MySQL查询从行中获取特定行
让我们首先创建一个表-
mysql> create table DemoTable1972 ( Section char(1), StudentName varchar(20) );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable1972 values('D','Chris');
mysql> insert into DemoTable1972 values('B','David');
mysql> insert into DemoTable1972 values('A','Mike');
mysql> insert into DemoTable1972 values('C','Carol');使用select语句显示表中的所有记录-
mysql> select * from DemoTable1972;
这将产生以下输出-
+---------+-------------+ | Section | StudentName | +---------+-------------+ | D | Chris | | B | David | | A | Mike | | C | Carol | +---------+-------------+ 4 rows in set (0.00 sec)
这是从行中获取特定行的查询-
mysql> select * from DemoTable1972 where Section > 'C' order by Section limit 2;
这将产生以下输出-
+---------+-------------+ | Section | StudentName | +---------+-------------+ | D | Chris | +---------+-------------+ 1 row in set (0.00 sec)
