如何在java中处理oracle中的对象数组？
在java中处理oracle中的对象数组（嵌套表）：
sp文件：
-------------------------------CreateObjectType----------------------------------
createorreplacetypeo_tmpasobject(
useridvarchar2(10),
usernamevarchar2(20)
);
/
---------------------------CreateNestedTableTypeOnBaseObjectType------------------------
createorreplacetypetmp_arrayistableofo_tmp；

----------------------------CreateaPackageFile-----------------------------------------------------------

proceduregetObject(obj_arrouttmp_array)
is

tmp_obj:=o_tmp('test1'||n,'fuyue'||n);
