You can probably manage to export simple tables in a generic manner using only the functions provided by
QSqlDatabase(via thetables()andrecordsfunctions as a starting point), but as far as I know, you’ll need to use database-specific queries to get complete schema information.This is best done, in my opinion, with your specific database implementation’s tools. For instance, SQLite has a
.dumpcommand that does just that. MySQL has a dedicatedmysqldumputility. PostgreSQL haspg_dump, etc…It’s safer to use pre-built tools for your specific engine. Getting all the DDL statements correct, plugging in the keys and triggers at the right time, worrying about encoding, … is quite a task.
