在SQL中使用数据透视功能之前我得到了这个记录结构
使用Pivot后:
这是我的SQL查询
SELECT
FromHubID,
FromHubName,
ToHubID,
SUM([1 - 100]) AS [1 - 100],
SUM([101 - 250]) AS [101 - 250],
SUM([251 - 500]) AS [251 - 500],
SUM([501 - 1000]) AS [501 - 1000]
FROM
(SELECT
AccountGroupID,
FromHubID,
FromHubName,
ToHubID,
T_ID,
[1 - 100],
[101 - 250],
[251 - 500],
[501 - 1000]
FROM
(
SELECT
AG.AccountGroupID
,AG.FromHubID
,FH.Hub_Name AS FromHubName
,AG.ToHubID
,AG.T_ID
,CONVERT(VARCHAR , [MinWeight]) + ' - ' + CONVERT(VARCHAR ,[MaxWeight]) AS slot
,[Rate]
FROM
[CourierDev].[dbo].[AccountGroupQuotation] AS AG
INNER JOIN HubMaster AS FH ON FH.Hub_Id = AG.FromHubID
WHERE
accountgroupid = 1
)Sourcetable
PIVOT
(
Sum(Rate)
FOR slot IN ( [1 - 100],
[101 - 250],
[251 - 500],
[501 - 1000] )
)AS AGQuotationList
)AS tbl
GROUP BY
FromHubID,
FromHubName,
ToHubID
我的问题是插槽中的字段数和它的值不在这里修复我在数据库语法中添加静态字段并选择语法 对于这个特定的记录,但是如何管理插槽的值和插槽值的计数何时不能解决?
FOR示例 如果只有2种类型的记录[1 - 100],[101 - 250]那么我只需要两个支点

您可以使用动态SQL:
DECLARE @columns nvarchar(max),
@sql nvarchar(max)
SELECT @columns = COALESCE(@columns,'') +','+QUOTENAME(slot)
FROM #YourTable
GROUP BY slot
SELECT @sql = N'
SELECT FromHubID,
FromHubName,
ToHubID
'+@columns+'
FROM #YourTable
PIVOT (
SUM(Rate) FOR slot IN ('+STUFF(@columns,1,1,'')+')
) as pvt'
EXEC sp_executesql @sql
输出:
FromHubID FromHubName ToHubID 1 - 100 101 - 250 251 - 500 501 - 1000
