LIMIT also allows you to specify a starting record, i.e.
eg. say a table is created using:
create table fred (f1 char(10), f2 int)
Then it has neither keys nor an AUTO_INCREMENT field.
Let's say 1000,000 records are then inserted into table fred.
I then say 'select * from fred' and loop through results writing to a web page.

You'll need to do an order by on both columns (so you'll need to index both
columns in a compound index), then use the LIMIT keyword which is designed
for exactly this job.
Alternatively, unload the data using mysqldump, then edit the table
definition to have an autoincrement column, then
