function Copy-DbaQueryStoreConfig { <# .SYNOPSIS Copies the configuration of a Query Store enabled database and sets the copied configuration on other databases. .DESCRIPTION Copies the configuration of a Query Store enabled database and sets the copied configuration on other databases. .PARAMETER Source Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2016 or higher. .PARAMETER SourceSqlCredential Allows you to login to servers using SQL Logins instead of Windows Authentication (AKA Integrated or Trusted). To use: $scred = Get-Credential, then pass $scred object to the -SourceSqlCredential parameter. Windows Authentication will be used if SourceSqlCredential 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 SourceDatabase Specifies the database to copy the Query Store configuration from. .PARAMETER Destination Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2016 or higher. .PARAMETER DestinationSqlCredential Allows you to login to servers using SQL Logins instead of Windows Authentication (AKA Integrated or 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 DestinationDatabase Specifies a list of databases that will receive a copy of the Query Store configuration of the SourceDatabase. .PARAMETER Exclude Specifies a list of databases which will NOT receive a copy of the Query Store configuration. .PARAMETER AllDatabases If this switch is enabled, the Query Store configuration will be copied to all databases on the destination instance. .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .PARAMETER Silent If this switch is enabled, the internal messaging functions will be silenced. .NOTES Author: Enrico van de Laar ( @evdlaar ) Tags: QueryStore 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-QueryStoreConfig .EXAMPLE Copy-DbaQueryStoreConfig -Source ServerA\SQL -SourceDatabase AdventureWorks -Destination ServerB\SQL -AllDatabases Copy the Query Store configuration of the AdventureWorks database in the ServerA\SQL instance and apply it on all user databases in the ServerB\SQL Instance. .EXAMPLE Copy-DbaQueryStoreConfig -Source ServerA\SQL -SourceDatabase AdventureWorks -Destination ServerB\SQL -DestinationDatabase WorldWideTraders Copy the Query Store configuration of the AdventureWorks database in the ServerA\SQL instance and apply it to the WorldWideTraders database in the ServerB\SQL Instance. #> [CmdletBinding(SupportsShouldProcess = $true)] param ( [parameter(Mandatory = $true, ValueFromPipeline = $true)] [DbaInstanceParameter]$Source, [PSCredential]$SourceSqlCredential, [parameter(Mandatory = $true, ValueFromPipeline = $true)] [object]$SourceDatabase, [parameter(Mandatory = $true, ValueFromPipeline = $true)] [DbaInstanceParameter[]]$Destination, [PSCredential]$DestinationSqlCredential, [object[]]$DestinationDatabase, [object[]]$Exclude, [switch]$AllDatabases, [switch]$Silent ) BEGIN { Write-Message -Message "Connecting to source: $Source." -Level Verbose try { $sourceServer = Connect-SqlInstance -SqlInstance $Source -SqlCredential $SourceSqlCredential } catch { Stop-Function -Message "Can't connect to $Source." -InnerErrorRecord $_ -Target $Source } } PROCESS { if (Test-FunctionInterrupt) { return } # Grab the Query Store configuration from the SourceDatabase through the Get-DbaQueryStoreConfig function $SourceQSConfig = Get-DbaQueryStoreConfig -SqlInstance $sourceServer -Database $SourceDatabase if (!$DestinationDatabase -and !$Exclude -and !$AllDatabases) { Stop-Function -Message "You must specify databases to execute against using either -DestinationDatabase, -Exclude or -AllDatabases." -Continue } foreach ($destinationServer in $Destination) { Write-Message -Message "Connecting to destination: $Destination." -Level Verbose try { $destServer = Connect-SqlInstance -SqlInstance $destinationServer -SqlCredential $DestinationSqlCredential } catch { Stop-Function -Message "Can't connect to $destinationServer." -InnerErrorRecord $_ -Target $destinationServer -Continue } # We have to exclude all the system databases since they cannot have the Query Store feature enabled $dbs = Get-DbaDatabase -SqlInstance $destServer -NoSystemDb if ($DestinationDatabase.count -gt 0) { $dbs = $dbs | Where-Object { $DestinationDatabase -contains $_.Name } } if ($Exclude.count -gt 0) { $dbs = $dbs | Where-Object { $exclude -notcontains $_.Name } } if ($dbs.count -eq 0) { Stop-Function -Message "No matching databases found.
