    DECODE_JSON(expression)

    Unmarshals the JSON-encoded string into a N1QL value. The empty string is MISSING.

    ENCODE_JSON(expression)

    Marshals the N1QL value into a JSON-encoded string. MISSING becomes the empty string.

    ENCODED_SIZE(expression)

    • Array: The number of elements in the array.

    • Object: The number of name/value pairs in the object
