dbatools.io = command-line SQL Server Management Studio

This post is part of the series showing practical usage examples. The main post covering links to all posts can be found here: dbatools.io = command-line SQL Server Management Studio: Table of contents.

dbatools commands used in this post:

Connect to the Database Engine

It is possible in dbatools to create a server object and reuse it without providing the credentials and connecting to the instance again and again.



# set the variables
$SqlInstance = "localhost:1433"
$User = "sa"
$PWord = ConvertTo-SecureString -String "<YourStrong@Passw0rd>" -AsPlainText -Force

# create the credential object
$Credential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $User, $PWord

# create the server connection object
$server = Connect-DbaInstance -SqlInstance $SqlInstance -SqlCredential $Credential

# additionally, see the server object

ComputerName Name           Product              Version   HostPlatform IsAzure IsClustered ConnectedAs
------------ ----           -------              -------   ------------ ------- ----------- -----------
localhost    localhost,1433 Microsoft SQL Server 14.0.3048 Linux        False   False       sa         

Execute a simple query

Once the connection is established you can run the query.



# reuse connection object created before
Invoke-DbaQuery -SqlInstance $server -Query "SELECT @@version"

# or reuse the credential object instead
Invoke-DbaQuery -SqlInstance "localhost,1433" -SqlCredential $Credential -Query "SELECT @@version"

# when AD auth in use, simply connect to the instance without server object
Invoke-DbaQuery -SqlInstance "localhost:1433" -Query "SELECT @@version" 

# save outputs as PowerShell object
$output = Invoke-DbaQuery -SqlInstance $server -Query "SELECT @@version"

# and... see them in the grid (with a pipeline)
$output | Out-GridView

Save results as…

Once you’ve got your results out, these can be saved as CSV or TXT file.



# or... save to a TXT file
$output | Out-File -FilePath .\output.txt

# or to a CSV file
$output | Export-Csv -Path .\output.csv -NoTypeInformation

# or to any table (dbatools)
$output|Write-DbaDbTableData -SqlInstance $server -Table tempdb.dbo.customers -AutoCreateTable

I hope that makes the whole command-line SQL Server Management Studio thing clearer. Next week I am going to show you how to see the SQL Server objects via dbatools.

Thank you,
