yes and no ... the ANSI/ISO SQL standard offers the three operators you
need:
"IS TRUE", "IS FALSE", and "IS UNKNOWN".
But as far as I know, no vendor has implemented these.
Note the power of these operators; they accept a Boolean argument.
Yes! Very nice. Thanks a lot, will look forward to when
Oracle supports these.
