  • 0

I am quite new to writing SQL triggers and I had one working for a while now as desired however now I would like to add a where clause to the trigger so that it only fires if a certain condition is met.

In this particular scenario I want to check and see if ContextDN like '%FA 2012%' and if so then have the trigger fire. Here is my current trigger:

CREATE TRIGGER [dbo].[setAsMoodle]
ON [dbo].[LMS_Section]
For Insert
As
INSERT INTO [dbo].[CUS_LmsSection_LmsProxy] (LMSSectionID, LMSProxyID, LMSSectionCtxDN)
select  SectionID , 'DEE76E47-25E6-459B-9D38-1BCAFA44077A', ContextDN from inserted

Any suggestions on how to go about doing this?

    Just put the where on the end of your insert statement

    USE ICS_NET; 

GO 
CREATE TRIGGER [dbo].[setAsMoodle] 
ON [dbo].[LMS_Section] 
For Insert 
As 
INSERT INTO [dbo].[CUS_LmsSection_LmsProxy] (LMSSectionID, LMSProxyID, LMSSectionCtxDN) 
select  SectionID , 'DEE76E47-25E6-459B-9D38-1BCAFA44077A', ContextDN from inserted
where ContextDN like '%FA 2012%'

    The trigger will always fire, but only the rows matching the condition get inserted.

    This is important as the trigger may fire for multiple rows at once for a batch insert so you wouldn’t be able to selectively run it.
