使用MySQL IN()获得带下划线的某些列值
让我们首先创建一个表-
create table DemoTable1363
-> (
-> StudentId varchar(20)
-> );使用插入命令在表中插入一些记录-
insert into DemoTable1363 values('901');
insert into DemoTable1363 values('702');
insert into DemoTable1363 values('901_John_Doe');
insert into DemoTable1363 values('1001_Carol_Taylor');使用select语句显示表中的所有记录-
select * from DemoTable1363;
这将产生以下输出-
+-------------------+ | StudentId | +-------------------+ | 901 | | 702 | | 901_John_Doe | | 1001_Carol_Taylor | +-------------------+ 4 rows in set (0.00 sec)
这是实现IN()的MySQL查询-
select * from DemoTable1363 where StudentId IN('702','1001');这将产生以下输出-
+-----------+ | StudentId | +-----------+ | 702 | +-----------+ 1 row in set (0.00 sec)
