Hi geniuses,
I have a table which contains groups inside Receivers and Payers (2 columns).
Some groups can be Receivers and Payers, for instance , A and B.
B, D and E are only payers.
For the receivers we got A, B and C.
For the payers we have A, B, D and E.
Receivers \\ Payers
A \\ A
B \\ A
A \\ B
A \\ D
B \\ D
C \\ A
B \\ E
A \\ E
How do I create a column 'Group' that contains both Receivers and Payers, not repeated?
What i need:
Group
A
B
C
D
E
Thanks, Regards

SELECT Receivers FROM myTable

UNION

SELECT Payers FROM myTable

I think this is what you're looking for...

Providing easily consumable sample data makes it easier for people to help and more likely...

--Setup Sample Data

declare @transactions as table (Receivers char(1), Payers char(1))

insert into @transactions(Receivers, Payers)

values('A' , 'A')

,('B' , 'A')

,('A' , 'B')

,('A' , 'D')

,('B' , 'D')

,('C' , 'A')

,('B' , 'E')

,('A' , 'E')

--Actual work statement

select distinct [Group]

from (

select Receivers [Group]

from @transactions

union all

select Payers [Group]

from @transactions

) c

It is possible to add a Group By inside each Select?

If yes how do you do it?

Thanks.

I suspect your definition of 'group by' might be different than mine. Using the sample data in your first post how would the resultset look if it did a "Group By inside each Select"?

Hers's another way.

declare @transactions as table (Receivers char(1), Payers char(1))

insert into @transactions(Receivers, Payers)

values('A' , 'A')

,('B' , 'A')

,('A' , 'B')

,('A' , 'D')

,('B' , 'D')

,('C' , 'A')

,('B' , 'E')

,('A' , 'E')

SELECT RecPyr

FROM @transactions

CROSS APPLY (VALUES (Receivers),(Payers)) a(RecPyr)

GROUP BY RecPyr

Now what did you want to do with a GROUP BY inside of the SELECT?

My thought question: Have you ever been told that your query runs too fast?

My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
