建立一个表：post，字段：ID(int,主键)，a1，a2，a3，a4，a5，a6
建立一个存储过程，代码如下：
ALTER proc [dbo].[GetDataSet]
@TableList Varchar(200)='*',--搜索表的字段,比如：’id，datatime，job‘，用逗号隔开
@TableName Varchar(100), --搜索的表名
@SelectWhere Varchar(500),--搜索条件，这里不用写where，比如：job=’teacher‘and class='2'
@SelectOrderId Varchar(20),--表主键字段名。比如：id
@SelectOrder Varchar(200)='', --排序，可以使用多字段排序但主键字段必需在最前面.也可以不写，比如：order by class asc
@intPageNo int=1, --页号
@intPageSize int=10 ,--每页显示数
@RecordCount int OUTPUT --总记录数(存储过程输出参数)
as
declare @TmpSelect NVarchar(600)
declare @Tmp NVarchar(600)
set nocount on--关闭计数
set @TmpSelect = 'select @RecordCount = count(*) from '+@TableName+' '+@SelectWhere
execute sp_executesql
@TmpSelect, --执行上面的sql语句
N'@RecordCount int OUTPUT' , --执行输出数据的sql语句，output出总记录数
@RecordCount OUTPUT
--if (@RecordCount = 0) --如果没有贴子，则返回零
--return 0
/*判断页数是否正确*/
if (@intPageNo - 1) * @intPageSize > @RecordCount --页号大于总页数，返回错误
return (-1)
set nocount off--打开计数
if @SelectWhere != ''
begin
set @TmpSelect = 'select top '+str(@intPageSize)+' '+@TableList+' from '+@TableName+' '+@SelectWhere+' and '+@SelectOrderId+' not in(select top '+str((@intPageNo-1)*@intPageSize)+' '+@SelectOrderId+' from '+@TableName+' '+@SelectWhere +' '+@SelectOrder+') '+@SelectOrder
end
else
begin
set @TmpSelect = 'select top '+str(@intPageSize)+' '+@TableList+' from '+@TableName+' '+@SelectOrderId+' not in(select top '+str((@intPageNo-1)*@intPageSize)+' '+@SelectOrderId+' from '+@TableName+' '+@SelectOrder+') '+@SelectOrder
end
execute sp_executesql @TmpSelect
return(@@rowcount)
