> Hi all:
>   We  know that kylin's build job often runs late at night, so calling kylin's restful API directly is a very common thing. In this scenario, if  the startTime is equal to the endTime,  something unexpected will happen. The  job calculates all partition data, so the query result is wrong.
>   For example, when I send the following request to kylin.
> curl -X PUT -H "Authorization: Basic XXXXXXX" -H 'Content-Type: application/json' -d '\{"startTime":'1541894400000', "endTime":'1541894400000', "buildType":"BUILD"}' [http://xxxxxx:xxxx/kylin/api/cubes/cube_name/build|http://xxxxxxxxxx/]
> then, the job will calculate all partition data. I find the backend interface of build lacks checksum data range, and the sql of generating the flat table is wrong. 
>   I try to fix this bug, and the patch  is in the attachment.
