一:Java如何实现对存储过程的调用:
①不带输出参数的
---------------不带输出参数的----------------------------------
create procedure getsum
@n int =0<--此处为参数-->
as
declare @sum int<--定义变量-->
declare @i int
set @sum=0
set @i=0
while @i<=@n begin
set @sum=@sum+@i
set @i=@i+1
end
print 'the sum is '+ltrim(rtrim(str(@sum)))


--------------在SQL中执行:--------------------
exec getsum 100


------------在JAVA中调用:---------------------
JAVA可以调用   但是在JAVA程序却不能去显示该存储过程的结果 因为上面的存储
过程的参数类型int 传递方式是in(按值)方式
import java.sql.*;
public class ProcedureTest 
{
public static void main(String args[]) throws Exception
{
//加载驱动
DriverManager.registerDriver(new sun.jdbc.odbc.JdbcOdbcDriver());
//获得连接
Connection conn=DriverManager.getConnection("jdbc:odbc:mydata","sa","");




//创建存储过程的对象
CallableStatement c=conn.prepareCall("{call getsum(?)}");

//给存储过程的参数设置值
c.setInt(1,100);   //将第一个参数的值设置成100

//执行存储过程
c.execute();
conn.close();
}
}


②带输出参数的
 1:返回int
-------------------------带输出参数的----------------
alter procedure getsum
@n int =0,
@result int output
as
declare @sum int
declare @i int
set @sum=0
set @i=0
while @i<=@n begin
set @sum=@sum+@i
set @i=@i+1
end
set @result=@sum
-------------------在查询分析器中执行------------
declare @myResult int
exec getsum 100,@myResult output
print @myResult





------------在JAVA中调用---------------------
import java.sql.*;
public class ProcedureTest 
{
public static void main(String args[]) throws Exception
{
//加载驱动
DriverManager.registerDriver(new sun.jdbc.odbc.JdbcOdbcDriver());
//获得连接
Connection conn=DriverManager.getConnection("jdbc:odbc:mydata","sa","");

//创建存储过程的对象
CallableStatement c=conn.prepareCall("{call getsum(?,?)}");

//给存储过程的第一个参数设置值
c.setInt(1,100);

//注册存储过程的第二个参数
c.registerOutParameter(2,java.sql.Types.INTEGER);//java.sql.Types.INTEGER（类型必须写）

//执行存储过程
c.execute();

//得到存储过程的输出参数值
System.out.println (c.getInt(2));
conn.close();
}
}
 2:返回varchar
----------------存储过程带游标----------------
---在存储过程中带游标   使用游标不停的遍历orderid
create procedure CursorIntoProcedure
@pname varchar(8000) output
as
--定义游标
declare cur cursor for select orderid from orders
--定义一个变量来接收游标的值
declare @v varchar(5)
--打开游标
open cur
set @pname=''--给@pname初值
--提取游标的值
fetch next from cur into @v
while @@fetch_status=0
begin

set @pname=@pname+';'+@v
fetch next from cur into @v
end
print @pname
--关闭游标
close cur
--销毁游标
deallocate cur

------------执行存储过程--------------
exec CursorIntoProcedure ''

--------------JAVA调用------------------
import java.sql.*;
public class ProcedureTest 
{
public static void main(String args[]) throws Exception
{
//加载驱动
DriverManager.registerDriver(new sun.jdbc.odbc.JdbcOdbcDriver());
//获得连接
Connection conn=DriverManager.getConnection("jdbc:odbc:mydata","sa","");
CallableStatement c=conn.prepareCall("{call CursorIntoProcedure(?)}");
c.registerOutParameter(1,java.sql.Types.VARCHAR);

c.execute();

System.out.println (c.getString(1));
conn.close();
}
}


3:调用带游标的存储过程
游标在包中出现一次就好，type rsf_c is ref cursor;   procedure get_teacher(c1 out rs_c);不必要在包体中出现,包体中
open cl fir select * from sa.teacher;
调用时输出参数：cs.registerOutParameter(第一个参数，oracle.jdbc.oracleTypes.cursor)游标类型；结合ResultSet来遍历游标：rs=(ResultSet)cs.getObject(1);(1表示及一个参数，也可以是多个)

③删除数据的存储过程
------------------存储过程--------------------------

drop table 学生基本信息表

create table 学生基本信息表
(
StuID int primary key,
StuName varchar(10),
StuAddress varchar(20)
)
insert into   学生基本信息表 values(1,'三毛','wuhan')
insert into   学生基本信息表 values(2,'三毛','wuhan')
create table 学生成绩表
(
StuID int,
Chinese int,
PyhSics int
foreign key(StuID) references   学生基本信息表(StuID)
on delete cascade
on update cascade
) 
insert into   学生成绩表 values(1,99,100)
insert into   学生成绩表 values(2,99,100)

