下面是项目二的代码 本代码我是留着备份学习的 以供参考：
存储过程：
存储过程：
插入数据：
CREATE OR REPLACE Procedure p_insert_t_cls --存储过程名称
(
p_stuid in CLASSES.ID%type,
p_stuname in varchar
)
as
BEGIN
insert into classes
values
(p_stuid,p_stuname);
commit;
end;
===============================================
删除 ：（带返回参数）
create or replace procedure proc_delete
(
isid in number , P_ROWS OUT NUMBER
)
is
begin
delete classes where id=isid;
If SQL%Found Then
DBMS_OUTPUT.PUT_LINE('删除成功！');
P_ROWS := 1;
Else
DBMS_OUTPUT.PUT_LINE('删除失败！');
P_ROWS := 0;
End If;
commit;
end
;
删除 ： （不带返回参数）
create or replace procedure p_delete_t_cls1(
cla_id in Number
)
is
begin
DELETE FROM classes WHERE id = cla_id;
commit;
end p_delete_t_cls1;
删除 ： （不带返回参数）指定ID删除
create or replace procedure p_delete_t_cls is
begin
DELETE FROM classes WHERE id = 7;
commit;
end p_delete_t_cls;
====================================================
修改数据：（不带返回参数）
create or replace procedure p_update_t_cls1(
p_stuid in Number,
p_stuname in Nvarchar2
)
is
begin
update classes x set x.classname = p_stuname where x.id = p_stuid;
commit;
end p_update_t_cls1;
修改数据： ：（带返回参数）
create or replace procedure proc_update(
p_stuid in Number,
p_stuname in Nvarchar2,
P_ROW out number
)
is
begin
update classes set classname = p_stuname where id = p_stuid;
If SQL%Found Then
DBMS_OUTPUT.PUT_LINE('更新成功！');
P_ROW := 1;
Else
DBMS_OUTPUT.PUT_LINE('更新失败！');
P_ROW := 0;
End If;
commit;
end proc_update;
修改数据： ： （不带返回参数）指定ID修改
create or replace procedure p_update_t_cls
is
begin
update classes x set x.classname = '44' where x.id = 3;
commit;
end p_update_t_cls;
====================================================
查询所有数据：（带返回参数 游标）
CREATE OR REPLACE PACKAGE pkg_test1
AS
TYPE myrctype IS REF CURSOR;
PROCEDURE get (p_id NUMBER, p_rc OUT myrctype);
END pkg_test1 ;
create or replace function testpro1 return types1.cursorType1 is
lc1 types1.cursorType1;
begin
open lc1 for select id,classname from classes;
return lc1;
end testpro1;
传递ID查询数据：（带返回参数 游标）传递ID查询数据
create or replace package types as
type cursorType is ref cursor;
end;
create or replace function testpro(IV IN NUMBER) return types.cursorType is
lc types.cursorType;
begin
open lc for select * from test where ID=IV;
return lc;
end testpro;
