Here's an untested, top-of-head Python Script that assumes you pass in a
variable called offset that defaults to 0.

----
records = context.your_zsql_method(args)
batch_size = 5

last_record = min([offset+batch_size,len(records)])

for record_num in range(offset, last_record):
    print records[record_num]['some_info']

for page in range(0,len(results),batch_size):
    print '<a href=your_url?offset=%s>%s</a>' % (page,page/batch_size)
return printed
-----

It's incomplete and ugly, but should get you well on your way.

HTH,
