Mysql c++ connector using all system memory - c++

Question

This code looks like using all the system memory. Why does it happend?
sql::Statement *Query;
sql::ResulSet *Result;
while(1){
Query = con->createStatement();
Result = Query->executeQuery("SELECT `Some` FROM `Table` LIMIT 1");
Result->next();
Result->close();
Query->close();
cout << "console message..." << endl;
//delete Query; SEGFAULT
}
If i comment all the lines except the cout the memory doesn't get filled. But using the SQL looks like Query = con->createStatement; is not replacing the old Query value and Result = bla; is not replacing the old value

Answer 1

createStatement() and executeQuery are creating new objects (which are the ones you store in Query and Result. Unless you explicitly delete them, they will remain in memory.
Add
delete Result;
delete Query;
To your loop.
BTW, this is in the connector documentation (together with sample code).

Answer 2

Well it looks like there is no info on google. I found what was the problem.
as SJuan76 said each call to createStatement and to executeQuery is a new object
So i started to do a lot of tryes and i figure out of the following
Use createStatement just once
Before deleting Result check if it's open and close
Delete Respuesta
Only delete con and Query at the end of the program auto_ptr(is your friend sometimes)
So the code to get the "forever running" program to use always the same memory shoud look like this
sql::Statement *Query;
sql::ResulSet *Result;
Query = con->createStatement();
while(1){
if(!Result->isClosed()) Result->close();
delete Result;
Result = Query->executeQuery("SELECT `Some` FROM `Table` LIMIT 1");
Result->next();
cout << "console message..." << endl;
}
