> Partition time column may never be added

> Key: KYLIN-3665
> URL: https://issues.apache.org/jira/browse/KYLIN-3665
> Project: Kylin
> Issue Type: Bug
> Reporter: Chao Long
> Assignee: Chao Long
> Priority: Major
> Fix For: v2.6.0
>
>
> 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.
