Sql Server Throw Vs Raiserror
RAISERROR & THROW can be used in T-SQL code/script to raise and throw sql server raiserror example error within a TRY-CATCH block. Check my previous post for TRY-CATCH block, [link]. >> With RAISERROR developers had to use incorrect syntax near throw 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)
Raiserror In Sql Server 2012 Example
,@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 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

Isn't the THROW procedure a sytem procedure? Why can't it find it? Furthhermore, what is the difference between unsing THROW and ErrorState ? Is one older/newer/better than the other?

If you're using 2008R2, then it didn't exist.

SQL � @@ERROR VS RAISERROR @@ERROR VS RAISERROR Navas Khan | 6:27 PM | 0 comments Difference between @@error and Raiserror in sql What is @@ERROR? The system function @@ERROR returns an error code if an error was encountered after the completion of the TSQL statement immediately preceding it, otherwise it will return 0, means success. The value of @@ERROR changes for each TSQL statement and the only way to keep track of errors is by using a temporary variable to store the error code. If there is no need to keep track of the error but simply act upon it, then the value of @@ERROR can be checked after the TSQL statement to be tested. Syntax: CREATE PROCEDURE spDivision @FirstNumber int, @SecondNumber int AS DECLARE @errnum int Select @FirstNumber/@SecondNumber SET @errnum=@@Error IF @errnum<>0 SELECT ‘Error' EXEC spDivision1 5,0 Msg 8134, Level 16, State 1, Procedure spDivision, Line 4 Divide by zero error encountered. (1 row(s) affected) The return code is changed automatically to store the latest @@Error value if no RETURN statement is present. Even if there are more statements after the error occurred, the error code is still preserved. What is RAISERROR? RAISERROR raise an error with a user defined error message. The error message is either created dynamically or stored in the system table sysmessages. Syntax: CREATE PROCEDURE SPDivision @FirstNumber int, @SecondNumber int AS IF @SecondNumber=0 BEGIN SELECT ‘Error' RAISERROR (‘Error: Division by zero.', 16, 1) END ELSE select @FirstNumber/@SecondNumber When Run SP as EXEC SPDivision 5, 0 will show error as (1 row(s) affected) Msg 50000, Level 16, State 1, Procedure spDivision, Line 6 Error: Division by zero. If the error message is used in many SP's, to avoid inconsistencies due to changes in the message, the message can be stored in sysmessa
