我有以下查询:

 select 
    C.ClientID,
    C.FirstName + ' ' + C.LastName as ClientName,
    CAST(V.StartDate as date) as VisitDate,
    count(*) as 'Number of Visits'
 from
    Visit V
 Inner Join Client C on
    V.ClientID = C.ClientID
 group by 
    C.ClientID,
    C.FirstName + ' ' + C.LastName,
    CAST(V.StartDate as date)
 having
    count(*) > 3
 order by
    C.ClientID, 
    CAST(V.StartDate as date)

给出了以下结果(如果有人想知道,名字是假的)

 ClientID   ClientName            VisitDate      Number of Visits

我目前有以下查询:

select 
    DATEADD(MONTH, DATEDIFF(MONTH, 0, StartDate), 0) as MonthYear, count(*) as Count
from 
    visit
where 
    StartDate >= DATEADD(year,-1,GETDATE())
    and clientid = 142
group by  
    DATEADD(MONTH, DATEDIFF(MONTH, 0, StartDate), 0)

返回以下结果:

我也有以下查询:

我有以下脚本需要从 Azure 存储容器中删除超过 7 天并且突然停止工作的文件：

$StorageAccountName = "#"
$StorageAccountKey = "#"
$ContainerName = "#"
$CleanupOlderThanDays = [DateTime]::UtcNow.AddDays(-7)
$FolderName = "Daily"

$Ctx = New-AzureStorageContext -StorageAccountName $StorageAccountName -StorageAccountKey $StorageAccountKey
Get-AzStorageBlob -Container "$ContainerName" -Context $Ctx -Prefix $FolderName/ | Where-Object { $_.LastModified.UtcDateTime -lt $CleanupOlderThanDays } |Remove-AzStorageBlob

它现在失败并出现以下错误：

PS C:\backupcopy> .\remove_files_daily.ps1

same script or runbook. If you are running PowerShell in an environment you control you …

我已经将以下代码放在一起,似乎工作得很好.但是,我需要将它放在存储过程中,但是我收到以下错误:

过程,函数或触发器中不允许使用use语句

有人知道一个解决方法吗？

CREATE TABLE #TableRowCounts1
(
      [TableName] VARCHAR(128), 
      [RowCount] INT
) 

CREATE TABLE #TableRowCounts2
(
      [TableName] VARCHAR(128), 
      [RowCount] INT
) 

use Database1
GO

INSERT INTO #TableRowCounts1
(
      [TableName], 
      [RowCount]
      )
EXEC sp_MSforeachtable 
      'SELECT ''?'' 
      [TableName], 
      COUNT(*) [RowCount] 
      FROM ?'

use Database2
GO

INSERT INTO #TableRowCounts2
(
      [TableName], 
      [RowCount]
      )
EXEC sp_MSforeachtable 
      'SELECT ''?'' 
      [TableName], 
      COUNT(*) [RowCount] 
      FROM ?'

我在数据流区域内有以下内容.我遇到的问题是,即使结果为0,它仍然在创建文件.

谁能看到我在这里做错了什么？

我有以下查询,它证明非常昂贵,并需要6-8秒执行.查看执行计划,SORT操作的成本为79%.我可以在这里得到任何改进吗？

我很快就重新设计了我的网站,所有网址都在不断变化.这就是我到目前为止所做的一切http://cricketweb.net/new-design%20htaccess

我所做的一些研究表明,.htaccess文件中的这么多行会使性能降低很多.

我问我的托管服务提供商,他们说:

"您的信息是正确的,将这么多重定向添加到您的.htaccess会显着减慢您的网站的加载时间.不幸的是,将它们添加到Apache conf在cPanel服务器上不是一个好主意.cPanel对conf进行了编辑定期提交文件,可能不适合您的编辑.我建议首先重新评估重写模式.例如,如果domain1.com有文件夹a,b和c,并且您想将访问者发送到domain1.com/a到domain2 .com/a,b和c相同,这可以通过1次重写规则来实现.不幸的是,如果URL的方式不一致,比如你想将访问者发送到domain1.com/a到domain2.com/ asdf和访问domain1.com/b到domain2.com/zxcv的访问者,我们可能需要考虑使用此域的特殊规则编辑您的apache preconf文件,所以请告诉我你是否可以通过合并它们来缩小数字规则."

问题是我看不出如何巩固这些301.

有没有人有任何建议http://cricketweb.net/new-design%20htaccess？

我通过 Azure 中的 .NET 应用程序随机收到此错误消息。

关于该错误的可用信息似乎非常有限，我想知道是否有人知道可能是什么原因造成的？

它似乎是在调用某个存储过程时发生的，但它真的很难重新创建并且随机发生。

我有一个当前按年份拆分的分区方案设置。我正在尝试为明年创建一个新分区：

ALTER PARTITION SCHEME psYearlyPartition_Log

    NEXT USED Year7FileGroup;

ALTER PARTITION FUNCTION pfYearlyPartition_Log()

    SPLIT RANGE('20190101');

然而，这运行了很多小时并且没有完成。有谁知道为什么会发生这种情况，因为似乎还没有任何 2019 年的数据？

最后一个分区是从 2016-01-01 到今天。

我在这篇文章的底部运行了查询，结果如下：

 CREATE PARTITION FUNCTION [pfYearlyPartition](datetime) AS RANGE LEFT FOR VALUES('2012-01-01T00:00:00','2013-01-01T00:00:00','2014-01-01T00:00:00','2015-01-01T00:00:00','2016-01-01T00:00:00');
