How to compare two columns with each row of two columns.

C1	C2	new C1
A	1	0
B	F	B
C	H	C
D	A	D
1	8	0

From the above table. compare the C1 and C2 , if they are equal then particular compared value in C1 must be made 0. for example In C1 I have A and in C2 I have A then C1 contains A made to 0.Is it doable in alteryx.

It can be done but its much trickier. Here is a way to approach it which is somewhat limited in that it will be very time consuming with a large data set, but will get the job done. See attached for my attempt.

You would use a logic statement here. IF [C1] = [C2] THEN 0 ELSE [C1] ENDIF

Does this work for you? Maybe you can mockup a workflow to illustrate the issue

Yes, this can be done with a formula tool. Depending on whether you want to overwrite your 'C1' column, it can look two ways. See attached for more details.

Thanks for the reply. But my issue is to compare every row of C1 with Every row of C2.From the table am comparing the all the values of C1 with all the values of C2.Then if C1 value exists in C2 then that same value which is equal should be 0 in C1.
