? (question mark)

Type

Wild Card (Single Character) Symbol

Purpose

The ? wild card character is used to substitute for exactly one unspecified character in an alphanumeric string. It can, however, be used repeatedly in a field to specify the exact number of characters that have been omitted. The symbol can be used in any logical comparison or record selection context.

Example 1
