Unable to fetch large resultset

Question

I got this error when i was trying to retreive records from a sql server table which cosists of around 2 lakhs of records
com.microsoft.sqlserver.jdbc.SQLServerException: The system is out of memory. Use server side cursors for large result sets:Java heap space. Result set size:78,585,571. JVM total memory size:66,650,112.
how can i fetch the above said records

3 choices:
1) make your java heap size big enough to hold the entire ResultSet. If you're using Sun's Java (almost everyone does), then you increase the maximum heap with the -Xmx parameter whent the JVM is started. It looks like you're using the default maximum, which is pretty small. See:
http://java.sun.com/j2se/1.3/docs/tooldocs/solaris/java.html
2) retrieve the ResultSet from the database incrementally, and process it incrementally. Statement.setFetchSize() suggests to the driver how much of the ResultSet to keep in memory (and to retrieve in one chunk from the database), but it's common for scrollable ResultSets to ignore this hint and try to keep everything in memory. A ForwardOnly ResultSet (the default) is more likely to work incrementally, but it depends totally on your driver.
3) break the data into multiple queries....
