MySQL 如何搜索逗号分隔值的表格？

要在逗号分隔值的表格中进行搜索，可以使用LIKE运算符。让我们首先创建一个表格 –

mysql> create table DemoTable675(Value text);
Query OK, 0 rows affected (0.55 sec)

使用插入命令将一些记录插入表格中 –

mysql> insert into DemoTable675 values('10,56,49484,93993,211,4594');
Query OK, 1 row affected (0.28 sec)
mysql> insert into DemoTable675 values('4,7,1,10,90,23');
Query OK, 1 row affected (0.41 sec)
mysql> insert into DemoTable675 values('90,854,56,89,10');
Query OK, 1 row affected (0.21 sec)
mysql> insert into DemoTable675 values('11,22,344,67,89');
Query OK, 1 row affected (0.10 sec)

使用选择语句从表格中显示所有记录 –

mysql> select *from DemoTable675;

这将产生以下输出 –

+----------------------------+
| Value                      |
+----------------------------+
| 10,56,49484,93993,211,4594 |
| 4,7,1,10,90,23             |
| 90,854,56,89,10            |
| 11,22,344,67,89            |
+----------------------------+
4 rows in set (0.00 sec)

以下是在逗号分隔值的表格中搜索的查询语句 –

mysql> select *from DemoTable675
WHERE Value LIKE '10,%'
OR Value LIKE '%,10'
OR Value LIKE '%,10,%'
OR Value= '10';

这将产生以下输出 –

+----------------------------+
| Value                      |
+----------------------------+
| 10,56,49484,93993,211,4594 |
| 4,7,1,10,90,23             |
| 90,854,56,89,10            |
+----------------------------+
3 rows in set (0.00 sec)
