Question

I want to fetch only 20 rows from a database table using one condition
for example :

select * from orders where price > 10000 limit 0,20

Above query will fetch only 20 rows. Is there any way i can get how many rows it can fetch with same condition in WHERE clause when limit 0,20 is not used?. I have to do it in one single query.

Please guide me.

Thanks..

To quote the MySQL docs:

A SELECT statement may include a LIMIT
clause to restrict the number of rows
the server returns to the client. In
some cases, it is desirable to know
how many rows the statement would have
returned without the LIMIT, but
without running the statement again.
To obtain this row count, include a
SQL_CALC_FOUND_ROWS option in the
SELECT statement, and then invoke
FOUND_ROWS() afterward.
