RAISERROR can either reference a user-defined message stored in the sys.messages catalog view or build a message dynamically. The message is returned as a server error message to the calling application or to an associated CATCH block of a TRY…CATCH construct. New applications should use THROW instead.

RAISERROR on its own continues reading through the stored procedure as it will then bring up another error. –Curt Jul 15 '10 at 14:12 +1, however, I'd make it RETURN n where n is an integer. I make negative return values warning messages (invalid user input, etc) and positive return values fatal errors (insert failure, etc). The calling application can determine how to handle the message (hard stop and/or just display the message) based on the return value being positive/negative. –KM.

The journey of RAISERROR started from Sql https://www.simple-talk.com/sql/database-administration/handling-errors-in-sql-server-2012/ Server 7.0, where as the journey of THROW statement has just began with Sql Server 2012. obviously, Microsoft suggesting us to start using THROW statement instead of RAISERROR. THROW statement seems to be simple and easy sql server 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: RAISERROR Vs THROW (Throw: Introduced in Sql Server 2012) Part IV: Exception Handling Template Raiserror Vs Throw Below table lists-out 10 sql server raiserror 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 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 (@Errors in SQL Server 2012 03 January 2013Handling Errors in SQL Server 2012The error handling of SQL Server has always been somewhat mysterious. Now at last, the THROW statement has been included in SQL Server 2012 that, combined with the TRY ... CATCH block, makes error handling far easier. Robert Sheldon explains all. 195 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 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 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 Listing 2: Adding a check co
