要从记录中查找匹配项,请使用MySQL IN()
。让我们首先创建一个表-
mysql> create table DemoTable
(
Id int,
FirstName varchar(20),
Gender ENUM('Male','Female')
);
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values(1,'Chris','Male');
mysql> insert into DemoTable values(10,'Emma','Female');
mysql> insert into DemoTable values(9,'Emma','Male');
mysql> insert into DemoTable values(11,'Isabella','Female');
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-
+------+-----------+--------+
| Id | FirstName | Gender |
+------+-----------+--------+
| 1 | Chris | Male |
| 10 | Emma | Female |
| 9 | Emma | Male |
| 11 | Isabella | Female |
+------+-----------+--------+
4 rows in set (0.00 sec)
以下是查找与ID 1和11匹配并获取记录的查询-
mysql> select *from DemoTable where Id IN(1,11);
这将产生以下输出-
+------+-----------+--------+
| Id | FirstName | Gender |
+------+-----------+--------+
| 1 | Chris | Male |
| 11 | Isabella | Female |
+------+-----------+--------+
2 rows in set (0.00 sec)
