Problem with comparisson

Hi folks,

 

I want to compare strings from columns from two tables.

If the same string exists in both tables I want to output 1 if not 0.

I created a new column in Table Diti with the function:

 

if [Zusammengefügt] = Timesheet_std[Zusammengefügt2] then 1 else 0

 

The syntax is fine, but I get 0 for all entries even for the ones which exist in both columns.

Which lead me to the concluison, that maybe the linking of my tables (Diti and Timesheet_std), which are connected through the columns Zusammengefügt and Zusammengefügt2 is not working properly. But when I go into the visuals, everything works fine both tables update if I filter them by something, so the connection should work.

Which leads to my concluison, that the power query function I wrote has a mistake in it, which I wasn't able to find.

If anyone can suggest a solution or a diffrent approach to solve this problem - I would be very happy.

Thanks in advance

Philipp

Hi @ACC_Entwickler1 ,

 

If case-sensitive, try:

= if List.Contains(#"Timesheet_std"[Zusammengefügt2],[Zusammengefügt]) then 1 else 0

Otherwise:

if List.Contains(List.Transform(#"Timesheet_std"[Zusammengefügt2], each Text.Upper(_)), Text.Upper([Zusammengefügt])) then 1 else 0

hi @ACC_Entwickler1 ,

 

if you are comparing strings, ensure they are the same format ( clean, trim and upper might help, else use Comparer.OrdinalIgnoreCase - PowerQuery M | Microsoft Learn for case insensitive comparisons).

 

if this doesn't work,

 

please provide the pbix / same input and output data removing sensitive information if possible.

 

thanks
