MySQL tables statistics (size, engine, no. of rows etc.)
MySQL provides statistical data for users to get more knowledge about the tables in databases. The command to get this useful information is "mysql table status".
SHOW TABLE STATUS [{FROM | IN} db_name] [LIKE 'pattern' | WHERE expr]
Assuming you have selected a database and run the following command:
SHOW TABLE STATUS LIKE '%'
MySQL returns information about all the tables in the selected database. For more info about what MySQL returns, click here. If you want to see information about a particular table in a particular database then you run the command as follows:
SHOW TABLE STATUS FROM <database name> LIKE '<table name>'
Replace <database name> with your database name and <table name> with the table name.
