There are situations where cursors are helpful. Otherwise they would probably not have been introduced. –Andriy M Apr 9 '13 at 5:44 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote Apparently, you've got a RETURN statement immediately after ROLLBACK TRANSACTION. Have you tried just removing it? Although you could also rewrite the body using TRY/CATCH instead, like this: ... WHILE @@FETCH_STATUS = 0 BEGIN BEGIN TRY INSERT INTO STIDENT_A(SID,SNAME,SUB,MARKS) VALUES (@SID,@SNAME,@SUB,@MARKS); END TRY BEGIN CATCH -- this section must have some statement, -- so, why not log the erroneous data to the screen at least? PRINT @SID; PRINT @SNAME; PRINT @SUB; PRINT @MARKS; PRINT ''; -- an empty line as a delimiter -- or, perhaps, into a table? --INSERT INTO SomeFailLog (SID,SNAME,SUB,MARKS) --VALUES (@SID,@SNAME,@SUB,@MARKS); END CATCH; FETCH NEXT FROM LOAD_DATA INTO @SID,@SNAME,@SUB,@MARKS; END; ...

| 2 Comments | Tags: Stored Procedures The following article introduces the basics of handling errors in stored procedures. If you are not familiar with the difference between fatal and http://www.sqlteam.com/article/handling-errors-in-stored-procedures non-fatal errors, the system function @@ERROR, or how to add a custom error with the system stored procedure sp_addmessage, you should find it interesting. The examples presented here are specific to stored procedures as https://www.simple-talk.com/sql/database-administration/handling-errors-in-sql-server-2012/ they are the desired method of interacting with a database. When an error is encountered within a stored procedure, the best you can do (assuming it’s a non-fatal error) is halt the sequential sql server processing of the code and either branch to another code segment in the procedure or return processing to the calling application. Notice that the previous sentence is specific to non-fatal errors. There are two type of errors in SQL Server: fatal and non-fatal. Fatal errors cause a procedure to abort processing and terminate the connection with the client application. Non-fatal errors do not abort processing a procedure or sql server stored affect the connection with the client application. When a non-fatal error occurs within a procedure, processing continues on the line of code that follows the one that caused the error. The following example demonstrates how a fatal error affects a procedure. USE tempdb go CREATE PROCEDURE ps_FatalError_SELECT AS SELECT * FROM NonExistentTable PRINT 'Fatal Error' go EXEC ps_FatalError _SELECT --Results-- Server:Msg 208,Level 16,State 1,Procedure ps_FatalError_SELECT,Line 3 Invalid object name 'NonExistentTable'. The SELECT in the procedure references a table that does not exist, which produces a fatal error. The procedure aborts processing immediately after the error and the PRINT statement is not executed. To demonstrate how a non-fatal error is processed, I need to create the following table. USE tempdb go CREATE TABLE NonFatal ( Column1 int IDENTITY, Column2 int NOT NULL ) This example uses a procedure to INSERT a row into NonFatal, but does not include a value for Column2 (defined as NOT NULL). USE tempdb go CREATE PROCEDURE ps_NonFatal_INSERT @Column2 int =NULL AS INSERT NonFatal VALUES (@Column2) PRINT 'NonFatal' go EXEC ps_NonFatal_INSERT --Results-- Server:Msg 515,Level 16,State 2,Procedure ps_NonFatal_INSERT,Line 4 Cannot insert the value NULL into column 'Column2',table 'tempdb.dbo.NonFatal'; column does not_allow nulls.INSERT fails. The statement has been terminated. NonFatal
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 TAB
