数据库更新语句：
String sql = "update flower set name=? and descr=? and breed=? and price=? and lowerPrice=? and fileName=? and uses=? and person=? and festival=? and isIndex=? where id=?";
try {
conn = ConnectionManager.getConnection();
pstmt = conn.prepareStatement(sql);
pstmt.setString(1, "'"+flower.getName()+"'");
pstmt.setString(2, "'"+flower.getDescr()+"'");
pstmt.setString(3, "'"+flower.getBreed()+"'");
pstmt.setDouble(4, flower.getPrice());
pstmt.setDouble(5, flower.getLowerPrice());
pstmt.setString(6,"'"+ flower.getFileName());
pstmt.setString(7, "'"+flower.getUses()+"'");
pstmt.setString(8, "'"+flower.getPerson()+"'");
pstmt.setString(9, "'"+flower.getFestival()+"'");
pstmt.setInt(10, flower.getIsIndex());
pstmt.setInt(11, id);
pstmt.executeUpdate();
