If column contains values from column in another table...

Hello

 

I would like a column that shows whether or not a column in Table2 contains values that are in Table1.

 

Table1 
ValueNew Column
ATRUE
BFALSE
CTRUE
DFALSE
E

TRUE

Table2
Value
A
C
E

 

Any Ideas?

 

Thanks!

Hi @bullius. If table 2 contains only unique values, you could relate the two tables on the Value column, and then use this formula for your New Column:

 

New Column = NOT(ISBLANK(RELATED(Table2[Value])))

 

You can also use the formula below, which will work with or without the relationship:

 

New Column = CALCULATE(COUNTROWS(Table2), FILTER(Table2, Table2[Value]=Table1[Value])) > 0

 

See this post for more information about how each method works.

I know KGrice's formula worked but it does seem a tad clunky... you could consider this as a slightly cleaner alternative (since the CONTAINS function exists exactly for this purpose):

 

Column = CONTAINS(Table2, Table2[Value], Table1[Value])

Thanks for the reply.

 

Table2 does not contain unique values...

Hi @bullius. The unique values piece only matters for creating a relationship. The second option I listed does not require unique values in either table. Were you able to get that one working?

Yes! The second one does the job. Thanks!

 but with this method, there has to be a relationship established between tables, right ?

Thanks, @jahida. I hadn't come across the CONTAINS function yet. I'll start using that instead.
