How to fire a trigger without changing table data

[John Smith]

I have tables that I want to fire either an update or insert trigger on.

I could write a script containing a long list of inserts but I'm looking for
something simpler. Would isql work? Any special conditions to get it to
work?

I've tried tricks like 'update x set col = col' or 'update x set col = col +
'' '

All the alternatives seem to have problems. Any ideas?

Try:

update MyTable
set
Col1 = 'x'
where
1 = 2

The script Tom posted works for me: Please expand on what you mean by 'it
doesn't work'.

CREATE TABLE MyTable(Col1 int)
GO

CREATE TRIGGER TR_MyTable
ON MyTable FOR INSERT, UPDATE AS
PRINT 'Trigger fired'
GO

UPDATE MyTable
SET Col1 = 'x'
WHERE 1 = 2
GO

DROP TABLE MyTable
GO

--
Hope this helps.

Thanks for the help. The problem was due to NULL values in some columns.

The trigger was firing but not changing data.
