I have this query and it works except for I am getting duplicate primary keys with unique column value. I want to combine them so that I have one primary key, but keep all the columns. Example:
Key column 1 column 2 column 3 column 4
A 1 1
A 2 2
B 2 3
B 5 5
it should look like:
A 1 1 2 2
B 2 3 5 5
Here is my query:
SELECT *
FROM [TLC Inventory].dbo.['2014 new$']
WHERE [TLC Inventory].dbo.['2014 new$'].mis_key LIKE '2%'
AND dbo_Product_Info#description NOT LIKE 'NR%'
AND dbo_Line_Info#description NOT LIKE 'OBSOLETE%'
I'd like to throw this idea 'out there' to see if I'm missing something I'll later regret.
I'm looking to resolve a scalability issue within our point-of-sale program. Currently the PK on transactional tables (sales and orders) is created by the application layer using a 'MAX(PKCol) + 1' mechanism. Obviously this requires that all users of the system, whether they're local or remote, have current data at any time they wish to insert. It's this limitation I'd like to remove. Most sites are using MS SQL Server 2000. No sites use anything specific to a later version.
By having a PK that can be generated independently of a 'master' database we can overcome this issue. The PK values will need to be unique within a 'group' of shops and able to be generated by a program operating at any level. From 'head office' which manages a number of shops, to the server at a given shop and even the register / till itself should be able to create ID's while disconnected from the server (using a local database).
It seems there's three main ways to accomplish this: - Identities, - MachineID, CurrentPK composite. - GUID's
Identities: I've ruled out identities as I believe the administration overhead of dealing with them makes them impractical (there may be several hundred registers and therefore as many ranges to be set up within a group).
MachineID, CurrentPK composite: The MachineID references a Machine table which has an entry for each ethernet MAC address which connects to the database. The reason I chose to store the MAC in another table rather than simply using it as column is that I'm fetching it from sysprocesses.net_address(nchar(12)) and believe it's computationally cheaper to use an int than a text column. This mechanism means that we can still expose the PK to the user in some cases (eg: InvoiceNumber printed on a receipt). When the local database is not up to date (usually due to network problems) there will be cases where the CurrentPK will be duplicated but kept unique since it's coupled with the new MachineID. The big drawback to this method is that all current code will need to be revised to deal with the composite keys (this will be a significant amount of development).
GUIDs: Ugly to look at and time-consuming to type. They're not something which you'd expose to a user unmodified so realistically this means altering existing code to use a new 'user friendly' number where the PK is currently exposed to them. The use of GUIDs rule-out the use of clustered indecies on tables they're the PK for lest most inserts cause a page split. The splits would also necessitate more frequent index defrags / rebuilds. Using a non-clustered index incurs a penalty Vs a non-fragmented clustered one (doesn't it?) so while this avoids page-splits it comes at a cost.
After all that I think the best solution is to use GUIDs with a non-clustered index for each of the PK's. While it might not be the fastest of the options (slower reads/joins Vs composite PK) it will be significantly faster to develop while maintaining acceptable performance.
I know this is probably a flick of a switch but I cannot figure out which switch. Setup is SQL Server / Stored Procedures / DAL / BLL(skipped for testing) / PL. The stored procedure queries from only one table and two columns are ignored because they are being phased out. I can run the stored procedure and preview the data in the DAL but when I create a page with an ODS linked to the DAL and a GridView I get this error. I checked every column that does not allow nulls and they all have values. I checked unique columns (ID is the only unique and is Identity=Yes in the table definition). I checked foreign-key columns for values that are not in the foreign table and there are none. Any ideas why do I get this? Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.
Hi, I am getting the above error when trying to load a report into my Web Application, I have tracked the error down to one specific field in my database. Even though this field is a NVarChar field and is of size 30 it would seem that there is an issue returning the value from the field. I can write it into the database no problems but when I try to get it out of the database it returns the above error. e.g MOB 401.908.804 - Fails 0401.907.324 - okay 8239 9082 (pager) - fails Anyone got an idea on how to fix this???? Regards.. Peter.
