計算表中字段重複次數超過5次的行

Question

獲取表中的用戶帳戶列表，並附帶IP地址。

我需要運行一個查詢，只顯示具有超過5個相同IP的行。

我有一個查詢，但我已經失去了它

（我需要ID，用戶名和LAST_IP返回） - LAST_IP也是其中的IP存儲做計數

Answer 1

這裏是一個例子：

declare @table table (user_id int identity(1, 1), user_name varchar(100), last_ip varchar(50)) 

insert into @table (user_name, last_ip) values ('joe moe', '192.168.0.XX') 
insert into @table (user_name, last_ip) values ('xyz', '192.168.0.XX') 
insert into @table (user_name, last_ip) values ('dummy', '192.168.0.XX') 
insert into @table (user_name, last_ip) values ('harry potter', '192.168.0.XX') 
insert into @table (user_name, last_ip) values ('he who should not be named', '192.168.0.XX') 
insert into @table (user_name, last_ip) values ('times square', '192.168.0.XX') 
insert into @table (user_name, last_ip) values ('user1', '192.168.0.YY') 
insert into @table (user_name, last_ip) values ('user2', '192.168.0.YY') 
insert into @table (user_name, last_ip) values ('user3', '192.168.0.YY') 
insert into @table (user_name, last_ip) values ('user4', '192.168.0.YY') 
insert into @table (user_name, last_ip) values ('user5', '192.168.0.YY') 
insert into @table (user_name, last_ip) values ('user6', '192.168.0.YY') 
insert into @table (user_name, last_ip) values ('tom dick harry', '192.168.0.ZZ') 
insert into @table (user_name, last_ip) values ('peter pan', '192.168.0.ZZ') 
insert into @table (user_name, last_ip) values ('humpty dumpty', '192.168.0.ZZ') 
insert into @table (user_name, last_ip) values ('red riding hood', '192.168.0.ZZ') 
insert into @table (user_name, last_ip) values ('tintin', '192.168.0.ZZ') 
insert into @table (user_name, last_ip) values ('mickey mouse', '192.168.0.ZZ') 
insert into @table (user_name, last_ip) values ('only user', '192.168.0.AA') 

select a.* from @table a 
inner join 
(
    select last_ip, count(*) as cnt from @table 
    group by last_ip 
    having count(*) > 5 
) allCounts 
on a.last_ip = allCounts.last_ip 

Answer 2

這聽起來像你需要做的是這樣的：

SELECT ID，USERNAME，LAST_IP，通過ID，USERNAME COUNT（*）作爲CNT從TABLE_NAME組，LAST_IP HAVING COUNT（*）> 5 ORDER BY CNT DESC
