如何检查特定 MySQL 数据库中表的大小？

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  |
+-------------+-------+
