------------------------------------

             Summary: For druid sql JSON_OBJECT() function results in 
RUNTIME_FAILURE when querying INFORMATION_SCHEMA.COLUMNS
                 Key: CALCITE-6437
                 URL: https://issues.apache.org/jira/browse/CALCITE-6437
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.35.0
            Reporter: AlbericByte


there is but for druid sql :

[https://github.com/apache/druid/issues/16356]
h3. Description

Running the following query
{code:java}
select JSON_OBJECT('name': COLUMN_NAME, 'type': DATA_TYPE) from 
INFORMATION_SCHEMA.COLUMNS{code}
{{ }}
 
produces
{{}}
{code:java}
Error: RUNTIME_FAILURE (OPERATOR) cannot translate call json_object($t17, $t18, 
$t3, $t19, $t7) java.lang.RuntimeException   {code}
 
Note that the error message quotes the json_object call to receive five 
parameters, but maybe that's an unrelated internal detail.

For comparison, the following works (but is useless):
{code:java}
select JSON_OBJECT('name': 'foo', 'type': 'VARCHAR'){code}
