Query to display multiple counts in the result

Question

Hi,
I need to be able to display multiple counts for different items in the single result set:
Here is the simplified schema:
I have 2 tables:
STATEMENT table:
===============
statement_pk number,
department varchar2(20)
STATEMENT_INFO table:
===================
statement_info_pk number,
statement_fk number
is_statement_done varchar2(1)
is_statement_locked varchar2(1)
I need to display counts of how many records where done and how records where locked in the
single output:
Statement_PK Department NumberOfStatementsDone# NumberofStatementsLocked#
1          ABC_dept          3                    5
2          DEF_dept          4                    8
3          XYZ_dept          7                    2
The following does not work:
SELECT
s.statement_pk,
s.department,
COUNT(r.statement_info_pk ) NumberOfStatementsDone# ,
COUNT(rr.statement_info_pk ) NumberOfStatementsLocked#
FROM STATEMENT s ,
STATEMENT_INFO r,
STATEMENT_INFO rr
WHERE
     s.statement_pk = r.statement_fk
     AND     s.statement_pk = rr.statement_fk
     AND      is_statement_done = 'Y'      AND rr.is_statement_locked = 'Y'
GROUP BY statement_pk, s.department
I was trying to work with analytic function but could not figured it out either.
Please help
Thanks,
Ia.

Answer 1

this would be something like:
SQL> r
  1  select statement_pk,
  2         department,
  3         sum(decode(is_statement_done, 'Y', 1, 0)) statement_done,
  4         sum(decode(is_statement_locked, 'Y', 1, 0)) statement_locked
  5  from   statement_info,
  6         statement
  7  where  statement_fk = statement_pk
  8* group by statement_pk, department
STATEMENT_PK DEPARTMENT           STATEMENT_DONE STATEMENT_LOCKED
           1 ABC_dept                          4                1
           2 DEF_dept                          6                2
           3 XYZ_dept                          1                2
