sql server检查临时表是否存在

if   object_id('tempdb..##TEMPTABLE1')   is   not   null
drop   table   ##TEMPTABLE1

上面一种不检查类型，##TEMPTABLE1可能是view或procedure的名字，完整的检查如下

if   exists   (select   *   from   tempdb.dbo.sysobjects   where   id   =   object_id(N'tempdb..##TEMPTABLE1')   and   type='U')

drop   table   ##TEMPTABLE1
