Another Oracle Question

[Ardesco]

Is there a way to get the number of result rows returned and use that number as a footer?

e.g.

SELECT 'HEADER - HEADER ROW HERE' FROM DUAL
UNION ALL
SELECT A,B,C
FROM MY_TABLE
UNION ALL
SELECT 'FOOTER - TOTAL NUMBER OF ROWS RETURNED =' <INSERT ROW COUNT HERE> FROM DUAL

I've tried using rownum, but it doesn't give me total number of rows output, only total number of rows in the current select statment (i.e. 1).

SELECT 'HEADER - HEADER ROW HERE' FROM DUAL
UNION ALL
SELECT A,B,C
FROM MY_TABLE
UNION ALL
SELECT 'FOOTER - TOTAL NUMBER OF ROWS RETURNED = '||count(*) from MY_TABLE


This should work, but I'm not at work today, so I haven't been able to try it.

that will work but you are hitting the same records twice which is not very efficient. Depends on how big the result set is but a more efficient way is to use pl/sql and have it in a cursor and loop through...
