Aggregate Operations with Case Specific data - response (3) by Mandar.Nayak

Thank you Adeel and Deiter.
The query is a regular SUM query - SELECT RGN_CD, SUM(PD_AMT) FROM RGN_PYMNT GROUP BY 1. The column is defined as not casespecific.
 
This isnt really an issue but I am just curious if there is a specific behaviour to aggregating mixed case data.
And it seems as though there isnt, so any of the possible values could be returned by the aggregate operation.
 
Thanks again for your responses.
 
regards,
Mandar
