Hi Xu,
sorry for late response. I read the code in org.apache.calcite.test.ServerTest,
along with help from Julian, now the problem has been solved.
According to Julian, I replaced the value of parserFactory
"org.apache.calcite.sql.parser.ddl.SqlDdlParserImpl#FACTORY" with
"org.apache.calcite.s
Hi Julian,
It works! Thank you very much!

Looks like you need to be using ServerDdlExecutor rather than
DdlExecutor.USELESS.
Therefore try using org.apache.calcite.server.ServerDdlExecutor#PARSER_FACTO

Hi Oualid,
It's not completely clear what your request is but keep in mind that
Sqlline [1] (which you probably used in the tutorial) is an SQL client like
Dbeaver/Squirrel etc.
The tutorial also provides some examples with the jdbcurl, username,
password. Keep in mind that whatever SQL client you
Xiabo,
Your code seems to work for me, I ran the test case and it passes, see the

No dice still unfortunately =/
If it's any easier, I put a self-contained single class reproduction on
Github:
https://github.com/GavinRay97/calcite-nested-json-subquery-bug/blob/main/src/test/java/com/example/AppTest.java
Is it worth filing a JIRA ticket over you think?

It’s a parser error. That usually means that the user has made a mistake.
Try your SQL on another DB with JSON support before you declare this a Calcite
bug.

That's a valid point, let me see check what some common dialects will
accept for this sort of thing

I think this actually is a bug in Calcite's parser or it's interpretation
I tested on H2, Oracle, and MySQL, the below is valid on those DB's but
fails on Calcite's parser:
=
H2/Oracle
=
SELECT
"houses"."id" AS "id",
"houses"."address" AS "address",
(
Sorry, I realized this might be a time investment to try to debug/reproduce
So I found a website that let me create the schema, rows, and query on
various DB's
Here is an example on Oracle and MySQL that you can view/modify in your
browser:
ORACLE:

Okay, I think maybe I have an idea what is going on
The parser grammar for "JsonNameAndValue":

Has:
e = Expression(ExprContext.ACCEPT_NON_QUERY)
This enum value a
Oh wow, that fixed it!
I changed that line in the parser to be Expression(ExprContext.ACCEPT_ALL)
And now my nested JSON queries work!
The minimal reproduction is:
SELECT JSON_OBJECT(
KEY 'id'
VALUE (SELECT 1)
)
+--+
| EXPR$0 |
+--+
| {"id":1} |
+--+
1 row sele
Well actually, there is one exception -- there's a small bug with the
output being improperly escaped but that bug is already on JIRA and seems
much easier to approach.

When trying to map Java Float Objects to SQL Float, we faild with the following

SQL’s FLOAT type (aka DOUBLE) corresponds to Java’s double.
SQL’s REAL type corresponds to Java’s float.
JDBC method names (e.g. getFloat, getDouble) refer to the Java types.
