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.

The code that parses
CREATE TABLEin the Snowflake dialect assumed that if theAS,LIKEorCLONEoptions are used, then no other options can be specified. That is not true, so that restriction is now removed.For example:
CREATE TEMP TABLE dst AS (SELECT * FROM src) ON COMMIT PRESERVE ROWS
