pull this data from these two tables. I am new to SQL Query and have been trying to figure out these JOIN statements, but nothing I am doing seems to work.
Thank you,
Lisa

Hi,I have a question regarding best practices in database design. In arelational database, is it wise/necessary to sometimes create tablesthat are not related to other tables through a foreign Keyrelationship or does this always indicate some sort of underlyingdesign flaw. Something that requires a re evaluation of the problemdomain?The reason I ask is because in our application, the user can perform xnumber of high level operations (creating/updating projects, creating/answering surveys etc. etc.). Different users can perform differentoperations and each operation can manipulate one or more table. Thispart of the system is done and working. Now there is a requirement tohave some sort of audit logging inside the database (separate from thetext based log file that the application generates anyway). This"audit logging" table will contain high level events that occur insidethe application (which may or may not relate to a particularoperation). This table is in some sense related to every other tablein the database, as well as data that is not in the database itself(exceptions, external events etc.). For example : it might haveentries that specify that at time x user created project y, at time Auser filled out survey B, at time C LDAP server was down, At time D anunauthorized login attempt occurred etc.As I said, these seems to suggest a stand alone, floating table with afew fields that store entries regarding whats going on the systemwithout any direct relationship to other tables in the database. But Ijust feel uneasy about creating such an isolated table. Another optionis to store the "logging" information in another schema/database, butthat doubles the maintainance work load. Not really looking forward tomaintaining/designing two different schemas.I had a look at the microsoft adventureworks database schema diagramand they seem to have 3 standalong tables - AWBuildVersion, ErrorLogand DatabaseLog (unless i am reading it wrong!)Any advice, Information or resources are much appreciated.

I am trying to create a query that will pull a variety of data from three different tables. I've had to join four tables because one set of data is in a completely different table.
I am expecting one row of data but instead I get 4 rows. I suspect this is because I am joining a table indirectly. Here is the code:
SELECT
SDH.BatchID,
('0' +
CONVERT (varchar (10), SDH.WorkerID)) AS VendorID,
convert(varchar,( dateadd(hour,-1,SHIT.EndDate) ),101)
+ ' - ' + SDH.Description
[Code] ....
There is only one applicable row in SDH, but four rows appear when I run the query. All four rows are identical except for the GL.GLCode column, which lists the three GL codes associated with the DeductionItems table. The fourth row is a duplicate of the third.

I can't see what is going on, this is the situation:
I call the Pull method, specify the table to be affected, the query to be used, the connection string to the remote SQL server, the tracking options (On) and the Error table. The pull method executes with no errors however, no table is ever created. I don't know why, here's what I have done so far:
I read the SQL BOOKS ONLINE help on preparing RDA, I set up the IIS virtual directory for anonymous access and on the connection string I send in the user name and password for the SQL server, I went into the SQL Server and grated access to the user name to the database that I am going to access and I made the user a db_owner.
So, according to SQL BOOKS ONLINE I have everything right however, it won't populate, so right now I am open to suggestions on how to get this to work, heres the code:
------------------------------------------------------------------------------------------------------------------
string rdaOleDbConnectString = "Provider=SQLOLEDB;Data Source=<Server>;Initial Catalog=<DB>; User Id=<User>;Password=<Password>"; (it's not exactly like this, but in it has the proper values)
string connectionString = "Data Source="\Program Files\client\db\MobileDB.sdf"";
SqlCeRemoteDataAccess rda = new SqlCeRemoteDataAccess("http://10.1.1.206/mobile/sqlcesa30.dll",
connectionString);
IList _tableNames = new ArrayList();
IList _queries = new ArrayList();
############
Code that prepares tables and queries
############
for (int counter = 0; counter < _tableNames.Count; counter++)
{
rda.Pull(_tableNames[counter].ToString(), _queries[counter].ToString(), rdaOleDbConnectString, RdaTrackOption.TrackingOn, "MobileError");
}
the For loop runs with no problems but no data is ever put (or tables created) into the Mobile DB.

