 ## 简要说明
 
 现有系统联动的本质是数据集查询参数“示例值”的替换， 现在联动有两种。<br>
+除下文介绍的示例外，还可去数据集、体验地址去查看示例。<br>
 
 - 表单联动 <br>
   目前支持的有下拉框、时间筛选器。<br>

 自定义JS，这里的JS是java的scriptengine执行的，支持ES5的写法。

 }
 ```
 
+- 示例二 <br>
+  不传参则查询全部
+
+```sql
+// sql可以这么写
+SELECT DATE_FORMAT(create_time, '%Y-%m-%d') create_time, sum(nums) sum_nums
+FROM aj_report_city ${city_name}
+group by create_time;
+```

+```js
+// 不传参则查询全部
+function verification(data) {
+    // 获取示例值

+        return ''
+    }
+    data = 'where city_name = "' + data + '" '
+    return data;
+}
+```
+
+**注：** 当前V1.0.0版本示例值是不可为空的，所以实际使用可能会麻烦点

 ### 数据转换
 
 数据转换是在执行完 sql 之后进行的数据清洗操作。