I have a query that I'm working on, but instead of giving the query, I wanted to ask a basic syntax question. If more info is needed, let me know. If you have 2 rows that have a common relationship, but differing information in some fields, can you merge them all onto one row? I've done this with Sum(case) expressions, but I don't want to 'add' anything. In the following example, the ActivityID refers to a break. ActivityID can be:
0=Pick up 1=Drop Off 2=Lunch 3=Break
So if I wanted to see 2 breaks on 1 row in the following example, would this be possible:
I'm using a shipping program called endicia professional that allows for database manipulation to make my processing easier. I've managed to fix the database here and there but have had an issue combining orders from a single customer when theybuy more than one item. Ideally I would like to have it combine rows when a customer purchases items going to the same address. To avoid having an issue where the address line is the same ie two people live in the same appt complex and it combines these I thought we could use qualifiers as the purchase will have name, order Id that should be unique enough
Order-id name address sku 1234 John 46 easy ln. A27 1234 John 46 easy ln. B32
Results: Order-id name address sku 1234 John 46 easy ln. A27,b32
Hi Im having trouble with this it seems simple enough but its not!
I have a source Table called Access_table example
Name Role1 Role2 Role3 Role4 Role5 a 1 0 0 0 0 a 0 0 1 0 0 b 1 0 0 0 0 c 0 1 0 0 0 d 0 0 0 0 1 e 0 0 1 0 0 e 0 1 0 0 0 f 1 0 0 0 0 g 0 0 1 0 0
I need to create a view that basically finds all the names with double Roles and merge the results into 1 row example. Name Role1 Role2 Role3 Role4 Role5 a 1 0 1 0 0 e 0 1 1 0 0
I cannot change the information in the source table and the results need to be in a view as the roles will change. Every time I try and do this I duplicate the row again. Can anybody suggest a solution.

Hello Experts, Been struggling with this issue all morning and beginning to get a headache. Essentialy my problem is this. I have a gridview control that ive bound to datasource where the select statement is using an inner join to retrieve textual info from one table in refernce to an object_id contained within both. i.e SelectCommand="SELECT 'multiple fields from both tables'FROM ZCRMTAB_ACTIVITY INNER JOIN ZCRMTAB_ACT_LOG ON ZCRMTAB_ACT_LOG.OBJECT_ID = ZCRMTAB_ACTIVITY.OBJECT_ID WHERE (ZCRMTAB_ACTIVITY.REF_CUST_NO = @REF_CUST_NO) ORDER BY ZCRMTAB_ACTIVITY.CREATED_AT DESC"> <SelectParameters><asp:QueryStringParameter Name="fieldName" QueryStringField="value" Type="String" /> My problem is that this returns individual row results and are displayed on individual lines. Where the object_id is the same i want all the textual info to be displayed within the same row. Does anyone know how i can accomplish this? Thanks in advance
i'm new to this and i am trying to create a statement that would add the values together for Hong Kong and China and then delete the Hong Kong road. (this is a example what i am trying to acheive)
I am still fairly new to SQL, having been tasked with creating a csv file from data now someone else has left.
I can do the csv export using sqlcmd and I have the query sorted and am pulling out the right data, but it generates two rows, as one of the tables has multiple records per cardholder. See the query below, I know there is a way of doing it with XML PATH, I think, but it has got me slightly confused.
I have 2 columns (ID, Msg_text) in a table where i need to combine every 3 rows into single row. What would be the best option i have? I know by using 'STUFF' and 'XML PATH' i can convert all the rows into a single row but here i'm looking for every 3 rows into a single row.
I have a source table in the staging database stg.fact and it needs to be merged into the warehouse table whs.Fact.
stg.fact is not a delta feed it is basically an intra-day refresh.
Both tables have a last updated date so its easy to see which have changed.
It will be new (insert) or changed (update) data that I am interested in, there are no deletions.
As this could be in the millions of rows that are inserts or updates then this needs to be efficient.
I expect whs.Fact to go to >150 million rows.
When I have done this before I started with T-SQL Merge statement and that was not performant once I got to this size.
My original option was to do this is SSIS with a lookup task that marks the inserts and updates and deal with them seperately. However I set up the lookup tranformation the reference data set will have a package variable in the SQL commnd. This does not seem possible with the lookup in 2012! Currently looking at Merge Join transformation and any clever basic T-SQL that could work as this will need to be fast, and thats where I think that T-SQL may be the better route.
Both tables will have >100,000,000 rows Both tables have the last updated date The Tables are in different databases but on the same SQL Instance Each table holds 5 integer columns, one Varchar, one datatime
Last time I used Merge it was a wider table with lots of columns so don't know if this would be an option.
I have the following variables VehicleID, TransactDate, TransactTime, OdometerReading, TransactCity, TransactState.
