SELECT * FROM CUSTOMERS LEFT JOIN CALLS ON CUSTOMERS.PHONE = CALLS.PHONE AND CALLS.DATE = "02/28/12" WHERE CUSTOMERS.DATE = "02/28/12" But that would only get customers created on 2/28 AND having a call on 2/28 OR not call at all on 2/28. This would give you customers created on 2/28 with no calls AND customers created on 2/28 with a call on 2/28: SELECT * FROM CUSTOMERS LEFT JOIN CALLS ON CUSTOMERS.PHONE = CALLS.PHONE WHERE CUSTOMERS.DATE = "02/28/12" AND (CALLS.PHONE IS NULL OR CALLS.DATE = "02/28/12") <<<<<<<< Exactly; but I believe that this is the right thing: SELECT * FROM CUSTOMERS LEFT JOIN CALLS USING(PHONE) WHERE CUSTOMERS.DATE = "02/28/12" OR CALLS.DATE = "02/28/12" If you have a hit --PHONE found in both tables--, you will get a record if either date matches, and I believe that you wanted that. If it is a miss --there is no CALLS-record for the PHONE-- CALLS.DATE will be NULL and not equal and only CUSTOMERS.DATE will match a date. And if this works, surely it is clear where to put BETWEEN. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/mysql
