Hi there,
I've a a large number of reports running off a dataset connecting to directly to SQL Server. I've had to rename several fields to more useful names in the Query ediitor.
When I refresh these reports I get the following error below.
Is there a way of renaming fields so my reports will pick up these newly named fields dynamically?
Solved! Go to Solution.
Few ways to go about this. Since it's coming from sql I think it would be safe to assume that the order of the columns would be the same. Going with that idea:
= Table.ToList(Source)
(Source as table, Index as list, NewNames as list) => let #"Index of Old Columns" = List.Transform(Index, each Table.ColumnNames( Source ){_} ), ZippedList = List.Zip( {#"Index of Old Columns",NewNames}), #"Rename Columns" = Table.RenameColumns(Source, ZippedList) in #"Rename Columns"
Then you can use that function in your table:
= fnRenameColumns(Source, {0..(List.Count(NewColumnNames)-1)},NewColumnNames)
Could use a few more steps to get rid of that List.Count, but this works just fine.
