ZheHu created CALCITE-5257:
------------------------------

             Summary: NVARCHAR is treated as "UNKNOWN TYPE" when searching Oracle
                 Key: CALCITE-5257
                 URL: https://issues.apache.org/jira/browse/CALCITE-5257
             Project: Calcite
          Issue Type: Bug
          Components: avatica
    Affects Versions: avatica-1.22.0
            Reporter: ZheHu
            Assignee: ZheHu


When I run the following SQL to query Oracle through Calcite:
{code:java}
select NVARCHAR_COL from oracleSchema.t1
{code}
A RuntimeException is thrown by Avatica(in Method AbstractCursor.createAccessor()):
{code:java}
unknown type -9(which represents NVARCHAR)
{code}
