-----------------------------------------
Summary: Support for RETURNING clause of JSON_QUERY
Key: CALCITE-6365
URL: https://issues.apache.org/jira/browse/CALCITE-6365
Project: Calcite
Issue Type: New Feature
Reporter: Dawid Wysakowicz
SQL standard says {{JSON_QUERY}} should support {{RETURNING}} clause similar to
{{JSON_VALUE}}. Calcite supports the clause for JSON_VALUE already, but not for
the JSON_QUERY.
{code}
<JSON query> ::=
JSON_QUERY <left paren>
<JSON API common syntax>
[ <JSON output clause> ]
[ <JSON query wrapper behavior> WRAPPER ]
[ <JSON query quotes behavior> QUOTES [ ON SCALAR STRING ] ]
[ <JSON query empty behavior> ON EMPTY ]
[ <JSON query error behavior> ON ERROR ]
<right paren>
<JSON output clause> ::=
RETURNING <data type>
[ FORMAT <JSON representation> ]
{code}
