function Get-DbaServerInstallDate { <# .SYNOPSIS Returns the install date of a SQL Instance and Windows Server. .DESCRIPTION This command returns: SqlInstallDate WindowsInstallDate (use -IncludeWindows) .PARAMETER SqlInstance The SQL Server that you're connecting to. .PARAMETER SqlCredential Credential object used to connect to the SQL Server using SQL Authentication as a different user .PARAMETER Credential Credential object used to connect to the SQL Server as a different Windows user .PARAMETER IncludeWindows Includes the Windows Server Install date information .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: Install Author: Mitchell Hamann (@SirCaptainMitch), mitchellhamann.com Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaServerInstallDate .EXAMPLE PS C:\> Get-DbaServerInstallDate -SqlInstance SqlBox1\Instance2 Returns an object with SQL Instance Install date as a string. .EXAMPLE PS C:\> Get-DbaServerInstallDate -SqlInstance winserver\sqlexpress, sql2016 Returns an object with SQL Instance Install date as a string for both SQLInstances that are passed to the cmdlet. .EXAMPLE PS C:\> 'sqlserver2014a', 'sql2016' | Get-DbaServerInstallDate Returns an object with SQL Instance Install date as a string for both SQLInstances that are passed to the cmdlet via the pipeline. .EXAMPLE PS C:\> Get-DbaServerInstallDate -SqlInstance sqlserver2014a, sql2016 -IncludeWindows Returns an object with the Windows Install date and the SQL install date as a string. .EXAMPLE PS C:\> Get-DbaCmsRegServer -SqlInstance sql2014 | Get-DbaServerInstallDate Returns an object with SQL Instance install date as a string for every server listed in the Central Management Server on sql2014 #> [CmdletBinding()] param ( [parameter(Mandatory, ValueFromPipeline)] [Alias("ServerInstance", "SqlServer", "ComputerName")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential] $SqlCredential, [PSCredential] $Credential, [Switch]$IncludeWindows, [Alias('Silent')] [switch]$EnableException ) process { foreach ($instance in $SqlInstance) { try { Write-Message -Level VeryVerbose -Message "Connecting to $instance" -Target $instance $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential } catch { Stop-Function -Message "Failed to process Instance $Instance" -ErrorRecord $_ -Target $instance -Continue } if ($server.VersionMajor -ge 9) { Write-Message -Level Verbose -Message "Getting Install Date for: $instance" $sql = "SELECT create_date FROM sys.server_principals WHERE sid = 0x010100000000000512000000" [DbaDateTime]$sqlInstallDate = $server.Query($sql, 'master', $true).create_date } else { Write-Message -Level Verbose -Message "Getting Install Date for: $instance" $sql = "SELECT schemadate FROM sysservers" [DbaDateTime]$sqlInstallDate = $server.Query($sql, 'master', $true).create_date } $WindowsServerName = $server.ComputerNamePhysicalNetBIOS if ($IncludeWindows) { try { [DbaDateTime]$windowsInstallDate = (Get-DbaCmObject -ClassName win32_OperatingSystem -ComputerName $WindowsServerName -Credential $Credential -EnableException).InstallDate } catch { Stop-Function -Message "Failed to connect to: $WindowsServerName" -Continue -Target $instance -ErrorRecord $_ } } $object = [PSCustomObject]@{ ComputerName = $server.ComputerName InstanceName = $server.ServiceName SqlInstance = $server.DomainInstanceName SqlInstallDate = $sqlInstallDate WindowsInstallDate = $windowsInstallDate } if ($IncludeWindows) { Select-DefaultView -InputObject $object -Property ComputerName, InstanceName, SqlInstance, SqlInstallDate, WindowsInstallDate } else { Select-DefaultView -InputObject $object -Property ComputerName, InstanceName, SqlInstance, SqlInstallDate } } } } |
