Java对存储过程的调用方法

一:Java如何实现对存储过程的调用: A: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();

} }

B: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);

     //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(); } } C: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();

} } D: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();

} } E: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();

} } F: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();

} }

G: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();
