确定如何在这里完成标题......
但是,下面是我试图开始工作的MySQL查询(它已被破坏)
我想要实现的目标如下:
REP = 0 im AS deviceim
和
REP = 1 im AS replaceim
SELECT tb1.*, tb2.id AS iii, tb2.im as deviceim, (SELECT tb2.im FROM tb2 WHERE tb2.REP LIKE '1' AND tb1.filter IN ('SEPID1','SEPID2'...) ) AS replacementim
FROM tb1 LEFT OUTER JOIN tb2 ON tb1.id = tb2.orderid
AND tb2.REP LIKE '0' WHERE filter IN ('SEPID1','SEPID2'...)
ORDER BY filter
根据要求提供更多信息进行编辑
数据
Table 1
id
1
Table 2
id//////orderid//im/////REP
34567//////1///654311////0
63219//////1///827364////1
通缉输出:
id//deviceim/replacementim
1////654311/////827364
PS:我对格式化很抱歉!!
