Question

I’d like to do something along the lines of

select * from table where column < myValue,

and myValue is obtained by

select myValue from table where id = @id --there should only be one.

How can I combine these?

I tried where in, but with no success.

Answer 1

What about something like this?

declare @myValue int -- value type
select top(1) @myValue = myValue from table where id = @id --there should only be one.
select * from table where column < ISNULL(@myValue,0);
