In Neo4j, you can use the datetime
function to convert a string representation of a date and time to a datetime
value. The datetime
function takes a string in the ISO-8601 format (e.g., “2020-01-01T12:00:00Z”) and returns a datetime
value that can be stored in a Neo4j property.
Here is an example of how to use the datetime
function to convert a string to a datetime
value in a Neo4j query:
// Convert a string to a datetime value
WITH '2020-01-01T12:00:00Z' AS input
RETURN datetime(input) AS output
This query converts the string “2020-01-01T12:00:00Z” to a datetime
value and returns the result as the output
column. The resulting datetime
value can then be used in other queries or stored in a Neo4j property.
You can also use the toString
function to convert a datetime
value to a string representation. For example:
// Convert a datetime value to a string
WITH datetime('2020-01-01T12:00:00Z') AS input
RETURN toString(input) AS output
This query converts the datetime
value “2020-01-01T12:00:00Z” to a string and returns the result as the output
column.
Keep in mind that the datetime
and toString
functions are only available in Neo4j versions 3.5 and later. If you are using an earlier version of Neo4j, you can use the timestamp
function to convert a string to a timestamp
value, or the to_timestamp
function to convert a timestamp
value to a string.
