Query in Query

Zarkon

I have a select query

@QSqlQuery q;
QString queryString;

queryString.sprintf("select Application_ID from Applications where Application_name = '%s' and Application_major = %d and Application_minor=%d", application_info.Application_name.toLocal8Bit().data(), application_info.Application_major, application_info.Application_minor);

if (!q.prepare(queryString)) {
qDebug() << "Database error prepare";
qDebug() << q.lastError();
return;
}
if (!q.exec()) {
qDebug() << "Database error exec";
qDebug() << q.lastError();
return;
}@

Now I want to do an update query that makes use of this select query. Is there a way to make use of 'q'? Like

QSqlQuery upd;

UPDATE "whatever fields" where application_id is in "query above"

? Offline

The Query language depends of you database.
you can do :
UPDATE "whartever fields" where application_id in (select...)

I think the best way to do it, if you already have the query result is :
UPDATE "whartever fields" where application_id in (id1, id2...)
