当数据不存在时，包括Null或$ 0

Question

pa.fdpayadjamount表有几个不同的类别（存款，付款等）。我想要做的是汇总所有存款和存款不存在的地方，使金额自动输入$ 0或null。有人可以帮我这个吗？谢谢！

SELECT ca.fdorgunit AS Facility
, pt.fdmedrecnum AS Account
, ca.fddos AS DOS
, Cast(iv.fdinnetdeposit/100.0 as decimal(10,2)) AS [Deposit Required]
, Cast(Sum(pa.fdpayadjamount)/100.0 as decimal(10,2)) AS Deposit
FROM OPENQUERY (VISION, 'SELECT * FROM de.tbinsverification') AS iv
LEFT JOIN OPENQUERY (VISION, 'SELECT * FROM ci.tbcase') AS ca
ON iv.fdcase = ca.id
JOIN OPENQUERY (VISION, 'SELECT * FROM de.tbpatient') AS pt
ON pt.id = ca.fdpatient
LEFT JOIN OPENQUERY (VISION, 'SELECT * FROM ar.tbpayadjmaster') AS pa
ON pa.fdpatient = pt.id
WHERE iv.fdinnetdeposit is not Null AND iv.fdinnetdeposit <> '0' AND ca.fdcasestatus = 'Performed' AND pa.fdledgercodetype = 'Deposit'
GROUP BY ca.fdorgunit, ca.fddos, iv.fdinnetdeposit, pt.fdmedrecnum

Answer 1

也许你只需要在第五行添加ISNULL（）函数就好了。

, Cast(ISNULL(Sum(pa.fdpayadjamount),0)/100.0 as decimal(10,2)) AS Deposit

Answer 2

您可以尝试使用此代码来处理总和。

isnull（Cast（sum（pa.fdpayadjamount）/100.0 as decimal（10,2）），0）AS Deposit

Answer 3

这实际上解决了我自己的问题：

, Sum(Case When pa.fddescription = 'Deposit' Then Cast(pa.fdpayadjamount/100.0 as decimal(10,2)) Else 0 END) AS Deposit
