请教：oracle occi 读写clob类型数据

[fibbery]

各位好：

最近需要通过occi方式，调用oracle的一个存储过程，

存储过程如下：

CREATE OR REPLACE PROCEDURE TESTCLOB 
(
  PARAM1 IN NUMBER  
, PARAM2 IN CLOB  
) AS 
BEGIN
  insert into test(COLUMN1,COLUMN2) values(PARAM1,PARAM2);
  NULL;
END TESTCLOB;

访问的表如下：
CREATE TABLE "TEST"
  (
    "COLUMN1" NUMBER,
    "COLUMN2" CLOB
  )

C++访问部分如下：
unsigned char str[]="1234567890";
_stmt = _conn->createStatement("begin TESTCLOB(:1,:2); end;");

Clob clobXmlInfo;
clobXmlInfo.setEmpty(_conn);
if(!clobXmlInfo.isInitialized())
{
   return false;
}
clobXmlInfo.write(10,str,10);
_stmt->setClob(2,clobXmlInfo);
_stmt->setUInt(1,xmlNo);

if (_stmt != NULL)
{
  _stmt->executeUpdate();
  _conn->commit();
  _conn->terminateStatement(_stmt);
  _stmt = NULL;
}

运行后，抛出异常：
ORA-22275: invalid LOB locator specified

此处不知道该怎么解决，请高手指点！
