Literals

Executable query literals include integers, floating-point numbers, booleans, strings, bytes and null. UNKNOWN is represented as a nullable boolean.

RETURN 1_000 AS count, 0xFF AS hex, 0o755 AS octal,
       0b1010 AS binary, .5 AS fraction, 1. AS decimal;

Integer literals use Int64 and approximate values use Float64 in query execution. M, F and D suffixes are parsed, but an M literal is not an exact-decimal runtime value: decimal literals are currently represented as f64.

Character strings support backslash escapes, newline-separated chunks and no-escape literal forms. Use single quotes for strings in examples to avoid ambiguity with delimited names.

RETURN 'hello '
'world' AS greeting, 'line\nnext' AS escaped, X'0A ff 10' AS bytes;

Byte literals contain hexadecimal pairs; whitespace is allowed between pairs. Newline-separated chunks are also accepted.

Typed DATE/TIME/DATETIME/DURATION and INTERVAL literals are syntax only. A type recognized by the parser is not necessarily representable in a query result.

No-escape strings

Prefix a single-quoted string with @ to keep backslashes literally:

RETURN @'C:\data\graph' AS location, X'CA'
'FE' AS chunked_bytes;

Without @, sequences such as \n are decoded as escapes. Byte-string chunks contain hex digits, not character-string bytes.
