Why would that be slow? Using LIKE isn't always a bad thing. In this
case, the LIKE condition begins with a constant rather than a
wildcard, so it should perform well. It can even benefit from an index
on `somefield` if one exists.
I only see a couple issues with tedd's query:
1) As written, it only returns one row. To get it to return a list,
you'd have to call it repeatedly inside a for...loop where $offset
increments begins at some value and increments/decrements to an ending
value. But then he did say "from memory -- use with caution". The
general idea is correct.
2) It implements numeric pagination, which is usually based on a
fixed number of rows per page. The OP wanted alphabetical pagination
(like an address book) with each page containing all entries that
begin with the selected letter.
