Select all columns starting with

[Anonymous]

Hi,

I want to select all the columns starting with a certain name. In this case: alarm. There are 200 columns starting with this -> alarm[001], alarm[002] etc. 

I now have: 
Select * FROM table

where column_name LIKE 'alarm%' 

It also isn't possible to say select alarm[001] , alarm[002] etc. Because the [ cause some kind of error. The error they give states that alarm can't be resolved. so it doens't take the [001] in account.

But that doesn't work. Anybody an idea?

Hey,

You can use the following Power M code to filter by rows beginning with "alarm".

    #"Filtered Rows" = Table.SelectRows(Source, each Text.StartsWith([ColumnName], "alarm"))

Kind regards,

Alex

I created a small illustrative example

Please see attached file's query editor for steps

First determine the Columns to Select using

=List.Select(Table.ColumnNames(#"Changed Type"),each Text.Contains(_,"alarm"))

 Then we can use

= Table.SelectColumns(#"Changed Type",ColumnsToSelect)
