[Interest] QSqlQuery

Hi.
I have some questions about database support in Qt 5.
First of all, is it safe to transfer a QSqlQuery instance from one
thread to another to process him in another thread. I.e. I want to
execute SELECT query on "DB" thread and return a QSqlQuery from that
thread to the GUI thread, where I will navigate and show users the
result of the query.
And the second question, I've found the following warning in the
documentation:
"For some databases, if an active query that is aSELECTstatement exists
when you callcommit()
<qthelp://org.qt-project.qtsql.520/qtsql/qsqldatabase.html#commit>orrollback()
<qthelp://org.qt-project.qtsql.520/qtsql/qsqldatabase.html#rollback>,
the commit or rollback will fail. SeeisActive
<qthelp://org.qt-project.qtsql.520/qtsql/qsqlquery.html#isActive>() for
details."
Does the SQLite driver has that pain?
Thanks.
