Can we get total number of rows in a MySQL database?

To get the total number of rows in a MySQL database, you can use aggregate function SUM() along with inbuilt column TABLE_ROWS from INFORMATION_SCHEMA.TABLES.

The syntax is as follows−

SELECT SUM(TABLE_ROWS)
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA = database();

Let’s say we are using the database with the name ‘sample’.

Now we will get the total number of rows in a MySQL database−

mysql> SELECT SUM(TABLE_ROWS)
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA = database();

This will produce the following output−

+-----------------+
| SUM(TABLE_ROWS) |
+-----------------+
| 2043            |
+-----------------+
1 row in set (22.11 sec)
