How to count the number of tables in a MySQL database?
To count the total number of tables, use the concept of count(*) with table_schema. First, to check how many tables are present in our database "business", we need to use the 'show' command.
mysql> show tables;
The following is the output that displays all the tables in the database "business".

In the above, we have 132 tables in the database business.
To check the count of tables.
mysql> SELECT count(*) AS TOTALNUMBEROFTABLES -> FROM INFORMATION_SCHEMA.TABLES -> WHERE TABLE_SCHEMA = 'business';
The following output gives the count of all the tables.
+---------------------+ | TOTALNUMBEROFTABLES | +---------------------+ | 132 | +---------------------+ 1 row in set (0.01 sec)
