Re: How to mimic a subfile with java? - an easy option...

["Bruce Jin" <brucej@xxxxxxxxxxxxxxxxxxxx>]

 We use OPTIMIZE FOR in sql. In my application I display, say, 5 records at
a time so I use OPTIMIZE FOR 5 ROWS. I had a file with 1,500,000 records.
The response time is the same as that of a tiny file.  Now we have to
implement Previous and Next buttons. The following link shows this type of
coding implemented with servlet.
