danny0405 edited a comment on issue #8548: [FLINK-6962] [table] Add create(drop) table SQL DDL URL: https://github.com/apache/flink/pull/8548#issuecomment-498509086 @twalthr 1. I agree that remove the colon between ROW type field name and type is more in line with the sql standard 2. I agree that use left/right paren is more SQL compliant 3. I agree to add comments for row type item 4. The parameterized VARCHARs is supported as a builtin type in Calcite, and our test already extends it. 5. I don't think we should support type keyword like `STRING` or `BYTES`, same reason for SQL compliant 6. REAL is supported by CALCTE, it's hard to say we do not support it, exclude the REAL type will bring a lot of extra work For other data types that are listed in FLIP-37 but not in this PR, i would rather fire a new JIRA issue for tracing them, after all, support the types Flink implement in query execution has higher priority than those that are not totally supported.
