    @SGaist Hello! I'm building a second app using QMySQL database, the first app (the one about this topic) works perfectly as expected, but the second tells me that the driver isn't loaded. QSqlDatabase: MYSQL driver not loaded QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7 I added mysql dll dir in PATH environment variable, but same problem stay the same.. Have you an idea please? EDIT: nevermind, I'm just stupid, I forgot the "Q" before "MYSQL" call in code line: QSqlDatabase db = QSqlDatabase::addDatabase("MYSQL"); Now it's: QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL"); and strangely, works better.. Again, thank you all for your help!
