SQL Server and PowerShell Let’s Get Serious Did you remember to? Start VM’s? Start SQL instances on local machine (both!) Start SSMS? Bring up web site to show? Open source code to show? Delete the .sql files? Create an empty “AnotherDatabase” for demos? Start backup runner? Check scripts for hostname, instances, and restore point in time demos 11/18/2018

AGENDA Why using PowerShell will make your life more awesome SQL Server PowerShell Provider Code, code, and more code! 11/18/2018

Using PowerShell Will Make Your Life Awesome! “I don’t want to learn PowerShell because I don’t have time.” “Why would I waste time writing this in PowerShell when I can already do it in T-SQL?” Understanding PowerShell in general increases your worth. Helps you interact with System Administrators better. Useful for deploying code or system changes. Saves you a ton of time (automate all the things!). Core Servers laugh at your puny GUI. Let me know how you plan on automating things in Azure. 11/18/2018

The SQL Server PowerShell Provider SQLPS Module It’s where the awesome lives Provides a directory hierarchy for interacting with SQL Server NOT perfect, but: SSMS 2016 fixes A LOT of problems Be careful with multiple versions of SSMS/SQL Server installed on same machine Good news! Microsoft is finally working hard to get “proper” SQL Server PowerShell integration and cmdlets. New cmdlets already added, more coming. For more information, including cmdlets and SMO objects: https://msdn.microsoft.com/en-us/library/cc281947(v=sql.130).aspx Import the module Show the path Show databases, use get-member Show names and sizes 11/18/2018

Style Points Write scripts, not code Return objects where possible Let the provider do the work! Gross: Less Gross: Huh? Butter: [Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SMO") $SQLSvr = "." $ServerObject = new-object "Microsoft.SqlServer.Management.Smo.Server" $SQLSvr $Databases = $ServerObject.Databases Add-Type -AssemblyName "Microsoft.SqlServer.SMO,Version=13.0.0.0,Culture=neutral,PublicKeyToken=89845dcd8080cc91“ $SQLSvr = “localhost” $ServerObject = New-Object "Microsoft.SqlServer.Management.SMO.Server" $SQLSvr $Databases = $ServerObject.Databases $databases = Invoke-SQLCmd -ServerInstance localhost -Database master -Query "SELECT * FROM sys.Databases" $databases.Name Import-Module SQLPS $Databases = Get-ChildItem -Path "SQLSERVER:\SQL\LOCALHOST\DEFAULT\DATABASES" 11/18/2018

Let’s Just Do it! 11/18/2018

Real-World Example: Export Database Objects (not just tables) for DR purposes Why backup an entire reporting replica when you can just grab the good bits? Perfect for reporting environments Talk about the .Script() method, maybe bring up MSDN page if able? To File: .\Get-DatabaseObjects.ps1 -serverName localhost –instanceName sql2016 -databaseName AdventureWorks2014 -saveTo File -fileName C:\temp\Adventureworks2014_Objects.sql –Verbose To Database: .\Get-DatabaseObjects.ps1 -serverName localhost -instanceName sql2016 -databaseName AdventureWorks2014 -saveTo Database -repoServerName localhost -repoInstanceName sql2016 –repoDatabaseName Admin -repoSchemaName Repo -repoTableName ObjectsRepository –Verbose Create TWO new databases when you’re done, and run the generated script! 11/18/2018

Real-World Example: Dynamically Copy Database Tables From One Database to Another PowerShell makes it easy to iterate over a Database/Schema and script out objects while also copying the data. What about Foreign Keys? What about Indexes? Permissions? Good intro into PowerShell provider and SQL drive paths Refresh() method on tables… why? Create a new database .\Copy-DatabaseTables.ps1 -SourceServerName localhost -SourceInstanceName sql2014 -SourceDatabaseName AdventureWorks2014 -DestinationServerName localhost -DestinationDatabaseName Somedatabase -DestinationSchemaName Sales -WorkingDirectory C:\temp -noCheckConstraints –Verbose –WarningAction silentlycontinue 11/18/2018

Real-World Example: Managing Backups Managing backups in SQL server isn’t necessarily difficult, but being consistent can be. Using PowerShell you can keep your scripts unified across all servers for better naming conventions And you can use it to restore a database to a point in time by gathering all your log files together, too! .\Start-SQLRestore.ps1 -servername localhost -instanceName sql2016 -databaseName AdventureWorks2014 -fullBackupFileLocation C:\Temp\backups\localhost\AdventureWorks2014\Full -differentialBackupFileLocation C:\Temp\backups\localhost\AdventureWorks2014\Differential -logBackupFileLocation C:\Temp\backups\localhost\AdventureWorks2014\Log -toPointInTime "08/06/2016 3:00 PM" -Verbose -ErrorAction Stop Show how it detects broken chains 11/18/2018

Real-World Example: Auditing SQL Server Group Permissions Just who has access to that database? In an active directory environment, guess what? There’s a tool (and module!) for that… Great example about how you can marry multiple products together Install-windowsfeature -name AD-Domain-Services –IncludeManagementTools .\Start-SQLPermissionsAudit.ps1 -servername localhost -databaseName AdventureWorks2014 -Verbose | Export-Csv Users.txt -NoTypeInformation 11/18/2018

Wrapping Up PowerShell is a great tool that you should be using, or trying to use Not saying it should solve/replace all your tasks, just supplement them Helps blur the line between a SQL Server Professional/DevOps/Iteration Management/etc A more robust you = a more in-demand you 11/18/2018
