SELECT Q.mem_id
FROM tb_mem_share Q,
tb_member Mb
WHERE Mb.mem_id = Q.mem_id
AND Q.share_num_from BETWEEN '42368' AND '42378'
SELECT *
FROM tb_mem_share
WHERE share_num_from >= 42368
AND share_num_from <= 42378
运行这个我只获得第二条记录:
mem_id | share_num_from | share_num_to | no_of_shares | share_amt
-----------+------------------+----------------+----------------+--------------
KA003871 | 42360 | 42369 | 10 | 10000
KA000401 | 42370 | 42379 | 10 | 10000
我做错了什么?
答案 0 :(得分:2)
share_num_from是42360,不在“42368”和“42378”之间

不确定您要执行的操作,但是如果您想根据来自&amp;和/或至于列,您至少应该在您的选择中包含它们:
SELECT *
FROM tb_mem_share
WHERE share_num_from >= 42368
AND share_num_to <= 42378;
目前您正在过滤两次。
