function Get-DbaDbUdf { <# .SYNOPSIS Gets database User Defined Functions .DESCRIPTION Gets database User Defined Functions .PARAMETER SqlInstance The target SQL Server instance or instances .PARAMETER SqlCredential Allows you to login to SQL Server using alternative credentials .PARAMETER Database To get User Defined Functions from specific database(s) .PARAMETER ExcludeDatabase The database(s) to exclude - this list is auto populated from the server .PARAMETER ExcludeSystemUdf This switch removes all system objects from the UDF collection .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: Security, Database Author: Klaas Vandenberghe (@PowerDbaKlaas) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .EXAMPLE PS C:\> Get-DbaDbUdf -SqlInstance sql2016 Gets all database User Defined Functions .EXAMPLE PS C:\> Get-DbaDbUdf -SqlInstance Server1 -Database db1 Gets the User Defined Functions for the db1 database .EXAMPLE PS C:\> Get-DbaDbUdf -SqlInstance Server1 -ExcludeDatabase db1 Gets the User Defined Functions for all databases except db1 .EXAMPLE PS C:\> Get-DbaDbUdf -SqlInstance Server1 -ExcludeSystemUdf Gets the User Defined Functions for all databases that are not system objects (there can be 100+ system User Defined Functions in each DB) .EXAMPLE PS C:\> 'Sql1','Sql2/sqlexpress' | Get-DbaDbUdf Gets the User Defined Functions for the databases on Sql1 and Sql2/sqlexpress #> [CmdletBinding()] param ( [parameter(Mandatory, ValueFromPipeline)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [object[]]$Database, [object[]]$ExcludeDatabase, [switch]$ExcludeSystemUdf, [Alias('Silent')] [switch]$EnableException ) process { foreach ($instance in $SqlInstance) { try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $sqlcredential } catch { Stop-Function -Message "Error occured while establishing connection to $instance" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } $databases = $server.Databases | Where-Object IsAccessible if ($Database) { $databases = $databases | Where-Object Name -In $Database } if ($ExcludeDatabase) { $databases = $databases | Where-Object Name -NotIn $ExcludeDatabase } foreach ($db in $databases) { $UserDefinedFunctions = $db.UserDefinedFunctions if (!$UserDefinedFunctions) { Write-Message -Message "No User Defined Functions exist in the $db database on $instance" -Target $db -Level Verbose continue } if (Test-Bound -ParameterName ExcludeSystemUdf) { $UserDefinedFunctions = $UserDefinedFunctions | Where-Object { $_.IsSystemObject -eq $false } } $UserDefinedFunctions | ForEach-Object { Add-Member -Force -InputObject $_ -MemberType NoteProperty -Name ComputerName -value $server.ComputerName Add-Member -Force -InputObject $_ -MemberType NoteProperty -Name InstanceName -value $server.ServiceName Add-Member -Force -InputObject $_ -MemberType NoteProperty -Name SqlInstance -value $server.DomainInstanceName Add-Member -Force -InputObject $_ -MemberType NoteProperty -Name Database -value $db.Name Select-DefaultView -InputObject $_ -Property ComputerName, InstanceName, SqlInstance, Database, Schema, CreateDate, DateLastModified, Name, DataType } } } } end { Test-DbaDeprecation -DeprecatedOn "1.0.0" -EnableException:$false -Alias Get-DbaDatabaseUdf } } |
