帮忙优化下这个SQL.....

[qfljm]

SELECT
A.UserId,
A.UserName,
B.DeptName,
Stars = CASE A.UserStatus WHEN 0 THEN '普通' ELSE '主管' END,
A.UserTEL,
Types = CASE A.UserType WHEN 0 THEN '锁定' ELSE '正常' END ,
A.FoundTime,
Times =(SELECT TOP 1 LogTime FROM T_SystemloggingLog WHERE UserId=A.UserId ORDER BY LogTime DESC),
IP=(SELECT TOP 1 dbo.DcodeIP(LogIp) FROM T_SystemloggingLog WHERE UserId=A.UserId ORDER BY LogTime DESC)
FROM T_SystemUser AS A LEFT JOIN T_SystemDept AS B ON A.DeptId=B.DeptId
ORDER BY A.UserId DESC

主要就是IP和Times
这两个东西,能优化下吗?
