無法在ORACLE 10G數據庫上進行PIVOT

Question

我正在嘗試使用oracle 10G。 屏幕截圖1是表中的實際數據。 我正在嘗試獲取屏幕截圖2之類的數據。請建議我PIVOT功能在10G中不起作用。 。

您可以使用conditional aggregation ：

SELECT ANALYST
    ,COUNT(CASE WHEN status = 'unchecked'   THEN 1 END) AS unchecked
    ,COUNT(CASE WHEN status = 'observation' THEN 1 END) AS observation
    ,COUNT(CASE WHEN status = 'supervisor'  THEN 1 END) AS supervisor
    ,COUNT(CASE WHEN status = 'pending'     THEN 1 END) AS pending
    ,COUNT(CASE WHEN status = 'closed'      THEN 1 END) AS closed
    ,COUNT(*) AS Grand_Tot
FROM tab
GROUP BY ANALYST
ORDER BY ANALYST;

我能知道如何將Grand_Tot列與該查詢求和嗎？我正在嘗試SUM（Grand_Tot），但由於無效標識符而出錯。

一種方法是使用子查詢：

SELECT sub.*, SUM(Grand_Tot) OVER() AS Sum_Grant_Tot
FROM (
    SELECT ANALYST
        ,COUNT(CASE WHEN status = 'unchecked'   THEN 1 END) AS unchecked
        ,COUNT(CASE WHEN status = 'observation' THEN 1 END) AS observation
        ,COUNT(CASE WHEN status = 'supervisor'  THEN 1 END) AS supervisor
        ,COUNT(CASE WHEN status = 'pending'     THEN 1 END) AS pending
        ,COUNT(CASE WHEN status = 'closed'      THEN 1 END) AS closed
        ,COUNT(*) AS Grand_Tot
    FROM tab
    GROUP BY ANALYST
) sub
ORDER BY ANALYST;
