Sql Trigger Try Catch
From there I want it to see if those numbers entered have already passed or not. If they have passed, cause an error to pass and stop the transaction. Otherwise, I want it to continue on and insert new information into the table. I know I am close on getting this to work, but I cant seem to get the RAISERROR to fire. I am sure it has to do with the fact I am pretty new at this and sql server instead of update trigger I am missing some small detail. Currently I am taking the two months in as variables and the making a third variable to use to turn the other two into a proper datetime format. Then I use the datediff function to try and see if it has passed that way. To no avail though. I keep getting the insert function going, even if the card date is old. USE AdventureWorks2012 GO CREATE TRIGGER BadCreditCardDate ON Sales.CreditCard INSTEAD OF INSERT AS Begin DECLARE @ExpMonth tinyint, @ExpYear smallint, @ExpMonthYear datetime SELECT @ExpMonth=ExpMonth, @ExpYear=ExpYear, @ExpMonthYear = @ExpYear + '-' + @ExpMonth + '-00' FROM INSERTED IF DATEDIFF(MONTH,@ExpMonthYear,GETDATE()) < 0 BEGIN RAISERROR ('The Credit Card you have entered has expired.' ,10,1) ROLLBACK TRANSACTION END ELSE Begin INSERT INTO CreditCard (CardType, CardNumber, ExpMonth, ExpYear, ModifiedDate) Select CardType, CardNumber, ExpMonth, ExpYear, ModifiedDate FROM inserted END End sql-server triggers datediff raiserror share|improve this question asked Jan 25 '15 at 18:52 MikeyZ 256 2 Your trigger has MAJOR flaw in that you seem to assume it'll be called once per row - that is not the case. The trigger will fire once per statement, so if your UPDATE statements affects 25 rows, you'll get the trigger fired once, but then Inserted and Deleted will each contain 25 rows. Which of those 25 rows will your code select here?? SELECT @ExpMonth = ExpMonth FROM Inserted - it's non-deterministic. You need to rewrite your trigger to take

Thanks. sql sql-server-2005 share|improve this question asked Nov 6 '09 at 16:50 Jordan 6491529 add a comment| 1 Answer 1 active oldest votes up vote 3 down vote accepted No, you have to rollback transaction by calling ROLLBACK TRAN: CREATE TRIGGER trg_au_table ON dbo.table AFTER UPDATE AS BEGIN ROLLBACK TRAN END GO http://stackoverflow.com/questions/1688866/raising-errors-in-after-triggers-sql-server-2005 This example will prevent from updating any record. This: CREATE TRIGGER trg_au_table ON dbo.table AFTER UPDATE AS BEGIN RAISERROR('This is a test', 16, 1) END GO will only raise the error but the change will be made in the table. share|improve this answer answered Nov 6 '09 at 17:04 Lukasz Lysik 7,18813661 So, is there an implicit transaction? If I have not begun a transaction explicitly, will ROLLBACK TRAN cause any issues? Thanks! –Jordan Nov 6 '09 at 18:50 Yes, there is an implicit transaction. Update and trigger are closed in one transaction. Trigger is always in one transaction with DML or DDL statement. If you perform an UPDATE you have to wait until the statements in the trigger are finished. RAISERROR does not rollback transaction. –Lukasz Lysik Nov 6 '09 at 19:23 Noting that any rollback statement (without listing a savepoint) will rollback all existing open transactions.

Problem Definition Triggers are strange objects that have their own rules! First rule says that triggers are part of the invoking transaction (the transaction that fired them). Yes, this is raise error sql True and it means that at the beginning of the trigger, both values of @@trancount and xact_state() are "1". So, if we use COMMIT or ROLLBACK inside thetrigger, their values will change to "0" just after executing these statements. Second strange rule is that if the transaction ended in the trigger, the database raises an abortion error. An example for this rule is executing COMMIT or ROLLBACK within the trigger. Next code shows these rules: -- create test table IF OBJECT_ID('dbo.Test', 'U') IS NOT NULL DROP TABLE dbo.Test ; GO CREATE TABLE dbo.Test ( Id INT IDENTITY PRIMARY KEY, NAME NVARCHAR(128) ) ; GO -- create test trigger CREATE TRIGGER dbo.TriggerForTest ON dbo.Test AFTER INSERT AS BEGIN SET NOCOUNT ON; -- declare variables DECLARE @trancount CHAR(1) , @XACT_STATE CHAR(1) ; -- fetch and print values at the beginning of the trigger SET @trancount = @@TRANCOUNT ; SET @XACT_STATE = XACT_STATE() ; PRINT '------------------------------------------------------------------------' ; PRINT 'When trigger starts @@trancount value is (' + @trancount + ' ).'; PRINT 'When trigger starts XACT_STATE() return value is (' + @XACT_STATE + ' ).'; PRINT '------------------------------------------------------------------------' ; -- ending the transaction inside the trigger COMMIT TRAN ; -- fetch
