How to run both Mysql and SQlite at the same time in Qt?
Saving records should go simultaneously in both Mysql and SQlite.

Answer 1

It is necessary to create an object with different names, they are set in the second parameter.
For example like this:

QSqlDatabase::addDatabase("QMYSQL", "ClassName1")
QSqlDatabase::addDatabase("QSQLITE", "ClassName2")

If you add two connections with the same name, the second one replaces the first one.
After the database is closed, you can use names to remove connections.

QSqlDatabase::removeDatabase("ClassName1");
QSqlDatabase::removeDatabase("ClassName2");
