Question

这两个查询，返回多个记录，那么有没有解决方法从另一个结果中减去一个结果的每一行数据？

QUERY1：

SELECT COUNT(*) As AbhidayNotPaidSansthan
 FROM PanjikaranMaster GROUP BY Zila

QUERY2：

SELECT COUNT(*) as anps FROM AbhidayMaster,PanjikaranMaster
    WHERE PanjikaranMaster.OfficeRegId=AbhidayMaster.OfficeRegId AND
    AbhidayMaster.DipositDate Between ('2012-09-19') AND ('2012-09-24')
GROUP BY PanjikaranMaster.Zila

尝试使用此查询，它将解决您的问题：

SELECT ISNULL(a.cnt,0) -  ISNULL(b.cnt,0) AS CNT,a.Zila
FROM
    (SELECT Zila,COUNT(*) as cnt As AbhidayNotPaidSansthan
    FROM PanjikaranMaster GROUP BY Zila) a
    LEFT JOIN 
    (SELECT Zila,COUNT(*) as cnt FROM AbhidayMaster,PanjikaranMaster
    WHERE PanjikaranMaster.OfficeRegId=AbhidayMaster.OfficeRegId AND
    AbhidayMaster.DipositDate Between ('2012-09-19') AND ('2012-09-24')
    GROUP BY PanjikaranMaster.Zila) b 
    ON a.Zila = b.Zila

我在 SQLFIDDLE

中进行了类似的测试
