oracle存储过程

每个记录都是一次成长。

--=====================================================================================
--◇◆存储过程---示例：


--◇◆select存储过程-
create or replace procedure proc_select(test_cursor out sys_refcursor)
as
begin
 open test_cursor for select * from [用户].[表名];
 dbms_output.put_line('select success!!!');
end proc_select;



----------------------------------------------------------------------------------
--调用
declare
 str sys_refcursor;
 rowinfo [用户].[表名]%rowtype;
begin
 proc_select(str);
 loop
fetch str into rowinfo;
exit when str%notfound;
dbms_output.put_line(rowinfo.[字段]);
 end loop;
end;


◇◆◇◆◇◆◇◆---------------------------------包--------示例--------------------------------------◇◆◇◆◇◆◇◆
--创建包
create or replace package cglin_package
as
  procedure show99;--声明包里的过程
  --其他过程
end cglin_package;




--实现包
create or replace package body cglin_package
as
  procedure show99--创建过程
is
begin
 for i in 1..9 loop
for j in 1..i loop
 dbms_output.put(i*j||'  ');
end loop;
dbms_output.new_line();
 end loop;
end;

--下一个过程
end cglin_package;




--调用
begin
 cglin_package.show99;
end;
