MySQL 如何在列之间搜索

使用BETWEEN子句在列之间进行搜索。首先创建一个表 –

mysql> create table DemoTable
   (
   Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   Score1 int,
   Score2 int
   );
Query OK, 0 rows affected (0.78 sec)

使用插入命令在表中插入一些记录 –

mysql> insert into DemoTable(Score1,Score2) values(45,65);
Query OK, 1 row affected (0.26 sec)
mysql> insert into DemoTable(Score1,Score2) values(450,680);
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable(Score1,Score2) values(800,900);
Query OK, 1 row affected (0.17 sec)

使用select语句显示表中的所有记录 –

mysql> select *from DemoTable;
