jackierwzhang opened a new pull request, #36345: URL: https://github.com/apache/spark/pull/36345
### What changes were proposed in this pull request? As a syntax guard for downstream datasource that could handle empty schema, we enforce user to use `()` during table creation queries. E.g. `CREATE TABLE table () USING parquet`. Note that the `[CREATE OR] REPLACE` is excluded from this change due to additional complexity. ### Why are the changes needed? To explicitly make sure user are aware that they are creating a table with no columns. ### Does this PR introduce _any_ user-facing change? Existing code that calls `CREATE TABLE table USING ...` will fail. ### How was this patch tested? New unit test. -- This is an automated message from the Apache Git Service.
