I am trying to run the ItemTest of CaveatEmptor in the following setting:
MySQL 4.0.22
driver 3.0.16.ga

But I got an java.sql.SQLException: Syntax error

And the exception occurs in this line of ItemDAO:

public Bid getMaxBid(Long itemId) {
   maxBidAmount = (Bid) q.uniqueResult();


Can someone please tell me

Don't use MySQL or use a different version that supports this SQL query. Also, apply the debugging techniques in "How to ask for help" before posting.
