fix: cannot create a materialized view with struct column

[cykbls01]

What's changed and what's your intention?

PLEASE DO NOT LEAVE THIS EMPTY !!!

Since field desc column not use as column, so we don't need field column desc have column id, remove the generate column id function to fix the problem.
