function Get-DbaDeprecatedFeature { <# .SYNOPSIS Displays information relating to deprecated features for SQL Server 2005 and above. .DESCRIPTION Displays information relating to deprecated features for SQL Server 2005 and above. .PARAMETER SqlInstance The target SQL Server instance .PARAMETER SqlCredential Login to the target instance using alternate Windows or SQL Login Authentication. Accepts credential objects (Get-Credential). .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: Deprecated Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaDeprecatedFeature .EXAMPLE PS C:\> Get-DbaDatabase -SqlInstance sql2008 -Database testdb, db2 | Get-DbaDeprecatedFeature Check deprecated features on server sql2008 for only the testdb and db2 databases .EXAMPLE PS C:\> Get-DbaDeprecatedFeature -SqlInstance sql2008, sqlserver2012 Check deprecated features for all databases on the servers sql2008 and sqlserver2012. .EXAMPLE PS C:\> Get-DbaDeprecatedFeature -SqlInstance sql2008 -Database TestDB Check deprecated features on server sql2008 for only the TestDB database .EXAMPLE PS C:\> Get-DbaDeprecatedFeature -SqlInstance sql2008 -Database TestDB -Threshold 20 Check deprecated features on server sql2008 for only the TestDB database, limiting results to 20% utilization of seed range or higher #> [CmdletBinding()] param ( [parameter(Position = 0, Mandatory, ValueFromPipeline)] [Alias("ServerInstance", "SqlServer", "SqlServers")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [switch]$EnableException ) begin { $sql = "SELECT SERVERPROPERTY('MachineName') AS ComputerName, ISNULL(SERVERPROPERTY('InstanceName'), 'MSSQLSERVER') AS InstanceName, SERVERPROPERTY('ServerName') AS SqlInstance, object_name, instance_name as DeprecatedFeature, object_name as ObjectName, instance_name as deprecated_feature, cntr_value as UsageCount FROM sys.dm_os_performance_counters WHERE object_name like '%Deprecated%' and cntr_value > 0 ORDER BY deprecated_feature" } process { foreach ($instance in $SqlInstance) { Write-Message -Level Verbose -Message "Attempting to connect to $instance" try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential -MinimumVersion 9 } catch { Stop-Function -Message "Failure" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } try { $server.Query($sql) | Select-DefaultView -Property ComputerName, InstanceName, SqlInstance, ObjectName, DeprecatedFeature, UsageCount } catch { Stop-Function -Message "Failure" -ErrorRecord $_ -Target $instance -Continue } } } } |
