小编use*_*816的帖子

我正在尝试每周获取报告,以了解有多少人实际使用该产品的状态.

这是我目前的查询

select 
COUNT(*) as 'TotalPurchased',
SUM(case when date<= DATEADD(day, -7, GETDATE())THEN 1 ELSE 0 END) as 'week1' 
from #myreport

我希望输出为

Totalpurchased   week1  week2 week3 ..........so on
  82              80     14    16

它应该到年底.

我从上面的查询中获得输出仅一周.我正在使用sql 2008 r2环境从临时表中获取数据.

我正在尝试使用带有批处理脚本的sqlcmd删除数据库.我遇到的问题是如果myql数据库在sql中不可用,则代码不会进入错误处理程序块.

@echo off
@echo IF ELSE DEMO
sqlcmd -S <servername> -U <username> -P <password> -Q "DROP DATABASE Mytest"  
IF ERRORLEVEL 1 goto err_handler
goto done

:err_handler
echo handle the error here
goto end

:done 
echo script completion code here

:end
@echo %Message%
pause

它给出了以下输出:

IF ELSE DEMO
Msg 3701, Level 11, State 1, Server HERCULES, Line 1
Cannot drop the database 'Mytest', because it does not exist or you do not have permission.
script completion code here
ECHO is off. …
