连接多个表？

-2

declare @table1 table (sno int,transferbirds int,noofbirds int,numofbirds int,mortality int) 
insert into @table1 

select sno,Branch,isnull((select transferbirds from K_RT_RetailsDetails where branch in (PN.sno),0) as Totalbirds,  
isnull(select noofbirds from K_RT_WarehouseDetails where branch in (PN.sno),0) as Meatbirds, 
isnull(select noofbirds from K_RT_MasterBirdsTransferDet where frombranch in (PN.sno),0) as TransferBirds, 
isnull(select mortality from K_RT_DailyEntry where branch in (PN.sno),0)as Mortality, 
isnull(select noofbirds from K_RT_BirdsTransfer where branch in (PN.sno),0) as Tobranchtransferbirds 
from K_RT_MasterRetailStores PN  

select * from @table1

不能使用'ISNULL（SELECT a FROM b，0）'你需要在整个子查询中放置'（）'...... ISNULL（（SELECT a FROM b），0）'。你开始为第一个子查询*（你有'（'但不是'）'）* – MatBailie

现在你有语法错误。修复这个问题后你再次得到错误，因为你的子查询可以返回多于一行。为什么不简单地使用K_RT_MasterRetailStores连接每个表PN – KumarHarsh

你可以试试这个：

declare @table1 table (sno int,transferbirds int,noofbirds int,numofbirds int,mortality int) 
insert into @table1 

select sno,Branch, 
isnull((select transferbirds from K_RT_RetailsDetails where branch in (PN.sno)),0) as Totalbirds,  
isnull((select noofbirds from K_RT_WarehouseDetails where branch in (PN.sno)),0) as Meatbirds, 
isnull((select noofbirds from K_RT_MasterBirdsTransferDet where frombranch in (PN.sno)),0) as TransferBirds, 
isnull((select mortality from K_RT_DailyEntry where branch in (PN.sno)),0)as Mortality, 
isnull((select noofbirds from K_RT_BirdsTransfer where branch in (PN.sno)),0) as Tobranchtransferbirds 
from K_RT_MasterRetailStores PN  

select * from @table1

其实内部的选择语句包含圆括号

它显示子查询返回的值超过1个。 – Sambasiva

然后你内部的选择是不正确的。例如，如果问题出现在表K_RT_RetailsDetails中，则表示您有两行用于同一分支。如果值相同，您可以尝试在每个内部选择中使用不同的...例如。 isnull（（从...选择不同的转移鸟 – vkamayiannis
