Is there any way to know whether a Database column is updated in Postgresql when calling update function in Java in Eclipse? I tried using trigger, but it will only give the number of rows updated. I need to know which column is updated.

  • Well, like I explained in that comment, there is no ready made mechanism to let you know which column was updated. Plenty of workarounds though, such as first loading the row before performing the update, then comparing. Commented Aug 3, 2016 at 9:43
