My report uses the following query. select folio_number from unit_account ua where ua.folio_number in (1,2,3,4,5,6,7,8,9,10,11) order by to_number(ua.folio_number) How can i represent the IN clause in the above SQL as a parameter. If i use a string it adds a ' ' before and after and the query will not execute. How can i use an in clause so i can provide multiple account numbers in the same parameter.
