does sequence of columns in where condition matters the sequence of composite key? in Oracle Database here, In the code where exists clause contains all primary key columns in where, I want to know that the sequence of this columns in it, matters in query performance.

  update temp_fd_dtl_svj a
  set a.LAST_INT_PAID_DT = ( select max(b.TRAN_DT) from temp_fd_int_svj b
                              where a.COMP_CD = b.comp_cd and a.BRANCH_CD = b.BRANCH_CD and a.ACCT_CD = b.ACCT_CD
                                and a.ACCT_TYPE = b.ACCT_TYPE and a.fd_no = b.FD_NO and b.Tran_type in ('I')
                            )
  , a.LAST_PROV_DT = ( select max(b.TRAN_DT) from temp_fd_int_svj b
                              where a.COMP_CD = b.comp_cd and a.BRANCH_CD = b.BRANCH_CD and a.ACCT_CD = b.ACCT_CD
                                and a.ACCT_TYPE = b.ACCT_TYPE and a.fd_no = b.FD_NO and b.Tran_type in ('P')
                            )
   , a.LAST_TDS_DT = ( select max(b.TRAN_DT) from temp_fd_int_svj b
                              where a.COMP_CD = b.comp_cd and a.BRANCH_CD = b.BRANCH_CD and a.ACCT_CD = b.ACCT_CD
                                and a.ACCT_TYPE = b.ACCT_TYPE and a.fd_no = b.FD_NO and b.Tran_type in ('T')
                            )
  where exists (select *
                from temp_fd_int_svj c
               where a.acct_cd = c.acct_CD
                 and a.comp_cd = c.comp_cd
                 and a.BRANCH_CD = c.BRANCH_CD
                 AND a.ACCT_TYPE = c.ACCT_TYPE
                 and a.fd_no = c.FD_NO
               )
  ;
No, it will not matter. Make sure: 


Data types are same in both tables
All columns are indexed  Index
Index statistics are not stale.

SELECT stale_stats FROM user_ind_statistics
WHERE index_name = upper('&amp;index_name');
