 /*<summary>************************************************************************************************************
 名称： GetPageRecords
 功能： 获取分页数据每页的数据或者数据的总共条数
 参数：
    input: @tblName     表名
           @fldName     用于排序的字段
    @PageSize    每页显示数据条数
    @PageIndex   页码
    @IsCount     返回记录总数 ，非 0 值则返回记录总数
    @OrderType   设置排序类型，非 0 值则降序
    @strWhere    查询条件（注意：不要加 where）
