I have a stored procedure that executes a transaction which updates/inserts into a table on a remote server and should then use that new entry's autogenerated primary key to update another table.
I try to store that key into a variable called @.NewlyCreatedPastelDClinkNumber but to no avail
I have used the @.@.Identity approach and now try to manually get that key to from other information but still no go..My thinking is: since i am using transactions, maybe the entry cant be found until the transaction has been committed...but surely it should find it after the commit statement? Here is my code: I have marked the interesting bit with blue for simplicity.
ALTER procedure [dbo].[inv_SynchronizeClientsWithPastel]

Problem 1)
IF Exists(SELECT DCLink from [server].[Satra Corporate (Pty) Ltd].dbo.Client WHERE DCLink = @.PastelDCLinkNumber)
--Update the Pastel Client table
Begin
Update [server].[Satra Corporate (Pty) Ltd].dbo.Client SET
Don't check for the data and then do the update. Simply DO the update first. If you update 0 rows, then you do the insert. This cuts exection in half when there is an update to be performed.
Problem 2)
IMMEDIATELY after the INSERT, put the @.@.ERROR and @.@.ROWCOUNT AND scope_identity() values into a variable. Then act on those three in appropriate order.
Problem 3)
You should use a remote sproc to do the update/insert stuff on the remote server. MUCH more efficient. Pass parameters in and then local stuff does work with a cached query plan and only one network trip.
|||Thanks for all your support. I'm going to give this a try|||Thank you for all your help. It worked.I looked at your suggestions in your steps(problems) and immediately saw the advantages of your suggestions.
I will now adapt future stored procedure's templates to include those good practices. Thanks once more.
Regards
Mike
