在MySQL中使用COLLATE查找确切的字符串值？
让我们首先创建一个-
mysql> create table DemoTable1620 -> ( -> Subject varchar(20) -> );
使用insert在表中插入一些记录-
mysql> insert into DemoTable1620 values('mysql');
mysql> insert into DemoTable1620 values('MySql');
mysql> insert into DemoTable1620 values('mYSQL');
mysql> insert into DemoTable1620 values('MySQL');
mysql> insert into DemoTable1620 values('MYSQL');使用选择显示表中的所有记录-
mysql> select * from DemoTable1620;
这将产生以下输出-
+---------+ | Subject | +---------+ | mysql | | MySql | | mYSQL | | MySQL | | MYSQL | +---------+ 5 rows in set (0.00 sec)
以下是在MySQL中搜索确切字符串值的查询-
mysql> select * from DemoTable1620 where Subject collate utf8_bin = 'MySQL';
这将产生以下输出-
+---------+ | Subject | +---------+ | MySQL | +---------+ 1 row in set (0.00 sec)
