Comparing two fields to find differences

I have a database in which a handful records in field A don’t match the info in field B. So for example:

Field A Field B
05-03-3-C 05-03-3-C
09-01-5-B 09-01-5-B
15-05-1-C 05-01-5-D

Is there an easy way to select the records in which the data differs in A and B?

Select A≠B
