绑定oracle UDT的参数名称无效

Question

我正在尝试使用ODP.NET在我的代码中使用UDT。我见过几个例子，但是当我运行我的代码时，我得到一个错误，说无效的参数名称绑定。无法找出代码失败的位置。请在下面找到代码。

Oracle部分：

    create or replace 
TYPE T_SALES_PATTERN is object (siteID   varchar2(10),
 tankID   varchar2(10),
 dayNo     integer, 
 periodID  integer,
 startTime varchar2(4),
 endTime   varchar2(4),
 intraDayPctRate number(3,2),
 totalDailySalesPctRate number(3,2),
 averageDailySales integer,
 ouID varchar2(3)); 

create or replace 
TYPE T_SALES_PATTERN_TABLE is table of T_SALES_PATTERN;

function insertVMIFESalesPatterns( p_vmifeSalesPatterns T_SALES_PATTERN_TABLE) return integer is
begin
for recs in (select * from TABLE(p_vmifeSalesPatterns))
loop
  dbms_output.put_line(recs.siteID);
end loop;

  commit;
return g_SUCCESS;

exception when others then
  return g_ERROR;
end;
