Can you retrieve QSqlQuery.LastError after QSqlQuery.Finish?

Quick question since documentation is not very clear about this:

When freeing up recourses by calling QSqlQuery Finish, does it clear the QSqlQuery lastError? I know it will keep bound values according to the Class Reference, but I can't find or test yet if it keeps the QSqlQuery lasterror?
Thx in advance.

You could spend five minutes writing a quick test or reading the Qt source code to see that it does. Alternatively, you could just assume that it does not and cache lastError() before you do.

Code:

---

void QSqlQuery::finish()
{
    if (isActive()) {
        d->sqlResult->setLastError(QSqlError());
...

---

The docs are quite clear that you probably do not need to be calling finish() anyway.

I did read the source, and the I did read about not needing to call finish UNLESS you want to free up resources. I do currently cache the lastError() before calling finish, but in my search for chipping away extra extra extra safety code I needed to be absolutely sure. And although the source is very obvious about it... I'd better ask than having to apologize later. And due DB maintenance I currently don't have access to the DB-es so I couldn't test it myself.

Thx.
