How to autostart and instance of MSSQLLocalDB (Microsoft SQL Express 2016) - sql-server

Is is possible to autostart an instance of the Microsoft SQL Server Express 2016.
This is currently on a Windows 10 system.
When I run sqllocaldb.exe info I get:

Everything works fine, except that I have to manually start it everytime.
*for those wanting to know how to do this the command line string is
command line screenshot starting MSSQLLocalDB
Or if you cannot see that picture then: sqllocaldb start mssqllocaldb
Reiterating my question: Is it possible to start this at system boot up?

Make a batch file containing only the command starting SQL Server Express and add a shortcut to it in the Windows Startup folder.

Unable to connect LocalDB from Visual Studio 2019

I had recently installed Visual Studio 2019. I wanted to add a database connection in VS but unfortunately, the VS does not detect the default instance of LocalDB, which I assume comes out of the box when installing VS (as it used to come with earlier version of VS).
I was trying to use the localdb to work with entity framework. I had no issue with VisualStuio 2017 but with new installation I cannot list out the localdb instance in database connection window.
I tried running the command SQLLOCALDB INFO in command line, where I got MSSQLLOCALDB as a result. I even tried running the command SQLLOCALDB START MSSQLLOCALDB. After execution of the command, I get the result that "LocalDB instance "MSSQLLocalDB" started.". However, I am still not able to list/connect it via VS (Tools>>Connect to database).
Is there any additional steps specific to VS2019 that I need to follow in order to establish the connection with LocalDB or do I need to explicitly install the express version of MSSQL server.
Use
(localdb)\MMSQLLocalDB
also
(localdb)\ProjectsV13

Running ms sql local db express

I installed Microsoft SQL Server Express localDB. Now I want to run it, and according to this tutorial:
https://www.mssqltips.com/sqlservertip/2694/getting-started-with-sql-server-2012-express-localdb/
I run (in cmd line):
SqlLocalDb info
then I get in cmd line: SqlLocalDb is not recognized as an internal or external command
How to fix it? Probbaly I have to add somethink to PATH variable?
It's strange that the installer didn't add it to your PATH already, but ignoring that - can you go to your C:\Program Files (might be in the x86 folder as well), find where the program was installed, and look for "SqlLocalDb.exe"? This is what would be executed when you run SqlLocalDb from the command line.
If you find it, open the command line at that location and try to run that command. (Tip: You can hold Shift and right click in the empty space in that window, and the right-click menu will contain "Open command window here".)
If that works, you can add that location to your PATH so that you don't have to be in that folder or specify the location.
I had the same problem, and the reason was I had SQL Server Management Studio, but I didn´t have installed the SQL Server.
I downloaded it from the Microsoft website and worked just fine. This is the Spanish version: https://www.microsoft.com/es-mx/sql-server/sql-server-downloads
restart your computer, it worked like that for me.
I had this issue and installing Microsoft SQL Server Express Localdb seemed to have fixed it.

How do you manually start SQL Server 2014?

During installation, I opted for manual startup of my SQL Server 2014 instance. The official MS documentation states that you should enter the following command into a command prompt to start it:
sqlservr
I tried that, as well as
sqlservr.exe
However, the command is not recognized, and running the command prompt in administrator mode doesn't work either. How do I manually start SQL Server 2014?
Generally you should use net start MSSQLSERVER command to run service, and not executable file you've mentioned.
In most cases, the sqlservr.exe program is only used for troubleshooting or major maintenance.
Also it makes sense where exactly this executable is located.
For the default instance, run sqlservr from the \MSSQL\Binn directory. For a named instance, run sqlservr from the \MSSQL$instance_name\Binn directory.
When SQL Server is started from the command prompt with sqlservr.exe, SQL Server does not start as a service, so you cannot stop SQL Server using net commands.
See MSDN article about starting and stopping SQL Server and sqlservr.exe related article.

