Solved: Re: SelectColumn in Dataflow

bboy0009 · ‎12-27-2022

Hi guys,

I'm using dataflow to do all data transformations. I would like to create a table by retreiving data from a column of another table (A) so I tried table.selectcolumn but I think it is not available in a dataflow because firtsly there is not suggestion of the formula and secondly I wrote the whole instruction and it's wrong.

To optimize the performance, I want to avoid to take all data of the table A and then remove all useless column. Do you have any idea how could I do that ?

Thank you in advance !

Hello - select columns is available in dataflows. I've included a sample below. Please replace the table and column names with those from your data.

Table.SelectColumns(table,{"Column1","Column2"})
