java调用oracle函数返回自定义类型

[leizi472425328]

包定义如下：
-------------------------------------------------------
---------------------定义包头--------------------------
-------------------------------------------------------
create or replace package pck_test is
type cursorref is ref cursor; -----定义游标
type temp_record is record -----定义游标输出记录类型
(
itemId mini_t_item_dict.item_id%TYPE,
describe mini_t_item_dict.describe%TYPE
);
type statistic_record is record -----定义输出记录类型，保存一项结果
(
itemId mini_t_item_dict.item_id%TYPE,
describe mini_t_item_dict.describe%TYPE,
recordCount number
);
type statistic_record_array is TABLE OF statistic_record;-----定义记录型数组
function getStatistics (itemid mini_t_item_dict.item_id%TYPE) return statistic_record_array; --------定义函数
end pck_test;
-------------------------------------------------------
---------------------定义包体--------------------------
-------------------------------------------------------
create or replace package body pck_test is
function getStatistics
(itemid mini_t_item_dict.item_id%TYPE)
return statistic_record_array
is
vs_temp_record temp_record;
vs_statistic_record statistic_record;
vs_statistic_record_array statistic_record_array;
vs_cursorref cursorref;
--vs_recordCount number;
begin
open vs_cursorref for
select t.item_id, describe from mini_t_item_dict t where t.parent_id = itemId;
fetch vs_cursorref into vs_temp_record;
while vs_cursorref%found loop
vs_statistic_record_array.extend;
vs_statistic_record.itemId := vs_temp_record.itemId;
vs_statistic_record.describe := vs_temp_record.describe;
select count(*) into vs_statistic_record.recordCount
from mini_t_adverse_form1 f
where f.item_id = vs_statistic_record.itemId;
vs_statistic_record_array(vs_statistic_record_array.count) := vs_statistic_record;
fetch vs_cursorref into vs_temp_record;
end loop;
return vs_statistic_record_array;
close vs_cursorref;
end;
end pck_test;

在java中调用：
public List<Statistics> statisticsCount(int pid){
try {
CallableStatement cstm = this.getConnection().prepareCall("{?=call pck_test.getstatistics(?)}");
cstm.setInt(2, pid);
cstm.registerOutParameter(1,OracleTypes.ARRAY,"pck_test.statistic_record_array");//这出错了，异常在下面
cstm.execute();
List<Statistics> stalit = new ArrayList<Statistics>();
stalit = (List<Statistics>) cstm.getObject(1);
return stalit;
} catch (CannotGetJdbcConnectionException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}

异常：java.sql.SQLException: 无效的名称模式: pck_test.statistic_record_array

求大侠指教，谢谢！！！

换成大写试试？我也遇到了过这问题，大写就没报错这个错。但是又出现其它的错pck_test.statistic_record_array换成大写

[飞身剑客]

statistic_record_array 要全部改成大写，oracle在创建时已经全部转成大写了。
