回复网友问题,关于一个数值和字符串一起累加的问题！[@more@]

急急急！！！请各位大哥赐教一个数值和字符串一起累加的问题！

关键字：字符串相加

一。创建测试表
CREATE TABLE addtest(
CODE VARCHAR2(20),
MONEY NUMBER,
FLAG VARCHAR2(20)
);
INSERT INTO addtest VALUES (1001, 99.00, '新建');
INSERT INTO addtest VALUES (1002, 100.00, '编辑');
INSERT INTO addtest VALUES (1002, 300.00, '新建');
INSERT INTO addtest VALUES (1002, 500.00, '取消');
INSERT INTO addtest VALUES (1002, 700.00, '编辑');
INSERT INTO addtest VALUES (1003, 20, '取消');
INSERT INTO addtest VALUES (1003, 60, '新建');
COMMIT;
select * from addtest;

二。想要得到的结果：
CODE MONEY FLAG
1001 99 新建
1002 1600 新建,编辑(2),取消
1003 80 新建,取消

拜托各位前辈大哥不吝赐教，先谢过了，小弟急啊！
