Error running query when field value is NULL

I am having trouble running a query on a table if one of my selected fields 
contains a NULL value.
Example:

    Select * from ItemNonInventory

If any of the fields in that table contain a null value I get an E_FAIL 
error.

Anyone got an idea as to why this happens?

One other question I have is, Is it possible to write a query that looks for 
anyfield that contains null?
This way I can query only records with valid data.

Thanks
