Please advice me how to handle this and give me sample code. a fantastic read We will return to the function error_message() later.
Note: the syntax to give variables an initial value with DECLARE was introduced in SQL2008. Sql Server Trigger Error Log I cannot use standard approaches of Sql Server (replication, DTS...) because of different data schema and other restrictions (time to implement, environment issues...).

Is there any guarantee about the evaluation order within a pattern match? Comment: Minor changes. Sql Server Try Catch Throw If we were to execute the SELECT statement again (the one in Listing 4), our results would look similar to those shown in Listing 7. Raiserror In Sql Server Cannot insert duplicate key in object 'dbo.sometable'.

The effects of the transaction are not reversed until a ROLLBACK statement is issued, or until the batch ends and the transaction is automatically rolled back by the Database Engine. The XACT_STATE function determines whether the transaction should be committed or rolled back. Exception Handling In Sql Server
If no error message was sent when the transaction entered an uncommittable state, when the batch finishes, an error message will be sent to the client application. Copy BEGIN TRY -- Generate a divide-by-zero error. But as I mentioned earlier, the rules that govern RAISERROR are a bit quirky. his comment is here Next code shows this mechanism: -- create test table IF OBJECT_ID('dbo.Test', 'U') IS NOT NULL DROP TABLE dbo.Test ; GO CREATE TABLE dbo.Test ( Id INT IDENTITY PRIMARY KEY, NAME NVARCHAR(128)

Listing 3 shows the script I used to create the procedure. He is now a technical consultant and the author of numerous books, articles, and training material related to Microsoft Windows, various relational database management systems, and business intelligence design and implementation. This is not "replacement", which implies same, or at least very similar, behavior. Sql Server Trigger Try Catch Positively!
