---------------------------------------
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
