我已经创建了一个搜索功能。它可以通过全文找到地址，但如何通过地址的部分进行查询搜索？例如，完整地址为

paya lebar Road Blk27

，如何设置该地址，以便用户只需键入

paya

，它仍会显示

搜索表单

查看患者记录
选择：

使用类似“%$searchParam%”的

而不是Mysql中的=$searchParam
来搜索列是否具有特定的字符串用途
范例
SELECT * FROM table WHERE column LIKE '%somestring%'; 

就你而言，试试这个
$typed = $_POST['typed'];

然后像这样进行Mysql查询
$query = "select * from table where Address LIKE '%".$typed."%' ";

您忘记发布您的功能：查找患者（$select，$type）；
但我想您需要一个地址varchar字段的部分字符串查询，该字段如下所示：
select * from MyTable where myColumn like '%myPartialString%';

此类型的查询将返回其中包含“MyPartialString”的所有行。
在sql查询中使用LIKE%%
