function Invoke-DbaDatabaseUpgrade { <# .SYNOPSIS Take a database and upgrades it to compatibility of the SQL Instance its hosted on. Based on https://thomaslarock.com/2014/06/upgrading-to-sql-server-2014-a-dozen-things-to-check/ .DESCRIPTION Updates compatibility level, then runs CHECKDB with data_purity, DBCC updateusage, sp_updatestats and finally sp_refreshview against all user views. .PARAMETER SqlInstance The SQL Server that you're connecting to. .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 autopopulated from the server. If unspecified, all databases will be processed. .PARAMETER ExcludeDatabase The database(s) to exclude - this list is autopopulated from the server .PARAMETER AllUserDatabases Run command against all user databases .PARAMETER Force Don't skip over databases that are already at the same level the instance is .PARAMETER NoCheckDb Skip checkdb .PARAMETER NoUpdateUsage Skip usage update .PARAMETER NoUpdateStats Skip stats update .PARAMETER NoRefreshView Skip view update .PARAMETER DatabaseCollection A collection of databases (such as returned by Get-DbaDatabase) .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 "Update database" 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 Author: Stephen Bennett, https://sqlnotesfromtheunderground.wordpress.com/ Tags: Shrink, Databases Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Invoke-DbaDatabaseUpgrade .EXAMPLE Invoke-DbaDatabaseUpgrade -SqlInstance PRD-SQL-MSD01 -Database Test Runs the below processes against the databases -- Puts compatibility of database to level of SQL Instance -- Runs CHECKDB DATA_PURITY -- Runs DBCC UPDATESUSAGE -- Updates all users statistics -- Runs sp_refreshview against every view in the database .EXAMPLE Invoke-DbaDatabaseUpgrade -SqlInstance PRD-SQL-INT01 -Database Test -NoRefreshView Runs the upgrade command skipping the sp_refreshview update on all views .EXAMPLE Invoke-DbaDatabaseUpgrade -SqlInstance PRD-SQL-INT01 -Database Test -Force If database Test is already at the correct compatibility, runs every necessary step .EXAMPLE Get-DbaDatabase -SqlInstance sql2016 | Out-GridView -Passthru | Invoke-DbaDatabaseUpgrade Get only specific databases using GridView and pass those to Invoke-DbaDatabaseUpgrade #> [CmdletBinding(SupportsShouldProcess)] Param ( [parameter(Position = 0)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [System.Management.Automation.PSCredential]$SqlCredential, [object[]]$Database, [object[]]$ExcludeDatabase, [switch]$NoCheckDb, [switch]$NoUpdateUsage, [switch]$NoUpdateStats, [switch]$NoRefreshView, [switch]$AllUserDatabases, [switch]$Force, [parameter(ValueFromPipeline)] [Microsoft.SqlServer.Management.Smo.Database[]]$DatabaseCollection, [Alias('Silent')] [switch]$EnableException ) process { if (Test-Bound -not 'SqlInstance', 'DatabaseCollection') { Write-Message -Level Warning -Message "You must specify either a SQL instance or pipe a database collection" continue } if (Test-Bound -not 'Database', 'DatabaseCollection', 'ExcludeDatabase', 'AllUserDatabases') { Write-Message -Level Warning -Message "You must explicitly specify a database.
