Good Morning,
I have some doubt in PowerQuery, i have a column with some numbers in the same line that I need to sum, how can I do it?
Example input
field 1 | field 2 | field 3
Planeacion 2,3,1 2,2,2
field 1 | field 2 | field 3
Planeacion 6 6

Thanks in advance

Answer 1

In powerquery you can do this
Click-select the columns with the commas
Right click, Replace values, and replace the comma with a plus ( , to +)
Click-select the same columns
Right click, Transform ... lowercase...
edit the resulting formula so that each time you see
Text.Lower, type text
you replace it with
each Expression.Evaluate(_), type number
Sample version for the two columns
let Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
#"Replaced Value" = Table.ReplaceValue(Source,",","+",Replacer.ReplaceText,{"field 2", "field 3"}),
#"Transform1" = Table.TransformColumns(#"Replaced Value",{{"field 2", each Expression.Evaluate(_), type number}, {"field 3", each Expression.Evaluate(_), type number}})
in #"Transform1"

Answer 2

If you create a function like this:
CREATE FUNCTION [dbo].[csv2list]
(
#p1 varchar(max)
)
RETURNS TABLE
AS
RETURN
(
WITH List as (
SELECT CAST (value AS varchar(max)) value
FROM STRING_SPLIT(SUBSTRING(#p1, 1, LEN(#p1)), ',')
)
SELECT value
FROM List
)
GO
Then you can do:
SELECT * FROM csv2list('2,3,1');
which will produce:
2
3
1
or to sum them, use:
select sum(cast(value as integer)) from csv2list('2,3,1');
