Bastien pretty much answered your question because the example you provided
was, in theory, correct. Besides, unless you're messing with a production
system, you could always just try out simple stuff like this on your own and
see what happens. More fun that way anyhow.

I would like to increment the current value of a field X without having to retrieve field X beforehand. Can I do this?

Example:

UPDATE my_table set field_1 = (current_field_value -1) WHERE...blah, blah, blah....
