Data Relation: SDATE > BANKCODE > CURRENCY > ERCODE

and insert No. column after new query.

How query get subtotal and total grand together?

Thanks advance. :)

Answer 1

This solution with dense_rank() , rollup and grouping_id should help:

with data as (
  select sdate, bankcode, ercode, currency, rate, 
         dense_rank() over (partition by sdate, bankcode order by ercode) rnk
    from t)
select sdate, bankcode, ercode, currency, rate, rnk,
       case when gid = 0 then 'Sub total' when gid = 1 then 'Grand total' end type
  from (
    select sdate, bankcode, ercode, currency, rate, rnk, null gid from data
    union all
    select sdate, bankcode, null, currency, sum(rate), null rnk, 
           grouping_id(sdate, bankcode, currency) rnk
      from data
      group by rollup(sdate, bankcode, currency)
      having (grouping_id(sdate, bankcode, currency) = 0 and currency = 'USD') 
          or grouping_id(sdate, bankcode, currency) = 1 )
    order by sdate, bankcode desc, decode(currency, 'USD', 1, 2), rnk

Test data and output:

create table t (SDate date, BankCode number(3), Ercode varchar2(5), 
                Currency varchar2(5), Rate number(6));
insert into t values (date '2015-08-21', 12, 'AQER', 'USD', 10 );
insert into t values (date '2015-08-21', 12, 'AQER', 'USD', 12 );
insert into t values (date '2015-08-21', 12, 'BERT', 'EUR', 14 );
insert into t values (date '2015-08-21', 12, 'POE',  'JPY', 31 );
insert into t values (date '2015-08-21',  9, 'AQER', 'USD', 15 );
insert into t values (date '2015-08-21',  9, 'HUIO', 'USD', 08 );
insert into t values (date '2015-09-01',  9, 'AQER', 'USD', 45 );
insert into t values (date '2015-09-01',  9, 'AQER', 'USD', 11 );
insert into t values (date '2015-09-01',  9, 'JIOW', 'EUR', 47 );

Answer 2

My first thought was

sum(rate) over (partition by bankcode, currency)

but there is a group EUR/JPY.. You need to be more specific what do you want to accomplish. In my opinion this subtotal and grandtotal could be done, but in pl/sql fe if You want to get 2 rows, calculate sub, get next 2 rows, calculate grand etc. And most important - what IS sub and grand?

Answer 3

Rollup has to help you

Try this:

SELECT SDATE, BANKCODE,  CURRENCY, ERCODE,
       SUM(Rate) AS Rate
FROM   your_table
GROUP BY ROLLUP (SDATE, BANKCODE,  CURRENCY, ERCODE)
ORDER BY SDATE, BANKCODE,  CURRENCY, ERCODE;
