sql - Alternate solution for the query - Used INTERSECT function in oracle plsql -


i working on query. have 2 tables 1 detail table not grouping happen , including values , other table line table has important column grouped detail table.

i want show column line table , column detail table.

i using below query fetch records

select ab.*,         cd.phone_number,         cd.id    xxx_line ab,         xxx_detail cd   cd.reference_number = ab.reference_number         , cd.org_id = ab.org_id         , cd.request_id = ab.request_id         , ab.request_id = 13414224   intersect  select ab.*,         cd.phone_number,         cd.id    xxx_line ab,         xxx_detail cd   cd.reference_number = ab.reference_number         , cd.org_id = ab.org_id         , cd.request_id = ab.request_id         , ab.request_id = 13414224

the query working fine...

but want know there other way can achieve same result not using intersect.

i purpose find out possible way same output.

the intersect operator returns unique set of rows returned each query. code can re-written distinct operator make meaning clearer:

select distinct        xxx_line.*,         xxx_detail.phone_number,         xxx_detail.id    xxx_line   join xxx_detail     on xxx_line.reference_number = xxx_detail.reference_number    , xxx_line.org_id = xxx_detail.org_id    , xxx_line.request_id = xxx_detail.request_id  xxx_line.request_id = 13414224

i replaced old-fashioned join syntax newer ansi join syntax (which makes relationships clearer forcing join tables , conditions listed close each other) , removed meaningless table aliases (because code complexity more directly related number of variables number of characters).
