无法在ORACLE 10G数据库上进行PIVOT

Question

我正在尝试使用oracle 10G。 屏幕截图1是表中的实际数据。 我正在尝试获取屏幕截图2之类的数据。请建议我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;

编辑：

我能知道如何将Grand_Tot列与该查询求和吗？我正在尝试SUM（Grand_Tot），但由于无效标识符而出错。

一种方法是使用子查询：

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;
