I was under the impression that LIMIT was mySQL specific (although its
quite likely that their use of the keyword and the ubiqitous nature of mySQL
that other vendors have also adopted it.
anyway, many other DBs do implement an alternative in the form of FIRST, SKIP
keywords which effectively does the same as the LIMIT clause. (AFAICR
FIRST/SKIP is part of the SQL std)
