**Strings** A string literal is enclosed in single quotes—for example: 'literal'. A string literal that includes a single quote is represented by two single quotes—for example: 'literal''s'. FROM User WHERE User.name = 'Vincent' **Integers** Integer literals support the use of PHP integer literal syntax. FROM User WHERE User.id = 4 **Floats** Float literals support the use of PHP float literal syntax. FROM Account WHERE Account.amount = 432.123 **Booleans** The boolean literals are true and false. FROM User WHERE User.admin = true FROM Session WHERE Session.is_authed = false **Enums** The enumerated values work in the same way as string literals. FROM User WHERE User.type = 'admin' Predefined reserved literals are case insensitive, although its a good standard to write them in uppercase.
