------------------------------
Assignee: Saketh Kurnool
> Add support for DATE and TIME conversion to JSON
> ------------------------------------------------
>
> Key: FLINK-40963
> URL: https://issues.apache.org/jira/browse/FLINK-40963
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / Planner
> Reporter: Saketh Kurnool
> Assignee: Saketh Kurnool
> Priority: Major
>
> h1. Issue
> The Flink planner rejects DATE and TIME when used in a JSON conversion
> context (e.g. JSON_OBJECT, JSON_ARRAY, or similar). The type is not
> recognized as scalar or JSON-convertible, causing the statement to fail at
> submission. Concretely:
>
> {code:java}
> Failed to (re)submit Job to Flink: {"errors":["Type 'DATE NOT NULL' is not
> scalar or cannot be converted into JSON."]} {code}
>
> This affects both batch and streaming modes.
> h1. Proposal
> Add the missing type mappings for TIME_WITHOUT_TIME_ZONE and DATE to generate
> the JSON conversion code for them.
> h2. Files to modify
> * JsonGenerateUtils.scala: add cases for DATE and TIME to generate JSON
> conversion code
> * SpecificInputTypeStrategies.java: validate that DATETIME type family can
> be used in JSON context
> * JsonFunctionsITCase.java: add IT coverage for the two missing types
