function Copy-DbaServerTrigger { <# .SYNOPSIS Copy-DbaServerTrigger migrates server triggers from one SQL Server to another. .DESCRIPTION By default, all triggers are copied. The -ServerTrigger parameter is auto-populated for command-line completion and can be used to copy only specific triggers. If the trigger already exists on the destination, it will be skipped unless -Force is used. .PARAMETER Source Source SQL Server.You must have sysadmin access and server version must be SQL Server version 2000 or greater. .PARAMETER SourceSqlCredential Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use: $scred = Get-Credential, then pass $scred object to the -SourceSqlCredential parameter. Windows Authentication will be used if DestinationSqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials. To connect as a different Windows user, run PowerShell as that user. .PARAMETER Destination Destination Sql Server. You must have sysadmin access and server version must be SQL Server version 2000 or greater. .PARAMETER DestinationSqlCredential Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use: $dcred = Get-Credential, then pass this $dcred to the -DestinationSqlCredential parameter. Windows Authentication will be used if DestinationSqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials. To connect as a different Windows user, run PowerShell as that user. .PARAMETER ServerTrigger The Server Trigger(s) to process - this list is auto-populated from the server. If unspecified, all Server Triggers will be processed. .PARAMETER ExcludeServerTrigger The Server Trigger(s) to exclude - this list is auto-populated from the server .PARAMETER WhatIf Shows what would happen if the command were to run. No actions are actually performed. .PARAMETER Confirm Prompts you for confirmation before executing any changing operations within the command. .PARAMETER Force Drops and recreates the Trigger if it exists .PARAMETER Silent Use this switch to disable any kind of verbose messages .NOTES Tags: Migration Author: Chrissy LeMaire (@cl), netnerds.net Requires: sysadmin access on SQL Servers Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .LINK https://dbatools.io/Copy-DbaServerTrigger .EXAMPLE Copy-DbaServerTrigger -Source sqlserver2014a -Destination sqlcluster Copies all server triggers from sqlserver2014a to sqlcluster, using Windows credentials. If triggers with the same name exist on sqlcluster, they will be skipped. .EXAMPLE Copy-DbaServerTrigger -Source sqlserver2014a -Destination sqlcluster -ServerTrigger tg_noDbDrop -SourceSqlCredential $cred -Force Copies a single trigger, the tg_noDbDrop trigger from sqlserver2014a to sqlcluster, using SQL credentials for sqlserver2014a and Windows credentials for sqlcluster. If a trigger with the same name exists on sqlcluster, it will be dropped and recreated because -Force was used. .EXAMPLE Copy-DbaServerTrigger -Source sqlserver2014a -Destination sqlcluster -WhatIf -Force Shows what would happen if the command were executed using force. #> [CmdletBinding(DefaultParameterSetName = "Default", SupportsShouldProcess = $true)] param ( [parameter(Mandatory = $true)] [DbaInstanceParameter]$Source, [PSCredential] $SourceSqlCredential, [parameter(Mandatory = $true)] [DbaInstanceParameter]$Destination, [PSCredential] $DestinationSqlCredential, [object[]]$ServerTrigger, [object[]]$ExcludeServerTrigger, [switch]$Force, [switch]$Silent ) begin { $sourceServer = Connect-SqlInstance -SqlInstance $Source -SqlCredential $SourceSqlCredential $destServer = Connect-SqlInstance -SqlInstance $Destination -SqlCredential $DestinationSqlCredential $source = $sourceServer.DomainInstanceName $destination = $destServer.DomainInstanceName if ($sourceServer.VersionMajor -lt 9 -or $destServer.VersionMajor -lt 9) { Stop-Function -Message "Server Triggers are only supported in SQL Server 2005 and above.
