For the default instance specify 'MSSQLSERVER'. .PARAMETER GetQuery The full query that will perform the Get Action Any values returned by the T-SQL queries will also be returned by the cmdlet Get-DscConfiguration through the `GetResult` property. .PARAMETER TestQuery The full query that will perform the Test Action Any script that does not throw an error or returns null is evaluated to true. The cmdlet `Invoke-SqlCmd` treats T-SQL Print statements as verbose text, and will not cause the test to return false. .PARAMETER SetQuery The full query that will perform the Set Action .PARAMETER ServerName Specifies the host name of the SQL Server to be configured. Default value is the current computer name. .PARAMETER Credential The credentials to authenticate with, using SQL Authentication. To authenticate using Windows Authentication, assign the credentials to the built-in parameter `PsDscRunAsCredential`. If both parameters `Credential` and `PsDscRunAsCredential` are not assigned, then SYSTEM account will be used to authenticate using Windows Authentication. .PARAMETER Variable Specifies, as a string array, a `Invoke-SqlCmd` scripting variable for use in the `Invoke-SqlCmd` script, and sets a value for the variable. Use a Windows PowerShell array to specify multiple variables and their values. For more information how to use this, please go to the help documentation for [`Invoke-SqlCmd`](https://docs.microsoft.com/en-us/powershell/module/sqlserver/Invoke-SqlCmd). .PARAMETER DisableVariables Specifies, as a boolean, whether or not PowerShell will ignore `Invoke-SqlCmd` scripting variables that share a format such as $(variable_name). For more information how to use this, please go to the help documentation for [`Invoke-SqlCmd`](https://docs.microsoft.com/en-us/powershell/module/sqlserver/Invoke-SqlCmd). .PARAMETER QueryTimeout Specifies, as an integer, the number of seconds after which the T-SQL script execution will time out. In some SQL Server versions there is a bug in `Invoke-SqlCmd` where the normal default value 0 (no timeout) is not respected and the default value is incorrectly set to 30 seconds. .PARAMETER Encrypt Specifies how encryption should be enforced when using command `Invoke-SqlCmd`. When not specified, the default value is `Mandatory`. This value maps to the Encrypt property SqlConnectionEncryptOption on the SqlConnection object of the Microsoft.Data.SqlClient driver. This parameter can only be used when the module SqlServer v22.x.x is installed. .OUTPUTS Hash table containing key 'GetResult' which holds the value of the result from the SQL script that was ran from the parameter 'GetQuery'. #> function Get-TargetResource { [System.Diagnostics.CodeAnalysis.SuppressMessageAttribute('SqlServerDsc.AnalyzerRules\Measure-CommandsNeededToLoadSMO', '', Justification='The command Import-SqlDscPreferredModule is implicitly called in Invoke-SqlScript')] [CmdletBinding()] [OutputType([System.Collections.Hashtable])] param ( [Parameter(Mandatory = $true)] [System.String] $InstanceName, [Parameter(Mandatory = $true)] [System.String] $GetQuery, [Parameter(Mandatory = $true)] [System.String] $TestQuery, [Parameter(Mandatory = $true)] [System.String] $SetQuery, [Parameter()] [ValidateNotNullOrEmpty()] [System.String] $ServerName = (Get-ComputerName), [Parameter()] [System.Management.Automation.PSCredential] [System.Management.Automation.Credential()] $Credential, [Parameter()] [System.UInt32] $QueryTimeout, [Parameter()] [System.String[]] $Variable, [Parameter()] [System.Boolean] $DisableVariables, [Parameter()] [ValidateSet('Mandatory', 'Optional', 'Strict')] [System.String] $Encrypt ) Write-Verbose -Message ( $script:localizedData.ExecutingGetQuery -f $InstanceName, $ServerName ) $serverInstance = ConvertTo-ServerInstanceName -InstanceName $InstanceName -ServerName $ServerName $invokeParameters = @{ Query = $GetQuery ServerInstance = $serverInstance Credential = $Credential Variable = $Variable DisableVariables = $DisableVariables QueryTimeout = $QueryTimeout Verbose = $VerbosePreference ErrorAction = 'Stop' } if ($PSBoundParameters.ContainsKey('Encrypt')) { $invokeParameters.Encrypt = $Encrypt } $result = Invoke-SqlScript @invokeParameters $getResult = Out-String -InputObject $result $returnValue = @{ ServerName = [System.String] $ServerName InstanceName = [System.String] $InstanceName GetQuery = [System.String] $GetQuery TestQuery = [System.String] $TestQuery SetQuery = [System.String] $SetQuery Credential = [System.Object] $Credential QueryTimeout = [System.UInt32] $QueryTimeout Variable = [System.String[]] $Variable DisableVariables = [System.Boolean] $DisableVariables GetResult = [System.String[]] $getResult Encrypt = [System.String] $Encrypt } return $returnValue } <# .SYNOPSIS Executes the Set-query. .PARAMETER InstanceName Specifies the name of the SQL Server Database Engine instance.
