如何检查特定 MySQL 数据库中表的大小?

Just like we have checked the size of the MySQL database, we can also check the size of the tables in a specific database. It can be done as follows -

mysql> SELECT
    -> table_name AS "Table",
    -> round(((data_length + index_length) / 1024 / 1024), 2) as SIZE
    -> FROM information_schema.TABLES
    -> WHERE table_schema = "SAMPLE"
    -> ORDER BY SIZE;
+-------------+-------+
| Table       | SIZE  |
+-------------+-------+
| employee    | 0.02  |
| student     | 0.02  |
| new_student | 0.02  |
+-------------+-------+
3 rows in set (0.00 sec)
Copy after login

The output here gives the Example size of the three tables in the database.
