如何從多個表中獲取7天的數據

Question

從mysql中的多個表中獲取7天的數據。

這是我的select語句：

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

Answer 1

你可以嘗試使用這個：

$sql="SELECT * FROM (SELECT * FROM chain_management UNION 
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";
