java+sql server+CallableStatement调用存储过程三种情况

java+sql server+CallableStatement调用存储过程三种情况

在JSP页面中进行测试，代码如下：

<% @ page contentType = " text/html;charset=gb2312 " %>
<% @ page  import = " java.sql.* " %>
< html >
     < body >
         <%
                    Class.forName( " com.microsoft.jdbc.sqlserver.SQLServerDriver " )
                    .newInstance();
            String url  =   " jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=pubs " ;
             // pubs为你的数据库的
            String user  =   " sa " ;
            String password  =   "" ;
            Connection conn  =  DriverManager.getConnection(url, user, password);
             // 不带参数的存储过程，并且返回结果集
            CallableStatement stmt  =  conn.prepareCall( " {call ghy_proc} " );
            stmt.execute();
            ResultSet rs  =  stmt.getResultSet();
             while  (rs.next())  {
                out.println(rs.getString(1));
            }
            out.println( " <br> " );

             // 带参数的存储过程，并且返回值
            stmt  =  conn.prepareCall( " {call ghy_proc_return(?,?)} " );
            stmt.registerOutParameter( 1 , Types.INTEGER);
            stmt.registerOutParameter( 2 , Types.INTEGER);
            stmt.setInt( 1 ,  10 );
            stmt.setInt( 2 ,  10 );
            stmt.execute();
            out.println( " 加1的值是： "   +  stmt.getString( 1 )  +   " <br> " );
            out.println( " 减1的值是： "   +  stmt.getString( 2 )  +   " <br> " );

             // 带参数的存储过程，并且返回结果集
            stmt  =  conn.prepareCall( " {call ghy_proc_var(?)} " );
            stmt.setInt( 1 ,  14 );
            stmt.execute();
            rs  =  stmt.getResultSet();
             while  (rs.next())  {
                out.println("job_id value is：" + rs.getString(1) + "<br>");
                out.println("job_desc value is：" + rs.getString(2) + "<br>");
            }
         %>
     </ body >
</ html >

三个SQL Server 2000存储过程如下：

CREATE   PROCEDURE  ghy_proc 
AS  
select   *   from  jobs
GO

CREATE   PROCEDURE  ghy_proc_return ( @max   int  output, @min   int  output)
AS  
select   @max = @max + 1
select   @min = @min - 1
GO

CREATE   PROCEDURE  ghy_proc_var  ( @id   int )
AS
select   *   from  jobs  where  job_id = @id
GO

告诉自己：标准SQL语法和概念很重要，以后要强化这些。
