Hi,

I need some assistance to write a formula to compare two columns in different tables in Power BI

Hi @Pooja_Mishra ,
Do you mean like this?

excepttable = except(values('Table2'[Country]),values('Table1'[Country]))

This shows those countries in table 2 that are not in table 1.

Let me know if you have any questions.

If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos 👍are nice too.

Hi @Nathaniel_C ,

Thanks for your help. I got my resolution, but this query also works:

excepttable = except(Table2,Table1)

I got this as output:

It resolved my query. Thanks for your help again!!!

If you would share your pbix, or dummy up some values in Excel both for current and expected data. Please copy and paste them into your post, rather than doing a picture, we may be able to help you.

Hi Nathaniel,

Thanks for your response. Here, is the dummy data:

Table 1:

Prefix	Country	Count
A	ABC	2
B	FHG	4
C	KJL	5
D	SGH	6
E	YUI	4
F	KJH	9

Table 2:

Prefix	Country	Count
A	ABC	2
B	FHG	4
C	KJL	5
G	BNM	3
D	SGH	6
H	JKL	8
E	YUI	4
F	KJH	9

I need to write a formula to compare two columns (Country) from the above 2 tables in Power BI

Hi @Pooja_Mishra , not sure what you mean when you say compare two columns.  Do you mean how many more countries are in table 2?
If so, try this:

More Countries in T2 compared to T1 =
VAR _t1Country =
    COUNT ( Table1[Country] )
VAR _t2Country =
    COUNT ( Table2[Country] )
RETURN
    _t2Country - _t1Country

Let me know if you have any questions.
