Thanks Jordon,
That explains it.
I saw that section in the manual but assumed ‘Ignore Trigger’ applied to writes as well.
And yes, I’ve a couple of other ways of getting the result I want; the group would have been convenient.
About the documentation: The manual is very high-level. Is there any in-depth documentation for ignition?
I’m just using SQL Bridge at the moment but will be starting a project in a few weeks that will require a client as well.
It’s the basic stuff that’s catching me:
-Syntax relating to [],[~], [.] etc.
-Definitions of datatypes (int4, int8, etc) as used in ignition
-Realworld examples of Transaction Group use.
My background is SQL, VB, C#, Wonderware, Archestra, Siemens, Rockwell.
I’m getting to like Python, it’s very clean.
Your ‘IIRC’ threw me for a moment 
Thanks for the help, I appreciate it.
