SQL to DAX

Two tables, Table A has User/Event/EventDate. Table B has User/InteractionDate.   I would use the following SQL Statement to get a one to many table;       Select A.User, A.Event, A.EventDate,...

    Hi Anonymous ,

     

    Here I create a sample to have a test.

    A:

    B:

    By Power Query:

    let
    Source = Table.NestedJoin(A, {"User"}, B, {"User"}, "B", JoinKind.LeftOuter),
    #"Expanded B" = Table.ExpandTableColumn(Source, "B", {"User", "InteractionDate"}, {"B.User", "B.InteractionDate"}),
    #"Filtered Rows" = Table.SelectRows(#"Expanded B", each [B.InteractionDate] >= [EventDate] and [B.InteractionDate]<=Date.AddDays([EventDate],30))
in
    #"Filtered Rows"

     Result is as below.

     

    By Dax:

    Dax Table = 
VAR _ADD = ADDCOLUMNS(A,"B.User",RELATED(B[User]),"B.InteractionDate",RELATED(B[InteractionDate]))
VAR _FILTER = FILTER(_ADD,[B.InteractionDate]>=[EventDate]&&[B.InteractionDate]<=[EventDate]+30)
RETURN
_FILTER

    Result is as below.

Hi Anonymous ,

A:

B:

By Power Query:

let
    Source = Table.NestedJoin(A, {"User"}, B, {"User"}, "B", JoinKind.LeftOuter),
    #"Expanded B" = Table.ExpandTableColumn(Source, "B", {"User", "InteractionDate"}, {"B.User", "B.InteractionDate"}),
    #"Filtered Rows" = Table.SelectRows(#"Expanded B", each [B.InteractionDate] >= [EventDate] and [B.InteractionDate]<=Date.AddDays([EventDate],30))
in
    #"Filtered Rows"

 Result is as below.

 

By Dax:

Dax Table = 
VAR _ADD = ADDCOLUMNS(A,"B.User",RELATED(B[User]),"B.InteractionDate",RELATED(B[InteractionDate]))
VAR _FILTER = FILTER(_ADD,[B.InteractionDate]>=[EventDate]&&[B.InteractionDate]<=[EventDate]+30)
RETURN
_FILTER

Result is as below.
