我能使用MySQL查询在逗号分隔的记录中搜索特定数字吗?

可以使用MySQL FIND_IN_SET()搜索特定数字。首先创建一个表 −

mysql> create table DemoTable
(
   ListOfNumbers varchar(100)
);
Query OK, 0 rows affected (1.24 sec)

使用插入命令将一些记录插入表中 −

mysql> insert into DemoTable values('784,746,894,344');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable values('456,322,333,456');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable values('654,785,678,456');
Query OK, 1 row affected (0.47 sec)
mysql> insert into DemoTable values('123,676,847,785');
Query OK, 1 row affected (0.34 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 −

+-----------------+
| ListOfNumbers   |
+-----------------+
| 784,746,894,344 |
| 456,322,333,456 |
| 654,785,678,456 |
| 123,676,847,785 |
+-----------------+
4 rows in set (0.00 sec)

以下是在记录中搜索特定数字的查询语句 −

mysql> select *from DemoTable where find_in_set('456',ListOfNumbers);

这将产生以下输出 −

+-----------------+
| ListOfNumbers   |
+-----------------+
| 456,322,333,456 |
| 654,785,678,456 |
+-----------------+
2 rows in set (0.28 sec)
