IF condition

Hello,

 

could anyone tell me what is wrong with the following statement:

 

Column = IF Query[CR] = NaN then 0 else Query1[CR]

 

Thank you,

Ekaterina

= NaN won't work either in Power Query.

 

Working example query:

 

let
    Source = Table.FromList({1,#nan,2}, Splitter.SplitByNothing(), {"CR"}, null, ExtraValues.Error),
    #"Added Custom" = Table.AddColumn(Source, "Custom", each if Number.IsNaN([CR]) then 0 else [CR])
in
    #"Added Custom"

Hi @Ekaterina

 

Please replace "IF" with "if" (Power Query is case sensitive)

and Query[CR] with [CR].

 

 

@Anonymous well I select Query1[CR] as Power BI advices me in the bar so it knows from which query am I selecting CR. I have tried to replaced IF for if and tried both without Query1 and with it, but it returns me an error anyway. It says that ''the syntax for ´then´ is incorrect. (DAX(IF (Query1[CR] = NaN then 0 else Query1[CR]))).''

@Ekaterina

 

@MarcelBeug's reply should work for Power Query.

For DAX you can try

Column = IF(Query[CR]="NaN","0",Query[CR])

or

Column 2 = IF(ISBLANK(Query[CR]),"0",Query[CR])

Your Query seems to be a DAX Query..

 

@MarcelBeugand I posted you Power Query solutions (I have to admit, that only @MarcelBeug solution works, as I've overlooked the NaN issue....)..
