statement seems to be simple and easy to use than RAISERROR. This is the third article in the series of articles on Exception Handling in Sql Server. Below is the complete list of articles in this series.

Introduced in SQL SERVER 7.0. And as per BOL, Microsoft is suggesting to start using THROW statement instead of RAISERROR in New Applications.
RAISERROR can't be used in the Sql Server 2014's Natively compiled Stored Procedures. Introduced in SQL SERVER 2012. THROW statement seems to be simple and easy to use than RAISERROR. THROW statement can be used in the Sql Server 2014's Natively Compiled Stored Procedure. SYNTAX RAISERROR ( { error_number | message | @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 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 thethe keyword ‘UNION'. » SQL SERVER 2012 - Differences between RAISERROR and THROW withexamples May 27, 2013 by Muhammad Imran A few months ago,
Throw Exception In Sql Server Stored Procedure
I wrote an article about THROW a new technique to raise an incorrect syntax near throw exception and transfer execution to a CATCH block shipped with SQL Server 2012. I also compared throw with Raiserror sql server raiserror stop execution in that article partially. Later on I found a lot of differences and found that THROW is much better than RAISERROR. Let me create a sample error message to demonstrate the difference. EXEC http://sqlhints.com/2013/06/30/differences-between-raiserror-and-throw-in-sql-server/ 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 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, https://raresql.com/2013/05/27/sql-server-2012-differences-between-raiserror-and-throw-with-examples/ 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 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 thclient application will respond to Result Sets, and any error messages that are raised by SQL Server with a severity higher than 10. For error messages with a severity of 10 or less, the .NET event SQLConnection.InfoMessasge can be used to return information during query http://www.jimmcleod.net/blog/index.php/2010/07/19/print-vs-raiserror/ processing. In Management Studio, the difference between a Message and and Error is that the Error is flagged in red on the Messages result panel and may trigger rollbacks or break connections, depending on the severity of the error. PRINT One https://dhananjayspeaks.wordpress.com/2012/11/21/difference-between-raiserror-and-throw-in-sql-server/ use of communicating data back to the client is for stored procedures to let the user know where they are up to. While this could be used for production code, it is usually used as a poor man’s debugger. By sql server sprinkling PRINT “Currently at point x” statements through your stored procedure, you can get an inkling of where the processing is up to. However, PRINT has a noticeable drawback – the results are not returned immediately. Instead, anything sent to PRINT will be buffered, and not released until the buffer is full, or the query completes. This buffer is around 8KB in size. “No problem!” I hear you cry. “I’ll just pad my PRINT message out to be 8KB!” Nice try, but difference between raiserror unfortunately, the PRINT statement will trim to varchar(8000) or nvarchar(4000), which isn’t enough. For example: PRINT 'A' + REPLICATE(' ', 8000) PRINT 'B' + REPLICATE(' ', 124) WAITFOR DELAY '00:00:05' PRINT 'C' In this example, we’re using REPLICATE to try to pad out the PRINT’s message, but we need two PRINT statements to get anything back immediately. By running the example, and flicking to the Messages screen in Management Studio, you can see if A is being returned before or after the WAITFOR DELAY statement. In my tests, the 124 on the B line is not a static value – it was 134 for a different server. So, two PRINT messages does not really seem like an acceptable solution. RAISERROR Enter RAISERROR. While the RAISERROR syntax is slightly more complicated, it’s also a lot more powerful (although the misspelling is quite annoying). RAISERROR ('Message', 0, 1, ..., ...) WITH NOWAIT The first parameter is simply a textual description of the error/message. Next (0) is the Severity level. If this value is 10 or less, it will be counted as a Message, and not as an Error. The 1 indicates the State of the message – for a message, you’ll generally keep this at 1. After the State, you can list multiple parameters that will be inserted into the first parameter – more on this shortly. Example 1 shows two methods of RAISERROR, one where the text of the message is stor
Between RAISERROR and THROW in SQLServer November 21, 2012 Dhananjay Kumar Upadhyay Leave a comment Go to comments As we all know that both the RAISERROR and THROW statements are used to raise an error in T-SQL block. However, the quesion arises is if both do the same job, why do we have the two different statements? So, let us take a look at the difference between the two statements. RAISERROR Statement THROW Statement Ancient statement supported by the SQL Server. New statement introduced in the SQL Server 2012. Little complex statement, offers more features. Very simple statement, offers limited features. Message string offers printf style formatting. Message string does not offer printf style foramtting. Can generate user-defined i.e. msg_id > 50000 as well as system-defined i.e. msg_id < 50000 errors. Can only generate user-define i.e. msg_id > 50000 errors. If Message ID is used, it must be defined in sys.messages catalog view. If Message Number is used, it may not be defined in sys.messages catalog view. Different severity level can be defined with this statement. It does not allow to set different severity level. It always has severity level 16. It does not require preceding statement to end with semicolon (;) statement terminator. It requires preceding statement to end with semicolon (;) statement terminator. Hope it helps us out to understand difference between these two statements. Rate this:Share this:TwitterFacebookLinkedInEmailPrintLike this:Like Loading...
