Identifier

An identifier is a word or a few words that uniquely describe an object. Identifiers are often used instead of a database id due to their readability and portability.

Syntax

Identifiers are composed of lowercase alphanumeric characters and hyphens.

abcdefghijklmnopqrstuvwxyz1234567890-

• The first and last characters in an identifier must be a letter or a digit (not a hyphen).

Examples

gen
1sa
