Oracle存储过程代码实例一则

1、用来插入大量测试数据的存储过程CREATE OR REPLACE PROCEDURE INSERTAMOUNTTEST(ST_NUM IN NUMBER,ED_NUM

1、用来插入大量测试数据的存储过程
CREATE OR REPLACE PROCEDURE INSERTAMOUNTTEST
(
ST_NUM IN NUMBER,
ED_NUM IN NUMBER
)
IS
BEGIN
declare
i number;
begin
FOR i IN ST_NUM..ED_NUM LOOP
INSERT INTO tb values(i,i,'3','3','3',100,'0');
END LOOP;
end;
END;

运行：
sql>execute INSERTAMOUNTTEST(1,45000) -- 一次插入45000条测试数据

2、从存储过程中返回值
create or replace procedure spaddflowdate
(
varAppTypeId in varchar2,
varFlowId in varchar2,
DateLength in number,
ReturnValue out number --返回值
)
is
begin
insert into td values(varAppTypeId,varFlowId,DateLength)
returning 1 into ReturnValue; --返回值
commit;
exception
when others then
rollback;
end;

存储过程的执行
sql>variable testvalue number;
sql>execute spaddflowdate('v','v',2,:testvalue);
sql>print
就可以看到执行结果

3、用包实现存储过程返回游标：
create or replace package test_p
as

type outList is ref cursor;

PROCEDURE getinfor(taxpayerList out outList);

end test_p;
/

create or replace package body test_p as PROCEDURE getinfor(taxpayerList out outList) is begin
OPEN taxpayerList FOR select * from
td where tag='0';

end getinfor;

end test_p;
/



运行：

set serverout on; --将输出工具打开

variable x refcursor;

execute test_p.getinfor(:x);

exec test_p.getinfor(:x);

print x;

drop package test_p;
