hongbin ma commented on KYLIN-1989:
-----------------------------------
I can reproduce you issue now. kylin does not support case when in
aggregators(sum,min,max) yet. Only "case when" for dimension is supported, for
example:
SELECT (CASE WHEN ("TEST_KYLIN_FACT"."LSTG_FORMAT_NAME" = 'Auction') THEN
'Auction2' ELSE "TEST_KYLIN_FACT"."LSTG_FORMAT_NAME" END) AS
"LSTG_FORMAT_NAME__group_",
SUM("TEST_KYLIN_FACT"."PRICE") AS "sum_PRICE_ok"
FROM "TEST_KYLIN_FACT" "TEST_KYLIN_FACT"
GROUP BY (CASE WHEN ("TEST_KYLIN_FACT"."LSTG_FORMAT_NAME" = 'Auction') THEN
'Auction2' ELSE "TEST_KYLIN_FACT"."LSTG_FORMAT_NAME" END)
as a workaround now you can modify the "case when" to a filter
> Sum issue: result not consistent with hive

> fact_product.quantity else 0 end)
> FROM fact_product_sales as fact_product
> join dim_product as product on fact_product.product_id = product.id
