Re: For each statement trigger and update table - Mailing list pgsql-sql

Oh, so you're defining transition relations (REFERENCING NEW TABLE, OLD TABLE ) as in here?

CREATE TRIGGER paired_items_update   AFTER UPDATE ON paired_items   REFERENCING NEW TABLE AS newtab OLD TABLE AS oldtab   FOR EACH ROW   EXECUTE FUNCTION check_matching_pairs();

According to the docs, not possible to use a transition table and column list together

please do so, along with your trigger definition. Are you aware that you can define your update trigger to fire on a specific column?

https://www.postgresql.org/docs/current/sql-createtrigger.html  

For UPDATE events, it is possible to specify a list of columns using this syntax:

UPDATE OF column_name1 [, column_name2 ... ]

Not sure if this is possible

Basically I want to have a trigger which updates an array column in the same table when a column is updated

This works as a row level trigger, but not as per statement

I have hit the recursive issue (where update fires update trigger which fires etc)

According to the docs I cannot use columns and relative tables together

So any suggestions? I can give code when I get home, but it's pretty simple stuff
