是的，您可以使用 MySQL FIND_IN_SET() 搜索特定数字。让我们首先创建一个表 −
mysql> create table DemoTable ( ListOfNumbers varchar(100) ); Query OK, 0 rows affected (1.24 sec)
使用 insert 插入命令在表中插入一些记录 −
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 −
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)
