Maksim Zhuravkov updated CALCITE-6362:
--------------------------------------
Component/s: core
> JSON_OBJECT. Internal representation DATE values leaks into resulting JSON
> object
> ---------------------------------------------------------------------------------
>
> Key: CALCITE-6362
> URL: https://issues.apache.org/jira/browse/CALCITE-6362
> Project: Calcite
> Issue Type: Bug
> Components: core
> Reporter: Maksim Zhuravkov
> Priority: Minor
>
> When a CAST function is used inside a JSON_OBJECT, then resulting JSON
> contains a number of days instead
> {code}
> SELECT JSON_OBJECT('a': CAST('2010-01-01' AS DATE)) as c1;
> {"a":14610}
> {code}
> I expected to get a date in a string form as many databases do in such case:
> Bigquery:
> {code}
> SELECT JSON_OBJECT('a', CAST('2010-01-10' AS DATE))
> {"a":"2010-01-10"}
> {code}
> PostgreSQL
> {code}
> SELECT json_build_object('a', '2010-01-01'::DATE)
> {"a":"2010-01-01"}
> {code}
> MySql
> {code}
> SELECT json_object('a', DATE '2010-01-01')
> {"a": "2010-01-01"}
> {code}
