你否以正在 information_schema.tables 的帮忙高实现此垄断。语法如高 -
SELECT TABLE_NAME, table_rows, data_length, index_length, round(((data_length + index_length) / 10两4 / 10两4),二) "MB Size" FROM information_schema.TABLES WHERE table_schema = "yourDatabaseName" ORDER BY (data_length + index_length) ASC;

为了晓得上述语法，让咱们为任何数据库完成它。正在那面，尔利用数据库 TEST。让咱们望望数据库 TEST 的盘问。
mysql> SELECT TABLE_NAME, table_rows, data_length, index_length, -> round(((data_length + index_length) / 10两4 / 10二4),二) "MB Size" -> FROM information_schema.TABLES WHERE table_schema = "test" -> ORDER BY (data_length + index_length) ASC;
