See my query problem for sub query

Question

hi master
Sir see my query
select lpad(' ',2*(level-1)) || to_char(chartofacc.child),parent,accid as accounted ,title,
case when fstatus=1 then
(select sum(drbal) from accbal where parent = accounted)
when fstatus is null then
(select drbal from accbal where accid = accounted)
end subtotal
from chartofacc
start with chartofacc.parent is null
connect by prior chartofacc.child = chartofacc.parent order by chartofacc.accid
I try but not success how I pass main query value or code in sub query or inner query
My requirement is inner query get total from accbal table how have accid that in main query accid or accounted
How I pass main query value or accid code to inner query and inner query give result as per main query accid
How I get subtotal and total by one query
Please give me idea or code
Thanking you

You could write your main SELECT statement as inline view or use the WITH clause, like this:
WITH ctf AS (SELECT LPAD (' ', 2 * (LEVEL - 1)) || TO_CHAR (chartofacc.CHILD), PARENT,
                    accid AS accounted, title,
               FROM chartofacc
              START WITH chartofacc.PARENT IS NULL
              CONNECT BY PRIOR chartofacc.CHILD = chartofacc.PARENT
              ORDER BY chartofacc.accid
SELECT ctf.*,
       CASE WHEN fstatus = 1
            THEN (SELECT SUM (drbal)
                    FROM accbal
                   WHERE PARENT = accounted)
            WHEN fstatus IS NULL
            THEN (SELECT drbal
                    FROM accbal
                   WHERE accid = accounted)
       END subtotal
  FROM ctf
