SQL子查询从返回的结果中选择

Question

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

这将返回包含ip和count列的表。我想选择count = 1 OR 1＆lt;计数＆lt; 6

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

试试这个：

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

HAVING子句是聚合函数的WHERE

Answer 3

使用： -

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