SQLSERVER:通过sys.tables实现批量删表,或者回滚表

 begin try
     drop table #temp10
 end try
 begin catch
 end catch

 select 'drop/*truncate*/ table dbo.'+name as droptable,ROW_NUMBER() over(order by name) as rownumber
 into #temp10
 from sys.tables where name like 'member%' and SCHEMA_NAME(schema_id)='dbo'

 select * from #temp10

 declare @rownumber int;
 declare @records int;
 declare @droptable  nvarchar(64);

 select @records=MAX(rownumber) from #temp10

 set @rownumber=1;

 while @rownumber<=@records
 begin
     select @droptable = droptable from #temp10 where rownumber=@rownumber
     print @droptable
     exec sp_executesql @droptable

     set @rownumber=@rownumber+1;
 end

动态统计数据库，某表每秒插入记录量

 declare @records int;

 while 0=0
 begin
     waitfor delay '00:00:01'   -- 每间隔1s，执行一次

     select @records=isnull(sum(t10.rows),0)
     from sys.partitions as t10
         inner join sys.objects as t11 on t10.object_id=t11.object_id
     where t11.name like 'member%'
     and t10.partition_number=2 -- 当前数据插入到那个分区了,就写那个分区.如果没有分区,该条件可以不加
     and t10.index_id>=2

     print @records
 end
