Question

当我尝试从许多文件扩展表时，我遇到了一个问题，我丢失了一些值。到目前为止，我发现问题是在查询遇到一个空表时开始的。我试图过滤掉空表，但问题仍然存在。知道什么是问题以及如何解决吗？

查询： let Source = Folder.Files("X:\Operations\tutaj\SLA MIAD"), #"Lowercased Text" = Table.TransformColumns(Source,{{"Extension", Text.Lower, type text}}), #"Filtered Rows" = Table.SelectRows(#"Lowercased Text", each Text.Contains([Extension], "xlsx")), #"Filtered Rows1" = Table.SelectRows(#"Filtered Rows", each Text.Contains([Name], "NCR") or Text.Contains([Name], "Printec") or Text.Contains([Name], "PTL")), #"Filtered Rows2" = Table.SelectRows(#"Filtered Rows1", each Text.Contains([Name], "2018")), #"Removed Other Columns" = Table.SelectColumns(#"Filtered Rows2",{"Content"}), #"Added Custom" = Table.AddColumn(#"Removed Other Columns", "Custom", each Excel.Workbook([Content])), #"Expanded Custom" = Table.ExpandTableColumn(#"Added Custom", "Custom", {"Name", "Data", "Item", "Kind", "Hidden"}, {"Name", "Data", "Item", "Kind", "Hidden"}), #"Filtered Rows3" = Table.SelectRows(#"Expanded Custom", each ([Kind] = "Sheet")), #"Filtered Rows4" = Table.SelectRows(#"Filtered Rows3", each Text.Contains([Name], "SLA report")), #"Removed Columns" = Table.RemoveColumns(#"Filtered Rows4",{"Name", "Item", "Kind", "Hidden"}), #"Removed Errors" = Table.RemoveRowsWithErrors(#"Removed Columns", {"Content"}), #"Invoked Custom Function" = Table.AddColumn(#"Removed Errors", "TestFunction", each FileQuery([Data])), #"Added Custom1" = Table.AddColumn(#"Invoked Custom Function", "Custom", each Table.IsEmpty([TestFunction])), #"Filtered Rows6" = Table.SelectRows(#"Added Custom1", each ([Custom] = false)), #"Expanded TestFunction" = Table.ExpandTableColumn(#"Filtered Rows6", "TestFunction", {"Order ID", "ATM", "City", "Country", "CIT/Vault", "Service", "SLACategory", "Condition", "Serv Acc Mon", "Serv Acc Sat", "Serv Acc Sun", "Status", "Reason", "Description", "Created(CET)", "SLA Target Date(CET)", "Closed(CET)", "Age", "Contractual Reaction Time", "Overdue By absolute", "Overdue By Srv.Hrs", "On Time", "Charged call", "Reference ID", "Reference priority", "Comments", "SLA Category"}, {"Order ID", "ATM", "City", "Country", "CIT/Vault", "Service", "SLACategory", "Condition", "Serv Acc Mon", "Serv Acc Sat", "Serv Acc Sun", "Status", "Reason", "Description", "Created(CET)", "SLA Target Date(CET)", "Closed(CET)", "Age", "Contractual Reaction Time", "Overdue By absolute", "Overdue By Srv.Hrs", "On Time", "Charged call", "Reference ID", "Reference priority", "Comments", "SLA Category"}), #"Removed Other Columns1" = Table.SelectColumns(#"Expanded TestFunction",{"Order ID", "ATM", "City", "Country", "CIT/Vault", "Service", "Condition", "Reason", "Status", "Description", "Created(CET)", "SLA Target Date(CET)", "Closed(CET)", "Overdue By absolute", "Overdue By Srv.Hrs", "On Time"}), #"Changed Type" = Table.TransformColumnTypes(#"Removed Other Columns1",{{"Created(CET)", type datetime}, {"SLA Target Date(CET)", type datetime}, {"Closed(CET)", type datetime}}), #"Added Custom2" = Table.AddColumn(#"Changed Type", "Age", each [#"Closed(CET)"]-[#"Created(CET)"]), #"Changed Type1" = Table.TransformColumnTypes(#"Added Custom2",{{"Age", type duration}}), #"Filtered Rows5" = Table.SelectRows(#"Changed Type1", each [Order ID] <> null and [Order ID] <> "") in #"Filtered Rows5"

我想，问题的根源可能在于您的自定义函数 FileQuery 。

Answer 2

我认为表（要扩展）中的标头与实际扩展的标头之间存在一些差异。

您已经展开了SLACategory和Order ID（在屏幕截图的上半部分），但是它们可能分别是SLA Category和OrderId（在下半部分）屏幕截图）。请注意间距和大小写的差异。

当您指定要扩展的标题List（在下面的{和}之间）时：

#"Expanded TestFunction" = Table.ExpandTableColumn(#"Filtered Rows6", "TestFunction", {"Order ID", "ATM", "City", "Country", "CIT/Vault", "Service", "SLACategory", "Condition", "Serv Acc Mon", "Serv Acc Sat", "Serv Acc Sun", "Status", "Reason", "Description", "Created(CET)", "SLA Target Date(CET)", "Closed(CET)", "Age", "Contractual Reaction Time", "Overdue By absolute", "Overdue By Srv.Hrs", "On Time", "Charged call", "Reference ID", "Reference priority", "Comments", "SLA Category"}, {"Order ID", "ATM", "City", "Country", "CIT/Vault", "Service", "SLACategory", "Condition", "Serv Acc Mon", "Serv Acc Sat", "Serv Acc Sun", "Status", "Reason", "Description", "Created(CET)", "SLA Target Date(CET)", "Closed(CET)", "Age", "Contractual Reaction Time", "Overdue By absolute", "Overdue By Srv.Hrs", "On Time", "Charged call", "Reference ID", "Reference priority", "Comments", "SLA Category"}),

我想你要么

对标题本身进行硬编码（根据大小写和空格的不同）
或动态扩展它们，而不基于某些硬编码列表。

要动态扩展列，您必须执行以下操作：

#"Expanded TestFunction" = Table.ExpandTableColumn(#"Filtered Rows6", "TestFunction", {"Order ID", "ATM", "City", "Country", "CIT/Vault", "Service", "SLACategory", "Condition", "Serv Acc Mon", "Serv Acc Sat", "Serv Acc Sun", "Status", "Reason", "Description", "Created(CET)", "SLA Target Date(CET)", "Closed(CET)", "Age", "Contractual Reaction Time", "Overdue By absolute", "Overdue By Srv.Hrs", "On Time", "Charged call", "Reference ID", "Reference priority", "Comments", "SLA Category"}, {"Order ID", "ATM", "City", "Country", "CIT/Vault", "Service", "SLACategory", "Condition", "Serv Acc Mon", "Serv Acc Sat", "Serv Acc Sun", "Status", "Reason", "Description", "Created(CET)", "SLA Target Date(CET)", "Closed(CET)", "Age", "Contractual Reaction Time", "Overdue By absolute", "Overdue By Srv.Hrs", "On Time", "Charged call", "Reference ID", "Reference priority", "Comments", "SLA Category"}),

具有：

allHeaders = List.Combine(List.Transform(#"Filtered Rows6"[TestFunction], Table.ColumnNames)),
headersToExpand = List.Distinct(allHeaders),
#"Expanded TestFunction" = Table.ExpandTableColumn(#"Filtered Rows6", "TestFunction", headersToExpand),

（您需要单击查询编辑器左上方的“高级编辑器”，然后在其中替换代码。）

扩展表时查询缺少的值
