Select all columns starting with

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)
