[Qt-interest] qtsql simultaneous queries to db

[Jason H]

This really depends on your driver. 

I know SQLITE won't allow it - you have to connect to a different db file, all connections to a single db file will be forced to one.

Subject: [Qt-interest] qtsql simultaneous queries to db

Hi,

I need to run another query, during fetching result from QSqlQuery, something 
like this:

q=QSqlQuery;
q.exec("select somethig from table");
while(q.next()) {
    // need run another query to calculate some values
    //....
}

Is it possible with one connection to db? For example to create another 
QSqlQuery object and call q1.exec() and so one, during reading from previous 
QSqlQuery? 
Or do I need separate connections to run simultaneously queries?

I have qt4.5 and postgresql 8.1

Greetings
Marek
