Hi
For our purpose we want to free Items during query execution.
So my idea would be:
1) instantiate item with malloc:
Item* tmp_item = (Item*)malloc(sizeof(Item));
2) invoke copy constructor
List_iterator_fast<Item> it(*join->fields);
item1=it++;
tmp_item->Item(*item1);
now the question:
- how would the copy constructor Item(& item) look like - especially
for join->result->send_data(...)....
- Is it a good idea?
Does a similiar method already exist?
Thanks for any comments in advance.
