c#下oracle分页方法

上次在网上抄的oracle分页存储过程不好使--~！，只能主键排序

无奈我写不出那么复杂的存储过程。。。用程序凑吧o(∩_∩)o ：

  /// <summary>
        /// 分页绑定
        /// </summary>  
        /// <param name="table">表名</param>
        /// <param name="where">要加载的条件</param>
        /// <param name="column">查询的列，比如：*或者code,name</param>
        /// <param name="order">排序字段，比如：code desc或者code asc</param>
        /// <param name="mPageSize">每页大小</param> 
        /// <param name="mPageIndex">查询第几页</param> 
        /// <param name="recount">out形式参数，返回记录总数</param>
        /// <returns>返回的是游标形式的数据集</returns> 
        public static DataSet PageBind(string table, string where, string column, string order, int mPageSize, int mPageIndex,out int recount)
        {
            StringBuilder sb = new StringBuilder(57);

            sb.Append("select count(1) from " + table);

            if (where.Length > 0)
            {
                sb.Append(" where " + where);
            }

            object _o = ExecuteSql_obj(sb.ToString());

            recount = Convert.ToInt32(_o);

            sb = new StringBuilder(500);

            sb.Append(" select * from ( select temp_b.*,rownum rk from (select " + column + " from " + table);

            if (where.Length > 0)
            {
                sb.Append(" where " + where);

            }
            if (order.Length > 0)
            {
                sb.Append(" order by " + order);
            }

            sb.Append(" ) temp_b where rownum<" + (mPageIndex * mPageSize + 1) + ") s where  s.rk> " + mPageSize * (mPageIndex - 1));

            DataSet ds = null;

            ds = Query(sb.ToString());

            return ds;
        }

     /// <summary>
        /// 执行查询语句，返回DataSet
        /// </summary>
        /// <param name="SQLString">查询语句</param>
        /// <returns>DataSet</returns>
        public static DataSet Query(string SQLString)
        {
            using (OracleConnection connection = new OracleConnection(connectionString))
            {
                DataSet ds = new DataSet();
                try
                {
                    connection.Open();
                    OracleDataAdapter command = new OracleDataAdapter(SQLString, connection);
                    command.Fill(ds, "ds");
                }
                catch (System.Data.OracleClient.OracleException ex)
                {
                    throw new Exception(ex.Message);
                }
                return ds;
            }
        }
