Maksim Zhuravkov commented on IGNITE-22032:
-------------------------------------------
Adding a cast to VARCHAR can be used as workaround:
{code}
select json_object('date': '2010-01-01'::DATE::VARCHAR)
{"date":"2010-01-01"}
{code}
> Sql. JSON_OBJECT. Internal representation DATE values leaks into resulting
> JSON object

> Key: IGNITE-22032
> URL: https://issues.apache.org/jira/browse/IGNITE-22032
> Project: Ignite
> Issue Type: Bug
> Components: sql
> Reporter: Maksim Zhuravkov
> Priority: Minor
> Labels: ignite-3
>
> Most databases (see calcite issue) return a json that contains a date string,
> but calcite returns its internal representation of date values (number of
> days as int)
> {code}
> SELECT JSON_OBJECT('a': CAST('2010-01-01' AS DATE)) as c1
> {"a":14610}
> {code}
> Expected behaviour:
> {code}
> SELECT JSON_OBJECT('a': CAST('2010-01-01' AS DATE)) as c1
> {"a":"2010-01-01"}
> {code}
