Question

SELECT HCIS,ServiceDate,PrimeInsMnemonic,TIN,Amount,SUM(Amount) AS Total
FROM dbo.PbrChargeTransactions
WHERE HCIS = 'ASL'
AND ServiceDate Between'01/01/16' and '12/31/16'
AND PrimeInsMnemonic = 'MED'
AND TIN in ('460224598','46-0224598')
GROUP By HCIS
ORDER BY SUM(Amount)

我得到的错误：

Msg 8120，Level 16，State 1，Line 1 专栏＆＃39; dbo.PbrChargeTransactions.ServiceDate＆＃39;在选择列表中无效，因为它不包含在聚合函数或GROUP BY子句中。

我希望有人能够向我解释为什么这不起作用？

提前感谢您的帮助！

Answer 1

我认为这个消息很清楚。所有未聚合的列都应位于GROUP BY中。因此，请删除不使用的列：

SELECT HCIS, SUM(Amount) AS Total
FROM dbo.PbrChargeTransactions
WHERE HCIS = 'ASL' AND
      ServiceDate Between '2016-01-01' AND '2016-12-31' AND
      PrimeInsMnemonic = 'MED' AND
      TIN in ('460224598','46-0224598')
GROUP By HCIS
ORDER BY SUM(Amount)

Answer 2

如果它们不在聚合函数

中，您应该在Select语句中包含每个列以在Group By中重复

SELECT HCIS，ServiceDate，PrimeInsMnemonic，TIN，Amount，SUM（Amount）AS Total 来自dbo.PbrChargeTransactions HCIS =＆＃39; ASL＆＃39; AND ServiceDate在＆01; 01/01/16＆＃39;和＆＃39; 12/31/16＆＃39; AND PrimeInsMnemonic =＆＃39; MED＆＃39; AND TIN in（＆＃39; 460224598＆＃39;，＆＃39; 46-0224598＆＃39;） GROUP By HCIS，ServiceDate，PrimeInsMnemonic，TIN，Amount 按顺序订购（金额）

Answer 3

正如他们所说，你必须按照选择中的列输入组。

SELECT HCIS,ServiceDate,PrimeInsMnemonic,TIN,Amount,SUM(Amount) AS Total
FROM dbo.PbrChargeTransactions
WHERE HCIS = 'ASL'
AND ServiceDate Between'01/01/16' and '12/31/16'
AND PrimeInsMnemonic = 'MED'
AND TIN in ('460224598','46-0224598')
GROUP By HCIS,ServiceDate,PrimeInsMnemonic,TIN,Amount
ORDER BY SUM(Amount)
