按表名對 MySQL 展示表進行排序?
你可以用 ORDER BY 子句按 INFORMATION_SCHEMA.TABLES 中的 table_name 屬性進行排序。透過 ASC 或 DESC 來按升序或降序排序。語法如下 -
SELECT table_name FROM information_schema.tables WHERE table_type = 'BASE TABLE' AND table_schema='yourDatabaseName' ORDER BY table_name DESC;
使用名為 sample 的資料庫並設定一些表。首先,我們將展示所有表,然後我們將應用按表名排序。顯示所有表的查詢如下 -
mysql> show tables;
以下是輸出 -
+--------------------------+ | 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詢。現在,讓我們用 ORDER BY 子句按降序顯示所有表 -
mysql> SELECT table_name -> FROM information_schema.tables -> WHERE table_type = 'BASE TABLE' AND table_schema='sample' -> ORDER BY table_name DESC;
以下是輸出 -
+--------------------------+ | TABLE_NAME | +--------------------------+ | yourtable | | sumofeverydistinct | | notequaloperator | | newlinedemo | | mytable | | insertrecordprevent | | insertrecord_selecttable | | insert_prevent | | blobsizedemo | +--------------------------+ 9 rows in set (0.00 sec)
