mysql中单个表的多个结果

Question

我的数据库中有一个包含列的表：

Lead_id INT(11) PRIMARY KEY NOT NULL
user_id INT(11)
lead_status ENUM('active','win','loss')

以下示例数据：

Lead_id     user_id     lead_status
   1          45         active
   2          31         win
   3          11         loss
   4          45         win
   5          11         active
   6          45         loss

我需要查询上表得到如下输出：

user_id      total_leads      active     win     loss
   45             3              1        1        1
   31             1              0        1        0
   11             2              1        0        1

我打算以图形方式表示输出表中的数据。任何帮助将不胜感激。

Answer 1

试试这个：

SELECT
    user_id,
    COUNT(*) AS total_leads,
    SUM(lead_status = 'active') AS active,
    SUM(lead_status = 'win') AS win,
    SUM(lead_status = 'loss') AS loss
FROM your_table
GROUP BY user_id
