Left join in SQL transfer to Dax Messure

Hello together,

 

my SQL is:

 

select Tab2.Comment

from Tab1

leftjoin Tab2 ON (Tab1.ID = Tab2.ID )

 

As we use the direct query so a merge in Table is not possible. We need this join as a messure because in the Datamodel the connection allways filter only ID with comments. But the IDs without comments are filltered out.

    Hi Anonymous ,

     

    You should be able use use left outer join when merging in Query Editor. It is a drop down under "Join Kind" when you open the merge queries window. 

     

    If however you wanted a DAX, you can use the following:

    LOOKUPVALUE('Tab2'[comments],'Tab2'[id],SELECTEDVALUE(Tab1[id]))

     However, this will still require that there is a relationship between the two tables on the id. Again this would return null for whenever there is no match. 

     

    I hope this helps!

     

    Thanks!
