I was asked to repost this question, due to the answers were not going the right directions.
I have a detached database similar to to Northwind.MDF I want to import a .CVS file into this MDF file. I have the mdf file as part of my Solution Explorer in vs2010 and I can look work with the data, just no way to import. In vs2010 I can use the Server Explorer and connect with no problems. the connection string looks like this:
Data Source=.\SQLEXPRESS;AttachDbFilename=D:\ASPX\sdb1\customer.mdf;Integrated Security=True;User Instance=True
When I try to use any tool outside of vs2010 I cannot connect. Non of the sqlserver tools connect and give me an access denied, even when I try to attach the file from within Management Studio.
Attach database failed for Server 'STEPHANS-PC\SQLEXPRESS'. (Microsoft.SqlServer.Smo)
ADDITIONAL INFORMATION:
An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)
This should not be this tuff to import data from a CSV.
You have to connect to your user instance database using an special connection string. An user instance database is a sql express database based upon an mdf file (just what you have).
This link explains how to connect from SSMS to your User Instance Database:
