Robert,
Thanks for the extra tips and links. I see you are a fan of Tom Kyte. I am too. I have learnt a lot from him, and still learning...

Cheers!

You can also use DECODE, which (as an exception to the normal rule) will say that NULL = NULL

DECODE(COMM, NULL, 'SAL', 'SAL & COMM')

But, keep in mind that NVL and NVL2 seem to have a performance hit over the more verbose manual NULL check.

Cheers,
Robert
