SQL Server可按任意字段排序的分页存储过程(不用临时表的方法)

 CREATE PROCEDURE GetRecordFromPage
    @tblName      varchar(255),       -- 表名
    @fldName      varchar(255),       -- 字段名
    @PageSize     int = 10,           -- 页尺寸
    @PageIndex    int = 1,            -- 页码
    @IsCount      bit = 0,            -- 返回记录总数, 非 0 值则返回
    @OrderType    bit = 0,            -- 设置排序类型, 非 0 值则降序
    @strWhere     varchar(4000) = ''  -- 查询条件 (注意: 不要加 where)
AS
 
declare  @strSQL   varchar(6000)     -- 主语句
declare @strTmp   varchar(6000)     -- 临时变量
declare @strOrder varchar(6000)       -- 排序类型
