<div>{{row.inquiry_details | concatFilter('assessment_all_value')}}</div>解释一下这段vue的语法

这段 Vue 代码中，{{}} 表示插值语法，用于将表达式的结果渲染到模板中。row 是一个数据对象，inquiry_details 是其中一个属性。concatFilter 是一个过滤器，用于将 inquiry_details 属性的值进行处理后返回。这里的 'assessment_all_value' 是 concatFilter 的参数，表示要进行拼接的字符串。整个代码的作用是将 inquiry_details 属性的值与 'assessment_all_value' 拼接后渲染到模板中的 div 元素中。

使用uniapp框架，从一个list 数组, list每一项字段为inquiry_id, inqruiy_details=>{[0]:{'inquiry_detail'=>111,'assetment_all_value'=>1000}},通过搜索inquiry_id，定位到该条数据

可以使用uniapp提供的数组方法`find`来实现，具体代码如下：

let list = [
  { inquiry_id: 1, inquiry_details: [{ inquiry_detail: 111, assessment_all_value: 1000 }] },
  { inquiry_id: 2, inquiry_details: [{ inquiry_detail: 222, assessment_all_value: 2000 }] },
  { inquiry_id: 3, inquiry_details: [{ inquiry_detail: 333, assessment_all_value: 3000 }] }
];

let inquiryId = 2; // 假设要搜索的inquiry_id为2

let targetData = list.find(item => item.inquiry_id === inquiryId);

console.log(targetData);

其中，`find`方法会返回数组中满足条件的第一项数据，如果找不到则返回`undefined`。上述代码会输出：

{ inquiry_id: 2, inquiry_details: [{ inquiry_detail: 222, assessment_all_value: 2000 }] }

如果要获取该条数据的`inquiry_details`字段，可以继续使用数组索引，例如：

let inquiryDetails = targetData.inquiry_details[0];

console.log(inquiryDetails);

会输出：

{ inquiry_detail: 222, assessment_all_value: 2000 }

看起来 SQL 查询语句中有一个问题，'usage' 是 MySQL 中的保留关键字，不能用作列名。为了解决这个问题，可以将 'usage' 重命名为其他名称，例如 'property_usage'。修改后的 SQL 查询语句如下：
