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

             Summary: Int and Long can convert to each other in ResultSet
                 Key: IOTDB-922
                 URL: https://issues.apache.org/jira/browse/IOTDB-922
             Project: Apache IoTDB
          Issue Type: Improvement
            Reporter: yuqi


Currently, if the type of a is int64

{code:java}
ResultSet rs = statement.execute("select a from xxx");
{code}

int result = rs.getInt(1) will always return 0, this is not according with most 
JDBC definition, this is, int and long can convert freely as long as this is no 
data overflow.
