I have a table usage, I would like to create a (function or procedure) called by the trigger to increment column counter after an update.
Can someone lend me a hand with the process behind creating this function,procedure and trigger.
Table "public.usage"
Column | Type | Modifiers
---------------+-----------------------+-----------
instrument | character varying(13) |
date | date |
counter | integer |
