create table TESTTB
(
ID VARCHAR2(30),
NAME VARCHAR2(30)
)

Insert into testtb values('1','21');
Insert into testtb values('2','22');
Insert into testtb values('3','23');
Insert into testtb values('4','24');

1、用来插入数据，没有返回值
CREATE OR REPLACE PROCEDURE TESTA(PARA1 IN VARCHAR2, PARA2 IN VARCHAR2)
AS
BEGIN
INSERT INTO HUANGBIAO.TESTTB(ID, NAME) VALUES (PARA1, PARA2);
END TESTA;

2、查询只有一个返回值的结果集合
CREATE OR REPLACE PROCEDURE TESTB(PARA1 IN VARCHAR2, PARA2 OUT VARCHAR2)
AS
BEGIN
SELECT NAME INTO PARA2 FROM TESTTB WHERE ID = PARA1;
END TESTB;

3、查询有多个返回值的集合（一组数据）
CREATE OR REPLACE PACKAGE TESTPACKAGE AS
TYPE TEST_CURSOR IS REF CURSOR;
end TESTPACKAGE;

CREATE OR REPLACE PROCEDURE TESTC(P_CURSOR out
TESTPACKAGE.TEST_CURSOR) IS
BEGIN
OPEN P_CURSOR FOR
SELECT * FROM HUANGBIAO.TESTTB;
END TESTC;


存储器和函数的区别？
最本质的区别是存储过程是命令, 而函数是表达式的一部分


create or replace procedure proc_select(
table_id in varchar2
)as
hbsql varchar2(500);
begin
	hbsql:='select name from testtb where id='||table_id;
	execute immediate hbsql;
end;
备注：上面的变量不能使用sql，即“hbsql”不能写为“sql”
execute proc_select('3');


create or replace procedure proc_insert
(
id in varchar2, --输入序号
name in varchar2 --输入姓名
) as
str_sql varchar2(500);
begin
str_sql:='insert into testtb values(:1,:2)';
execute immediate str_sql using id,name; --动态执行插入操作
exception
when others then
null;
end ;

SQL> execute proc_insert('11',’dinya’);
