Quizplus · Accepted Answer

The expression [LastName] &"," [FirstName] is an example of concatenation, which combines the two separate fields (last name and first name) and adds a comma separator in between. Concatenation is a common technique used to combine text values in a query or report. The other options, IsNull and nonnull, are not relevant to this expression, and an expression using a logical operator would require comparisons or conditions.
