在Java / Oracle中检索存储过程的参数infors

我在将oracle 9i迁移到11g时遇到了以下问题：由DatabaseMetaData检索的存储过程的参数infors与oracle 11g没有错误

这是我的测试

预言 

create or replace procedure prodc_test(
  -- numeric datatypes --
  pparam01 float,        
  pparam02 number,        
  --pparam03 binary_float, not available in 9i --        
  --pparam04 binary_double, not available in 9i --                
  -- character datatypes --
  pparam20 char, 
  pparam21 in varchar, 
  pparam22 in out varchar2, 
  pparam23 out nchar, 
  pparam24 nvarchar2,
  pparam25 long,
  -- date datatype -- 
  pparam30 date,        
  pparam31 timestamp,
  pparam32 timestamp with time zone,
  pparam34 timestamp with local time zone,
  -- lob datatypes --
  pparam40 blob,
  pparam41 clob,
  pparam42 nclob,
  pparam43 bfile,
  -- raw and long raw datatypes --
  pparam50 raw,
  pparam51 long raw,
  -- rowid and urowid datatypes --
  pparam60 rowid,
  pparam61 urowid
) as 
begin
     --null;
     pparam22 := 'test22';
     pparam23 := 'test23';
end;
/

的java 

DatabaseMetaData dbMetaData = dbConn.getMetaData();
LOGGER.debug("DB DriverVersionn ={}", dbMetaData.getDriverVersion());
LOGGER.debug("DB Product Name   ={}", dbMetaData.getDatabaseProductName());
LOGGER.debug("DB Product Version={}", dbMetaData.getDatabaseProductVersion());
LOGGER.debug("DB Driver Name    ={}", dbMetaData.getDriverName());
LOGGER.debug("DB Driver Version ={}", dbMetaData.getDriverVersion());
LOGGER.debug("DB Username       ={}", dbMetaData.getUserName());
LOGGER.debug("DB URL            ={}", dbMetaData.getURL());

String procedure = "PRODC_TEST";
ResultSet tSchema = dbMetaData.getProcedureColumns(null, null, procedure, null);
while (tSchema.next()) {
    String fieldName = tSchema.getString("COLUMN_NAME").substring(1);
    LOGGER.debug("getProcedureParameters({}), COLUMN_NAME:{}, COLUMN_TYPE:{}, DATA_TYPE:{}, TYPE_NAME:{}", procedure, fieldName,
            tSchema.getInt("COLUMN_TYPE"), tSchema.getString("DATA_TYPE"), tSchema.getString("TYPE_NAME"));
    }
}
tSchema.close();

使用oracle 9i，输出

DB DriverVersionn =11.2.0.3.0

使用oracle 11g，输出为

getProcedureParameters(PRODC_TEST), COLUMN_NAME:PARAM61, COLUMN_TYPE:0, DATA_TYPE:1111, TYPE_NAME:urowid

=＆GT;问题：COLUMN_TYPE = 0（java.sql.DatabaseMetaData.procedureColumnUnknown）和DATA_TYPE = 1111（java.sql.Types.OTHER）

为什么呢？这是一个错误吗？解？ 非常感谢
