Is this configuration kylin.query.enable-dynamic-column  work for you?

I set it in project level, but it didn’t’ work for me. 


Is there anyone else tried this?

I don't think the configuration can be override in cube level, you need to
set it in the file or in the project's config, and you
don't need to rebuild the cube.

Hi Shaofeng,

   I didn't find this configuration parameter in the configuration list via, could you help to
check that?


Besides, could this configuration be overwritten in the Cube Level? I tried
this configuration in the Cube level, but it did not works on the result of
count(column). Moreover, I re-builded this cube also, but it did not work

One suggestion, such new feature should be enabled by default; Otherwise,
most people won't know it, even we add it to the configuration list...

You may set the configuration 'kylin.query.enable-dynamic-column' to true in, and test it.

Hi Ma Gang, 


   Thank you for your reply.   The column ‘fzy_bill_code’ is from fact

   But what do you mean about ‘enable dynamic column configuration.”

Is the column 'fzy_bill_code' from fact table? If so, the issue should have
been fixed in, you need to
enable dynamic column configuration.

Hi all,  


   Run the same sql on kylin and hive, but got different result.    It seems
kylin has count NULL as 1, but hive count it as 0. 


   The sql is as below: 

     select  count(fzy_bill_code) from gjst.sh_fetch_sale_base_fact where
dates between '2018-09-01' and '2018-10-18'


   The result on kylin is :  2889422  ,  but 2688289 on hive.     


      Anyone who knows the solution for this?   Thanks a lot.
