oracle procedure for update,oracle 存储过程循环执行update语句

其实二楼写的最简单，但对于新手，最好别那么写，至于1楼，如果数据不是很多，没必要搞个游标。你也可以看看我写的

create or replace procedure P_Update(o_vc_message out varchar2)

is

type column1 is table of table1.column1%type index by binary_integer;

col1s column1;

type rid is table of rowid index by binary_integer;

rids rid;

temp table1.column1%type;

begin

select column1,rowid bulk collect into col1s,rids from table1;

if (column1.count != 0) then

for i in col1s.first..col1s.last loop

temp := col1s(i);--处理 col1s(i) 想干嘛干嘛

update table1 set column1 = temp where rowid = rids(i);

end loop;

end if;

o_vc_message := 'OK!';

exception

when others then

o_vc_message := 'exception happend.' || sqlcode || sqlerrm;

rollback;

return;

end P_Update;

如果仅仅是简单处理column1，比如加1什么的，就别搞那么复杂，一个sql就ok了。
