如何在MySQL中搜索完全匹配的字符串列？

对于完全匹配的字符串，您需要使用LIKE运算符与通配符“%”-

select *from yourTableName where binary yourColumnName LIKE '%yourStringValue%';

让我们首先创建一个表-

mysql> create table DemoTable(
    Name varchar(20)
);
Query OK, 0 rows affected (1.93 sec)

使用插入命令在表中插入一些记录-

mysql> insert into DemoTable values('Chris');
Query OK, 1 row affected (1.11 sec)
mysql> insert into DemoTable values('John');
Query OK, 1 row affected (0.38 sec)
mysql> insert into DemoTable values('Adam');
Query OK, 1 row affected (1.19 sec)
mysql> insert into DemoTable values('JOHN');
Query OK, 1 row affected (0.60 sec)
mysql> insert into DemoTable values('ADAM');
Query OK, 1 row affected (0.43 sec)

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-

+-------+
| Name  |
+-------+
| Chris |
| John  |
| Adam  |
| JOHN  |
| ADAM  |
+-------+
5 rows in set (0.00 sec)

以下是在SQL中搜索完全匹配字符串列的查询-

mysql> select *from DemoTable where binary Name LIKE '%JOHN%';

这将产生以下输出-

+------+
| Name |
+------+
| JOHN |
+------+
1 row in set (0.09 sec)
