INNER JOIN with Table-Valued Function not working

Question

I have a table valued function that returns a table. When I try to JOIN the table-valued function with another table I don\'t get any results, but when I copy t

Answer 1

If we made some assumptions that params of table valued functions are not dependent on myTable columns dynamically this will work.

   SELECT *
    FROM myTable 
    INNER JOIN

    (SELECT * from fn_function(@para1, @para2 etc))
 ON ...

but if the params are dependent on myTable it will not work

Answer 2

I think this should work

  Select * 
    From Animals 
    Join dbo.AnimalsTypesIds(900343) 
      As AnimalsTypes
      On AnimalsTypes.TypeId = Animals.TypeId

In table valued function the return table should have TypeId so that join works on that clause

Answer 3

Your "ON" clause of the join is most likely incorrect. Perhaps a small typo like

JOIN x ON oID = odID

instead of

JOIN x ON oID = oID

Answer 4

With the table valued function you generally use Cross Apply.

Select *
From myTable m
CROSS APPLY fn_function(m.field1, m.field2)
