select for renaming columns

Open femtotrader opened this issue 2 years ago • 0 comments

Hello,

following discussion https://gitlab.com/ExpandingMan/Parquet2.jl/-/issues/46 I wonder if select couldn't provide an "alias SQL like" mechanism for renaming columns.

What about something like

ds |> TableOperations.select(:time => :timestamp, :open, :high, :low, :close, :volume) |> TimeArray

Kind regards
