Hi, thank you for talking to you about this problem and I've taken care of it,
and it's not that you understand that, but maybe it's not the fact that it has
a relationship with the fact that it's in kylin, and that's actually the view
is that you're building a dimension table to correlate the fact sheet, and the
dimension table is all the fields that are derived from the fact sheet so that
you can construct the cube.

hi, thank you for discussing this problem with you. I have solved it. Not that
you understand it, maybe you don't know the relationship between kylin's
dimension table and fact table.
