Transact-SQL Syntax ConventionsSyntax Copy -- Syntax for SQL Server, Azure SQL Database, Azure SQL Data Warehouse, Parallel Data Warehouse THROW [ { error_number | @local_variable }, { message | @local_variable }, { state | @local_variable } ] [ ; ] Argumentserror_number Is a constant or variable that represents the exception. error_number is int and must be greater than or equal to 50000 and less than or equal to 2147483647.message Is an string or variable that describes the exception. message is nvarchar(2048).state Is a constant or variable between 0 and 255 that indicates the state to associate with the message. state is tinyint.RemarksThe statement before the THROW statement must be followed by the semicolon (;) statement terminator.If a TRY…CATCH construct is not available, the session is ended. The line number and procedure where the exception is raised are set. The severity is set to 16.If the THROW statement is specified without parameters, it must appear inside a CATCH block. This causes the caught

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 https://msdn.microsoft.com/en-us/library/ee677615.aspx 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

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

The journey of RAISERROR started from Sql Server 7.0, where as the journey of THROW statement has just began with Sql Server 2012. obviously, Microsoft suggesting us to start sql server using THROW statement instead of RAISERROR. THROW 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. Part I: Exception Handling Basics - MUST Read Article Part II: TRY…CATCH (Introduced in Sql Server 2005) Part III: sql server throw RAISERROR Vs THROW (Throw: Introduced in Sql Server 2012) Part IV: Exception Handling Template Raiserror Vs Throw Below table lists-out 10 major difference between RAISERROR and THROW with examples: RAISERROR THROW Version of the Sql Server in which it is introduced? 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 INError Handling 28 October 2010Defensive Error HandlingTRY...CATCH error handling in SQL Server has certain limitations and inconsistencies that will trap the unwary developer, used to the more feature-rich error handling of client-side languages such as C# and Java. In this article, abstracted from his excellent new book, Defensive Database Programming with SQL Server, Alex Kuznetsov offers a simple, robust approach to checking and handling errors in SQL Server, with client-side error handling used to enforce what is done on the server. 39 1 Alex Kuznetsov The ability to handle errors is essential in any programming language and, naturally, we have to implement safe error handling in our T-SQL if we want to build solid SQL Server code. SQL Server 2005, and later, superseded the old style @@Error error handling, with the TRY…CATCH blocks that are more familiar to Java and C# programmers. While use of TRY…CATCH certainly is the best way to handle errors in T-SQL, it is not without difficulties. Error handling in T-SQL can be very complex, and its behavior can sometimes seem erratic and inconsistent. Furthermore, error handling in Transact SQL lacks many features that developers who use languages such as Java and C# take for granted. For example, in SQL Server 2005 and 2008, we cannot even re-throw an error without changing its error code. This complicates handling errors, because we have to write separate conditions for detecting exceptions caught for the first time, and for detecting re-thrown exceptions. This article will demonstrate simple SQL Server error handling, using XACT_ABORT and transactions, describe the most common problems with TRY…CATCH error handling, and advocate that the defensive programmer, where possible, implements only simple error checking and handling in SQL Server, with client-side error handling used to enforce what is done on the server. Prepare for Unanticipated Failure Any statement can, and at some point inevitably will, fail. This may seem to be a statement of the obvious, but too many programme
