did not have a lot of options. Solution With SQL Server 2005, new error handling has been introduced with the TRY...CATCH tsql error handling processing. Basically what happens is when an error occurs the processing in the TRY block stops and processing is then picked up in the CATCH block. The following illustrates a simple example of how this https://technet.microsoft.com/en-us/library/ms179296(v=sql.105).aspx is done: Step Code Output 1 CREATE PROCEDURE usp_ExampleProcAS SELECT * FROM NonexistentTable;GO Command(s) completed successfully. 2 EXECUTE usp_ExampleProc Msg 208, Level 16, State 1, Procedure usp_ExampleProc, Line 3Invalid object name 'NonexistentTable'. (Note: Processing Stops) 3 BEGIN TRY EXECUTE usp_ExampleProcEND TRYBEGIN CATCH SELECT ERROR_NUMBER() as ErrorNumber, ERROR_MESSAGE() as ErrorMessage;END CATCH; 208 Invalid object name 'NonexistentTable'. (Note: Processing Continues) 4 BEGIN TRY EXECUTE usp_ExampleProcEND TRYBEGIN CATCHEND CATCH; Command(s) completed https://www.mssqltips.com/sqlservertip/1027/sql-server-2005-try-and-catch-exception-handling/ successfully. (Note: Processing Continues) As you can see from the above code and output that when we create the stored procedure for a non-existent table in Step 1 the procedure creates without a problem. If we run the stored procedure using the code in Step 2, we get an error message that the object does not exist. If we run the stored procedure using the code in Step 3, the error is sent to the CATCH block and an error message is returned. At this point processing can continue without a problem. To further illustrate this in Step 4 the stored procedure is run, the error is caught in the CATCH block, but we are not doing anything to process the error. Normally you would have something happen, but this shows that you don't have to have any code in the CATCH block. The values that can be retrieved from the error are also much more detailed, then what you could get with previous versions of SQL Server. Below is a list of the data that can be retrieved when an error occurs. ERROR_NUMBER() - returns the number of the error. ERROR_SEVERITY() - returns the severity. ERROR_STATE() - returns the error state number. ERROR_PROCEDURE() - returns th
Errors in SQL Server 2012 03 January 2013Handling Errors in SQL Server 2012The error handling of SQL Server has always been somewhat mysterious. Now https://www.simple-talk.com/sql/database-administration/handling-errors-in-sql-server-2012/ at last, the THROW statement has been included in SQL Server 2012 that, http://www.sommarskog.se/error_handling/Part1.html combined with the TRY ... CATCH block, makes error handling far easier. Robert Sheldon explains all. 193 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, sql server 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 in sql server 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 constraint to the LastYearSales table The constraint makes it easy to generate an error when updating the tabl
This part is also available in a Spanish translation by Geovanny Hernandez. Introduction This article is the first in a series of three about error and transaction handling in SQL Server. The aim of this first article is to give you a jumpstart with error handling by showing you a basic pattern which is good for the main bulk of your code. This part is written with the innocent and inexperienced reader in mind, why I am intentionally silent on many details. The purpose here is to tell you how without dwelling much on why. If you take my words for your truth, you may prefer to only read this part and save the other two for a later point in your career. On the other hand, if you question my guidelines, you certainly need to read the other two parts, where I go into much deeper detail exploring the very confusing world of error and transaction handling in SQL Server. Parts Two and Three, as well as the three appendixes, are directed towards readers with a more general programming experience, although necessarily not with SQL Server. This first article is short; Parts Two and Three are considerably longer. Table of Contents Introduction Index of All Error-Handling Articles Why Error Handling?
