Query problem

[JavaSoft]

I have a problem with query. I wanna move lots data from, could be hundred records from a table in a database A to a table in database B when a user click a button. But i got error Out Of Memory. This is because i select all records from database A at once and then move it to database B. Anyone has good way for this case without using stored procedure ? only depends to Select command in java class. I am using MSSql as the database here == thx, a Java Addicted
