how to access localDB from Windows Service

Question

I need to use data base locally. I have created database in (LocalDB)\\v11.0 Server with Visual Studio 2012. Everything is ok when connecting from e.g. console application.

Answer 1

So i found out solution myself, how to connect instance of (localdb) from Windows Service which runs as Local System:

I used this articles: http://technet.microsoft.com/pl-pl/library/hh212961.aspx http://dba.fyicenter.com/faq/sql_server_2/Verifying_a_Login_Name_with_SQLCMD_Tool.html http://social.technet.microsoft.com/wiki/contents/articles/4609.troubleshoot-sql-server-2012-express-localdb.aspx

So i shared my localdb (as in 1st article) the problem was I couldn't connect with sqlcmd named pipe np://. I found anwer in 3rd article:

When using sqlcmd, ensure that you are using the SQL Server 2012 version (found in %Program Files%\Microsoft SQL Server\110\Tools\Binn). If you have previous versions of sqlcmd installed, calling sqlcmd alone from the command line will most likely use the old version (which isn't localdb-aware) since the older path appears first in your PATH environment variable. It may be a good idea, in general, to manually adjust your PATH environment variable so that the 110 versions are picked up first.

This small information in fact was crucial;)

so i created user: user with password: pass321!@.

In my windows service my Sql connectionString looks:

"Data Source=(localdb)\\.\\MyInstanceShared;Integrated Security=false;User Id=user;Password=pass321!@"

Integrated security set to false value is also important.

Maybe it will help somebody.
