【英文标题】：SQL - return only values where its a negative sum

【问题描述】：

下午好 - 抱歉这个愚蠢的问题，我似乎无法弄清楚如何引入 WHERE 语句来进行计算以仅返回负 REV_DIFF 值（（SUM(PREVIOUS_REVENUE) - SUM(CURRENT_REVENUE)) REV_DIFF）。 请原谅格式 - 仍在学习... 谢谢！

WITH X AS

  SELECT
    1 TYPE, I.NAME COMPANY, C.CLIENT_ID, C.NAME CLIENT_NAME, T.BILL_NUMBER CURRENT_FB, T.WEIGHT CURRENT_WEIGHT,
    (T.CHARGES + T.XCHARGES) * CASE WHEN T.TOTAL_CHARGES = 0 THEN 0 ELSE (T.FUNCTIONAL_AMT / T.TOTAL_CHARGES) END CURRENT_REVENUE,
    NULL PREVIOUS_FB, NULL PREVIOUS_WEIGHT, NULL PREVIOUS_REVENUE

    AND T.EXTRA_STOPS <> 'Child'
    AND T.BILL_NUMBER NOT IN ('0', 'NA')

  (SUM(PREVIOUS_REVENUE) - SUM(CURRENT_REVENUE)) REV_DIFF
FROM X
GROUP BY COMPANY

ORDER BY REV_DIFF

【参考方案1】：

您可以使用HAING 子句和GROUP BY 来过滤具有负值的记录。在GROUP BY 之后使用这个。

HAVING (SUM(PREVIOUS_REVENUE) - SUM(CURRENT_REVENUE))) < 0

太棒了！起初我无法让它工作，然后我意识到我需要将此条件添加到上下查询中。非常感谢！
