-----------------------------------
Summary: Nested JSON_OBJECT creation does not produce proper json
Key: CALCITE-4989
URL: https://issues.apache.org/jira/browse/CALCITE-4989
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.29.0
Reporter: Mans Singh
I am trying to create a nested json object using JSON_OBJECT and am getting a
json with escaped quotes.
I have the following query in sql line :
`select JSON_OBJECT(
KEY 'level1'
VALUE(
JSON_OBJECT(
KEY 'level2'
VALUE(
JSON_OBJECT(
KEY 'level3'
VALUE 'val3')
)
)
)
)
from (values ('\{"a":{"b":2}}')) t(v);`
And it produces the result:
+-------------------------------------------------------------+
| EXPR$0 |
+-------------------------------------------------------------+
| \{"level1":"{\"level2\":\"{\\\"level3\\\":\\\"val3\\\"}\"}"} |
+-------------------------------------------------------------+
