Hi,
I have two tables, a student table and a family table.
The student table is as follows, where Student ID is the primary Key.
Student ID | FamilyID |
1 | F001 |
2 | F002 |
3 | F003 |
4 | F004 |
5 | F001 |
The Family table is as follows, where many family members may belong to the same family ID..
FamilyID | Member | Phone |
F001 | Dad | 016-456-89876 |
F001 | Mom | |
F001 | Uncle | 676-876-98543 |
F002 | Dad | |
F002 | Mom | 412-562-88765 |
F003 | Dad | 416-542-86758 |
F004 | Dad | 416-592-86988 |
I need to find the list of pupils for whom any of the family member's phone no is missing. I'm using a direct query which makes creating Calculated columns and using calculate function difficult.
I need a final output of something similar to
Student ID | column |
1 | 1 |
2 | 1 |
3 | 0 |
4 | 0 |
5 | 1 |
Can anyone help me with this?
Thanks in advance.
Hi @Anonymous ,
Do your table have any relationship between them? If there is any relationship depeding on the type you may just need to use the columns and the filter pane.
Not having a realtionship try to create the following measure:
BlankContacts =
CALCULATE (
COUNT ( Family[FamilyID] ),
FILTER (
ALL ( Family ),
Family[FamilyID] = SELECTEDVALUE ( Students[FamilyID] )
&& Family[Phone] = BLANK ()
)
) + 0
Now if you create a table visual and add the ID and the measure you get the following result:
