Im using TIBOQuery.

How can I easily query an integer column to get all the rows matching
an integer or also allow all rows to be fetched? EG:

Item.Project (integer)
Item.Location (integer)

(Case 1)
Select * from Item where
Project = :ProjectID and Location = :LocationID

(Case 2)
Select * from Item where
Project = :ProjectID and Location = all locations

Thanks
