NULL and empty ('') are different. When you query, SELECT * FROM tablename
WHERE deptno is NULL, it shows the NULL values. From the output you listed,
there aren't any NULL values. They are empty ones. So you can delete them by
doing DELETE FROM tablename WHERE deptno = '' AND dname ='' AND location =

Also, you can check the length of the column (LEN)
