如何使用 MySQL 檢視為數字新增分隔符?
我們首先建立一個表 −
mysql> create table DemoTable ( StudentId int ); Query OK, 0 rows affected (0.62 sec)
使用 insert 命令向表中插入一些記錄 −
mysql> insert into DemoTable values(343898456); Query OK, 1 row affected (0.20 sec) mysql> insert into DemoTable values(222333444); Query OK, 1 row affected (0.22 sec)
以下查詢使用 select 語句從表中顯示所有記錄 −
mysql> select *from DemoTable;
這會產生以下輸出 −
+-----------+ | StudentId | +-----------+ | 343898456 | | 222333444 | +-----------+ 2 rows in set (0.00 sec)
下面是建立檢視的查詢 −
mysql> create view myView_DemoTable as select format(StudentId, 0) AS `StudentId` from DemoTable; Query OK, 0 rows affected (0.18 sec) Let us check the records of view table: mysql> select *from myView_DemoTable;
這會產生以下輸出 −
+-------------+ | StudentId | +-------------+ | 343,898,456 | | 222,333,444 | +-------------+ 2 rows in set (0.04 sec)
