2.3. Property values

This section describes how both nodes and relationships can have properties.

Properties are named values where the name is a string. Property values can be either a primitive or an array of one primitive type. For example String, int and int[] values are valid for properties.

NULL is not a valid property value. Setting a property to NULL is equivalent to deleting the property.

Table 2.2. Property value types
Type	Description
`boolean`
`byte`	8-bit integer
`short`	16-bit integer
`int`	32-bit integer
`long`	64-bit integer
`float`	32-bit IEEE 754 floating-point number
`double`	64-bit IEEE 754 floating-point number
`char`	16-bit unsigned integers representing Unicode characters
`String`	sequence of Unicode characters
`org.neo4j.graphdb.spatial.Point`	A 2D or 3D point object in a given coordinate system.
`java.time.LocalDate`	An instant capturing the date, but not the time, nor the timezone.
`java.time.OffsetTime`	An instant capturing the time of day, and the timezone offset, but not the date.
`java.time.LocalTime`	An instant capturing the time of day, but not the date, nor the timezone.
`java.time.ZonedDateTime`	An instant capturing the date, the time, and the timezone.
`java.time.LocalDateTime`	An instant capturing the date and the time, but not the timezone.
`java.time.temporal.TemporalAmount`	A temporal amount. This captures the difference in time between two instants.

For further details on float/double values, see Java Language Specification.

Note that there are two cases where more than one Java type is mapped to a single Cypher type. When this happens, type information is lost. If these objects are returned from procedures, the original types cannot be recreated:

A Cypher Duration is created when either a java.time.Duration or a java.time.Period is provided. If a Duration is returned, only the common interface java.time.temporal.TemporalAmount will remain.
A Cypher DateTime is created when a java.time.OffsetDateTime is provided. If a DateTime is returned, it will be converted into a java.time.ZonedDateTime.

Strings that contain special characters can have inconsistent or non-deterministic ordering in Neo4j. For details, see Cypher Manual → Sorting of special characters.
