因为项目需要,必须使用大量临时表,因此编写批量删除临时表的通用语句
代码如下:
use tempdb
if object_id('tempdb..#table') is not null drop table tempdb..#table
select name into tempdb..#table
from (select * from sysobjects where xtype='U') a where
a.name like '%test_select'
declare @table varchar(100),@count int
select @count=count(name) from tempdb..#table
while(@count>0)
begin
select top 1 @table=name from tempdb..#table
exec('
if object_id('''+@table+''') is not null drop table '+@table+'
delete from tempdb..#table where name='''+@table+'''
')
set @count=@count-1
end
drop table tempdb..#table
建议:尽量不要大量使用临时表,因为使用tempdb库会使系统的负载加大。
