Difference Between @@error And Raiserror In Sql Server
Contents |
Pandey (manub22)December 30, 20136 0 0 0 The new THROW keyword introduced in SQL server 2012 is an improvement over the existing RAISERROR() difference between raiserror and throw in sql server statement.Yes, it’s single ‘E’ in RAISERROR. Both RAISERROR & THROW can be raiserror in sql server 2012 used in T-SQL code/script to raise and throw error within a TRY-CATCH block. Check my previous post for
Raiserror In Sql Server 2005 Example
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()
Raiserror In Sql Server 2008 With Example
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 in sql server 2008 stored procedure
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() wi
the keyword ‘UNION'. » SQL SERVER 2012 - Differences between RAISERROR and THROW withexamples May 27, 2013 by Muhammad Imran A few months ago, I wrote an article about THROW a new technique to raise an exception and transfer execution to a
Raiserror Sql Server 2000
CATCH block shipped with SQL Server 2012. I also compared throw with Raiserror in that article partially. Later sql server raiserror severity on I found a lot of differences and found that THROW is much better than RAISERROR. Let me create a sample error message to sql server raiserror stop execution demonstrate the difference. EXEC sys.sp_addmessage @msgnum = 80000 ,@severity = 10 ,@msgtext = N'This is a test message.' ,@lang = 'us_english'; GO Let me explain the differences: No RAISERROR THROW
1 If you pass any message_id to RAISERROR, the https://blogs.msdn.microsoft.com/manub22/2013/12/30/new-throw-statement-in-sql-server-2012-vs-raiserror/ message_id must be available in sys.messages. Example : RAISERROR (51000, -- Message id. 10, -- Severity, 1, -- State, N'This is a test message'); -OUTPUT Msg 18054, Level 16, State 1, Line 1 Error 51000, severity 10, state 1 was raised, but no message with that error number was found in sys.messages. If error is larger than 50000, make sure the user-defined message is added using sp_addmessage. If you pass any message_id to THROW, the message_id is not necessary to be https://raresql.com/2013/05/27/sql-server-2012-differences-between-raiserror-and-throw-with-examples/ available in sys.messages. Example : THROW 51000 , 'This is a test message' , 1 ; -OUTPUT Msg 51000, Level 16, State 1, Line 1 This is a test message 2 If you pass any message_id to RAISERROR, the message_id range must be between 13000 and 2147483647 and it cannot be 50000. Example : RAISERROR (49913, -- Message id. 10, -- Severity, 1, -- State, N'This is a test message'); -OUTPUT The server could not load DCOM. Software Usage Metrics cannot be started without DCOM. If you pass any message_id to THROW, the message_id range must be between 50000 and 2147483647. Example : THROW 49913 , N'This is a test message' , 1 ; -OUTPUT Msg 35100, Level 16 State 10, Line 1 Error number 49913 in the THROW statement is outside the valid range. Specify an error number in the valid range of 50000 to 2147483647. 3 If you pass any existing message_id to RAISERROR, it will act upon the same Severity level. Example : RAISERROR (80000, -- Message id. 10, -- Severity, 1, -- State, N'This is a test message'); -OUTPUT This is a test message. If you pass any message_id to THROW, whatever the Severity level is, it will always show Severity level 16. Example : THROW 80000 , N'This is a test message' , 1 ; -OUTPUT Msg 80000, Level 16 State 16, Line 1 This is a test message 4 If you use RAISERRORfrom Sql Server 2005, where as the journey of THROW statement has just began with Sql Server 2012. obviously, Microsoft suggesting us to start using THROW statement http://reachsatish.blogspot.com/2013/08/differences-between-raiserror-and-throw.html instead of RAISERROR. THROW statement seems to be simple and easy to use than RAISERROR. Below table lists-out 10 major difference between RAISERROR and THROW with examples: RAISERROR THROW Version of the Sql https://www.sswug.org/basitaalishanmasood-al-farooq/sql-server/handling-errors-in-t-sql-code/ Server in which it is introduced? Introduced in SQL SERVER 2005. And as per BOL, Microsoft is suggesting to start using THROW statement instead of RAISERROR in New Applications. Introduced in SQL SERVER sql server 2012.THROW statement seems to be simple and easy to use than RAISERROR. SYNTAX RAISERROR ( { msg_id | msg_str | @local_variable } { ,severity ,state } [ ,argument [ ,...n ] ] ) [ WITH option [ ,...n ] ] THROW [ { error_number | @local_variable }, { message | @local_variable }, { state | @local_variable } ] [ ; ] Can re-throw the original exception that in sql server invoked the CATCH block? NO. It always generates new exception and results in the loss of the original exception details. Below example demonstrates this: BEGIN TRY DECLARE @result INT --Generate divide-by-zero error SET @result = 55/0 END TRY BEGIN CATCH --Get the details of the error --that invoked the CATCH block DECLARE @ErMessage NVARCHAR(2048), @ErSeverity INT, @ErState INT SELECT @ErMessage = ERROR_MESSAGE(), @ErSeverity = ERROR_SEVERITY(), @ErState = ERROR_STATE() RAISERROR (@ErMessage, @ErSeverity, @ErState ) END CATCH RESULT: Msg 50000, Level 16, State 1, Line 19 Divide by zero error encountered. NOTE:The actual line number of the code which generated Divided By Zero error here is 4, but the exception message returned by RAISERROR is showiung it as 19. Also the error number corresponding to divide by zero error is 8134 in the SYS.Messages table, but the one returned by RAISERROR is 50000. YES. To Re-THROW the original exception caught in the TRY Block, we can just specify the THROW statement without any parameters in the CATCH block. Below example demonstrates this: BEGIN TRY DECLARE @result INT --Generate divide-by-zero error SET @result = 55/0 END TRY BEGIN CATCH THROW END CATCH RESULT: Msg 8134, Level 16, Stat

Like other programming languages, Transact-SQL provides a sophisticated mechanism that captures and handles errors during execution. The mechanism for handling errors during execution includes the Transact-SQL tradition error handling function @@ERROR and object-oriented-programming-style TRY…CATCH construct. In this article, you’ll examine both techniques.Traditional error handlingEarlier versions of SQL Server supported only one way to handle errors—checking the value of @@ERROR after each statement. The @@ERROR function returns the error number if the previous Transact-SQL statement enc
