使用MySQL IN()显示多个选定的行
让我们首先创建一个表-
mysql> create table DemoTable1045 ( Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, FirstName varchar(100) )AUTO_INCREMENT=100;
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable1045(FirstName) values('John');
mysql> insert into DemoTable1045(FirstName) values('Chris');
mysql> insert into DemoTable1045(FirstName) values('Robert');
mysql> insert into DemoTable1045(FirstName) values('Mike');
mysql> insert into DemoTable1045(FirstName) values('Adam');使用select语句显示表中的所有记录-
mysql> select *from DemoTable1045;
这将产生以下输出-
+-----+-----------+ | Id | FirstName | +-----+-----------+ | 100 | John | | 101 | Chris | | 102 | Robert | | 103 | Mike | | 104 | Adam | +-----+-----------+ 5 rows in set (0.00 sec)
以下是MySQL查询以显示多个选定的行-
mysql> select *from DemoTable1045 tbl where(tbl.Id, tbl.FirstName) IN ((101, 'Chris'), (102, 'Robert'), (104,'Adam'));
这将产生以下输出-
+-----+-----------+ | Id | FirstName | +-----+-----------+ | 101 | Chris | | 102 | Robert | | 104 | Adam | +-----+-----------+ 3 rows in set (0.05 sec)
