为此,请使用AS select语句。让我们首先创建一个表-
mysql> create table DemoTable1 ( Score int );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable1 values(89); mysql> insert into DemoTable1 values(98); mysql> insert into DemoTable1 values(91);
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-
+-------+ | Score | +-------+ | 89 | | 98 | | 91 | +-------+ 3 rows in set (0.00 sec)
以下是将一列的值复制到新表的查询-
mysql> create table DemoTable2( StudentScore int )AS select Score AS StudentScore from DemoTable1; Records: 3 Duplicates: 0 Warnings: 0
让我们再次检查表记录-
mysql> select StudentScore from DemoTable2;
这将产生以下输出-
+--------------+ | StudentScore | +--------------+ | 89 | | 98 | | 91 | +--------------+ 3 rows in set (0.00 sec)
