![]() For example UsageDT should be a datetime rather than a varchar(255). Some properties may not be mapped to the desired SQL data type. New-Xsd.ps1 -Object $du -ItemTag DiskUsage -Attribute UsageDT,SystemName,DeviceID -ChildItems VolumeName,SizeGB,F reeGB,PercentFree >Įxamine the XSD file produced by New-Xsd. Next run the following command from Powershell to create the XSD file diskusage.xsd: ![]() ![]() To create the XSD file you first need to assign our disk usage information to a the variable $du as shown below:: UsageDT,SystemName,DeviceID -ChildItems Volu meName,SizeGB,FreeGB,PercentFree > The following creates an XML file of the disk space information called diskusge.xml: Now you are ready to create XML and XSD files. The New-Xsd script is available in the Resources section below. The notation is dot space dot forward slash. Note: When you source a function you are simply loading the definition of the function into your current Powershell session, but not executing the function. Copy the function to a text file called XML.ps1, save and source the function from PowerShell as follows: The Powershell Team blog posted a function called New-XML in this blog entry entitled Using PowerShell to Generate XML Documents. Both of these tasks can be accomplished using a the New-XML and New-XSD Powershell scripts. The XML/SQLXMLBulkLoad method requires we convert the output to XML and generate an XSD schema file with SQLXML annotations. Note: SQLXML 4.0 is also available on the SQL 2005 installation CD, but is not installed by default. It is difficult to find SQLXML on the Microsoft site so here is a link which will take you to the x86 SQLXML 4.0 SP1 install package download at the time of this writing. Method 2: XML/XMLBulkLoadĪn additional setup task is required for this method, you'll need to download and install SQLXML. Recommendation: Use this method if your load process will benefit from staging the data in CSV files, when you are dealing with large data sets and when you know the data does not contain extra commas. Some data may have commas in the output which can wreak havoc on any load routines. Depending on the data you may need to perform additional edits including removing extra quote marks around strings and converting Boolean values from true/false to 0 or 1 representations. Some editing of the CSV file produced by Export-CSV is required. This method is the fastest method in terms of load speed when dealing with large data sets.Ĭons: Requires file management when the solution may not require staging the data. Pros: Export-CSV/BULK INSERT is the simplest method and uses natively available cmdlets and utilities. WITH (FIELDTERMINATOR = ',', ROWTERMINATOR = '\n')" Sqlcmd -S "Z002\SqlExpress" -E -Q "BULK INSERT FROM 'C:\Users\u00\bin\diskusage.csv' The following code uses the SQL Server command-line utility SQLCMD from PowerShell to execute the BULK INSERT command against the diskusage.csv file: The CSV file is ready to be imported into the SQL Server table created during setup. Get-WmiObject -computername "$ComputerName" Win32_LogicalDisk -filter "DriveType=3"įoreach | Set-Content. Save the Powershell code below to a file as Get-DiskUsage.ps1: The examples in this article use the following Powershell script to extract disk space information. Let's look at three methods to you can use to load data into SQL Server from Powershell. From PowerShell you will inevitably want to load command and script output into a database.
