I'm trying to connect to my database using PowerShell but it's not find it even though I can see it using SSMS.

I'm trying to follow the example MS provides here

Answer 1

If you are on the SQL Server where the database resides, then you can follow these steps to connect to a database in PowerShell

First you have to load the SQL Server PowerShell Module. This is achieved with the following simple command:

PS C:\> sqlps
Microsoft (R) SQL Server (R) PowerShell
Version 12.0.5557.0
Copyright (c) 2014 Microsoft. All rights reserved.

PS SQLSERVER:\> 

You have now loaded the SQL Powershell Module and have been switched to the SQLSERVER drive.

Let's see what we can retrieve from the system:

PS SQLSERVER:\> get-childitem

Name            Root                           Description
----            ----                           -----------
DAC             SQLSERVER:\DAC                 SQL Server Data-Tier Application
                                               Component
DataCollection  SQLSERVER:\DataCollection      SQL Server Data Collection
SQLPolicy       SQLSERVER:\SQLPolicy           SQL Server Policy Management
Utility         SQLSERVER:\Utility             SQL Server Utility
SQLRegistration SQLSERVER:\SQLRegistration     SQL Server Registrations
SQL             SQLSERVER:\SQL                 SQL Server Database Engine
SSIS            SQLSERVER:\SSIS                SQL Server Integration Services
XEvent          SQLSERVER:\XEvent              SQL Server Extended Events
DatabaseXEvent  SQLSERVER:\DatabaseXEvent      SQL Server Extended Events
SQLAS           SQLSERVER:\SQLAS               SQL Server Analysis Services


PS SQLSERVER:\>

That looks promising.

We'll switch into the SQL Server Database Engine (SQL) and see what we have:

PS SQLSERVER:\> cd SQL
PS SQLSERVER:\SQL> get-childitem

MachineName
-----------
SQLSERVER-NAME

Ok. Let's connect to the SQLSERVER-NAME instance and carry on researching (I used localhost in my example, because I am on the server itself):

PS SQLSERVER:\SQL> cd localhost
PS SQLSERVER:\SQL\localhost> get-childitem

Instance Name
-------------
DEFAULT

Switch to the DEFAULT instance:

PS SQLSERVER:\SQL\localhost> cd DEFAULT
PS SQLSERVER:\SQL\localhost\DEFAULT>

And retrieve a list of instance objects:

PS SQLSERVER:\SQL\localhost\DEFAULT> get-childitem
Audits
AvailabilityGroups
BackupDevices
Credentials
CryptographicProviders
Databases
Endpoints
JobServer
Languages
LinkedServers
Logins
Mail
ResourceGovernor
Roles
ServerAuditSpecifications
SystemDataTypes
SystemMessages
Triggers
UserDefinedMessages
PS SQLSERVER:\SQL\localhost\DEFAULT>

Ok, switch into the databases...

PS SQLSERVER:\SQL\localhost\DEFAULT> cd Databases
PS SQLSERVER:\SQL\localhost\DEFAULT\Databases> get-childitem

PS SQLSERVER:\SQL\localhost\DEFAULT\Databases>

Once you are in the correct database, you can then set of relevant CMD-lets.

PS SQLSERVER:\SQL\localhost\DEFAULT\Databases> cd StackExchange
PS SQLSERVER:\SQL\localhost\DEFAULT\Databases\StackExchange> cd Tables
PS SQLSERVER:\SQL\localhost\DEFAULT\Databases\StackExchange\Tables> Get-ChildItem

PS SQLSERVER:\SQL\localhost\DEFAULT\Databases\StackExchange\Tables>

You can then carry on from here.

Answer 2

Just follow the simple steps as mention below

[System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMO') | out-null 

$srv = new-object ('Microsoft.SqlServer.Management.Smo.Server') "LOCALHOST"  


#This sets the connection to mixed-mode authentication 

$srv.ConnectionContext.LoginSecure=$false; 



#This sets the login name 
$srv.ConnectionContext.set_Login("userid"); 



#This sets the password 
$srv.ConnectionContext.set_Password("PaSSw0rd") 

we can retrieve the list of databases running on the SQL Server instance by adding the code below.

$srv.Databases | Select name
