Using @@ERROR The @@ERROR system function returns 0 if the last Transact-SQL statement executed successfully; if the statement generated an error, @@ERROR returns the error number. Who sent the message? All other parts of the error, such as its severity, state, and message text containing replacement strings (object names, for example) are returned only to the application in which they can You’ll be auto redirected in 1 second.

However, here is a fairly generic example: SELECT, INSERT, UPDATE, or DELETE SELECT @[email protected]@ERROR, @[email protected]@ROWCOUNT IF @Rows!=1 OR @Error!=0 BEGIN SET @ErrorMsg='ERROR 20, ' + ISNULL(OBJECT_NAME(@@PROCID), 'unknown') + ' - unable WHILE (@retry > 0) BEGIN BEGIN TRY BEGIN TRANSACTION; UPDATE my_sales SET sales = sales + 1 WHERE itemid = 1; WAITFOR DELAY '00:00:13'; UPDATE my_sales SET sales = sales + Why does Deep Space Nine spin?

Sql Server @@error Message

Returns an error number if the previous statement encountered an error. Not the answer you're looking for? For example, a CATCH block can contain an embedded TRY…CATCH construct to handle errors encountered by the CATCH code.Errors encountered in a CATCH block are treated like errors generated anywhere else. IF @ErrorVar <> 0 BEGIN IF @ErrorVar = 547 BEGIN PRINT N'ERROR: Invalid ID specified for new employee.'; RETURN 1; END ELSE BEGIN PRINT N'ERROR: error ' + RTRIM(CAST(@ErrorVar AS NVARCHAR(10)))

  1. TRY...CATCH also supports an ERROR_NUMBER function that is not limited to returning the error number in the statement immediately after the statement that generated an error.

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. @@rowcount In Sql Server This documentation is archived and is not being maintained. Copy USE AdventureWorks2012; GO UPDATE HumanResources.EmployeePayHistory SET PayFrequency = 4 WHERE BusinessEntityID = 1; IF @@ERROR = 547 PRINT N'A check constraint violation occurred.'; GO B. it always rollbacks at this point, because @@rowcount evaluates the very last statement so it always equals 0.

When a batch finishes, the Database Engine rolls back any active uncommittable transactions. Using @@ERROR to conditionally exit a procedureThe following examples uses IF...ELSE statements to test @@ERROR after an INSERT statement in a stored procedure. IF @@ERROR <> 0 BEGIN -- Return 99 to the calling program to indicate failure. http://u2commerce.com/sql-server/transact-sql-on-error.html EXECUTE sp_addmessage @msgnum = 50010, @severity = 16, @msgtext = N'Substitution string = %s.'; GO DECLARE @ErrorVariable INT; -- RAISERROR uses a different severity and -- supplies a substitution argument.

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. Sql Error 803 Copy USE AdventureWorks2008R2; GO -- Verify that the stored procedure does not exist. SELECT 1/0; END TRY BEGIN CATCH SELECT ERROR_MESSAGE() AS ErrorMessage; END CATCH; GO B.

The stored procedure usp_GenerateError executes a DELETE statement inside a TRY block that generates a constraint violation error.

The error will be handled by the TRY…CATCH construct. This notification is sent in the form of an attention, which is not handled by a TRY…CATCH construct, and the batch is ended. I'm looking for any good ideas and how best to do or improve our error handling methods. Ms Sql Error The following example shows the code for uspPrintError.

The error functions will return NULL if called outside the scope of a CATCH block. Because @@ERROR is cleared and reset on each statement executed, check it immediately following the statement being verified, or save it to a local variable that can be checked later. SELECT @ErrorVar = @@ERROR, @RowCountVar = @@ROWCOUNT; IF (@ErrorVar <> 0) PRINT N'Error = ' + CAST(@ErrorVar AS NVARCHAR(8)); PRINT N'Rows Deleted = ' + CAST(@RowCountVar AS NVARCHAR(8)); GO @@ERROR is IF (XACT_STATE()) = -1 BEGIN PRINT N'The transaction is in an uncommittable state.' + 'Rolling back transaction.'

ERROR_NUMBER has the advantage that it is available to all statements in the scope of the CATCH block, whereas @@ERROR is reset by the first statement in the CATCH block.Conditional statements, The content you requested has been removed.
