the subquery(select IsActivated from tblSuperSellDetail where SellId=7) reutrning more than one value. so use top 1 clause with select to fetch only one record or Distinct clause

ex:

SQL

select Top 1IsActivated from tblSuperSellDetail where SellId=7

or

SQL

select Distinct(IsActivated) from tblSuperSellDetail where SellId=7

Try this:

SQL

select a.billamt,b.itemcode,(select TOP(1) IsActivated from tblSuperSellDetail where SellId=7) as isactivated
from tblSellMaster a inner join tblSellDetail b on a.SellId =b.SellId
where a.SellId =7

NOTE: This is not prefered solution. Rather then using subquery, use JOIN to join next table ;)
