function Set-DbaDbQueryStoreOption { <# .SYNOPSIS Configure Query Store settings for a specific or multiple databases. .DESCRIPTION Configure Query Store settings for a specific or multiple databases. .PARAMETER SqlInstance The target SQL Server instance or instances. .PARAMETER SqlCredential SqlCredential object used to connect to the SQL Server as a different user. .PARAMETER Database The database(s) to process - this list is auto-populated from the server. If unspecified, all databases will be processed. .PARAMETER ExcludeDatabase The database(s) to exclude - this list is auto-populated from the server .PARAMETER AllDatabases Run command against all user databases .PARAMETER State Set the state of the Query Store. Valid options are "ReadWrite", "ReadOnly" and "Off". .PARAMETER FlushInterval Set the flush to disk interval of the Query Store in seconds. .PARAMETER CollectionInterval Set the runtime statistics collection interval of the Query Store in minutes. .PARAMETER MaxSize Set the maximum size of the Query Store in MB. .PARAMETER CaptureMode Set the query capture mode of the Query Store. Valid options are "Auto" and "All". .PARAMETER CleanupMode Set the query cleanup mode policy. Valid options are "Auto" and "Off". .PARAMETER StaleQueryThreshold Set the stale query threshold in days. .PARAMETER WhatIf Shows what would happen if the command were to run .PARAMETER Confirm Prompts for confirmation of every step. For example: Are you sure you want to perform this action? Performing the operation "Changing Desired State" on target "pubs on SQL2016\VNEXT". [Y] Yes [A] Yes to All [N] No [L] No to All [S] Suspend [?] Help (default is "Y"): .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: QueryStore Author: Enrico van de Laar (@evdlaar) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Set-DbaQueryStoreOptions .EXAMPLE PS C:\> Set-DbaDbQueryStoreOption -SqlInstance ServerA\SQL -State ReadWrite -FlushInterval 600 -CollectionInterval 10 -MaxSize 100 -CaptureMode All -CleanupMode Auto -StaleQueryThreshold 100 -AllDatabases Configure the Query Store settings for all user databases in the ServerA\SQL Instance. .EXAMPLE PS C:\> Set-DbaDbQueryStoreOption -SqlInstance ServerA\SQL -FlushInterval 600 Only configure the FlushInterval setting for all Query Store databases in the ServerA\SQL Instance. .EXAMPLE PS C:\> Set-DbaDbQueryStoreOption -SqlInstance ServerA\SQL -Database AdventureWorks -State ReadWrite -FlushInterval 600 -CollectionInterval 10 -MaxSize 100 -CaptureMode all -CleanupMode Auto -StaleQueryThreshold 100 Configure the Query Store settings for the AdventureWorks database in the ServerA\SQL Instance. .EXAMPLE PS C:\> Set-DbaDbQueryStoreOption -SqlInstance ServerA\SQL -Exclude AdventureWorks -State ReadWrite -FlushInterval 600 -CollectionInterval 10 -MaxSize 100 -CaptureMode all -CleanupMode Auto -StaleQueryThreshold 100 Configure the Query Store settings for all user databases except the AdventureWorks database in the ServerA\SQL Instance. #> [CmdletBinding(SupportsShouldProcess)] param ( [parameter(Mandatory, ValueFromPipeline)] [DbaInstanceParameter[]]$SqlInstance, [PSCredential] $SqlCredential, [object[]]$Database, [object[]]$ExcludeDatabase, [switch]$AllDatabases, [ValidateSet('ReadWrite', 'ReadOnly', 'Off')] [string[]]$State, [int64]$FlushInterval, [int64]$CollectionInterval, [int64]$MaxSize, [ValidateSet('Auto', 'All')] [string[]]$CaptureMode, [ValidateSet('Auto', 'Off')] [string[]]$CleanupMode, [int64]$StaleQueryThreshold, [switch]$EnableException ) begin { $ExcludeDatabase += 'master', 'tempdb' } process { if (!$Database -and !$ExcludeDatabase -and !$AllDatabases) { Stop-Function -Message "You must specify a database(s) to execute against using either -Database, -ExcludeDatabase or -AllDatabases" return } if (!$State -and !$FlushInterval -and !$CollectionInterval -and !$MaxSize -and !$CaptureMode -and !$CleanupMode -and !$StaleQueryThreshold) { Stop-Function -Message "You must specify something to change." return } foreach ($instance in $SqlInstance) { try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential -MinimumVersion 13 } catch { Stop-Function -Message "Can't connect to $instance.
