I already tried this construct.  But the statement comes from a stored
procedure where the {1000, 2000} is an array variable (requestIds).  I
tried to use

IT.ITIRNUM IN (requestIds) or several other variant without success.

Is there a way to make it work?  Here is the statement the statement from the store procedure.  Remenber requestIds is
anarray of int. 


FOR inventoryTransaction IN
        SELECT DISTINCT IRNUM, IRAENUM, IRSTATUT, IRSENS, IRSOURCE,
IRDATE, IRQTE
        FROM IR
        WHERE IRNUM = ANY (requestIds) and IRYPNUM = companyId
    LOOP

Thank for your help !!!!