I have three tables EmpIDs,EmpRoles and LatestRoles. I need to write a select Query to get roles of all employees present in EmpIDs table by referring EmpRoles and LatestRoles.
Where I stuck : The condition is first look into table EmpRoles and if it has more than one entry for a particular Employee ID than only need to get the Role from LatestRoles other wise consider the role from EmpRoles .
Example:
Create Table #EmpIDs (
EmplID int
)
Create Table #EmpRoles (
EMPID int,
[Code] ....
Employee ID 2 is having two roles defined in EmpRoles so for EmpID 2 need to fetch Role from LatestRoles table and for remaining ID's need to fetch from EmpRoles .
My Final Output of select query should be like below.
EmpID Role
1 Role1
2 Role2
3 Role1

I am having problems joining these two tables and returning the correct values. The issue is that i have a work order table and a revenue table. I only want to return the sum of the revenue when the revenue comes after the work order date. That is simple enough, but it gets tricky when there are multiple work orders for the same ID. for those instances, we only want the sum of the revenue if it shows up post the work order date and if it is before any other work order date. So ID 312187014 should only have the 9-5 revenue from below, not the 7/7 or 8/6 revenue because the 8/7 work order date is after those revenue dates and thus will not have any revenue tied to it because there is a 9/3 work order that ties to the 9/5 revenue. Additionally the 412100368 ID has a 7/7 work order that ties to the 7/26 revenue, and the 8/7 work order will tie to the 8/23 and 9/20 revenue
--===== Create the test table with
CREATE TABLE #workorder
(
Id varchar(20),
wo varchar(10),
wodate datetime,
amount float
)
GO
CREATE TABLE #revenue
[code].....

Now I want all the records which belongs to RoleID 1 but if same ID is belongs to RoleID 2 than i don't want that ID.From above tables ID 1 belongs to RoleID 1 and 2 so i don't want ID 1.

I have a several questions with regards to setting up a server to cater for multi tenant database.
I have a requirement to host 100 isolated databases for the purpose of multi user environment where each user has it's own database. This is due to security restrictions that why it was requested to be such.
1. What I'm recommending is to setup servers with 256GB of RAM to host multiple databases. Are there servers which can accomodate 256GB? Is this optimal with regards to performance? Or should I break it down to smaller servers with less RAM?
2. Is there a way to determine the CPU requirements for the DB server, taking for example we have 20 databases per DB instance? Are there any best practices / calculators available?
3. Additionally, data from the 100 DB's needs to be consolidated into 1 central repository for Analytics purposes. What I'm looking at is to utilize SQL Server transaction replication. Is there any drawback with this approach? Are there any other approach we could use to easily replicate data across 100 database back to 1 central repository?

Hi all,
I have following problem:
I'm developing a Windows Mobile application, which is using RDA Pull for retrieving data from SQL Server 2005 database to PDA. Please, see the example:
Code Snippet
using (SqlCeEngine engine = new SqlCeEngine(connStr))
{
engine.CreateDatabase();
}
serverConnStr="Provider=SQLOLEDB;Data Source=.;User ID=sa;Initial Catalog=Demo;Password=xxx";
using (SqlCeRemoteDataAccess rda = new SqlCeRemoteDataAccess(
Configuration.Default.SyncServerAddress, "", "", connStr))
{
rda.Pull("MyTable", "SELECT * FROM mytable", serverConnStr, RdaTrackOption.TrackingOffWithIndexes, "ErrorTable");
}
Everythink works fine, when I use 'sa' user account in serverConnStr.
But, when I change conn string to:
"Provider=SQLOLEDB;Data Source=.;User ID=test;Initial Catalog=Demo;Password=test"
the sqlcesa30.dll cannot connect to SQL Server database.
In the sqlcesa30.log then I found following line:
Code Snippet
2007/04/17 10:43:31 Thread=1EE30 RSCB=16 Command=PULL Hr=80040E4D Login failed for user 'test'. 18456
The user 'test' is member of db_owner, db_datareader and public roles for the Demo database and in SQL Server Management Studio I'm able to login to the Demo database with using the 'test' users credentials and I'm able to run the select command on 'mytable'.
So, what's wrong? Why the sqlcesa30.dll process cannot login to the Demo database, and from another application with using the SAME connection string it works?
Please help.
Thank you.
Fipil.

