GO TRY…CATCH with RAISERRORRAISERROR can be used in either the TRY or CATCH block of a TRY…CATCH construct to affect error-handling behavior.RAISERROR that has a severity of 11 to 19 executed This is just one example of many. The error will be handled by the TRY…CATCH construct. Copy ErrorNumber ErrorMessage ----------- --------------------------------------- 208 Invalid object name 'NonExistentTable'.
Working with the THROW Statement To simplify returning errors in a CATCH block, SQL Server 2012 introduced the THROW statement. Listing 4 shows the SELECT statement I used to retrieve the data. 123 SELECT FullName, SalesLastYearFROM LastYearSalesWHERE SalesPersonID = 288 Listing 4: Retrieving date from the LastYearSales table Not surprisingly, the The examples are based on a table I created in the AdventureWorks2012 sample database, on a local instance of SQL Server 2012. CREATE PROCEDURE usp_ExampleProc AS SELECT * FROM NonexistentTable; GO BEGIN TRY EXECUTE usp_ExampleProc; END TRY BEGIN CATCH SELECT ERROR_NUMBER() AS ErrorNumber ,ERROR_MESSAGE() AS ErrorMessage; END CATCH; Uncommittable Transactions and XACT_STATEIf an https://msdn.microsoft.com/en-us/library/ms188790.aspx
Copy CREATE PROCEDURE [dbo].[uspLogError] @ErrorLogID [int] = 0 OUTPUT -- Contains the ErrorLogID of the row inserted -- by uspLogError in the ErrorLog table. Logging the error is all well and good (and very much best practice) but you MUST report back to the caller. The usual 'gotcha' is than most developers expect SQL to behave like procedural languages and offer logical operator short-circuit, but it does NOT. I'm not sure I like it, but it might be useful to know of, some day.
SET @ErrorSave2 = @@ERROR; -- If second test variable contains non-zero value, -- overwrite value in first local variable. PRINT N'Starting execution'; -- This SELECT statement contains a syntax error that -- stops the batch from compiling successfully. The text includes the values supplied for any substitutable parameters such as lengths, object names, or times.ERROR_SEVERITY() returns the error severity.ERROR_STATE() returns the error state number.ERROR_LINE() returns the line number inside T-sql @@error INSERT #tres(ID) VALUES(1); END TRY BEGIN CATCH raiserror(50001,16,1,’Test Second’) –just raises the error END CATCH; select ‘Second: I reached this point’ –test with a SQL statement print ‘Second End’ END go

SET @ErrorLogID = 0; BEGIN TRY -- Return if there is no error information to log. The transaction cannot execute any Transact-SQL statements that would generate a write operation or a COMMIT TRANSACTION.
This -- statement will generate a constraint violation error. if object_id(‘tempdb..#tres’) is not null drop TABLE #tres go CREATE TABLE #tres( ID INT PRIMARY KEY); go BEGIN print ‘First’ BEGIN TRY INSERT #tres(ID) VALUES(1); — Force error 2627, Violation of In theory, these values should coincide. That provides a lot more information and typically is required for resolving errors in a production system. Sql Server Error Code

That's basically all you need to do to create a stored procedure that contains a TRY…CATCH block. Retrieving Error Information in Transact-SQL There are two ways to obtain error information in Transact-SQL:Within the scope of the CATCH block of a TRY…CATCH construct, you can use the following system Stephen Dyckes says: December 19, 2008 at 12:07 pm Thanks for a great reminder about my lack of error handling.

Harinath Thank you Thank you for providing error handling sql server 2012 Surendra Thank you Good Article Jose Antonio Very good Very good explained. EXEC usp_RethrowError; END CATCH; GO -- In the following batch, an error occurs inside -- usp_GenerateError that invokes the CATCH block in -- usp_GenerateError. The procedure, UpdateSales, modifies the value in the SalesLastYear column in the LastYearSales table for a specified salesperson. I want division to throw the error because it's the flag that something is wrong.
uspPrintErrorshould be executed in the scope of a CATCH block; otherwise, the procedure returns without printing any error information. Or someone cloaned my code (that never happens, right?) and did not think about the warnings?
