You could write a rule for each table/column that would substitute
NULL for ''.
However, the concept is all wrong. NULL means "I don't know what
this value is". '' means "I know that this value is an empty string".
Furthermore, having NULLs in columns means you have to be careful
to use ternary logic for every condition (because NULL=x is neither
true nor false).
