SELECT DISTINCT
      , LoginLog.LoginIP, LoginLog.LoginTime,
      , , Member.LoginCount
FROM LoginLog INNER JOIN
      Company ON = INNER JOIN
      Member ON LoginLog.MemberID = Member.MemberID
WHERE ( > 0)
ORDER BY LoginLog.LoginTime DESC

语句不对吗?

你没指明根据哪个字段去重复项

能在说详细点吗

SELECT DISTINCT
      , LoginLog.LoginIP, LoginLog.LoginTime,
      , , Member.LoginCount
FROM LoginLog INNER JOIN
      Company ON = INNER JOIN
      Member ON LoginLog.MemberID = Member.MemberID
WHERE ( > 0)
ORDER BY LoginLog.LoginTime DESC

怎么指定的 DISTINCT

DISTINCT 对单列有用多列没用
