Hi All,
I use
SELECT COUNT(*) FROM whatever WHERE whatever
to determine how many rows a particular query will return (then use this count to assist with pagination).
The problem is that this does not work if the query contains a GROUP BY statement as, of course,
the query will return many rows each with a count by each grouping.
Does anyone know an efficient way to determine the number of ROWS a query with a GROUP BY
statement will return (without just executing the entire query with no LIMIT statement)?
Thanks ... Ross
