sql - How To Combine These 2 Queries into one Query without using union - 


select b.kpcno          ,b.kpc_full_name      xxkpc_hr_personnel_v2  b  b.type(+) = 'kpc employee'        , b.designation null        , b.kpcno not null        , b.organization_id=(select g.organization_id  xxkpc_fn_web_personnel_v g g.kpcno = :kpcno) group b.kpcno           ,b.kpc_full_name  union  select b.kpcno          ,b.kpc_full_name xxkpc_hr_pos_struct_code_comb        ,xxkpc_hr_personnel_v2  b b.position_id(+) = a.child_position_id        , b.type(+) = 'kpc employee'        , b.kpcno not null        , a.perant_position_id =  (select g.position_id  xxkpc_fn_web_personnel_v g g.kpcno = :kpcno) group b.kpcno           ,b.kpc_full_name

please need combine these 2 queries 1 query without using union

i think can write like:

select distinct b.kpcno, b.kpc_full_name   xxxkpc_hr_personnel_v2 b  b.type(+) = 'kpc employee'    , b.kpcno not null    , (          (b.designation null ,           b.organization_id in (select g.organization_id                                   xxkpc_fn_web_personnel_v g                                   g.kpcno = :kpcno))          or         (b.position_id in (select a.child_position_id                              xxkpc_hr_pos_struct_code_comb                             a.parent_position_id = (select g.position_id                                                             xxkpc_fn_web_personnel_v g                                                             g.kpcno = :kpcno)))        )

as far see using group by make result distinct, used proper key word. , a , b not left joined, because in next anded clause saying a.parent_position_id = .....
