What is DROP INDEX ON using Cypher in Neo4j?

• You can drop an index using the DROP INDEX ON statement. This will remove the index from the database.
• So, to drop our previously created index, we can use the following statement:

DROP INDEX ON :Album(Name)

• When the statement succeeds,the following message is displayed:

Relative Tags : neo , neo4j , graph database , neo4j cypher , neo4j python , neo4j tutorial , neo4j download , neograft

View the Schema:

• You can now use the  :schema command to verify that the applicable index has been removed from the schema.
• Simply type this:

:schema

• You will see that the index is no longer in the schema:

NOTE:-

• The colon(:) operator is used to refer a Node or a Relationship label name.
• The above syntax describes that it drops an existing index created on < property_name> of <label_name> of a Node or a Relationship.
