For the default instance specify 'MSSQLSERVER'. .PARAMETER SetFilePath Path to the T-SQL file that will perform Set action. .PARAMETER GetFilePath Path to the T-SQL file that will perform Get action. Any values returned by the T-SQL queries will also be returned by the cmdlet Get-DscConfiguration through the `GetResult` property. .PARAMETER TestFilePath Path to the T-SQL file that will perform 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 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.
