There would hardly be a database developer who hasn’t written triggers in their career. It is fairly common knowledge that you can have more than one trigger of the same type, i.e. INSERT/UPDATE/DELETE on the same table. Therefore, the following is perfectly valid:
USE tempdb GO CREATE TABLE dbo.AppendTriggerTest (RowId INT IDENTITY(1,1), RowValue VARCHAR(50) ) GO CREATE TRIGGER dbo.MainTrigger ON dbo.AppendTriggerTest FOR INSERT AS BEGIN PRINT '<<<< INFO >>>> Main Trigger fired...' END GO CREATE TRIGGER dbo.AppendTrigger ON dbo.AppendTriggerTest FOR INSERT AS BEGIN PRINT '<<<< INFO >>>> Append Trigger fired...' END GO
However, this was not the case in the days of SQL Server 6.5. In order to have a more than one trigger of the same type on the same table, the WITH APPEND clause needs to be used, which is effectively interpreted as AFTER. In the days of SQL Server 6.5, the trigger “AppendTrigger” will need to be defined as:
CREATE TRIGGER dbo.AppendTrigger ON dbo.AppendTriggerTest FOR INSERT WITH APPEND --NOTICE THE WITH APPEND CLAUSE HERE, --DEPRECATED FROM SQL 2012 ONWARDS AS BEGIN PRINT '<<<< INFO >>>> Append Trigger fired...' END GO
Starting SQL Server 2012, the compatibility levels lower than 90 (i.e. SQL Server 2000 and below) are no longer supported. In accordance to this, the WITH APPEND clause has also been deprecated.
I assume that you are not using this in your production code, if you are, please upgrade! There is no workaround/alternate to this.
