If what you're trying to do is test if the value coming back from the database is null before displaying it, you could use

IsNull(tableFieldValue)

before displaying it. To be safe, you could also test for the field's length:

If len(TRIM(tableFieldValue))= 0 or IsNull(tableFieldValue) then...

Hope it helps.
