Marsh, I don't use DDL much, so I'm not sure how to add a CONSTRAINT that
will index the field "Duplicates Ok." Is that a constraint?
Allen,
Well, I was at least partially wrong about this whole issue.
While it's true that leaving out UNIQUE will deal with the
Duplicates OK issue, the NOT NULL option must then be
specified. This does not meet Bob's needs so that's the
reason he needs to use the CREATE INDEX statement.
There are more differences between CONSTRAINT and CREATE
INDEX than I had realized.
Sorry about all the confusion I brought to the thread.
