Mysql 连接与使用相关名称的子查询连接

Question

我尝试使用MySQL连接与子查询，子查询也有连接，所以我面临问题，请友善，因为我不是不尝试就问，我尽力解决，但出现语法错误，这是因为关联名称 t1 和 t2

SELECT min(user_org.oid) as id, user_org_profiles.name from user_org
LEFT JOIN user_org_profiles ON (user_org.oid = user_org_profiles.oid) t1
INNER JOIN
    (SELECT user_org_profiles.name, max(user_org.gid) as gid
     FROM user_org LEFT JOIN user_org_profiles USING(oid)
     WHERE user_org.gid IN (1,2]) AND active =1 
     group by name) t2 ON t1.name = t2.name AND t1.gid = t2.gid group by t1.name

出现此错误

1064 - 您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，了解在 ']) AND active =1 group by name) ON t1.name = t2.name AND t1.gid = t2.' 附近使用的正确语法。在第 6 行

修复了将 user_org_profiles 别名为 t1 以及 IN 列表中的一个小拼写错误的问题。不过，这些错误与消息中报告的文本不太接近。

SELECT min(user_org.oid) as id, t1.name from user_org
LEFT JOIN user_org_profiles t1 ON (user_org.oid = t1.oid)
INNER JOIN
    (SELECT user_org_profiles.name, max(user_org.gid) as gid
     FROM user_org LEFT JOIN user_org_profiles USING(oid)
     WHERE user_org.gid IN (1,2) AND active = 1 
     group by name) t2 ON t1.name = t2.name AND t1.gid = t2.gid group by t1.name
