  CREATE PROCEDURE [dbo].[sp_insertStudent](@name char(10),@age int,@id int OUTPUT) AS
  insert into Students([Name],[Age]) values (@name,@age)
  select @id=@@IDENTITY
  GO

    try {
      pstmt = con.prepareCall("{call sp_insertStudent(?,?,?)}");
      pstmt.setString(1, "zengqingsong");
      pstmt.setInt(2, 22);

      pstmt.registerOutParameter(3, Types.INTEGER);
      pstmt.executeUpdate();

      int id = pstmt.getInt(3);
      System.out.println(id);
    }
  使用返回参数的例子：

  CREATE PROCEDURE [dbo].[sp_insertStudent](@name char(10),@age int,@id int OUTPUT) AS
  insert into Students([Name],[Age]) values (@name,@age)
  select @id=@@IDENTITY –测试输出参数
  return 30 –测试返回30
  GO

    try {
      pstmt = con.prepareCall("{?=call sp_insertStudent(?,?,?)}");
      pstmt.setString(2, "zengqingsong");
      pstmt.setInt(3, 22);

      pstmt.registerOutParameter(4, Types.INTEGER);
      pstmt.registerOutParameter(1, Types.INTEGER);
      int ret = pstmt.executeUpdate(); //执行影响的行数

      int ret2 = pstmt.getInt(1); //返回参数（输出参数）
      int id = pstmt.getInt(4); //输出参数
      System.out.println(ret);
      System.out.println(ret2);
      System.out.println(id);
    }
