无法在 ORACLE 10G 数据库上进行 PIVOT

Question

我正在尝试使用 oracle 10G 进行调整。屏幕截图 1 是 table 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。 .

Answer 1

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;

Can i know how to SUM the Grand_Tot Column along with that query i was trying SUM(Grand_Tot) but getting error as invalid identifier.

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;
