### What changes were proposed in this pull request? As described in #32831, Spark has compatible issues when querying a view created by an older version. The root cause is that Spark changed the auto-generated alias name. To avoid this in the future, we could ask the user to specify explicit column names when creating a view. ### Why are the changes needed? Avoid compatible issue when querying a view ### Does this PR introduce _any_ user-facing change? Yes. User will get error when running query below after this change ``` CREATE OR REPLACE VIEW v AS SELECT CAST(t.a AS INT), to_date(t.b, 'yyyyMMdd') FROM t ``` ### How was this patch tested? not yet Closes #32832 from linhongliu-db/SPARK-35686-no-auto-alias.
