Having a QSqlDatabase as a class member and avoid the connection still in use warning

[qlands]

Hi,

I have a class that has a QSqlDatabase as a private member.

private:
    QSqlDatabase m_database;

private:
    QSqlDatabase m_database;

To copy to clipboard, switch view to plain text mode 

I use m_database in several functions of the class like:

QSqlQuery *query = new QSqlQuery(m_database);
 
..
 
delete query;

QSqlQuery *query = new QSqlQuery(m_database);

..

delete query;

To copy to clipboard, switch view to plain text mode 

However in the destructor of the class I remove the connection with

m_database.close();
QSqlDatabase::removeDatabase("MyConnection");

m_database.close();
QSqlDatabase::removeDatabase("MyConnection");

To copy to clipboard, switch view to plain text mode 

But I always get the warning "MyConnection' is still in use, all queries will cease to work."

How can I avoid the warning?
