hexadecimal defined as 0xX+

true or false, case-insensitive, not enclosed in quotation marks

A numeric constant can consist of integers 0-9 and a minus sign prefix. A numeric constant can also be float. A float can be a series of one or more decimal digits, followed by a period (.) and one or more decimal digits. There is no optional + sign. The forms .42 and 42 are unacceptable. You can use leading or trailing zeros before and after decimal points. For example, 0.42 and 42.0. A float constant, expressed in E notation, consists of the characters in this regular expression:

NaN and Infinity are floats.

Names of tables, columns, types, and other objects are identifiers. Because keyspace and table names are used in system file names, they must start with a letter or number and can only contain alphanumeric characters and underscores. All other identifiers, such as column and user-defined function names can contain any character. To specify an identifier that contains a special character, enclose the name in quotes.

An optional minus sign (-) followed by one or more digits.

Characters enclosed in single quotation marks. To use a single quotation mark itself in a string literal, escape it using a single quotation mark. For example, use '' to make dog possessive: dog''s.

32 hex digits, 0-9 or a-f, which are case-insensitive, separated by dashes (-) after the 8th, 12th, 16th, and 20th digits. For example: 01234567-0123-0123-0123-0123456789ab

Uses the time in 100 nanosecond intervals since 00:00:00.00 UTC (60 bits), a clock sequence number for prevention of duplicates (14 bits), plus the IEEE 801 MAC address (48 bits) to generate a unique identifier. For example: d2177dd0-eaa2-11de-a572-001b779c76e3

Separates terms and is used inside string literals, but otherwise CQL ignores whitespace.
