java存储过程调用 MSSQL

存储过程：

--call MyProc(?,?,?)
alter proc MyProc
(@id int,
 @customerid nchar(5) output,
 @employeeid int output
)as
begin
 select @customerid=customerid,@employeeid=employeeid from orders
 where orderid=@id
end
go

declare
@cu char(5),
@em int
exec MyProc 10248,@cu output,@em output
print(cast(@em as char(5))+@cu)

 

 

 

 

以下是java调用存储过程：

import java.sql.*;

public class Study
{
 private Connection con;
 public  ResultSet  re;
 private CallableStatement callsta;
 private String str;
 private String use="sa";
 private String pwd="sa";
 
 public Study()
 {
 try{
   //连接数据库驱动
   Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
   String str="jdbc:microsoft:sqlserver://localhost:1433;databasename=northwind";
   con=DriverManager.getConnection(str,use,pwd);
   
   //设置存储过程参数
   String st="{call MyProc(?,?,?)}";
   callsta=con.prepareCall(st);
   callsta.setInt(1,10248);
   callsta.registerOutParameter(2,Types.VARCHAR);
   callsta.registerOutParameter(3,Types.INTEGER);
   
   //测试调用执行成功与否
   System.out.println(callsta.execute());
   
   //循环输出调用存储过程的记录结果
   if(callsta.execute()==true)
   {
    re=callsta.getResultSet();
    while(re.next())
    {
     System.out.println(re.getInt(1)+" "+re.getString(2)+" "+re.getInt(3));
    }
   }
   else{System.out.println("dfas");}
 }
   catch(Exception e){e.printStackTrace();}
 }

 public static void main(String[] age)
 {
  Study study=new Study();
 }
}
