> Currently `ALTER TABLE ... DROP COLUMN(s) ...` syntax will always throw error if the column doesn't exist. We would like to provide an (IF EXISTS) syntax to provide better user experience for downstream handlers (such as Delta) that support it, and make consistent with some other DMLs such as `DROP TABLE (IF EXISTS)`
