Along with the error number, information that relates to the error is returned.

Returning from a procedureThe following example shows if no user name is specified as a parameter when findjobs is executed, RETURN causes the procedure to exit after a message has been IF XACT_STATE() <> 0 BEGIN ROLLBACK TRANSACTION; END EXECUTE dbo.uspLogError @ErrorLogID = @ErrorLogID OUTPUT; END CATCH; -- Retrieve logged error information. IF @SalesYTD IS NULL RETURN(4) ELSE -- SUCCESS!! The PRINT statement is not affected by TRY blocks, while a RAISERROR run with a severity of 11 to 19 in a TRY block transfers control to the associated CATCH block.
Returning status codesThe following example checks the state for the ID of a specified contact. A FOREIGN KEY constraint on the table prevents the DELETE statement from succeeding and a constraint violation error is generated. more stack exchange communities company blog Stack Exchange Inbox Reputation and Badges sign up log in tour help Tour Start here for a quick overview of the site Help Center Detailed
The message of the error is returned. SELECT 1/0; END TRY BEGIN CATCH SELECT ERROR_NUMBER() AS ErrorNumber ,ERROR_SEVERITY() AS ErrorSeverity ,ERROR_STATE() AS ErrorState ,ERROR_PROCEDURE() AS ErrorProcedure ,ERROR_LINE() AS ErrorLine ,ERROR_MESSAGE() AS ErrorMessage; END CATCH; GO Examples: Azure SQL RAISERROR (@ErrorMessage, -- Message text. @ErrorSeverity, -- Severity. @ErrorState -- State. ); END CATCH; E. Sql Server Stored Procedure Return Value 0 This documentation is archived and is not being maintained.
Specify a severity of 10 or lower to use RAISERROR to return a message from a TRY block without invoking the CATCH block.Typically, successive arguments replace successive conversion specifications; the first Sql Return Value From Stored Procedure SELECT * FROM dbo.ErrorLog WHERE ErrorLogID = @ErrorLogID; GO Nested Error-handling ExampleThe following example shows using nested TRY…CATCH constructs. You’ll be auto redirected in 1 second. For example, the CATCH block of an outer TRY...CATCH construct could have a nested TRY...CATCH construct.
We appreciate your feedback. Sql Error Codes COMMIT TRANSACTION; END TRY BEGIN CATCH -- Call procedure to print error information. These errors will return to the application or batch that called the error-generating routine. Error functions can be referenced inside a stored procedure and can be used to retrieve error information when the stored procedure is executed in the CATCH block.

Sql Throw Error Along with the error number, information that relates to the error is returned.
Values larger than 255 should not be used.If the same user-defined error is raised at multiple locations, using a unique state number for each location can help find which section of Sql Server Return Codes Why can't the second fundamental theorem of calculus be proved in just two lines? EXECUTE usp_MyError; END TRY BEGIN CATCH SELECT ERROR_NUMBER() AS ErrorNumber, ERROR_MESSAGE() AS ErrorMessage; END CATCH; GO Here is the result set.
This first section creates a table that will be used to demonstrate a deadlock state and a stored procedure that will be used to print error information. Because the Database Engine may raise errors with state 0, we recommend that you check the error state returned by ERROR_STATE before passing it as a value to the state parameter SELECT 1/0; END TRY BEGIN CATCH -- Execute the error retrieval routine. Sql Server Stored Procedure Default Return Value PRINT 'Error ' + CONVERT(varchar(50), ERROR_NUMBER()) + ', Severity ' + CONVERT(varchar(5), ERROR_SEVERITY()) + ', State ' + CONVERT(varchar(5), ERROR_STATE()) + ', Procedure ' + ISNULL(ERROR_PROCEDURE(), '-') + ', Line '

Using TRY...CATCH in Transact-SQL Errors in Transact-SQL code can be processed by using a TRY…CATCH construct similar to the exception-handling features of the Microsoft Visual C++ and Microsoft Visual C# languages. When msg_id is not specified, RAISERROR raises an error message with an error number of 50000.msg_str Is a user-defined message with formatting similar to the printf function in the C standard You’ll be auto redirected in 1 second. Whenever I call a stored procedure in real code, I have checks on the return value as well as any new errors that might arise.
