Hi Mark

The code below was the code generated by the SQL template which is created
when you add a new trigger.
As you know, when you run the SQL containing "CREATE ...", the trigger
itself containing "ALTER ..." is created.
A trigger for Insert already existed. It is named
[dbo].[T_VariantsTable_ITrig].
That's why I chose the name [dbo].[T_VariantsTable_UTrig] for my Update
trigger.

However, this morning - after my workstation had been closed down for the
weekend - the issue has vanished. So, for some reason, the new trigger
hadn't been saved in full - or what? I really did logout and login again
several times and refreshed "everything". But no reboot. Is that really
needed?

Hello Gustav

I just copied your code into SSMS, change the two table names and it
worked.  It created a trigger on a db here locally on my machine.

The only thing I had to do was change the Alter to a Create.  Would that be
your problem?

If not, the only other thought that comes to mind is the PPT database the
one with the table to hold the trigger.  IOW, does the db and table exist?

Sorry I could not help more,

Mark
