So do you only ever insert one row at a time?  Is it during the insert itself that you experience the poor performance, or during the duplicate checking?

You will need to build a script dynamically.  Something like this rough-and-ready effort, which generates a script that returns all rows where at least one of the columns has a...

So you're doing this once for every row you're inserting into the table?  Are you using a cursor or a WHILE loop to do that?  I think this is probably...

OK.  Can you please put a PRINT @Query3 statement just before the EXEC command and post the result of that.

Thanks

John

Probably what you need, then, is to create a trigger in the table that checks the time of the previous insert, and if it was less than ten minutes ago,...

How many columns are in the result set when you run sp__DBBackupInfo on the remote server?

I'm sorry, I don't know anything about Materialized views in Oracle so I can't advise you on that.

If you had a unique constraint on CUST_PRODUCT_ID, ATTRIBUTE_ID and DATA then that...

Would this not work?

SELECT Titleid AS tit FROM title WHERE Titleid=11

What are the circumstances under which you wish to discard the less recent value?  Is it when it is less than an hour before the previous one?  Or is it...

Raj

OK.  It looks as if your database design here is not ideal.  There is no primary key constraint on the table.  Is there a column (or combination of columns) that...

Perhaps you ought to include a "USE DBName" statement at the beginning of @Query2.  If that doesn't work, please post the result of this query:

USE DBName

SELECT COLUMN_NAME

FROM INFORMATION_SCHEMA.COLUMNS

WHERE...

So you have several temp tables, all with the same structure, but each named according to a user in the database?  My advice would be to normalise your design so...

Raj

Please will you post the table DDL so that we can see what constraints you have on the data (primary keys and so on).

Thanks
