Please note that this procedure is deprecated.

Use the following ones instead, which allow for better support in a cluster:

deprecated procedure new procedure

apoc.uuid.install('<name>', $config)

apoc.uuid.setup('<name>', '<query>', '<dbName>', $config)

apoc.uuid.remove('<name>')

apoc.uuid.drop('<name>', '<dbName>')

apoc.uuid.removeAll()

apoc.uuid.removeAll('<dbName>')

where <dbName> is the database where we want to execute the automatic UUIDs and has "neo4j" as default value.

See here for more info.

This procedure is not intended to be used in a cluster environment, and may act unpredictably.

Enable automatic UUIDs

This procedure is part of a set of procedures that handle automatic adding of UUID properties, via the UUID Handler Lifecycle. The UUID handler is a transaction event handler that automatically adds the UUID property to a provided label and for the provided property name.

By default automatic adding of UUIDs is disabled. We can enable it by setting the following property in apoc.conf:

apoc.conf
apoc.uuid.enabled=true

Usage Examples

We can remove all UUID handler (installed by apoc.uuid.install), by running the following query:

CALL apoc.uuid.removeAll();
Table 1. Results
label installed properties

"Person"

FALSE

{uuidProperty: "myUUID"}

If we try to remove UUID handlers when non are installed, the output will indicate that no handlers were removed:

CALL apoc.uuid.removeAll();
Table 2. Results
label installed properties
