如何在 SQL 的表格底部添加“總計”行？

Question

我有一個帶有總計列的 pivot 表，但我無法使用 SQL 在表底部制作總計行。這是我目前擁有的代碼：

SELECT
    Committee,
    COUNT(CASE WHEN status = 'Resume Review'    THEN 1 END) AS "Resume Review",
    COUNT(CASE WHEN status = 'Interviewing'     THEN 1 END) AS "Interviewing",
    COUNT(CASE WHEN status = 'Coding Challenge' THEN 1 END) AS "Coding Challenge",
    COUNT(*) AS Total
FROM EMPLOYEES
WHERE status IN ('Resume Review', 'Interviewing', 'Coding Challenge')
GROUP BY Committee;

這給了這個：

Committee   Resume Review   Interviewing    Take Home Challenge  Total 
UI/UX              3             2                  1              6
Finance            0             2                  2              4
Marketing          2             4                  1              7
          

我正在努力實現這一目標：

Committee   Resume Review   Interviewing    Take Home Challenge  Total 
UI/UX              3             2                  1              6
Finance            0             2                  2              4
Marketing          2             4                  1              7
Total              5             8                  4              17

您可以將“ROLLUP”添加到“GROUP BY”

SELECT
    CASE WHEN GROUPING(Committee) = 1 THEN 'Total' ELSE Committee END AS Committee,
    COUNT(CASE WHEN status = 'Resume Review'    THEN 1 END) AS "Resume Review",
    COUNT(CASE WHEN status = 'Interviewing'     THEN 1 END) AS "Interviewing",
    COUNT(CASE WHEN status = 'Coding Challenge' THEN 1 END) AS "Coding Challenge",
    COUNT(*) AS Total
FROM EMPLOYEES
WHERE status IN ('Resume Review', 'Interviewing', 'Coding Challenge')
GROUP BY Committee WITH ROLLUP
