Use two queries unless you are using MySQL 4.0+
FOUND_ROWS()
Returns the number of rows that the last SELECT SQL_CALC_FOUND_ROWS ...
command would have returned, if wasn't restricted with LIMIT.
mysql> SELECT SQL_CALC_FOUND_ROWS * FROM tbl_name
WHERE id > 100 LIMIT 10;
mysql> SELECT FOUND_ROWS();
The second SELECT will return a number indicating how many rows the first
SELECT would have returned had it been written without the LIMIT clause.
Note that if you are using SELECT SQL_CALC_FOUND_ROWS ... MySQL has to
calculate all rows in the result set. However, this is faster than if you
would not use LIMIT, as the result set need not be sent to the client.
SQL_CALC_FOUND_ROWS is available starting at MySQL version 4.0.0.
