> The partition time column will never be added to the WHERE clause if the partition date
column is type of int or bigint and the date format is "yyyyMMdd", "yyyyMMddHH", "yyyyMMddHHmm"
or "yyyyMMddHHmmss".
> Let’s say I have a fact table with two date partition column: day as the format of
integer (yyyyMMdd) and minute as the format of string (HHmm). I have models created based
on it and set the Partition Date Column to be “day” with the format of yyyyMMdd and the
Partition Time Column to be “minute” with the format of HHmm. When I build the cube built
on top of that model, I set the Start Date to be 2018-11-01 00:00:00 and the End Date to be
2018-11-01 01:00:00. The building process is supposed to retrieve the data from the fact table
in the range of “day = 20181101 and minute>=’0000’ and minute<’0100’”. However,
it retrieves the data in the range of “WHERE 1=1 AND (DAY >= 20181101 AND DAY < 20181101),
so no data are actually retrieved.
