Sql server 从多个表中获取值

请帮助我查询SQL中六（6）个表中的值

以下是表格：

select Pid from BillOrderTbl
select Pid from CustomerCreditItm
select Pid from SalesBillOrderTbl
select Pid from SalesOrderItm
select Pid from VendorCreditItm
select Pid from OrderItm

我正试着这样做

select OrderItm.Pid, BillOrderTbl.Pid, CustomerCreditItm.Pid, SalesBillOrderTbl.Pid, SalesOrderItm.Pid, VendorCreditItm.Pid
from OrderItm
inner join BillOrderTbl on BillOrderTbl.Pid = OrderItm.Pid
inner join CustomerCreditItm on BillOrderTbl.Pid = CustomerCreditItm.Pid
inner join SalesBillOrderTbl on CustomerCreditItm.Pid = SalesBillOrderTbl.Pid
inner join SalesOrderItm on SalesBillOrderTbl.Pid = SalesOrderItm.Pid
inner join VendorCreditItm on SalesOrderItm.Pid = VendorCreditItm.Pid

我得到这个输出

但实际上，

OrderItm.Pid

列中有数据。

试试这个：

SELECT *
FROM (
    SELECT Pid FROM BillOrderTbl
    UNION ALL
    SELECT Pid FROM CustomerCreditItm
    UNION ALL
    SELECT Pid FROM SalesBillOrderTbl
    UNION ALL
    SELECT Pid FROM SalesOrderItm
    UNION ALL
    SELECT Pid FROM VendorCreditItm
    UNION ALL
    SELECT Pid FROM OrderItm
) MyTables

其中一个表中必须缺少一条记录，

内部联接

要求存在匹配项，可能需要

左联接
