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
