mysql - 从返回的结果中选择 SQL 子查询

Question

SELECT ip, COUNT(ip) as count FROM gnb_full_log GROUP BY ip

这将返回带有 ip 和 count 列的表。我想选择 count = 1 OR 1 < count < 6 的记录

Answer 1

使用HAVING子句：

SELECT   ip, COUNT(*) as count
FROM     gnb_full_log
GROUP BY ip
HAVING   count = 1

或者

SELECT   ip, COUNT(*) as count
FROM     gnb_full_log
GROUP BY ip
HAVING   1 < count AND count < 6

Answer 2

尝试这个：

SELECT ip, COUNT(ip) as count 
FROM gnb_full_log GROUP BY ip
HAVING COUNT(ip) >= 1 and COUNT(ip) < 6

HAVING 子句在聚合函数上是 WHERE

Answer 3

用这个：-

SELECT ip, COUNT(ip) as count FROM gnb_full_log GROUP BY ip HAVING  count > 1 AND count < 6
