Compare if a value is in another table and vice versa

[Anonymous]

Hello everyone,

I have two tables:
Table1

COD_1

001

002

003

Table2

COD_2

001

002

008

I would like to compare the COD column of Table1 with the COD column of Table2. Each value of these two columns is never repeated.
So I would like to create a third table that shows the CODs, and two columns named Table1 and Table2. Each of these columns informing whether the respective COD is in table 1 or table 2, or in both tables.
The table shoud be something like this:

COD_newTable	Table1	Table2
001	Yes	Yes
002	Yes	Yes
003	Yes	No
008	No	Yes

Can someone help me, please?

HI @Anonymous,

You can use union function to merge these records and use 'in' operator to check if they existed in specific table records:

Table =
SUMMARIZE (
    SELECTCOLUMNS ( UNION ( ALL ( T1[COD_1] ), ALL ( T2[COD_2] ) ), "COD", [COD_1] ),
    [COD],
    "T1", [COD] IN VALUES ( T1[COD_1] ),
    "T2", [COD] IN VALUES ( T2[COD_2] )
)

you can also do it in power query, see attached.

Hi @Anonymous 

create a calculated table

Table = 
ADDCOLUMNS(
DISTINCT(
    UNION(
        SELECTCOLUMNS(Table1,"COD",Table1[COD_1]),
        SELECTCOLUMNS(Table2,"COD",Table2[COD_2])
    )
),
"Table1", IF(CALCULATE(COUNTROWS(Table1),Table1[COD_1]=EARLIER([COD])) > 0, "Yes", "No"),
"Table2", IF(CALCULATE(COUNTROWS(Table2),Table2[COD_2]=EARLIER([COD])) > 0, "Yes", "No")
)

then add put its fields to visual
