- How would perform the Alteryx equivalent of a GROUP BY and HAVING Clause

- How many ways are possible to go about it?

@FogoFortitude,

 

Here's how:

 

  • SUMMARIZE
    • Groupby A
    • Count A
  • FILTER the output of the summarize with
    • Count > 1
  • Join the original data (going into the summarize) with the output of the Filter on A = A
    • Unselect the RIght_A field and the Count field

 

Cheers,

Mark,

Thanks for the solution but I'm not sure why you are joining the output of the summarize/filter flow to the original data?

Doesn't the original SQL return counts by group A?

If Table contains:

A
---
XX
XX
YY
YY
YY
YY
ZZ

SELECT A, Count(*)
FROM TABLE
GROUP BY A
HAVING COUNT(*) > 1

Returns:

A  | COUNT(*)
-------------
XX | 2
YY | 4

Isn't that what the result of the summarize & filter control would produce?

Maybe I'm looking at it wrong (it won't be the first time).

Thanks,

Lee

@lrygiel,

 

Yes.  You've got a point. Summarize & Filter is all that's needed.
