Umm, ZSQL just passes SQL to your database; there is no ZSQL language.

So -> use the SQL your database would use.

In some databases (notably MS Access), you can use a wildcharacter in
a date as you are; in most databases, you would use a date-specific
operator. (It's also _much_ faster as it can use indexes, etc.)

In PostgreSQL, for instance, if you want to find everyone who did
something between Oct 1, 2001 and Oct 31, 2001, you'd say:

SELECT * FROM TABLE WHERE start_date BETWEEN '10/1/2001' AND
'10/31/2001';

Sytax will vary a bit from DB to DB, but this is usually the best way.
