我有这样的查询:
SELECT DISTINCT(obt.oid) AS oid, o.borrower_email
FROM `order_borrower_tracker` obt
LEFT JOIN `orders` o ON obt.oid=o.oid
WHERE obt.date_acknowledged_edelivery = 0
AND 18 NOT IN
(SELECT DISTINCT(new_status) AS new_status
FROM `order_status_history`
WHERE oid=obt.oid)
哪个有效,但现在我需要更新此查询,以便不仅仅是" 18"不是在子选择中,而是在其他几个数字......类似
SELECT DISTINCT(obt.oid) AS oid, o.borrower_email
FROM `order_borrower_tracker` obt
LEFT JOIN `orders` o ON obt.oid=o.oid
WHERE obt.date_acknowledged_edelivery = 0
AND (18,27,29,41,53) NOT IN
(SELECT DISTINCT(new_status) AS new_status
FROM `order_status_history`
WHERE oid=obt.oid)
但显然"(18,27,29,41,53)不在"不起作用。
实现这一目标的有效方法是什么?不为每个数字键入AND
答案 0 :(得分:2)
使用LEFT JOIN和IS NULL的技巧来查找没有列出状态的任何记录的订单:
SELECT DISTINCT(obt.oid) AS oid, o.borrower_email
FROM `order_borrower_tracker` obt
LEFT JOIN `orders` o
ON obt.oid=o.oid
LEFT JOIN `order_status_history` h
ON h.oid=obt.oid AND h.new_status IN (18,27,29,41,53)
WHERE obt.date_acknowledged_edelivery = 0
AND h.oid IS NULL
