R.id.battery_percent

R.id.battery_percent通常是在Android应用开发中用于标识电池百分比视图资源ID的一个常量。这个ID代表了一个视图控件，比如TextView或者其他可以显示电量百分比的UI元素。当你需要在XML布局文件中引用并设置这个电池状态信息的地方，你可以使用`@+id/battery_percent`这样的语法来引用这个资源ID。

例如，在XML布局文件中可能会看到类似这样的一行：

<TextView
    android:id="@+id/battery_percent"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="0%" />

然后在Java或Kotlin代码中，你可以通过findViewById()获取这个控件，并动态更新电池电量：

View batteryPercentView = findViewById(R.id.battery_percent);
batteryPercentView.setText(getBatteryLevelPercentage());

以下是修改后的SQL语句，主要是为了使语句更加易读和易懂：

SELECT 
    pr.PRODUCT_ID, 
    pr.PRODUCT_NAME, 
    pr.ORIGINAL_PRICE, 
    pr.ONLINE_PRICE,

    address.CREATE_TIME, 
    users.nickname
FROM 
    t_product pr
    LEFT JOIN t_order ord ON ord.PRODUCT_ID = pr.ID
    LEFT JOIN (
        SELECT label, `value` 
        FROM system_dict_data 
        WHERE dict_type = 'COMMERCE_TYPE'
    ) AS dict ON dict.`value` = pr.COMMERCE_TYPE 
    LEFT JOIN (
        SELECT label, `value` 
        FROM system_dict_data 
        WHERE dict_type = 'trade_after_sample_type'
    ) AS date ON date.`value` = ord.SEND_FLG
    LEFT JOIN t_apply_pro pro ON pro.PRODUCT_ID = pr.ID
    LEFT JOIN t_apply_pro_user_address address ON address.t_apply_pro_id = pro.ID
    LEFT JOIN system_users users ON users.id = pro.OPERATE_USER_ID 
WHERE 
    users.id = '1'

修改后的SQL语句对语句进行了格式化和缩进，使得语句更加易读和易懂。同时，还对表名和字段名进行了简化，以减少语句的长度，使其更加简洁。

这段 MySQL 存储过程中出现了语法错误，具体来说是在以下这行代码：

GROUP BY  gst.job_number；

末尾多了一个分号，应该改为：

GROUP BY  gst.job_number;
