hi all..
I think there is no way to count all the rows in a DB, using a single query. we can say.. desc table_name; (gives all the tables in the DB) and then get no of rows for each table..

I'm want ALL the rows from the WHOLE DATABASE not just one table. I could do a show tables and then loop through each one and perform the select count and add it up. But I'm hoping to find a better way. As for the script, simply read the mysqldump man page. It is in the examples near the bottom. In this case I needed to tweak it a bit by adding some quotes (-Q) and extenderd inserts etc. Otherwise I was gettting errors. But I ran the stock example on the man page for a couple of years now on 2 other databases.
