hi,

this query works:

select ap.*
from date_lookup d
outer apply
dbo.udf_ActivePlacementNumbersByDay(d.date_full) ap
where d.date_full >= '20130101'
and d.date_full <= '20130103'

yet this one doesn't (it hangs):

declare @startDate date
declare @endDate date

set @startDate = '20130101'
set @endDate = '20130103'

select ap.*
from date_lookup d
outer apply
dbo.udf_ActivePlacementNumbersByDay(d.date_full) ap
where d.date_full >= @startDate
and d.date_full <= @endDate

I'm assuming this must be a data type issue for the date variables. Can someone assist me in how I can pass a variable into this query and what data types to use correctly.

If you need more context about the query - please let me know.

It could be because of a bad execution plan, or it could be because of the data types. Whether it is due to data types is easy to check change your WHERE clause to:
where d.date_full >= CAST(@startDate as DATE)
and CAST(d.date_full <= @endDate as DATE)

Is this used in a stored procedure? If so, it's possible you might be a victom of parameter sniffing.
