SQL*Plus Custom Summary Report - oracle

Question

I have a requirement to generate the following summary report that look like the following:
My problem is that,
I have no idea on how do I fill the count data in this custom report.
I do not know how to put it in a table view like the above in a text document. It is not HTML.
So far, I only know how to do the first row, and column without the table view.
Here are my codes.
SET HEADING OFF;
SET LINESIZE 200;
SET SPACE 0;
SET ECHO OFF;
SET FEEDBACK OFF;
SET VERIFY OFF;
SET MARKUP HTML OFF SPOOL OFF;
SET TERMOUT OFF; --Do not show output to the screen.
SET NEWPAGE NONE; --Remove the first blank line at the top of the page and between queries.
TTITLE LEFT "REPORT NAME" RIGHT "PAGE : " SQL.PNO SKIP 1 -
LEFT "--------------------------------" RIGHT "DATE : " _DATE SKIP 1 -
LEFT "A) TOTAL RECORDS " RIGHT total_records; -- Cannot output variable in the title.
LEFT "B) MATCHED RECORDS " RIGHT matched_records; -- Cannot output variable in the title.
LEFT "C) UNMATCHED RECORDS " RIGHT matched_records; -- Cannot output variable in the title.
BTITLE LEFT "E N D";
total_records is an insert into statement.
SELECT COUNT(*) INTO total_records FROM TABLE;
I have not done matched records and unmatched records. But the only way I can think of
Select a statement into a cursor.
Loop into the cursor.
Increase matched count when there is a match.
Once loop finish. unmatched count = total count - matched count.
I don't think this is the most efficient way. But, if you have a better way, let me know.

Answer 1

Does something like this ring a bell? Example is based on Scott's sample schema:
SQL> select 'Total records' name, count(*) cnt
2 from emp
3 union all
4 select 'Matched count', sum(case when deptno = 10 then 1 else 0 end)
5 from emp
6 union all
7 select 'Unmatched count', sum(case when deptno = 10 then 0 else 1 end)
8 from emp;
NAME CNT
--------------- ----------
Total records 14
Matched count 3
Unmatched count 11