I'm a bit confused about how ssis handles concurrent package runs
let's say I'm running this package and I 've got 3 variables set in it
VARA
VARB
VARC
and by default they are all set to 0
if I run
dtexec /File "C:ControlRoom.dtsx" /SET PackageVersion_Builder.Variables[VARA].Value;1
dtexec /File "C:ControlRoom.dtsx" /SET PackageVersion_Builder.Variables[VARB].Value;1
dtexec /File "C:ControlRoom.dtsx" /SET PackageVersion_Builder.Variables[VARC].Value;1
I'm expecting to run 3 isloated version of the package with in
first version
VARA=1
VARB=0
VARC=0
second version
VARA=0
VARB=1
VARC=0
third version
VARA=0
VARB=0
VARC=1
but it doesn't seem like doing that the maxconcurrent variable is set to 40 to be on the safe side.
when I run I get
first version
VARA=1
VARB=0
VARC=0
second version
VARA=1
VARB=1
VARC=0
third version
VARA=0
VARB=1
VARC=1
any ideas?

I'm looking for the correct syntax to pull back duplicate vendors based on 6 fields from two different tables. I want to actually see the duplicate vendor information (not just a count). I am able to pull this for one of the tables, something like below:
select *
from VendTable1 a
join ( select firstname, lastname
from VendTable1
group by firstname, lastname
having count(*) > 1 ) b
on a.firstname = b.firstname
and a.lastname = b.lastname
I'm running into issues when trying to add the other table with the 4 other fields.

I have a cluster hosting multiple GP databases and a second for my data-warehouse I am playing around with (personal project).
I have scripts that pull data from all the DB's to input into the DW's tables(Customers,Reps,Hub....)
An example of my branch script :
select interidas BranchID,
cmpnynamas BranchDesc,
address1as BranchAddressLine1,
address2as BranchAddressLine2,
address3as BranchAddressLine3,
zipcodeas PostalCode
from dynamics..SY01500
Where interid in ('comp1', 'comp2', 'comp4', 'comp5')
what would be the best way to using these scripts pull the data to my testDW and not have duplicate data issues?
I was thinking of using a staging DB on the GP cluster and then building an import data package to run nightly. the issue i had was how do i avoid duplicate data ?

what are some common techniques for ensuring an isolated temp table scope? For example, if 2 different sprocs happen to crud a temp table with the same name? I'm guessing that big SQL shops establish a standard for this early on to avoid conflicts between sprocs.

Hi,
Writing a report that displays total hours, etc for each day in a given month and I'm having trouble comking up w/ an elegant solution. Tables are set up like this:
table1 (id, start_date,end_date,submitter)
table2( id,table1_id,start_time,end_time, etc)
Each record in table2 is a child to a parent record in table1 and there may be multiple children for each parent. The "start_time" and "end_time" fields are datatype "datetime" and are stored with actual times (not 12:00:00 AM"). I need the report to display the values for each day in a gridview, etc so I can act upon them from the "RowDataBound" sub (more math, etc). The problem that I am running into is that for records that have multiple children for a given day, I need to sum those results and display the summed data as a single row within the GV - can't seem to work that out - I keep getting every child record displaying as its own row in the GV.
Any thoughts? I'm sure it's probably fairly simple but I am still a beginner...thanks as always

Hello -
I am trying to pull data from SQL Server 2000 database onto my Pocket PC and the simple query works on Northwind sample database but does not on another custom build database. I did test the statement in the SQL Query Analyzer and it works.
The error I get is: "Failure setting up a non parameterized query, possible incorrect SQL query."
I know the code is right - thanks to Rory B's screenscasts. Any guidance will be greatly appreciated!
Thanks!

