[Qt-interest] QSqlQuery and placeholders of the same name

[Anthony Serdyukov]

Good day.

Just a simple code.

-------------------------------------
QSqlQuery query;
query.prepare("select * from some_table where columnA = :param AND
columnB = :param");
query.bindValue(":param", someValue);
query.exec();
-------------------------------------

But it doesn't work. The placeholders of the same name are not bound correctly.
First occurrence of :param placeholder gets value of NULL, and the
second occurrence gets proper value.

I have found a task about it.

The task is rejected without any explanation.

Could somebody explain this behavior?
