Hi, We are getting following error while running the following query: SELECT accmap.id_acc as id_acc, av.c_firstname as firstname, av.c_lastname as lastname, av.c_middleinitial as middleinitial, av.c_zip as zip FROM Tab1 accmap LEFT OUTER JOIN tab2 av ON av.id_acc = accmap.id_acc AND av.c_contacttype = (SELECT id FROM tab3 ed WHERE ed.nm = 'bill-to') WHERE accmap.id_acc in (345) SELECT * ERROR at line 1: ORA-01799: a column may not be outer-joined to a subquery What is the other possible option to rewrite this query as a workaround for this error? (We can't move the AND clause after where since that will change the semantics of the query) Thanks --Harvinder
