Dear Lavanya,
You cannot equate the NULL with the operators like = and !=
NULLs can be equated with "IS NULL" or "IS NOT NULL"
(Double quotes " not included)
In u r query if u say IS NOT NULL, then also as per question asked in the very beginning it will not suffice.
As there are multiple columns with multiple NULLs in all the given columns .
Regards
J
