SQLSERVER:通过sys.tables实现批量删表,或者回滚表

 1 begin try
 2     drop table #temp10
 3 end try
 4 begin catch
 5 end catch
 6 
 7 select 'drop/*truncate*/ table dbo.'+name as droptable,ROW_NUMBER() over(order by name) as rownumber 
 8 into #temp10
 9 from sys.tables where name like 'member%' and SCHEMA_NAME(schema_id)='dbo'
10 
11 select * from #temp10
12 
13 declare @rownumber int;
14 declare @records int;
15 declare @droptable  nvarchar(64);
16 
17 select @records=MAX(rownumber) from #temp10
18 
19 set @rownumber=1;
20 
21 while @rownumber<=@records 
22 begin 
23     select @droptable = droptable from #temp10 where rownumber=@rownumber
24     print @droptable
25     exec sp_executesql @droptable
26     
27     set @rownumber=@rownumber+1;
28 end

动态统计数据库，某表每秒插入记录量

 1 declare @records int;
 2   
 3 while 0=0
 4 begin 
 5     waitfor delay '00:00:01'   -- 每间隔1s，执行一次
 6    
 7     select @records=isnull(sum(t10.rows),0)
 8     from sys.partitions as t10 
 9         inner join sys.objects as t11 on t10.object_id=t11.object_id
10     where t11.name like 'member%' 
11     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
12     and t10.index_id>=2
13     
14     print @records
15 end
