somewhat mysterious. Now at last, the THROW statement has been included in sql server catch error line number SQL Server 2012 that, combined with the TRY ... CATCH block, makes error handling far easier. Robert Sheldon explains sql server try catch finally all. 193 14 Robert Sheldon Since the release of SQL Server 2005, you've been able to handle errors in your T-SQL code by including a TRY…CATCH block that controls the http://stackoverflow.com/questions/1111501/error-and-or-try-catch flow of your script should an error occur, similar to how procedural languages have traditionally handled errors. The TRY…CATCH block makes it easy to return or audit error-related data, as well as take other actions. And within the block-specifically, the CATCH portion-you've been able to include a RAISERROR statement in order to re-throw error-related data to the calling application. However, with the https://www.simple-talk.com/sql/database-administration/handling-errors-in-sql-server-2012/ release of SQL Server 2012, you now have a replacement for RAISERROR, the THROW statement, which makes it easier than ever to capture the error-related data. In this article, we'll look at the TRY…CATCH block used with both the RAISERROR and THROW statements. The examples are based on a table I created in the AdventureWorks2012 sample database, on a local instance of SQL Server 2012. Listing 1 shows the T-SQL script I used to create the LastYearSales table. 123456789101112131415161718 USE AdventureWorks2012;GOIF OBJECT_ID('LastYearSales', 'U') IS NOT NULLDROP TABLE LastYearSales;GOSELECTBusinessEntityID AS SalesPersonID,FirstName + ' ' + LastName AS FullName,SalesLastYearINTOLastYearSalesFROMSales.vSalesPersonWHERESalesLastYear > 0;GO Listing 1: Creating the LastYearSales table The script should be fairly straightforward. I use a SELECT…INTO statement to retrieve data from the Sales.vSalesPerson view and insert it into the newly created table. However, to demonstrate how to handle errors, we need to add one more element to our table: a check constraint that ensures the SalesLastYear value is never less than zero. Listing 2 shows the ALTERTABLE statement I used to add the constraint. 123 ALTER TABLE LastYearSalesADD CONSTRAINT ckSalesTotal CHECK (SalesLastYear >= 0);GO Listi
Pandey (manub22)December 30, 20136 0 0 0 The new THROW keyword introduced in SQL server 2012 is an improvement over the existing RAISERROR() statement.Yes, it’s single ‘E’ in RAISERROR. Both RAISERROR & THROW https://blogs.msdn.microsoft.com/manub22/2013/12/30/new-throw-statement-in-sql-server-2012-vs-raiserror/ can be used in T-SQL code/script to raise and throw error within a TRY-CATCH block. Check my previous post for TRY-CATCH block, [link]. >> With RAISERROR developers had to use different ERROR_xxxx() system functions to get the error details to pass through the RAISERROR() statement, like:- ERROR_NUMBER()- ERROR_MESSAGE()- ERROR_SEVERITY()- ERROR_STATE() let’s see an example: -- Using RAISERROR()
DECLARE
@ERR_MSG AS NVARCHAR(4000)
,@ERR_SEV AS SMALLINT
,@ERR_STA AS SMALLINT
BEGIN TRY
SELECT 1/0 as DivideByZero
END TRY
BEGIN CATCH
SELECT @ERR_MSG = ERROR_MESSAGE(),
@ERR_SEV =ERROR_SEVERITY(),
@ERR_STA = ERROR_STATE()
SET @ERR_MSG= 'Error occurred while retrieving the data from database: ' + @ERR_MSG
RAISERROR (@ERR_MSG, @ERR_SEV, @ERR_STA) WITH NOWAIT
END CATCH
GO Output:(0 row(s) affected)Msg 50000, Level 16, State 1, Line 15Error occurred while retrieving the data from database: Divide by zero error sql server try encountered. The RAISERROR() can take first argument as message_id also instead of the message. But if you want to pass the message_id then it has to be in sys.messages >>With THROW the benefit is: it is not mandatory to pass any parameter to raise an exception.Just using the THROW; statement will get the error details and raise it, as shown below: -- Using THROW - 1
BEGIN TRY
SELECT 1/0 as DivideByZero
END TRY
BEGIN CATCH
THROW;
END CATCH
GO Output:(0 row(s) affected)Msg 8134, Level 16, State 1, Line 2Divide by zero error encountered. As you see in the Output above, the error message thrown is the default one. But you can also add your customized message, we will see below. IMP NOTE:Default THROWstatement will show the exact line where the exception was occurred, here the line number is 2 (highlighted GREEN above). But RAISERROR() will show the line number where the RAISERROR statement was executed i.e. Line 15 (highlighted YELLOW above)and not the actual exception. Also passing the message_id won’t require it to be stored in sys.messages, let’s check this: -- Using THROW - 2
DECLARE
@ERR_MSG AS NVARCHAR(4000)
,@ERR_STA AS SMALLINT
BEGIN TRY
SELECT 1/0 as DivideByZero
