SqlServer 统计用户量实例（按年，月，日分组）

 

知识在于积累。好记星不如烂笔头。代码如下：

 1 if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[GetUsersOfStatistical]') and OBJECTPROPERTY(id, N'IsProcedure') = 1) 
 2 drop procedure [dbo].[GetUsersOfStatistical] 
 3 go
 4 create proc GetUsersOfStatistical
 5 (
 6 @TimeType varchar(50),
 7 @Wherestr Varchar(3000)
 8 )
 9 as 
10 begin
11 declare @sqlstr varchar(max)
12 if(@TimeType='Year')
13 begin
14 set @sqlstr='select datename(year,CreateTime) as creatime,sum(case Str3 when 1 then 1 when 3 then 1 when 5 then 1 else 0 end ) as ygb ,sum(case Str3 when 0 then 1 when 2 then 1 when 4 then 1 else 0 end ) as wgb ,sum(1) as allcount from egb_user_audit ' +@Wherestr +' group by datename(year,CreateTime)'
15 end
16 else if(@TimeType='Month')
17 begin
18 set @sqlstr='select datename(year,CreateTime)+datename(month,CreateTime) as creatime,sum(case Str3 when 1 then 1 when 3 then 1 when 5 then 1 else 0 end ) as ygb ,sum(case Str3 when 0 then 1 when 2 then 1 when 4 then 1 else 0 end ) as wgb ,sum(1) as allcount from egb_user_audit ' +@Wherestr +' group by datename(year,CreateTime)+datename(month,CreateTime)'
19 end
20 else 
21 begin 
22 set @sqlstr='select Convert(varchar(10),CreateTime,120)as creatime,sum(case Str3 when 1 then 1 when 3 then 1 when 5 then 1 else 0 end ) as ygb ,sum(case Str3 when 0 then 1 when 2 then 1 when 4 then 1 else 0 end ) as wgb ,sum(1) as allcount from egb_user_audit ' +@Wherestr +' group by Convert(varchar(10),CreateTime,120)'
23 end
24 exec(@sqlstr);
25 end
26 
27 exec GetUsersOfStatistical '','where Str2 in (10001)'
