             Summary: [Java][FlightRPC] FlightSQL error: 'Parameter ordinal out of range' executing a prepared stmt with params
                 Key: ARROW-18300
                 URL: https://issues.apache.org/jira/browse/ARROW-18300
             Project: Apache Arrow
          Issue Type: Bug
          Components: FlightRPC, Java
    Affects Versions: 10.0.0
            Reporter: James Henderson


Hey again :) 

I'm getting a 'parameter ordinal 1 out of range' error trying to set a parameter on the returned AvaticaPreparedStatement. Repro:

* Open a FlightSQL JDBC connection
* {{conn.prepareStatement}} with a SQL query containing params (e.g. {{INSERT INTO users (id, name) VALUES (?, ?)}})
* `ps.setString(1, "foo")` -> above error, thrown from {{AvaticaPreparedStatement.getParameter(int)}}

I had a bit of a dig to try to identify a potential cause:
* the {{Meta.Signature}} passed to the {{AvaticaPreparedStatement}} on creation has an empty parameter list - this is what causes the out-of-bounds error.
*  in {{ArrowFlightMetaImpl.prepare}}, it calls {{newSignature}}, but this only takes the SQL query, and so {{newSignature}} creates the signature with the empty list. The call to {{ArrowFlightSqlClientHandler.prepare}} happens on the line after - could we pass the param Schema from this result to {{newSignature}}?

Let me know if I can help narrow this down further or help with the fix :)

James
