Re-installation questions with LocalDB

This machine has been used with several different settings before. At least at some time it works with db connection on SQL Express 2014 in the network.

Steps taken:
1)Uninstalled SambaPOS5
2)Deleted SambaSettings.txt
3)DL 5.612
4)Re-installed with 2014 LocalDB options

Questions:
1)What’s the default db instance name? Is it “SambaPOS5”, is sn “sa” and is pwd “sambapos” Please check the pic below, did I put in the right string?

1a)If so, some how I cannot connect to it using MS Management Studio then what would be the possible cause?

The instance would be (LocalDb)\v11.0

LocalDB is not a service. It is a program that runs along with SambaPOS when you close SambaPOS it closes as well.

Still no go!

Anyone see a problem in my login of the db?
the password I typed is “sambapos”
I have tried it with both SambaPOS5 running and not running.
Also tried Windows authentication

This is the error screen if you can guess out what it say.
There is at least an error code

You are using SQL Server Profiler??? Not SSMS

You should provide English error details not ask us to guess

switch to SSMS but still no go. bad day.

Windows auth with user that started sbapos. SambaPOS has to be running at same time. Remember it’s not a service so if sambapos is not running then you have no instance to connect too.

And I can’t read a lick of that error.

quick google found this

maybe you have newer version than v11.0
Mine is (localDB)\MSSQLLocalDB

Yes that is the correct one for SQL LocalDB 2014

It is also aparently identical for SQL LocalDB 2016 but I am not sure what happens if you have both 2014 and 2016 installed - they can’t share the same default instance name.

Thanks of everyone, the instance in my case is

(LocalDB)\MSSQLLocalDB

case sensitive.
