I know more or less what is the syntax of a trigger statement(at least in theory, since I have never made use of a trigger in an app).
My question is if a trigger can cover the situation below:
Set a column value to null if the corresponding value that comes from a submitted a form is an empty string.
Can the above be achieve with a trigger?
