Question

I have a table my_ids with single column id. Next, I have a table-valued function fn_getMatches(id). What I want is to iterate through table my_ids and for each id call function fn_getMatches(id) and aggregate all results in one table. How do I do that without explicit loop?

I tried:

select *
from my_ids ids
     full outer join fn_getMatches(ids.id) on 1=2
where ids.id is null

But it returns:

Msg 4104, Level 16, State 1, Line 11
The multi-part identifier “ids.id” could not be bound.

Answer 1

Having no idea what the function does, or what results you expect, maybe try:

select * -- name your columns!
from dbo.my_ids AS ids -- use schema prefix!
cross apply dbo.fn_getMatches(ids.id); -- use schema prefix!

Removed the WHERE clause and the ON criteria from your initial attempt.