Here is the code:
private void RdaPull()

engine.LocalConnectionString = localConnection;
engine.CreateDatabase();
engine.Dispose();
//Initialize RDA Object
SqlCeRemoteDataAccess rda = null;
rda = new SqlCeRemoteDataAccess(rdaUrl, localConnection);
rda.Pull ("Customers", "select * from Customers", rdaOleDbConnectionString);
rda.Dispose();

Good Afternoon,
I have recently been tasked to come up with a means by which to create SQL data pulls based on user entries. What I mean by this is, I will have a pre defined SQL data pull set up and the user can then select the criteria upon which to pull said data.
So, say I want to display a table where one of the colums has is the "Year". I dont however want all years of data pulled, only 2005 - 2006. So, in form field 1, I could select start year as 2005 and in form field 2, I could select end year as 2006. This would then give me all data from this table based on that year range, or whatever year range I select and submit.
Is there a way to do this in ASP? I have been reading up on UDF with SQL, but I cant find anything about linking it through the use of web forms or through ASP. Or if there is another way to accomplish this? Any assistance is very much appreciated!

I have an OLAP server and would like to use my Chart FX software without having to purchase the OLAP extensions on the server due to budget restraints (ouch).
I've heard that it is possible (although limited) to attach toan OLAP cube using SQL select statements (not MDX).
Basically, I would like to pull the OLAP data in the relational sense.
Is this possible? If so, are any good articles on this subject?
I'm new to OLAP and would like to transition slowly.

Hi All,
I am working on an application to retrieve data to the windows ce 3.0 handheld from the Sql server database. I am able to retrieve the data from the server using RDA pull method and able to see the data on the local handheld database. To display the retrieved data in the dialog to the user, it requires to query the local databse and get the information and then display the information, which is taking some time.
My question is, to reduce the time and improve the performance , instead of pulling the data to the local table, is there any way to pull the data and have it in memory and display the details to the user?
To develop the above application, I used some of the code to pull the data from the server from the sample application C:Program FilesMicrosoft SQL Server CE 2.0SampleseVCeVCReplRdaHPC. I am developing the application for windows ce 3.0 device using eVC 3.0
thanks

Hi,
I am trying to use RDA.pull to pull data from SQL server 2000 to sql mobile, but it fails when some columns are included in the SQLSelectString, though the datatypes involved are only char, float, smallint and smalldatetime, and nothing is longer than 30. Since there is a very large number of columns, it is difficult to isolate the guilty one by trial and error! Coud someone please help?

I am building RDA process between SQL server and SQL server CE. Since when we use the method 'SqlCeRemoteDataAccess.pull()', the data will be pulled down from SQL server to CE server and a new table is created with some addtional columns. As I only intend to pull the data and never push it back to SQL server, if I pull the data down for the second time, there will be an error saying that table is already existing. I wonder whether I can pull the data to an existing table everytime I do the RDA?

When I execute the package in Debug mode, it works.
I then import the package into SQL Server 2005 and it is showing under Stored Packages --> MSDB - AS400Package
I can right click and Run Package from there and it works fine.
When I set the package up to run as a job, it fails. What I have noticed is that the Sign On that I use in the package shows that there was in "invalid login" after the job fails.
I hope I have this post in the right place and hope I have left enough information behind to help. If not let know what else I need to post. I have only been using Business Intelligence Development for a couple days and SQL Server 2005 for about a week or so. All of the SQL DTS packages that I have created seem to be working fine with their jobs as well as my stored procedures.
Thanks for any help you can give me.

I have to pull data for a report from 11/1/2013 to date. But once we get to 11/1/2014 then the report should pull data from 11/1/2014 to date and so on. Is there a way to do this? I guess I could go in and change the year manually but was hoping that there was a way to do this automatically.
so today would be
tadate >= '11/1/2013'
but at any point between 11/1/2014 to 10/31/2015 it should be
tadate >= '11/1/2014'
and so on...
