Description
When using an output variable for a stored procedure which is not set (isNull returns true), then the NULL flag is not reset when the call returns.
QVariant CMyClass::GetValue(QVariant::Type T)
{
QSqlQuery Query;
Query.setForwardOnly(); //Necessary for a stored procdure
Query.prepare("{call stored_procedure(?)}");
QVariant V(T);
Query.addBindValue(V,QSql::Out);
Query.exec();
return Query.boundValue(0);
}
This code always returns a NULL Qvariant.
