Qt Sqlite error 1 - table already exists - c++

Question

I have a problem with Qt and sqlite. Until recently, I didn't have any problems creating tables, but now, whenever I try to create a table (using the exact same function) I get an error message:
QSqlError("1", "Unable to fetch row", "table selections already exists")
My query strings are as follows:
CREATE TABLE external_files (path VARCHAR (255) NOT NULL, used INTEGER (12) NOT NULL);
This is the same as before too.
The strange thing is though, all the tables are created without a problem, but I still get error messages.
If you have any ideas why this happens, I would appreciate it. :)
UPDATE: Minimal, complete, verifiable example:
#include <QCoreApplication>
#include <QSqlDatabase>
#include <QSqlQuery>
#include <QSqlError>
#include <QFile>
#include <QTextStream>
#include <QDebug>
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE", "CONN");
db.setDatabaseName("test.db");
if(!db.open()){
qDebug() << "Connection failed!";
}
QFile tableListFile(":/resources/sql/tables.sql");
if(tableListFile.open(QIODevice::ReadOnly))
{
QTextStream stream(&tableListFile);
while(!stream.atEnd())
{
QString queryString = stream.readLine();
qDebug() << "Query string: " << queryString;
QSqlQuery query(queryString, db);
if(!query.exec()){
qDebug() << "Query error: " << query.lastError();
}
}
}
db.close();
return a.exec();
}
Thanks in advance.

Ok, I managed to solve the problem.
The query was executed 2 times for each query string, and that caused the error messages.
To get to the solution, i edited my code like this:
QString queryString = stream.readLine();
qDebug() << "Query string: " << queryString;
QSqlQuery query;
if(!query.exec(queryString)){
qDebug() << "Query error: " << query.lastError();
}
