-------------------------------------
Hi [~albericbyte] , I check this in the Calcite. It can all works well:
{code:java}
select JSON_OBJECT('name': dname, 'type': deptno) from dept;
select JSON_OBJECT('name': 'foo', 'type': 'VARCHAR');{code}
Can you try to reproduce this bug in the Calcite and Please add unit test for
this. We can make this issue more clearly.
> For druid sql JSON_OBJECT() function results in RUNTIME_FAILURE when querying

> 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}
