Wanting to deploy my project on different servers I would prefer to be able to specify a connect string using a relative path. I can't seem to get that to work and want to know if there is some trick to it...?
You could build the absolute path in the app and pass that in the connection string.
So, if you know that the database file is in the database
subfolder of the application folder, you could do something like this (C#):
string relativePath = @"database\myfile.s3db";
string currentPath;
string absolutePath;
string connectionString;
currentPath = System.Reflection.Assembly.GetExecutingAssembly().Location;
absolutePath = System.IO.Path.Combine(currentPath,relativePath);
connectionString = string.Format("DataSource={0}", absolutePath);
SQLiteConnection cnn = new SQLiteConnection(connectionString);
(Someone can probably correct me on how to get the current path).
How about this?
"Data Source=|DataDirectory|mydb.db;..."
I believe |DataDirectory|
point to the directory where your app is located. I use NHibernate and it works with the following:
<add key="hibernate.connection.connection_string"
value="Data Source=|DataDirectory|mydb.db;Version=3;Compress=False;synchronous=OFF;" >
Like this:
String currentPath = System.IO.Path.GetDirectoryName( Application.ExecutablePath );
