Dear Friend,

You can use Distinct or Group by or Top 1.
It will help you. But make sure that, your requirement is fulfilled.

Instead of =, use In

I think your query will be looking something like

SQL

select * from employee where empid=(select empid from employee where dept='SE')

So now what happens, the subquery will return you more than one row but since you mentioned condition'=', it returns error.

In that case, you have to use IN or exists

SQL

select * from employee where empid in (select empid from employee where dept='SE')

In case if you used !=, then use not in.

But note: Not in will affect performance use not exists
