MYSQL / SQL計數百分比查詢

Question

是）我有的

$query =
  "SELECT
      status_type,
      COUNT(*) as count,
      kpi_type,
      COUNT('kpi') * 100.00 as percentage
  FROM
      main
  GROUP BY
      status_type DESC;";

我得到了什么。

[{"Status":"SOLD","KPI_Percentage":"1400","KPI":"SALE","Status_Count":"14"}]

這是我的JSON數組

 $JSON_output[] = array('Status'         => $row['pin_status'],
                           'KPI'            => $row['kpi_type'],
                           'KPI_Percentage'         => $row['percent'],
                           'Status_Count'           => $row['count'],);}}

我想做什么......

[{"status":"value","kpi":"value","count":"12""percentage":"%32.42"}]

我正在嘗試計算status_type ，並顯示status_type ，我正在嘗試顯示kpi_type ，並計算kpi_type與其他kpi_type s相比所以如果我有3個已售出，2個潛在客戶和5個潛在客戶，則會顯示：“LEAD： 20％出售30％前景50％“

我正在尋求什么答案......

$query = //// THE CORRECT GOODS TO INSERT INTO THIS QUERY ////
  "SELECT
      status_type,
      COUNT(*) as count,
      kpi_type,
      COUNT('kpi') * 100.00 as percentage
  FROM
      main
  GROUP BY
      status_type DESC;";

如果您有任何疑問，請告訴我。

Answer 1

您可以嘗試以下查詢：

    SELECT status_type, kpi_type, Count(*), 
    ((Count(*)  * 100.0)/ (select Count(*) FROM main)) AS Percentage
    FROM main
    GROUP BY status_type, kpi_type
    ORDER BY status_type, kpi_type

補充評論。

Answer 2

$query = "SELECT status_type, kpi_type, Count(*) as count,((Count(*)  * 100.0)/ (select Count(*) FROM main)) AS Percentage
                    FROM main
                    GROUP BY status_type, kpi_type
                    ORDER BY status_type, kpi_type";

Answer 3

我現在沒有MySql在你面前，但你需要得到所有記錄的總數，然后按狀態和KPI做一組像這樣（這是粗略的語法 - 也許它會讓你更接近）：

select @Total:=Count(*) from InputTable;
select `Status`, `Kpi`, Count(*) as Status_Count, ((Count(*)  * 100.0)/ @Total) AS KPI_Percentage
from InputTable 
group by `Status`, `Kpi`
order by `Status`, `KPI`;

查詢結果

        Invalid query: You have an error in your SQL syntax; check the manual
     that corresponds to your MySQL server version for the right syntax to use
     near 'select [status_type], [kpi_type], Count(), ((Count() * 100.0)/ @Total) 
    AS Perc' at line 3 Whole query: select @Total =(select Count() from main_pins) 
    select [status_type], [kpi_type], Count(), ((Count(*) * 100.0)/ @Total) 
    AS Percentage from main_pins group by [status_type], [kpi_type] order by [status_type],
 [kpi_type]

Answer 4

在修補Raveenanigam的答案之后能夠得到答案。 感謝大家的幫助和贊成，以獲得一些關注。

$query = "SELECT status_type, kpi_type, Count(*) as count,((Count(*)  * 100.0)/ (select Count(*) FROM main)) AS Percentage
                    FROM main
                    GROUP BY status_type, kpi_type
                    ORDER BY status_type, kpi_type";

結果給出。

[{"status_type":"Hot Lead","KPI":"Lead","Percentage":"0.31596","Count":"2"}
