We are now running SQL Server 2005, which offers more T-SQL features. After just about every SELECT, INSERT, UPDATE, and DELETE, the @@ROWCOUNT and @@ERROR get captured into local variables and http://stackoverflow.com/questions/725891/what-is-the-best-practice-use-of-sql-server-t-sql-error-handling evaluated for problems. If there is a problem the following is done: error message output parameter is set rollback (if necessary) is done info is written (INSERT) to log table return with a error number, unique to this procedure (positive if fatal, negative is warning) They all don't check the rows (only when it is known) and some differ with more or less log/debug info. Also, the rows logic is somethimes split from the error logic (on updates where a concurrency field is checked in the WHERE clause, rows=0 means someone else has updated the data). However, here is a fairly generic example: SELECT, INSERT, UPDATE, or DELETE SELECT @Error=@@ERROR, @Rows=@@ROWCOUNT IF @Rows!=1 OR @Error!=0 BEGIN SET @ErrorMsg='ERROR 20, ' + ISNULL(OBJECT_NAME(@@PROCID), 'unknown') + ' - unable to ???????? the ????.' IF @@TRANCOUNT >0 BEGIN ROLLBACK END SET @LogInfo=ISNULL(@LogInfo,'')+'; '+ISNULL(@ErrorMsg,'')+ + ' @YYYYY=' +dbo.FormatString(@YYYYY) +', @XXXXX=' +dbo.FormatString(@XXXXX) +', Error=' +dbo.FormatString(@Error) +', Rows=' +dbo.FormatString(@Rows) INSERT INTO MyLogTable (...,Message) VALUES (....,@LogInfo) RETURN 20 END I am looking into replacing how we do this with the TRY-CATCH T-SQL. I've read about the TRY...CATCH (Transact-SQL) syntax, so don't just post some summary of that. I'm looking for a
| Tags: Stored Procedures, SQL Server 2005, Transactions, SQL Server 2008 Features, Error Handling This article covers the basics of TRY CATCH error handling in T-SQL introduced in SQL Server 2005. It includes http://www.sqlteam.com/article/handling-sql-server-errors the usage of common functions to return information about the error and using the TRY CATCH block in stored procedures and transactions. SQL Server uses the following syntax to capture errors in Transact-SQL statements: BEGIN TRY http://www.codeproject.com/Articles/38211/Exception-Handling-in-SQL-Server SELECT [First] = 1 SELECT [Second] = 1/0 SELECT [Third] = 3 END TRY BEGIN CATCH PRINT 'An error occurred' END CATCH This returns the following output: First ----------- 1 (1 row(s) affected) Second ----------- (0 row(s) sql server affected) An error occurred A key difference from SQL Server 2000 is that execution is halted when SQL Server encounters an error. At that point execution transfers to the CATCH block. This error isn't returned to the client application or calling program. The TRY CATCH block consumes the error. Error Functions Inside the CATCH block there are a number of specialized functions to return information about the error. BEGIN TRY SELECT [Second] = in sql server 1/0 END TRY BEGIN CATCH SELECT [Error_Line] = ERROR_LINE(), [Error_Number] = ERROR_NUMBER(), [Error_Severity] = ERROR_SEVERITY(), [Error_State] = ERROR_STATE() SELECT [Error_Message] = ERROR_MESSAGE() END CATCH Second ----------- (0 row(s) affected) Error_Line Error_Number Error_Severity Error_State ----------- ------------ -------------- ----------- 2 8134 16 1 (1 row(s) affected) Error_Message --------------------------------------------------- Divide by zero error encountered. (1 row(s) affected) These are the functions you can use inside a CATCH block. These functions all return NULL if they are called from outside a CATCH block. ERROR_NUMBER. The number of the error that occurred. This is similar to @@ERROR except that it will return the same number for the duration of the CATCH block. ERROR_MESSAGE. The complete text of the error message including any substiture parameters such as object names. ERROR_LINE. This is the line number of the batch or stored procedure where the error occured. ERROR_SEVERITY. This is the severity of the error. The CATCH block only fires for errors with severity 11 or higher. Error severities from 11 to 16 are typically user or code errors. Severity levels from 17 to 25 are usually software or hardware errors where processing may not be able to continue. ERROR_STATE. This is sometimes used by the system to return more information about the error. ERROR_PROCEDURE. If the error was generated inside a stored procedure thi

How to handle the errors effectively in SQL Server? Introduction Handling errors in SQL Server became easy with the number of different ways. SQL Server 2005 has introduced the new option that helps to handle the errors effectively. Sometimes we cannot capture the errors which occurred in the end user. Even if we want to know the errors which occurred in the end user, we need to write the code to send it to us. Itcreates an additional overhead for the server. SQL Server 2005 introduced TRY...CATCH statement which helps us to handle the errors effectively in the back end. This handling of the exceptioncanprovide additional information about the errors. TRY...CATCH The TRY...CATCH statement works the sameas in the programming languages. First it get
