Empty columns comparison

324137Dec 19 2006 — edited Dec 20 2006
Hello All,

Is there a kind of a "global setting" in pl/sql that may be changed in order to have Oracle evaluates two empty (null) strings as equal or the only way is to use NVL(<col>,0) = NVL(<col>,0) when comparing two database columns as in ?

SELECT ... FROM a, b WHERE a.col1 = b.col1

Thank you.