--创建存储过程 
create procedure delePro
@StuID int
as
delete from 学生基本信息表 where StuID=@StuID
--创建完毕
exec delePro 1   --执行存储过程
--创建存储过程
create procedure selePro
as
select * from 学生基本信息表
--创建完毕
exec selePro   --执行存储过程
------------------在JAVA中调用----------------
import java.sql.*;
public class ProcedureTest 
{
public static void main(String args[]) throws Exception
{
//加载驱动
DriverManager.registerDriver(new sun.jdbc.odbc.JdbcOdbcDriver());
//获得连接
Connection conn=DriverManager.getConnection("jdbc:odbc:mydata","sa","");

//创建存储过程的对象
CallableStatement c=conn.prepareCall("{call delePro(?)}");

c.setInt(1,1);

c.execute();

c=conn.prepareCall("{call selePro}");
ResultSet rs=c.executeQuery();

while(rs.next())
{
String Stu=rs.getString("StuID");
String name=rs.getString("StuName");
String add=rs.getString("StuAddress");

System.out.println ("学号:"+"     "+"姓名:"+"     "+"地址");
System.out.println (Stu+"     "+name+"   "+add);
}
c.close();
}
}


④修改数据的存储过程
---------------------创建存储过程---------------------
create procedure ModPro
@StuID int,
@StuName varchar(10)
as
update 学生基本信息表 set StuName=@StuName where StuID=@StuID


-------------执行存储过程-------------------------
exec ModPro 2,'四毛'
---------------JAVA调用存储过程--------------------
import java.sql.*;
public class ProcedureTest 
{
public static void main(String args[]) throws Exception
{
//加载驱动
DriverManager.registerDriver(new sun.jdbc.odbc.JdbcOdbcDriver());
//获得连接
Connection conn=DriverManager.getConnection("jdbc:odbc:mydata","sa","");

//创建存储过程的对象
CallableStatement c=conn.prepareCall("{call ModPro(?,?)}");

c.setInt(1,2);
c.setString(2,"美女");

c.execute();

c=conn.prepareCall("{call selePro}");
ResultSet rs=c.executeQuery();

while(rs.next())
{
String Stu=rs.getString("StuID");
String name=rs.getString("StuName");
String add=rs.getString("StuAddress");

System.out.println ("学号:"+"     "+"姓名:"+"     "+"地址");
System.out.println (Stu+"     "+name+"   "+add);
}
c.close();
}
}


⑤查询数据的存储过程(模糊查询)
-----------------存储过程---------------------
create procedure FindCusts
@cust varchar(10)
as
select customerid from orders where customerid 
like '%'+@cust+'%'
---------------执行---------------------------
execute FindCusts 'alfki'
-------------在JAVA中调用--------------------------
import java.sql.*;
public class ProcedureTest 
{
public static void main(String args[]) throws Exception
{
//加载驱动
DriverManager.registerDriver(new sun.jdbc.odbc.JdbcOdbcDriver());
//获得连接
Connection conn=DriverManager.getConnection("jdbc:odbc:mydata","sa","");
//创建存储过程的对象
CallableStatement c=conn.prepareCall("{call FindCusts(?)}");
c.setString(1,"Tom");

ResultSet rs=c.executeQuery();

while(rs.next())
{
String cust=rs.getString("customerid");        
System.out.println (cust);
}
c.close();
}
}

⑥增加数据的存储过程

------------存储过程--------------------
create procedure InsertPro
@StuID int,
@StuName varchar(10),
@StuAddress varchar(20)
as
insert into 学生基本信息表 values(@StuID,@StuName,@StuAddress)

-----------调用存储过程---------------
exec InsertPro 5,'555','555'
-----------在JAVA中执行-------------
import java.sql.*;
public class ProcedureTest 
{
public static void main(String args[]) throws Exception
{
//加载驱动
DriverManager.registerDriver(new sun.jdbc.odbc.JdbcOdbcDriver());
//获得连接
Connection conn=DriverManager.getConnection("jdbc:odbc:mydata","sa","");

//创建存储过程的对象
CallableStatement c=conn.prepareCall("{call InsertPro(?,?,?)}");
c.setInt(1,6);
c.setString(2,"Liu");
c.setString(3,"wuhan");

c.execute();

c=conn.prepareCall("{call selePro}");
ResultSet rs=c.executeQuery();

while(rs.next())
{
String stuid=rs.getString("StuID");        
String name=rs.getString("StuName");        
String address=rs.getString("StuAddress");        
System.out.println (stuid+"   "+name+"   "+address);
}
c.close();
}
}

⑦在JAVA中创建存储过程   并且在JAVA中直接调用
import java.sql.*;
public class ProcedureTest 
{
public static void main(String args[]) throws Exception
{
//加载驱动
DriverManager.registerDriver(new sun.jdbc.odbc.JdbcOdbcDriver());
//获得连接
Connection conn=DriverManager.getConnection("jdbc:odbc:mydata","sa","");

Statement stmt=conn.createStatement();
//在JAVA中创建存储过程
stmt.executeUpdate("create procedure OOP as select * from 学生成绩表");

CallableStatement c=conn.prepareCall("{call OOP}");

ResultSet rs=c.executeQuery();
while(rs.next())
{
String chinese=rs.getString("Chinese");

System.out.println (chinese);
}
conn.close();

}
}
