Question

You create a calculated field that finds the average of a column of numbers. Access automatically names the field Expr1. Which of the following statements is true regarding the automatic naming of the calculated field?

A) You cannot edit an expression in a calculated field that has been named Expr1 by Access
B) Access assigns Expr1 to a calculated field name when an expression contains an error.
C) You cannot edit the name of a calculated field that has been named Expr1
D) Access assigns Expr1 to a calculated field without a name, and this name can be edited

Answer 1

Access automatically assigns the name Expr1 to unnamed calculated fields, and users have the ability to rename them to something more descriptive.

Step-by-step explanation:

The correct answer is D) Access assigns Expr1 to a calculated field without a name, and this name can be edited. When you create a calculated field in Access and do not specify a name for it, Access will automatically name it Expr1. This is a placeholder name that indicates it is an expression. However, you can and should rename this field to something more meaningful to help identify what the field represents or the calculation it performs. To rename the field, you simply click on the Expr1 text and type the new name, or you can right-click on the field, select 'Rename Field', and enter the desired name.
