Cannot run SQL in release mode, but I can in debug mode..

Baturtoraman

I am using Visual Studio 19. In release mode, the program gives warning like this:

QSqlDatabase: QPSQL driver not loaded
QSqlDatabase: available drivers:
Could not open connection!
"Driver not loaded Driver not loaded"

However it works pretty well in debug mode. How can I solve this problem?

Start by setting environment variable QT_DEBUG_PLUGINS=1 and then running your program. See if that gives you more information about why it seemingly cannot find the driver in Release build though it can in Debug build.
