Bind a named placehouder that appears more than one time

Bind a named placehouder that appears more than one time.

In some queries (more extensive than the example) that can be helpfull.

Example:

QSqlQuery qry;

qry.prepare("SELECT :param, :param;");
qry.bindValue(":param", 1);
qry.exec();

It's better than...

QSqlQuery qry;

qry.prepare("SELECT :param1, :param2;");
qry.bindValue(":param1", 1);
qry.bindValue(":param2", 1);
qry.exec();
