Access sqlite from a remote server

Question

I am wondering how i can access an sqlite database that is sitting a remote server.I have read threads discouraging it but i need to do it if its possible.

Answer 1

SQLite is file-based only. There is no way to talk to it over TCP/IP.

Like an Access database file, you have to have the database file in a network shared folder. The path is usually going to be a UNC path, like "\server\sharename\folderpath\databasefile".

The problem is the connection string you built isn't a connection string. It's a partial string. You have this:

DataSource = @"\\\\" + txtipaddress.Text + @"\qscanDBAttacheds\test.s3db;Version=3;New=False;Compress=True;"

The "DataSource" part has to be part of the string you build. You don't have that. You need this:

string connString = @"Data Source=\\" + txtipaddress.Text + @"\qscanDBAttacheds\test.s3db;Version=3;New=False;Compress=True;"

Answer 2

While sqlite itself does not provide any network endpoints you can use a web gui such as sqlite-web.

Assuming you have python installed you can install it with

pip install sqlite-web

Once installed, start the web interface with:

sqlite_web my_database.db

By default it runs on http://127.0.0.1:8080/ ie is only accesible from the localhost.

To make it visible on your LAN/WAN start it with:

sqlite_web --host 0.0.0.0 my_database.db

While running with --host 0.0.0.0 is fine on your own home network, it's a really bad idea to do it on a public host (even though the app allows setting a password). For remote access on a public host it would be safer running it on 127.0.0.1 and then forward the port over ssh.

^{Disclaimer: I am not affiliated with the author of the app. Just had the same need as the op and found the app on github.}

Answer 3

You could use php on the server to run whatever sql commands you need and just navigate to the php page from the device.

Answer 4

SQLite isn't a network database, so it doesn't have any network connection ability built into it.

You would need to either:

• Make the SQLite DB available on a network-accessible shared drive OR
• Write/find an existing network server/web service for it

A web application is essentially a web service. If you happen to be running a web application on top of this DB, just expose certain levels of DB access to admins-only.

It's not recommended you do this because multiple threads/clients/etc. accessing a SQLite DB simultaneously may lead to concurrency problems very quickly.

Answer 5

Navicat can connect via SSH to a remote sqlite database.

For smaller project im using phpliteadmin

Answer 6

You cannot directly access an sqlite database remotely like that. If you need to share it, you will have to develop a web service and talk to the web service rather than the database from your Qt Application.

There are some tools which act as a web service for stuff like that, e.g. this site has some links.
