How to count all rows when using SELECT with LIMIT in MySQL query?

Question

I\'ve got a mysql query like this:

FROM table1 A
JOIN table2 B ON ( A.ID = B.TABLE1_ID )
WHERE
    cond1, cond2, ..., condN

You can use the SQL_CALC_FOUND_ROWS with FOUND_ROWS() to count the number of results while that query is executing. Basically you just add 'SQL_CALC_FOUND_ROWS' after 'SELECT' and then run another query 'SELECT FOUND_ROWS()' after that. It is not possible to send back the count in the same query because it cannot know the count until the query is finished.
