DAX help needed

Hi Power Users,

 

I'm still learning powerbi. I need help in getting below sql query write in power bi using dax. 

 

select sum(Monthcount), sum(Monthcount)/12 from (select indexid, count(distinct MonthID) as MonthCount, Count(Distinct indexId) as Indexid_count, count(distinct MonthID)/6 as ABC from Table-1
Innerjoin Table-2 on Table-1. MonthID= Table-2.MonthID

Where monthyear between '202001' and '202010'
group by indexid

 

I need this query to write using DAX. 

 

Thanks

    Anonymous , You can have measures like this

     

    sumx(values('Table-1'[indexid]), distinctcount('Table-1'[indexid]))
    sumx(values('Table-1'[indexid]), distinctcount('Table-1'[MonthID]))
    sumx(values('Table-1'[indexid]), distinctcount('Table-1'[MonthID]))/12

     

    Both Tables should join on MonthID in power BI and where you can take filter in the slicer

     

    You can refer my Dax vs SQL series, if that can help https://www.youtube.com/watch?v=WlvQ_SGy4iA&list=PLPaNVDMhUXGZNyKU0PgG2g3P0c6CPjMnj

    Hi Anonymous ,

     

    Would you please try something like:

     

    sum(Monthcount)/12 =
VAR a =
    SUMMARIZE (
        FILTER (
            NATURALINNERJOIN ( Table - 2, Table - 1 ),
            'Table-2'[monthyear] >= 202001
                && 'Table-2'[monthyear] <= 202010
        ),
        'Table-2'[indexid],
        "MonthCount", DISTINCTCOUNT ( 'Table-2'[MonthID] ),
        "ABC", DISTINCTCOUNT ( 'Table-2'[MonthID] ) / 6
    )
RETURN
    SUMX ( a, [MonthCount] ) / 12

sum(Monthcount) =  VAR a =
    SUMMARIZE (
        FILTER (
            NATURALINNERJOIN ( Table - 2, Table - 1 ),
            'Table-2'[monthyear] >= 202001
                && 'Table-2'[monthyear] <= 202010
        ),
        'Table-2'[indexid],
        "MonthCount", DISTINCTCOUNT ( 'Table-2'[MonthID] ),
        "ABC", DISTINCTCOUNT ( 'Table-2'[MonthID] ) / 6
    )
RETURN
    SUMX ( a, [MonthCount] )
