Hi, I´ve got some tables with column names in lowercase. Before updatering these tables I want to add a trigger that can convert these lowercase to uppercase, and when the tables are updates convert them back to lowercase.. I´ve looked at several examples without any luck. Could someone put me in the direct direction?
