Mysql My SQL为每个SQL中的两个表联接返回重复的UNION条目

查询

( select c.client_id, c.fname, c.lname, c.type_id, c.short_description, ct.name 
from client c , client_type ct where fname = 'Ade Kannu ' and ct._id = c.type_id)

我的sql返回重复项

在同样的情况下

( select c.client_id, c.fname, c.lname, c.type_id, c.short_description 
from client c where fname = 'Ade Kannu ') 
UNION
( select c.client_id, c.fname, c.lname, c.type_id, c.short_description 
from client c  where c.lname = 'Ade Kannu ')
UNION
 ( select c.client_id, c.fname, c.lname, c.type_id, c.short_description from client c   where c.fname like '%Ade Kannu %')
 UNION 
 ( select c.client_id, c.fname, c.lname, c.type_id, c.short_description from client c   where c.lname like '%Ade Kannu %')  
 UNION 
 ( select c.client_id, c.fname, c.lname, c.type_id, c.short_description from client c   where c.title_content like '%Ade Kannu %' or c.key_value like '%Ade Kannu %' )
 UNION 
 ( select c.client_id, c.fname, c.lname, c.type_id, c.short_description from client c   where c.fname like '%Ade%' or c.lname like '%Ade%'  or c.title_content like '%Ade%' or c.key_value like '%Ade%')  
 UNION 
 ( select c.client_id, c.fname, c.lname, c.type_id, c.short_description from client c   where c.fname like '%Kannu%' or c.lname like '%Kannu%'  or c.title_content like '%Kannu%' or c.key_value like '%Kannu%')  
 UNION 
 ( select c.client_id, c.fname, c.lname, c.type_id, c.short_description from client c   where c.fname like '%' or c.lname like '%'  or c.title_content like '%' or c.key_value like '%') limit 0, 10

它不会返回副本

基本上，我想要

客户机\u type

名称

，它在另一个表中，它的外键在

客户机

表中。谁能帮我一下吗？你可以使用不同的功能。像这样

select distinct client_id, fname, lname, type_id, short_description  from (
( select c.client_id, c.fname, c.lname, c.type_id, c.short_description 
from client c where fname = 'Ade Kannu ') 
UNION
( select c.client_id, c.fname, c.lname, c.type_id, c.short_description 
from client c  where c.lname = 'Ade Kannu ')
UNION
 ( select c.client_id, c.fname, c.lname, c.type_id, c.short_description from client c   where c.fname like '%Ade Kannu %')
