添加在MySQL查詢一個條件

Question

SELECT ord_no,name, mobile, address, rate, mrp, create_date, edited_date,status 
FROM orders o, customer c 
where o.cust_id = c.id and status = 'CHECKED' order by 1; 

我想這個條件添加到上述查詢

edited_date < DATE_SUB(now(), interval 48 hour) 

我怎樣才能做到這一點？

Answer 1

SELECT ord_no,name, mobile, address, rate, mrp, create_date, edited_date, status 
FROM orders o, customer c 
where o.cust_id = c.id 
and status = 'CHECKED' 
and edited_date < now() - interval 48 hour 

Answer 2

如果要連接兩個表，請使用JOIN運算符。

爲什麼不添加您需要的WHERE子句？它必須插入之前ORDER BY：

SELECT ord_no, name, mobile, address, rate, mrp, create_date, edited_date, status 
FROM orders o 
    INNER JOIN customer c 
     ON o.cust_id = c.id 
WHERE status = 'CHECKED' 
AND edited_date < DATE_SUB(now(),interval 48 hour) 
ORDER BY 1
