用了上面的这个分页存储过程，发现偶尔出现
无法移除＂ 'tempTablePage1 '＂，因为它在系统目录中不存在
这种错误．发生的频率十分少．但是不知道是什么bug?
[解决办法]
可能并发操作太频繁，导致判断的时候有这个表，而删除的时候已经不存在了。
[解决办法]
if exists (select 1 from sysobjects where id = object_id( 'tempTablePage1 ') and type = 'U ')=====改为下面语句试试：
if exists (select * from dbo.sysobjects where id = object_id(N '[tempTablePage1] ') and OBJECTPROPERTY(id, N 'IsUserTable ') = 1)
[解决办法]
临时表是在系统数据库tempdb的sysobjects表中，当断开本次链接时，自动从tempdb库中的sysobjects表中删除，它又不在当前所创建的数据库中
[解决办法]
use pubs
go
create table #a (a int)
use tempdb
go
select top 1 name from sysobjects
where type= 'u '
order by crdate desc
name

楼主可以使用@@ERROR来捕获错误发生在哪一个DROP 过程。
象楼主的这样，建议把tempTablePage1改成使用临时表#tempTablePage1，就如wangtiecheng(不知不为过，不学就是错！) 说的方法解决。
[解决办法]
1.临时表不用删除，只要断了连接就自动删除。。
2.创建临时表可能使Create Table ，也可以使用Select Into
[解决办法]
exec ( 'select a.* , identity(int,1,1) as NumberIndex into tempTablePage1 from ( ' + @SelectStatement + ' from ' + @FromStatement + ' where ' + @WhereStatement + ' order by ' + @OrderByExpression + ' ' + @AscOrDesc + ') as a ')
这里面的tempTablePage1 替换为临时表#tempTablePage1 ，并把之后的所有SQL都写到这个Exec 的动态脚本中。因为在Exec动态创建的临时表，在外部无法访问。
