Hi Kylin team,
I found an issue while server side PreparedStatement enabled. The second time
query and after's result will be different from the first when query TopN, and
the result is not right.
Part of Cube info:
Dimensions
TRANS_ID
PART_DT
SELLER_ID
BUYER_ID
Measures:
SUM(PRICE)
MAX(PRICE)
TOPN(PRICE) Group By:KYLIN_SALES.SELLER_ID,KYLIN_SALES.BUYER_ID
The First query result:
