After just about every SELECT, INSERT, UPDATE, and DELETE, the @@ROWCOUNT and @@ERROR get captured into local variables and evaluated for problems. have a peek here

In actually, I need only to roll back the transaction and specify the THROW statement, without any parameters. The same rational applies to the ROLLBACK TRANSACTION on the Catch block. More exactly, when an error occurs, SQL Server unwinds the stack until it finds a CATCH handler, and if there isn't any, SQL Server sends the error message to the client. The purpose here is to tell you how without dwelling much on why.

The batch that contains the TRY…CATCH construct is executing at a higher level than the stored procedure; and the error, which occurs at a lower level, is caught.

The error causes execution to transfer to the associated CATCH block inside usp_GenerateError where the stored procedure usp_RethrowError is executed to raise the constraint violation error information using RAISERROR. IF (XACT_STATE()) = -1 BEGIN PRINT N'The transaction is in an uncommittable state.' + 'Rolling back transaction.' ROLLBACK TRANSACTION; END; -- Test whether the transaction is committable.
