Wordpress如何通过用户ID AND type_operation从MySQL表的列中回显SUM

Posted 2023-02-01

我在wordpress数据库中有帐户资金表。这样的结构；

Id           user_id         fund_user        type_operation
-----------------------------------------------------------
1             1379               100              admin_op
2             1565               500              admin_op
3             1379              -50               pay
4             1379               200              admin_op
5             1616              -150              pay

并且在我的Wordpress页面中，我想显示以下内容：

已登录用户仅type_operation中的admin_op，仅获得总计positive fund_user值。

我有这个；

global $wpdb; 
$result_good = $wpdb->get_results("Select sum(fund_user) as good_points from wp_ywf_user_fund_log where type_operation='admin_op'");

        $haha= "Total Points for Good =".$result_good['good_points'];
        echo $haha;
        return $haha;

但是没有结果，我不能为我的特定查询编辑它。

对于当前用户，我如何在该表中获取和回显特定type_operation的Fund_user价值的Total？感谢您的所有答复。

答案

对我来说很好...

CREATE TABLE wp_ywf_user_fund_log
(id SERIAL PRIMARY KEY
,user_id INT NOT NULL
,fund_user INT NOT NULL
,type_operation VARCHAR(12) NOT NULL
);

INSERT INTO wp_ywf_user_fund_log VALUES
(1           ,  1379,               100     ,        'admin_op'),
(2            , 1565 ,              500      ,        'admin_op'),
(3            , 1379 ,             -50       ,        'pay'),
(4            , 1379 ,              200      ,        'admin_op'),
(5            , 1616 ,             -150      ,        'pay');

Select sum(fund_user) as good_points from wp_ywf_user_fund_log where type_operation='admin_op';

+-------------+
| good_points |
+-------------+
|         800 |
+-------------+

也许您正在追捕...

Select user_id
     , sum(fund_user) as good_points 
  from wp_ywf_user_fund_log 
 where type_operation = 'admin_op' 
 GROUP 
    BY user_id;
+---------+-------------+
| user_id | good_points |
+---------+-------------+
|    1379 |         300 |
|    1565 |         500 |
+---------+-------------+

...或...

Select sum(fund_user) as good_points 
  from wp_ywf_user_fund_log 
 where type_operation = 'admin_op'
   and user_id = 1379;


  +-------------+
  | good_points |
  +-------------+
  |         300 |
  +-------------+
