要查看MySQL数据库的大小,可以使用以下SQL查询语句:

```sqlSELECT table_schema AS 'Database', SUM AS 'Total Size ', SUM AS 'Data Size ', SUM AS 'Index Size ', SUM AS 'Free Space ', ROUND / 1024 / 1024, 2qwe2 AS 'Total Size ', ROUND / 1024 / 1024, 2qwe2 AS 'Data Size ', ROUND / 1024 / 1024, 2qwe2 AS 'Index Size ', ROUND / 1024 / 1024, 2qwe2 AS 'Free Space 'FROM information_schema.TABLESGROUP BY table_schema;```

这个查询会返回每个数据库的总大小、数据大小、索引大小和空闲空间,单位分别为字节和兆字节。你可以通过修改 `GROUP BY` 子句来只查看特定数据库的大小。例如,如果你想查看名为 `my_database` 的数据库的大小,可以将查询修改为:

```sqlSELECT table_schema AS 'Database', SUM AS 'Total Size ', SUM AS 'Data Size ', SUM AS 'Index Size ', SUM AS 'Free Space ', ROUND / 1024 / 1024, 2qwe2 AS 'Total Size ', ROUND / 1024 / 1024, 2qwe2 AS 'Data Size ', ROUND / 1024 / 1024, 2qwe2 AS 'Index Size ', ROUND / 1024 / 1024, 2qwe2 AS 'Free Space 'FROM information_schema.TABLESWHERE table_schema = 'my_database'GROUP BY table_schema;```

请根据你的具体需求修改查询语句。
