Question

我已在以下图片中显示的数据库中保存了逗号分隔的不同功能： enter image description here 当我选择像这样的单一功能时

SELECT rt.*, rb.*, rf.*, rs.*
FROM business rt
INNER JOIN business_company_info rb
ON rt.id=rb.business_id
INNER JOIN business_attributes rf
ON rt.id=rf.business_id
INNER JOIN business_basic_info rs
ON rt.id=rs.business_id
WHERE business_keyword LIKE '%3000%' AND features LIKE '%feature3%' and
status= 0 ORDER BY rt.id DESC

从数据库中获取数据，但是当我有许多功能时，它无法搜索。这是我对所选多项功能的查询

SELECT rt.*, rb.*, rf.*, rs.*
FROM business rt
INNER JOIN business_company_info rb
ON rt.id=rb.business_id
INNER JOIN business_attributes rf
ON rt.id=rf.business_id
INNER JOIN business_basic_info rs
ON rt.id=rs.business_id
WHERE business_keyword LIKE '%3000%' AND features LIKE'%feature3,feature2,feature4%' and
status= 0 ORDER BY rt.id DESC

这是我的代码。

if(isset($_POST['advance_search']) && !empty($_POST['advance_search']) && ((isset($_POST['area']) && !empty($_POST['area']))  || 
                            (isset($_POST['salary']) && !empty($_POST['salary'])) || (isset($_POST['industry']) && !empty($_POST['industry'])) || (isset($_POST['jobtype']) && !empty($_POST['jobtype']))

任何帮助将不胜感激。谢谢

Answer 1

如果要查找所有功能的匹配项，则WHERE子句的第一部分应为：

WHERE business_keyword LIKE '%3000%' AND (features LIKE '%feature3%' AND features LIKE '%feature2%' AND features LIKE '%feature4%') .....

如果您想要匹配任何功能，请使用

WHERE business_keyword LIKE '%3000%' AND (features LIKE '%feature3%' OR features LIKE '%feature2%' OR features LIKE '%feature4%') .....

Answer 2

如果您的数据不是静态的并且正在从数据库中提取，请尝试使用

WHERE business_keyword LIKE'％3000％'AND（功能LIKE'％feature％'）.....

试试这个。

Answer 3

您可以展开$功能并将其存储到数组中。这样的事情。

try {
     if (helper != null) {
             helper.flagEndAsync();
     }
     helper.launchPurchaseFlow(.....)
}catch(IllegalStateException e){
     e.printStackTrace();
}

希望它有所帮助。
