Hello listers,

 

We have ‘table a’ which has defined to it an ‘after insert or update’ trigger function

That inserts to ‘table b’, obviously for every update or insert of table a.  The challenge

I have now is to update a new date column on ‘table a’ with a value coming out of

Another inhouse written function within the trigger function.  But I cannot use the UPDATE

statement within the update trigger function for fear of an infinite loop. 

All I need to do is to populate the date field of the row that is currently being processed by the trigger function. 

Is there a command within plpgsql that can help me with this?

 

This seems like an elementary question, but I am a very elementary user of

Postgres functions.  Thank you for your time,