VehicleID is the unique vehicle ID, OdometerReading is the Odometer Reading, and the others are information related to the transaction time and location of the fuel card (similar to a credit card).
The records will be first grouped and sorted by VehicleID, TransactDate, TransactTime and OdometerReading. Then all records where the Vehicle ID and TransactDate is same for consecutive rows, AND TransactCity or TransactState are different for consecutive rows should be printed.
I also would like to add two derived variables.
1. Miles will be a derived variable that is the difference between consecutive odometer readings for the same Vehicle ID.
2. TimeDiff will be the second derived variable that will categorize the time difference for a particular vehicle on the same day.
My report should look like:
VehID TrDt TrTime TimeDiff Odometer Miles TrCity TrState 1296 1/30/2008 08:22:42 0:00:00 18301 000 Omaha NE 1296 1/30/2008 15:22:46 7:00:04 18560 259 KEARNEY NE
What would be the best way to insert unique values into a table/unique column ? I cannot make that table/unique column as indentity. Right now, I use a staging table with indentity column, insert rows then insert rows back to final table.
Hi,I have two tables such that in each table I need to make sure thatcolumn x in table A and column y in table B have a unique valuesmeaning that a user cannot insert a value to column A if its alreadyexist in column B and vice versa.How can I enforce it? Please remember that this two different tables.Thanks,Ori.
Hi, I have been asked to write some code that can check a large table for duplicate values in a non pk column. The table may have up to 1000000 rows. The PK column is an auto increment field. For performance reasons the column in question could not be set to unique values only for inserts, an algorithm is used to create unique no's before the insert but what I am doing is double checking that their have been no duplicates created accidently. If their are duplicates I need to know what rows they occurred on.
I have a large table that consists of the columns zip, state, city, county. The primary key "zip" has duplicates but the rows are unique. How do I filter out only the duplicate zips. Randy Garland
I want BetId 500 and 502 to be returned as result if i give select criteria where game id = 108,109. Pls.Note: It should not return BetId 501 in the result, since it belongs to different combination(108,109,110). Similarly if i give, select criteria where game id =(108,109,110) it should return BetId 501.not the 500 and 502..which is different combination..
Hope i clarified my problem..pls help me in this regard.Thanks a lot...
I am trying to do a join which involves more than 3 tables. One is a parent table and the other two table have 1:n relationship with that parent table.
But duplicate records are being returned in the resultset. How do I eliminate duplicate records?
This is my query.
SELECT table1.* from table1 left outer join table2 on table1.id=table2.id left outer join table3 on table1.id=table3.id
I tried doing DISTINCT here but with no success.
SQL with distinct clause.
SELECT distinct table1.id, table1.* from table1 left outer join table2 on table1.id=table2.id left outer join table3 on table1.id=table3.id
This is the error I get: The text data type cannot be selected as DISTINCT because it is not comparable
SELECT DISTINCT patient.patientID, patientFirstName, patientLastName, patientDOB, patientGender, completed_date FROM patient LEFT JOIN patient_record ON patient_record.patientID = patient.patientID WHERE (sub_categoryID = 4 OR patient_record.allocated = 4) AND (patient_status = 1 OR patient_status = 2 OR patient_status = 5) GROUP BY patient.patientID, patientFirstName, patientLastName, patientDOB, patientGender, completed_date
This brings up duplicate records, my aim is to bring distinct records, now if I take out the other returned fields after patientID and using the following sql:
SELECT DISTINCT patient.patientID FROM patient LEFT JOIN patient_record ON patient_record.patientID = patient.patientID WHERE (sub_categoryID = 4 OR patient_record.allocated = 4) AND (patient_status = 1 OR patient_status = 2 OR patient_status = 5) GROUP BY patient.patientID
This bring up distinct results, but I need to retrieve the other fields from the database i.e. patientFirstName and patientLastName
Item Color Quantity -------------------- -------------------- -------------------------- Table Blue 10 Table Red 20 Table Yellow 30 Chair Blue 40 Chair Red 50
I'm wondering if there is a group state like this: Select Item, ?Function(Color), Sum(Quantity) From Inventory Group by Item which returns this:
I need a query to return two values. One will be the total units and the other will be total unique units. See exmaple data below. It does not have to be one query. This will be in SP, so I can keep it seperate if I have to.
Total Units = 7 - easy to do by using count() Total unique units = 4 - I cannot use group by as it would return multiple results for each unit, which is not what we want.
