      The identifiers "string" and "bytes" are reserved keywords now and will be used for data types in the future. In case of SQL statements with a function, field, or table name, those identifiers need to be enclosed in backticks: `STRING` or `BYTES`.

      Description

      At a first glance it does not seem that the newly introduced DDL is compliant with FLIP-37. We should ensure consistent behavior esp. also for corner cases.

      Update:
      This brings the SQL DDL closer to FLIP-37. However, there are a couple of known limitations.

      Currently unsupported features:

      • INTERVAL
      • ROW with comments
      • ANY
      • NULL
      • NOT NULL/NULL for top-level types
      • ignoring collation/charset
      • VARCHAR without length (=VARCHAR(1))
      • TIMESTAMP WITH TIME ZONE
      • user-defined types
      • data types in non-DDL parts (e.g. CAST(f AS STRING))
