Get record count for all tables in MySQL database?

To get the count of all the records in MySQL tables, we can use TABLE_ROWS with aggregate function SUM. The syntax is as follows.
SELECT SUM(TABLE_ROWS)
   FROM INFORMATION_SCHEMA.TABLES
   WHERE TABLE_SCHEMA = 'yourDatabaseName';
Apply the above syntax in order to get the count of records for all tables. The query is as follows −
mysql> SELECT SUM(TABLE_ROWS)
   ->FROM INFORMATION_SCHEMA.TABLES
   ->WHERE TABLE_SCHEMA = 'business';
The following table returns the count of records.
+-----------------+
| SUM(TABLE_ROWS) |
+-----------------+
|             450 |
+-----------------+
1 row in set (13.54 sec)

To display the count of all records per table, use the following query −
mysql> SELECT table_name, table_rows
   ->FROM INFORMATION_SCHEMA.TABLES
   ->WHERE TABLE_SCHEMA = 'business';
The following is the output.
+------------------------------------------------------------------+------------+
