按表名对 MySQL 展示表进行排序?
你可以用 ORDER BY 子句按 INFORMATION_SCHEMA.TABLES 中的 table_name 属性进行排序。通过 ASC 或 DESC 来按升序或降序排序。语法如下 -
SELECT table_name FROM information_schema.tables WHERE table_type = 'BASE TABLE' AND table_schema='yourDatabaseName' ORDER BY table_name DESC;
使用名为 sample 的数据库并设置一些表。首先,我们将展示所有表,然后我们将应用按表名排序。显示所有表的查询如下 -
mysql> show tables;
以下是输出 -
+--------------------------+ | Tables_in_sample | +--------------------------+ | blobsizedemo | | insert_prevent | | insertrecord_selecttable | | insertrecordprevent | | mytable | | newlinedemo | | notequaloperator | | sumofeverydistinct | | yourtable | +--------------------------+ 9 rows in set (0.00 sec)
以下是按表名排序的查询。现在,让我们用 ORDER BY 子句按降序显示所有表 -
mysql> SELECT table_name -> FROM information_schema.tables -> WHERE table_type = 'BASE TABLE' AND table_schema='sample' -> ORDER BY table_name DESC;
以下是输出 -
+--------------------------+ | TABLE_NAME | +--------------------------+ | yourtable | | sumofeverydistinct | | notequaloperator | | newlinedemo | | mytable | | insertrecordprevent | | insertrecord_selecttable | | insert_prevent | | blobsizedemo | +--------------------------+ 9 rows in set (0.00 sec)
