让我们首先创建一个表-
mysql> create table DemoTable ( Name varchar(40), Score int );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values('Chris Brown',78); mysql> insert into DemoTable values('John Doe',88); mysql> insert into DemoTable values('Carol Taylor',98); mysql> insert into DemoTable values('David Miller',80);
使用select语句显示表中的所有记录-
mysql> select *from DemoTable;
这将产生以下输出-
+--------------+-------+ | Name | Score | +--------------+-------+ | Chris Brown | 78 | | John Doe | 88 | | Carol Taylor | 98 | | David Miller | 80 | +--------------+-------+ 4 rows in set (0.00 sec)
以下是获取单元格特定值的查询-
mysql> select Score from DemoTable where Name='Carol Taylor';
这将产生以下输出-
+-------+ | Score | +-------+ | 98 | +-------+ 1 row in set (0.00 sec)