How can I install the Northwind database into SQL Server Local DB?

I found the following link
Installing the Northwind Sample Database
However I am still not clear on the process. This talks about Server 2000 and MSDE 2000 but what I need is for the new SQL Server Local DB.
Has anyone else had to do this and found any instructions on how to proceed?
So, I can't seem to find a way of attaching an existing DB file to a LocalDB instance from inside visual studio (creating a new DB seems to be the only option), but you can do it via management studio by doing the following:
Step 1 - Find out the instance name of the LocalDB
Open a command prompt and run (the location may be slightly different depending on your install location):
C:\Program Files\Microsoft SQL Server\110\Tools\Binn>SqlLocalDB.exe
info
This will list all the instances of LocalDB, find the one you're interested in, VS2012 installed one for me called v11.0 (which I will use for my example)
Step 2 - Start the LocalDB instance
Again in your command prompt run the following:
C:\Program Files\Microsoft SQL Server\110\Tools\Binn>SqlLocalDB.exe
start v11.0
This will start the LocalDB instance and allow us to get the connection info
Step 3 - Get the name of the named pipe to connect to (pipe name changes every restart)
Another command prompt job:
C:\Program Files\Microsoft SQL Server\110\Tools\Binn>SqlLocalDB.exe
info v11.0
This will then return information about the instance, including the following line:
Instance pipe name: np:\.\pipe\LOCALDB#A6F550C6\tsql\query
Step 4 - Connect via management studio and attach the database
Open management studio and in the server box connect to the named pipe (windows auth) e.g. :
\.\pipe\LOCALDB#A6F550C6\tsql\query
You will now be in the SQL server like it was a normal instance, you can copy your Northwind MDF file to the data directory of the instance (mine was the root of my user folder) and then in the databases node in the management studio right click and select attach, select the MDF file and then attach as normal.
Hope this helps.
How about just restoring via SSMS using Steps:
Download northwind (https://northwinddatabase.codeplex.com/) and save .bak somewhere
Open SSMS
Connect to (localdb)\ProjectsV12 (or whatever version you have)
Right Click Databases Node (see image)
Select Restore...
In Restore Database window, Source | choose 'Device' radio button and in drop down 'Backup media Type' choose File and then click 'Add' button browse to location of downloaded .bak file
That's it, your .bak should be loaded to a new database on your machine.

Error in Commandline Installation of SQL Server 2005 Express SP 3

I am facing a strange issue while installing SQL Server Express 2005 on Windows XP SP3 (German OS) machine.
PFB the description:
I am performing a silent installation of SQL Server 2005 via a .bat file.
The installation command is as following :
start /wait Setup.exe /qn INSTANCENAME=<instance name> ADDLOCAL=SQL_Engine SAPWD="strong password>" SECURITYMODE=SQL SQLACCOUNT="NT-AUTORITÄT\SYSTEM" DISABLENETWORKPROTOCOLS=0 TARGETDIR="C:\Program Files\Microsoft SQL Server \"
The SQLACCOUNT parameter is derived at run-time be checking the language of the OS. In English, it is "NT AUTHORITY\SYSTEM" .In German, it is "NT-AUTORITÄT\SYSTEM"
If I provide the above command directly to the command line, then installation is successful. But, if I put the same command in the bat file, then installation fails.
The reason for failure mentioned in the log files is that the system is not able to recognize the local system account.
In the log files, I checked that when the passed parameter is "NT-AUTORITÄT\SYSTEM" then, SQL logs contain the name of the parameter as "NT-AUTORIT-T\SYSTEM".
This parameter is invalid and hence, the installation is failing.
I also tried providing the ".\LocalSystem" as the parameter but, still installation fails.
Please Note:
I faced a similar issue while installing SQL Server 2008 Express on the same machine.
I changed the installation command from "NT-AUTORITÄT\SYSTEM" to "NT AUTHORITY\SYSTEM", then the issue was solved.
