Question

我有这个查询从表中选择不同的TCName值：

SELECT DISTINCT(TCName) 
FROM [dbo].[TCDetails]

这是另一个将数据汇总到表中的查询：

SELECT 
    sum(BS.BLDOS) as BLDOS,
    sum(BS.CollectedAmount) as CollectedAmount
FROM [Customer] C 
INNER JOIN [dbo].[BillingStatus] BS 
    ON BS.CustomerID = C.CustomerID 
INNER JOIN [dbo].[TCDetails] TC 
    ON TC.CustomerID = BS.CustomerID

我想编写一个查询，以便能够将所有TC的数据总和打印到单个表

中

我试试这个，但它不起作用

SELECT 
    sum(BS.BLDOS) as BLDOS,
    sum(BS.CollectedAmount) as CollectedAmount
FROM [Customer] C 
INNER JOIN [dbo].[BillingStatus] BS 
    ON BS.CustomerID = C.CustomerID 
INNER JOIN [dbo].[TCDetails] TC 
    ON TC.CustomerID = BS.CustomerID 
WHERE TCName in 
    (
    Select distinct
        (TCName)
    FROM [dbo].[TCDetails]
    )

我想打印它像

  TCName  | sum(BS.BLDOS) | sum(BS.CollectedAmount)
  xyz     | 23456         |  6755
  tyu     | 34556         |  567898
  bnv     | 21467         |  345

如果您想在输出中添加多行，则需要group by

  SELECT TCName, sum(BS.BLDOS) as BLDOS, sum(BS.CollectedAmount) as CollectedAmount
  FROM [Customer] C INNER JOIN
       [dbo].[BillingStatus] BS
       ON BS.CustomerID = C.CustomerID INNER JOIN
       [dbo].[TCDetails] TC 
       ON TC.CustomerID = BS.CustomerID
  WHERE TCName in (Select distinct(TCName) FROM [dbo].[TCDetails])
  GROUP BY TCName;

我想编写一个查询来将所有TC的数据总和打印到单个表中
