MySQL 视图 第1349号错误解决方法

CREATE OR REPLACE VIEW BLOG_V_ADMIN  
(ID,NICKNAME,SEX,EMAIL,PHONE,QQ,MSN,HTTP,REGISTER_TIME,  
IP,LAST_LOGIN_IP,LOGIN_TIME)  
AS  
SELECT  
 A.ID,A.NICKNAME,A.SEX,A.EMAIL,A.PHONE,A.QQ,A.MSN,A.HTTP,A.REGISTER_TIME,  
 B.IP AS LAST_LOGIN_IP,B.LOGIN_TIME AS LAST_LOGIN_TIME  
FROM  
 BLOG_ADMIN A LEFT JOIN  
 BLOG_ADMIN_LOGIN_TRACK B ON B.ADMIN = A.ID LEFT JOIN  
 (SELECT ADMIN,MAX(LOGIN_TIME) AS LOGIN_TIME FROM BLOG_ADMIN_LOGIN_TRACK GROUP BY ADMIN) C ON B.ADMIN = C.ADMIN; 

ERROR 1349 (HY000): View's SELECT contains a subquery in the FROM clause
这是BUG吗?见:http://bugs.mysql.com/bug.php?id=16757


木有办法,我只好这样改了:

CREATE OR REPLACE VIEW BLOG_V_ADMIN  
(ID,NICKNAME,SEX,EMAIL,PHONE,QQ,MSN,HTTP,REGISTER_TIME,  
LOGIN_TIME,LAST_LOGIN_IP)  
AS  
SELECT  
 A.ID,A.NICKNAME,A.SEX,A.EMAIL,A.PHONE,A.QQ,A.MSN,A.HTTP,A.REGISTER_TIME,  
 (SELECT LOGIN_TIME FROM BLOG_ADMIN_LOGIN_TRACK WHERE ADMIN = A.ID ORDER BY LOGIN_TIME DESC LIMIT 1) AS LAST_LOGIN_TIME,  
 (SELECT INET_NTOA(IP) FROM BLOG_ADMIN_LOGIN_TRACK WHERE ADMIN = A.ID ORDER BY LOGIN_TIME DESC LIMIT 1) AS LAST_LOGIN_IP  
FROM  
 BLOG_ADMIN A;
