Comparing data in one column to another column

[rynorem]

I have two separate columns in my query but they contain the same kind of data. These two columns data should match but some of the data doesn't. Can I write a criteria that will show me only the rows that do not match.

DUTY POSC
11B1 11B1
11B1 11B1
11C1 11B1
11B1 11B1
92Y1 11B1
11B1 11B1
13F1 21B1
For example, I want the query to show me only the rows in which the data in the Duty column doesn't match the POSC column.

In the POSC field's criteria type:

<>[DUTY]

Or the other way round...
