Detailed Description

RAII wrapper around QSqlDatabase::addDatabase / removeDatabase.

Creates a uniquely-named connection on construction, removes it on destruction. Avoids the common pitfall of reusing connection names or forgetting to call removeDatabase.

QGCSqlHelper::ScopedConnection::ScopedConnection ( const QString &  dbPath, bool  readOnly = false, const QString &  prefix = QStringLiteral("QGCSql")  )

explicit

Opens a connection to dbPath using the QSQLITE driver. prefix is prepended to the auto-generated connection name; useful for distinguishing concurrent connections in logs / Qt's connection registry. If readOnly is true, QSQLITE_OPEN_READONLY is set.
