選擇beetween日期和有限的IP

Question

我創建了一個日期和有限的IP之間的簡單登錄系統，但MySQL查詢給我一些錯誤。

我想控制用戶是否登錄更多的則有限的IP和有限的日期

之間

這是一個MySQL查詢：

SELECT *, count(l.ip) as total FROM login_card as c 
INNER JOIN cart_log as l 
WHERE c.login_name = "toruser" AND c.login_pass = "54trvd" 
AND l.dt > DATE_SUB(now(), INTERVAL c.end_dt MONTH) 
AND total > c.total_ip 

Answer 1

SELECT User.* 
FROM 
login_card User 
INNER JOIN 
(SELECT userid,COUNT(DISTINCT `ip`) as Total_ips 
    FROM 
    cart_log 
    INNER JOIN login_card ON login_card.`userid`=cart_log.`userid` AND cart_log.dt > DATE_SUB(now(), INTERVAL login_card.end_dt MONTH) 
    group by userid) T ON User.`userid` = T.`userid` AND T.`Total_ips` > User.`total_ip` 
WHERE User.login_name = 'toruser' AND User.login_pass = '54trvd' 

希望這有助於。

Answer 2

試試這個....

SELECT *, count(l.ip) as total FROM login_card as c 
INNER JOIN cart_log as l 
WHERE c.login_name = "toruser" AND c.login_pass = "54trvd" 
AND l.dt > DATE_SUB(now(), INTERVAL c.end_dt MONTH) 
AND count(l.ip) > c.total_ip 

讓我知道你會得到什麼？
