      I m quite new the qlik sence. I have tow associated tables A and B which have a common field Email

      In a measure I want to do a count only on the emails of table A . I want the equivalent of this sql statement Select A.Email.

      When I set the association between the tow table i can't distinguish between the emails of table A and the emails of table B

          If there is no way to distinguish which table they came from then you have a couple of choices.


          Change the field name in one of the tables so that they don't associate.  Then you can create separate tables displaying each tables data. Of course they will not automatically associate if you also need to do other things with the data.


          Or you could create a new field in the load with a value of A or B that would then allow you to filter in the app for emails from each table.  This would give you both the association as well as the ability to filter the tables.

            add a flag in each table:



            load email,



            'Table1' as Flag1


            from source1;




            load email,



            'Table2' as Flag2


            from source2;


            Now, if u want to count the email of table1 :



            Now, if u want to count the email of table2 :
