Connecting qt client application to a database on server

I am making a small project where there is a qt client application and basic server application written in c++. I am able to connect between two different computers through my application (over SSL, Socket). Now I want to connect my client application to access a sqlite database which is on server.

For example. lets say my client application is a simple login form. When user press Login button then I want my application to access the sqlite database on server, and verify whether the details are valid.

Above a just a example fr explanation. I know I can do the above thing in various other ways but I want the above functionality for something different.I searched a lot over internet but unable to find a good example or explanation. Please through some insight.
