如何使用MySQL视图向数字添加分隔符？
让我们首先创建一个表-
mysql> create table DemoTable ( StudentId int );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values(343898456); mysql> insert into DemoTable values(222333444);
以下是使用select语句显示表中所有记录的查询-
mysql> select *from DemoTable;
这将产生以下输出-
+-----------+ | StudentId | +-----------+ | 343898456 | | 222333444 | +-----------+ 2 rows in set (0.00 sec)
这是创建视图的查询-
mysql> create view myView_DemoTable as select format(StudentId, 0) AS `StudentId` from DemoTable; Let us check the records of view table: mysql> select *from myView_DemoTable;
这将产生以下输出-
+-------------+ | StudentId | +-------------+ | 343,898,456 | | 222,333,444 | +-------------+ 2 rows in set (0.04 sec)
