i am working on Spring Data Neo4j and use Cypher-Language for some Queries. Works fine so long, but delete a Node don't work.
For Example:
@Query("start u=node(5) delete u")
void deleteNode();
i use the dependencies
<dependency>
<groupId>org.neo4j</groupId>
<artifactId>neo4j-cypher</artifactId>
<version>1.6.2</version>
</dependency>
<dependency>
<groupId>org.neo4j</groupId>
<artifactId>neo4j-kernel</artifactId>
<version>1.6.2</version>
</dependency>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-neo4j</artifactId>
<version>2.0.1.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-neo4j-rest</artifactId>
<version>2.0.1.RELEASE</version>
</dependency>
i cannot use version 1.7.2 of Cypher because it conflict with spring data neo4j and the kernel 1.6.
Can anybody help me?
i don't want to delete a Node with
repository.delete(5);
Because i also want to delete Relationships and any more.
Thx!
I think you should delete the relationship with the node you want to delete. @Query("start u=node(5) delete u")
If you want to delete a node ,you should confirm the node haven't relationship with other node. Please have a try with following codes: @Query("start u=node(5) match u-[r]-() delete u,r")
Interesting idea, didn't try that yet b/c SDN still officially points to Neo4j 1.7 but that will change soon.
Why can't you update to SDN 2.1.RC2 ?
SDN 2.0.1 doesn't work with Neo4j 1.8 as there were API changes in Neo4j.
You will need to add @Transactional
to the method as well.
