What is the best way to only do an update if it going to update only one

row?
I want to protect my code so that it won't accidentally update more than

one row.
I can do a select first but there must be an easier way. :-)

Do the update with conditions (this is a SQL question)

UPDATE `tblFOO` SET `bar` = 'a_value' WHERE `barID` = '227098762' 

will only update the record(s) where barID is  227098762
