Simple update failure

[Richard Kurtz]

I am trying to update a mysql table.

UPDATE `rkurtz` SET `pic_desc`='Denver Botanic Gardens' WHERE `pic_num' >= '5268' && `pic_num` <= '5581'

When I run it I get:

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'pic_num` <= '5581'' at line 1

It's been awhile since I've done anything with MySQL so I've forgotten most of what I used to know (it seems).

I also tried

WHERE `pic_num' >= '5268' & `pic_num` <= '5581'
WHERE `pic_num' >= '5268' AND `pic_num` <= '5581'

with the sanme results.

All I'm trying to do is update the pic_desc field if the pic_num filed is between 5268 and 5581.
