Hi,
Which driver should I use? Because when I do what you suggested, I get
"This method is not yet implemented" ... stmt.setFetchSize(1000).
I am using the official postgresql-8.1-404.jdbc3.jar driver.
Many thanks.
Khaldoun

Set autocommit to false, then use the method setFetchSize() of
the Statement to set the maximal rows that are read into the memory.
For example:
con.setAutoCommit(false);
stmt = con.createStatement();
stmt.setFetchSize(1000);
