Currently I am using `statement.executeQuery(qStr)` in java to select a large amount of data from mysql. Unfortunatly, java keeps running out of memory at the `statement.executeQuery(qStr)` statement with exception `java.lang.OutOfMemoryError: Java heap space`. I am wondering if there is a method to stream load data from mysql. So that I can handle the selected data trunk by trunk to avoid running out of memory? 

Note that: I am using eclipse and this [post](http://dev.eclipse.org/mhonarc/lists/eclipse-dev/msg02841.html) shows me how to increase the heap memory for java to use inside eclipse. But after I followed it's method, i am still running into the same problem.

Thanks in advance.
