我试过这个查询但是得到了空

select t1.Name,t1.Date,t1.Item,t1.Remarks
from t1 p1
inner join t2 on t1.Name=t2.Name
inner join t3 on t1.Name=t3.Name
inner join t4 on t1.Name=p4.Name
inner join t4 on t1.Name=p5.Name
inner join t5 on t1.Name=p6.Name
inner join t6  on t1.Name=p2.Name
where t1.CheckListName='abc'

Answer 1

联盟将从所有表中选择与返回相同行的贫困行。尝试，

select Name, Date, Item, Remarks
from t1 where name = 'abc'

UNION 

select Name, Date, Item, Remarks
from t2 where name = 'abc'

UNION 

select Name, Date, Item, Remarks
from t3 where name = 'abc'

UNION 

select Name, Date, Item, Remarks
from t4 where name = 'abc'

UNION 

select Name, Date, Item, Remarks
from t5 where name = 'abc'    
UNION 

select Name, Date, Item, Remarks
from t6 where name = 'abc'

Answer 2

试试这个

SELECT * FROM (
        SELECT * FROM t1
        UNION ALL
        SELECT * FROM t2
        UNION ALL
        SELECT * FROM t3
        UNION ALL
        SELECT * FROM t4
        UNION ALL
        SELECT * FROM t5
        UNION ALL
        SELECT * FROM t6
               ) AS Total
WHERE NAME = 'abc'

我认为你不应该有任何错误。
