Newbie here.
I'm trying to remove some records from various tables in my database, but have noticed that some tables will allow this, while others won't - as there are no icons to allow this at the start of the row. This is a database (and app) that I've "inherited" from someone else and it was they who set up the database (honest!
). Would this be a setting somewhere in the SQL setup?
If so, is there any danger attached to making them all editable?
TIA.
