Mryange opened a new pull request, #34591:
URL: https://github.com/apache/doris/pull/34591
## Proposed changes
Evaluates a (possibly empty) list of key-value pairs and returns a JSON
object containing those pairs. An error occurs if any key name is NULL or the
number of arguments is odd.
```
mysql [test2]>select * from test;
+------+------+
| id | str |
+------+------+
| 1 | NULL |
+------+------+
1 row in set (0.06 sec)
mysql [test2]>select json_object(str,id) from test;
+----------------------------------------------------+
| json_object(str, cast(id as VARCHAR(65533)), '62') |
+----------------------------------------------------+
| {"":1} |
+----------------------------------------------------+
1 row in set (0.12 sec)
```
now
```
mysql [test2]>select json_object(str,id) from test;
ERROR 1105 (HY000): errCode = 2, detailMessage =
(127.0.0.1)[CANCELLED][INTERNAL_ERROR] function json_object can not input null
value , JSON documents may not contain NULL member names.
```
