SELECT * FROM budgetingdb UNION 
SELECT * FROM chain_management UNION
SELECT * FROM accountpayable
WHERE DATE >= DATE_SUB(CURDATE(), INTERVAL 7 DAY) ORDER BY curtime DESC";

SELECT * FROM adagio_accounting_suite UNION
SELECT * FROM billquick UNION 
SELECT * FROM budgetingdb UNION 
SELECT * FROM chain_management UNION
SELECT * FROM accountpayable) as XYZ
WHERE DATE >= DATE_SUB(CURDATE(), INTERVAL 7 DAY) ORDER BY curtime DESC";
