Number of rows in all tables

When you start to work on a project for a new customer, a good piece of information is how many tables does the database contain and how many rows are there in each table. Or maybe you don't have access to the production database and need to send a service request to the IT operations department to get information about the production database.
Then the query below will be useful to you.

SET @DatabaseName := 'test_db';

 WHERE t.TABLE_SCHEMA = @DatabaseName
