MySQL 查询选择一行，该行包含一组以逗号分隔的数字?
mysqlmysqli database
您需要使用 FIND_IN_SET() 来实现此目的。让我们首先创建一个表 −
mysql> create table DemoTable ( CustomerId int NOT NULL AUTO_INCREMENT PRIMARY KEY, CustomerName varchar(20), CustomerAllProductPrice text ); Query OK, 0 rows affected (0.30 sec)
使用 insert 命令在表中插入一些记录。Here, we are inserting numbers separated by comma −
mysql> insert into DemoTable(CustomerName,CustomerAllProductPrice) values('Chris','245,345,678,90,45,56,78');
Query OK, 1 row affected (0.03 sec)
mysql> insert into DemoTable(CustomerName,CustomerAllProductPrice) values('Chris','98,99,90,56,77');
Query OK, 1 row affected (0.07 sec)
mysql> insert into DemoTable(CustomerName,CustomerAllProductPrice) values('David','1000,2000,4000,56000');
Query OK, 1 row affected (0.06 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 −
+------------+--------------+-------------------------+ | CustomerId | CustomerName | CustomerAllProductPrice | +------------+--------------+-------------------------+ | 1 | Chris | 245,345,678,90,45,56,78 | | 2 | Chris | 98,99,90,56,77 | | 3 | David | 1000,2000,4000,56000 | +------------+--------------+-------------------------+ 3 rows in set (0.00 sec)
以下查询用于选择包含相同数字的行，这些数字在列中用逗号分隔 −
mysql> select *from DemoTable where find_in_set('4000',CustomerAllProductPrice);
这将产生以下输出 −
+------------+--------------+-------------------------+ | CustomerId | CustomerName | CustomerAllProductPrice | +------------+--------------+-------------------------+ | 3 | David | 1000,2000,4000,56000 | +------------+--------------+-------------------------+ 1 row in set (0.14 sec)
