LocalDB connections

[thorstenkampe]

Will go-sqlcmd support LocalDB connections on Windows? (Basically the equivalent to sqlcmd -S (localdb)\MSSQLLocalDB -E.)

On Windows I get the following error with the latest go-sqlcmd 1.4.0: "no named pipe instance matching 'MSSQLLOCALDB' returned from host '(localdb)'".

It would be great to fix this. Is it something we need to fix in the underlying go-mssqldb driver?

I don't know if it needs to be in the driver. I think there's some logic needed to calculate the right pipe name to connect to.
We'd probably only support automatic instances that are started externally.
The documentation shows how you may be able to connect using go-sqlcmd today by doing the pipe name calculation yourself.

eg np:\\.\pipe\LOCALDB#F365A78E\tsql\query

I get "Access Denied" when using the correct np (obtained from SqlLocalDB.exe) with go-sqlcmd. It works fine with the ODBC version.

I had to uninstall the sqlcmd go version and use sqlcmd ODBC version =(

That's the solution (not good) that I found.

I'm having the same issue. When is this being pulled from backlog and fixed?

I'm having the same issue. any updates?

With 1.8.2 I am able to use the pipe name directly.

It's a poor substitute but worth a try until we have time to address it.
