Date Wed, 08 Nov 2017 22:36:00 GMT
Rong Rong created FLINK-8038:
--------------------------------

             Summary: Support MAP literal
                 Key: FLINK-8038
                 URL: https://issues.apache.org/jira/browse/FLINK-8038
             Project: Flink
          Issue Type: New Feature
          Components: Table API & SQL
            Reporter: Rong Rong
            Assignee: Rong Rong


Similar to https://issues.apache.org/jira/browse/FLINK-4554
We want to support Map literals which is supported by Calcite:
https://calcite.apache.org/docs/reference.html#value-constructors


{code:sql}
SELECT
  MAP['key1', f0, 'key2', f1] AS stringKeyedMap,
  MAP['key', 'value'] AS literalMap,
  MAP[f0, f1] AS fieldMap
FROM
  table
{code}

This should enable users to construct MapTypeInfo, one of the CompositeType.
