T Sql Error_number
vote favorite I have a procedure that gets data from a table and inserts it into a temporary table. Then the procedure validates one by one in a while loop. For example: I have 50 rows and the first row fails. In that case, I wish that the procedure continues processing the remaining 49 rows. I'm forcing an error in an insert statement and and I put under it error handling in sql server 2012 @@error <> 0 but does not enter if block. But procedure ends and doesn't continues with the next statement to be executed. I am running the procedure from Query Analyzer and put message with print 'line 1' etc etc. Thank you for your help. This is a similar example create procedure procx as declare @ind_max int, @ind int, @var_id int, @var_name varchar(3) declare @table_x table ( row_id int identity(1,1), id_x int, name_x varchar(25), status_x int ) insert into @table_x values(1, 'xxx', 0) insert into @table_x values(2, 'yyy', 0) insert into @table_x values(3, 'zzz', 0) set @ind_max = 3 set @ind = 1 while (@ind <= @ind_max) begin print 'line 1' select @var_id = id_x , @var_name = name_x from @table_x where row_id = @ind -- Forced error id_x is int field -- Doesn't show line2, line3 ... -- Msg 245, Level 16, State 1, Procedure procx, Line 160 -- Syntax error converting the varchar value 'A' to a column of data type int. insert into test ( id_x , name_x ) values ( 'A' , @var_name ) if @@error != 0 begin print 'line 2' goto next_row insert into log_test values(@var_id, 'Error') end print 'line 3' update @table_x set status_x = 1 w

Tsql Iserror
vote We have trigger on a table. The trigger implementation is to insert

a record in another table. If any error occurred in the trigger then the trigger should log the error to a set xact_abort file on the file system. CREATE TRIGGER [myTRIGGER] ON [dbo].[MyTest] AFTER INSERT AS declare @errorcode int; INSERT INTO MySecondTable (id, myvalue) values (null, 'hey') set @errorcode=@@ERROR if (@errorcode <>0) print 'Error occurred with error http://stackoverflow.com/questions/19551176/exception-handling-in-sql-server-2000 code "' + CONVERT(varchar, @@ERROR) + '"' Problem If the insert statement fails, for example because of a null violation, then trigger aborts and never reaches the next step in the trigger T-SQL code. IS this a limitation or there's somthing wrong on the above code?

However, the problem is that a CONSTRAINT failure (NULL violation) occurs BEFORE data is inserted into the table. As a result, the TRIGGER is never fired. The only way to have a TRIGGER 'catch' CONSTRAINT failures is to use a BEFORE TRIGGER.

Actually i'm trying to insert a record in another table "MySecondTable" from the context of a trigger on another table "MyTest". The problem is that when a null violation occures while inserting a record into "MySecondTable", I was not able to catch that exception from the calling trigger, as if the control doesn't return back to the trigger. Wednesday, October 24, 2007 8:21 PM Reply | Quote 0 Sign in to vote You cannot catch most errors using Try/catch or @@Error. It will simply terminate and roll back. You can do NOTHING about it.In your case, if the "INSERT INTO MySecondTable (id, myvalue) values (null, 'hey')" fails for any reason, you will NEVER get to "set @errorcode=@@ERROR". The code simply EXITS at the INSERT. As I have sai
facebook google twitter rss Exception Handling in SQL Server 2000 and 2005 Posted on May 24, 2006 by JagadishChaterjee This article mainly discusses and compares the features of exception handling in Microsoft SQL Server 2000 with the same features https://www.aspfree.com/c/a/ms-sql-server/exception-handling-in-sql-server-2000-and-2005/ in SQL Server 2005.Basically, in Microsoft SQL Server 2000, there exists no structured exception handling. We need to dependon @@ERROR for any errors that occur.Microsoft SQL Server 2005 has beenenhanced in such a way that developers http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=96763 program more powerful and error resistant SQL codewithstructured exception handling. In this article, I shall provide some samples in both SQL Server 2000 and SQL Server 2005. I shall also give explanations on both sql error of the approaches by comparing each of them. I've tried to keep thisarticle looks as simple as possible to get beginners off to a good start. I am assuming that the readers of this article will have some knowledge of RDBMS along with some exposure to SQL Server 2000. Introduction to error handling Before going to exception handling, let us first determineall the possible ways sql error handling to get errors. Errors may occur in T-SQL (of course not only in T-SQL) in several possible ways, including hardware failures, network failures, bugs in programs, out of memory and for several other reasons. We may not know which error has been raised at what moment. But we need to handle all such errors and provide some meaningful messages to the user (instead of making the user horrified with error messages that are impossible to understand). An exception is generally a runtime error which gets raised by SQL Server runtime when a T-SQL block is in the process of execution. Handling the exception is something like trapping the error (or exception) and inserting that error into the error_log table including date, error message, and other details. Storing error messages in the error_log table makes it easy to trace for future maintenance. It doesn’t mean that errors are in the table only for maintenance; we can take certain actions (programmatically) when an error occurs. Error handling is a very monotonous task and we should make it as simple as possible. Iferror handling is too complex, bugs might creep into the error handling and should be tested after each statement. Another special case is the use of transactions. We need to issue

I have set the volatile @@ERROR global to a variable, but the proc is still throwing a primary key exception; hence, it's not being trapped. My question is why isn't my exception being handled?Here's my code, your help is much obliged.
