SQL

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

I have guess that you want count of total birds so i put count in subquery as per your requirements you can use count, sum, top 1 .

Here the logic is whenever you uses subquery , the result of subquery should have one and only one, not more then one row.

Please comment me if you want more detail.
