Question

Is there a way to get the count of rows in all tables in a MySQL database without running a SELECT count() on each table?

Answer 1

SELECT SUM(TABLE_ROWS)       FROM INFORMATION_SCHEMA.TABLES       WHERE TABLE_SCHEMA = '{your_db}'; 

Note from the docs though: For InnoDB tables, the row count is only a rough estimate used in SQL optimization. You’ll need to use COUNT(*) for exact counts (which is more expensive).
