Using select

Looking with phpmyadmin, I have about 60 rows in a table called 'photos'. One of the fields is titled "product", which holds a photograph id like 'RWS1981035W00025-01F'. The product field is defined as varchar(25), as the length will vary from about 19 chars to 23.

When I run this query:

SELECT * FROM photos WHERE product = 'RWS1981035W00025-01F'

it returns no results, even though I can see it with my own eye, even if I copy bloody product id directly from a SELECT * FROM photos result set. Incredibly frustrating. What am I missing here? Thanks much in advance for any and all help.
