I´d like to use Upp::SqlCtrls to submit database table field contents for user edition and SqlUpdate the db ONLY if the user changes any of the field values.
What does method Upp::SqlCtrls::IsModified() do?
Is it to point whether a user edited any of the Ctrl contents in a SqlCtrls set?
In other words, how do I check whether a user changed the contents of any of the Ctrls of a given SqlCtrls set?
Do I have to compare one by one with their previous db values upon users´ SqlCtrls submission?
