How do I add a row in my power query editor?

[shahid_tanmoy]

Hi there, 
I have a query that is sourced from a database, I want to add a row to it that is just null or something else written in it. 

There is no way to practically do it that I can see since the table wasnt manually created by me.

Is there any syntax that can do this?

Hi @shahid_tanmoy,

you have multiple options.

You can manually enter data and create a new table then append it to your table.

Second option (what I do usually) i create a column with my delimiter string and split it into rows. If there is no any delimiter present, it will not split.

Hope this helps

Here is an example:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("HYzLEcAgCER74eygohGoxfFg/um/gYAHZhd4u73D3A8IsMUcKRGZzVjZRGwqssAIHc7rtrXFYtD6EkpxcV4LMi/seT876OpK2S1y83YPV0FVhTF+", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t, Column3 = _t, Column4 = _t, Column5 = _t]),
    #"Previous Step" = Table.TransformColumnTypes(Source,{
        {"Column1", type text}, {"Column2", type date}, {"Column3", type number}, {"Column4", Int64.Type}, {"Column5", Currency.Type}}),

    #"Add row of nulls" = 
        let 
            #"Null List" = List.Repeat({null}, Table.ColumnCount(#"Previous Step")),
            #"Null Row" = Record.FromList(#"Null List", Table.ColumnNames(#"Previous Step")),
            #"Add Null Row" = Table.FromRecords(Table.ToRecords(#"Previous Step") & {#"Null Row"})
           
        in 
            #"Add Null Row"

in
    #"Add row of nulls"

hi @shahid_tanmoy ,

I think you have to create a table with the row you would like to add using "Enter Data" in the same table structure as the table from the database.

Then append the tables together.

kindly note, this would lead to a table in "Dual" Storage mode.

Hi there, 

This doesnt work cause I cannot append the value as null

hi @shahid_tanmoy ,

see this example:

create two blank queries.

copy paste the following code in the advanced editor.

Ouput:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8nRRqDm0QME3Ma80LTG5pLQotQjIBQl5VBakFuVk5mUD2RioRilWJ1rJEKo0JLU4JxGbMgWIgoySkgIrff0SkDK95PxDC0AQJg02yQhqkl9mcXFiHlYb4cbkgdUAzckFGQMUB5tgDDUhKDUvsTSnBJt+7O7D6W6wsSZQY8Pyc8rycfkPma9LpMGmIJZCSH5lfgnWoAOHhr4jkS6NBQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}}),
    #"Split Column by Delimiter" = Table.SplitColumn(#"Changed Type", "Column1", Splitter.SplitTextByDelimiter("|", QuoteStyle.Csv), {"Column1.1", "Column1.2", "Column1.3", "Column1.4"}),
    #"Removed Columns" = Table.RemoveColumns(#"Split Column by Delimiter",{"Column1.4"}),
    #"Promoted Headers" = Table.PromoteHeaders(#"Removed Columns", [PromoteAllScalars=true]),
    #"Changed Type1" = Table.TransformColumnTypes(#"Promoted Headers",{{"ID ", Int64.Type}, {"  Manufacturer  ", type text}, {"  Hyperlink             ", type text}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type1", "Custom", each if Text.Contains([#"  Hyperlink             "], "http://") then 1 else 0),
    #"Renamed Columns" = Table.RenameColumns(#"Added Custom",{{"  Manufacturer  ", "Manufacturer"}, {"  Hyperlink             ", "Hyperlink"}, {"ID ", "ID"}}),
    #"Appended Query" = Table.Combine({#"Renamed Columns", TabletoAppend})
in
    #"Appended Query"

Table to Append

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlPSUYKi2FgA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [ID = _t, Manufacturer = _t, Hyperlink = _t, Custom = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"ID", Int64.Type}, {"Manufacturer", type text}, {"Hyperlink", type text}, {"Custom", type text}})
in
    #"Changed Type"
