could we add tests covering this behavior? e.g a test that fails when only a query, columns, like etc is provided in a create statement

Improved the tests, note Snowflake supports specifying the options either before or after the "source" definition while the SQL output assumes one. Added tests for both options.

CREATE TEMP TABLE dst AS (SELECT * FROM src) ON COMMIT PRESERVE ROWS
