使用 MySQL 将表结果显示到临时表中?
我们首先创建一个表 −
mysql> create table DemoTable1 (Id int,Name varchar(100)); Query OK, 0 rows affected (0.89 sec)
使用 insert 命令在表中插入一些记录 −
mysql> insert into DemoTable1 values(100,'John'); Query OK, 1 row affected (0.19 sec) mysql> insert into DemoTable1 values(110,'Chris'); Query OK, 1 row affected (0.16 sec) mysql> insert into DemoTable1 values(120,'Robert'); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable1 values(130,'David'); Query OK, 1 row affected (0.14 sec)
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)
以下是将表结果显示到临时表中的查询 −
mysql> create temporary table DemoTable2 select *from DemoTable1; Query OK, 4 rows affected (0.01 sec) Records: 4 Duplicates: 0 Warnings: 0
让我们查看临时表的表记录 −
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)
