用MySQL将表的结果显示到临时表中？
让我们首先创建一个表-
mysql> create table DemoTable1 (Id int,Name varchar(100));
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable1 values(100,'John'); mysql> insert into DemoTable1 values(110,'Chris'); mysql> insert into DemoTable1 values(120,'Robert'); mysql> insert into DemoTable1 values(130,'David');
使用select语句显示表中的所有记录-
mysql> select *from DemoTable1;
这将产生以下输出-
+------+--------+ | Id | Name | +------+--------+ | 100 | John | | 110 | Chris | | 120 | Robert | | 130 | David | +------+--------+ 4 rows in set (0.00 sec)
以下是将表的结果显示到临时表中的查询-
mysql> create temporary table DemoTable2 select *from DemoTable1; Records: 4 Duplicates: 0 Warnings: 0
让我们检查临时表的表记录-
mysql> select *from DemoTable2;
这将产生以下输出-
+------+--------+ | Id | Name | +------+--------+ | 100 | John | | 110 | Chris | | 120 | Robert | | 130 | David | +------+--------+ 4 rows in set (0.00 sec)
