> 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}
