请教存储过程的编写
场景：
1410500000000018011
2410500000000018041
3410500000000018031
4410500000000018051
5410500000000018142
6410500000000018112
7410500000000018111
841050000000001814
9410500000000018845
10410500000000018832
11410500000000018821
12410500000000018910

目标：
14105000000000180 11 41 31 51
54105000000000181 42 12 11 4
9 4105000000000188 45 32 21
12 4105000000000189 10

注：不是拼接，是行转列，数据很多，分组很多，所以需要用存储过程解决，
11 41 31 51 '' ''
42 12 11 4 '' ''
45 32 21 '' '' ''
10 '' '' '' '' ''
这个最多六列，没有数据的为空
请高人帮忙解答，谢谢

ms不需要存储过程，用wm_concat函数就可以实现

create table t(id int, x int, y int);
insert into t values (1, 4105000000000180, 11);
insert into t values (2, 4105000000000180, 41);
insert into t values (3, 4105000000000180, 31);
insert into t values (4, 4105000000000180, 51);
insert into t values (5, 4105000000000181, 42);
insert into t values (6, 4105000000000181, 12);
insert into t values (7, 4105000000000181, 11);
insert into t values (8, 4105000000000181, 4);
insert into t values (9, 4105000000000188, 45);
insert into t values (10, 4105000000000188, 32);
insert into t values (11, 4105000000000188, 21);
insert into t values (12, 4105000000000189, 10);
commit;

select min(id), wm_concat(y) from t group by x;
[解决办法]
select min(id), x, wm_concat(y) from t group by x;

40分归我了。
首先创建一个结果表，当然是用来装结果集。

第一步，先拼接，用WMSYS.WM_CONCAT函数。
第二步，更新，拼接后的字符后面再连接一个逗号
第三步，拆分---看例子：

---根据逗号拆分

CREATE OR REPLACE PROCEDURE Py_Rpt_Consume_Info AS
CURSOR My_Cursor IS
SELECT Id, NAME FROM p_k t;
Row_Set My_Cursor%ROWTYPE;
Str1 VARCHAR2(2000);
Str2 VARCHAR2(2000);
Str3 VARCHAR2(2000);
Str4 VARCHAR2(2000);
--Num1 NUMBER;
BEGIN
EXECUTE IMMEDIATE 'TRUNCATE TABLE p_kk';
FOR Row_Set IN My_Cursor LOOP
Str1 := Row_Set.NAME;
WHILE Instr(Str1, ',', 1) > 0 LOOP
Str2 := Substr(Str1, 1, Instr(Str1, ',', 1));
Str1 := Substr(Str1, Instr(Str1, ',', 1) + 1);
/* Str3 := Substr(Str2,
Instr(Str2, '(', 1) + 1,
Instr(Str2, ')', 1) - Instr(Str2, '(', 1) - 1);
Str4 := Substr(Str2, 1, Instr(Str2, '(', 1) - 1);*/
--NUM1 := TO_NUMBER(STR3);
/*-----
INSERT INTO TTTTT (STR1, STR2, STR3, STR4, NUM1)
SELECT STR1, STR2, STR3, STR4, NUM1 FROM DUAL;
COMMIT;
----- */
INSERT INTO p_Kk
(Id, NAME)
SELECT Row_Set.Id, Str2 FROM Dual;
COMMIT;
END LOOP;

END LOOP;
END Py_Rpt_Consume_Info;
