MySQL内部联接查询提供重复的结果

I have written a query using inner join which consist of multiple tables

我使用内连接编写了一个查询，该连接由多个表组成

SELECT     * 
FROM       admin_info 
INNER JOIN admin_login 
INNER JOIN gender 
INNER JOIN admin_type 
INNER JOIN area 
INNER JOIN document_type 
INNER JOIN permissions 
ON         admin_login.admin_id=admin_info.admin_id 
AND        admin_type.admin_type_id=admin_info.admin_type_id 
AND        area.area_id=admin_info.area_id 
AND        document_type.document_id=admin_info.document_id 
AND        permissions.permission_id=admin_info.permission_id

The above query works but gives multiple results of the same record or duplicate records Please help me fix the query or provide with an alternative to this query also please suggest me ways to optimize the query for faster processing??

Actually The problem was with gender table which had no reference in the query as soon as i removed the gender table inner join it worked as expected!

实际上问题是性别表，一旦我删除性别表内连接它没有参考，它按预期工作！
