Re: [eclipselink-dev] JPA query - NOT MEMBER OF exception

Looks like a bug.

As a workaround have you tried something like this?

SELECT a FROM Zinstance a WHERE NOT (?1 MEMBER OF a.groupUUIDs)

I have a very simple test case involving a single Java class, two database
tables, a basic collection mapping and JPA queries. The SQL for the DB schema is
shown below

CREATE TABLE Z_INSTANCES (

INSTANCE_UUID CHAR(36) NOT NULL

, NAME VARCHAR2(256)

, CONSTRAINT Z_INSTANCES_PK PRIMARY KEY (INSTANCE_UUID) using index tablespace
&INDEX_TABLESPACE ENABLE) tablespace &DATA_TABLESPACE;

CREATE TABLE Z_GROUPS(

INSTANCE_UUID CHAR(36) NOT NULL

, GROUP_UUID CHAR(36) NOT NULL

, CONSTRAINT GROUPS_UK1 U! ! ! NIQUE (INSTANCE_UUID,GROUP_UUID) using index
tablespace &INDEX_TABLESPACE ENABLE

, CONSTRAINT Z_INSTANCES_FK1 FOREIGN KEY (INSTANCE_UUID)

REFERENCES Z_INSTANCES(INSTANCE_UUID) ON DELETE CASCADE ENABLE) tablespace
&DATA_TABLESPACE;

The Java class is very simple

public class Zinstance {

private String uuid;

private String name;

private Set<String> groupUUIDs;

public Zinstance() {

this.uuid = UUID.randomUUID().toString();

this.groupUUIDs = new HashSet<String>();

}

}

The OR mapping is shown below:

<entity class="my.temp.Zinstance">

<table name="Z_INSTANCES" />

<attributes>

<id name="uuid">

<co! ! ! lumn name="INSTANCE_UUID" updatable="false" />

</id>

<basic name="name">

<column name="NAME" />

</basic>

<basic-collection name="groupUUIDs">

<value-column name="GROUP_UUID" />

<collection-table name="Z_GROUPS">

<primary-key-join-column>INSTANCE_UUID</primary-key-join-column>

</collection-table>

<private-owned />

<join-fetch>OUTER</join-fetch>

</basic-collection>

</attributes>

</entity>

I attempted the following JPA queries

SELECT a FROM Zinstance a <-Success

SELECT a FROM Zinstance a WHERE a.groupUUIDs = ?1 ! ;! ;! ; <-Success

SELECT a FROM Zinstance a WHERE ?1 LIKE a.groupUUIDs <-Success

SELECT a FROM Zinstance a WHERE ?1 NOT LIKE a.groupUUIDs <-Fail incorrect results

SELECT a FROM Zinstance a WHERE a.groupUUIDs IS EMPTY <-Success

SELECT a FROM Zinstance a WHERE a.groupUUIDs IS NOT EMPTY <-Success

SELECT a FROM Zinstance a WHERE ?1 MEMBER OF a.groupUUIDs <-Success

SELECT a FROM Zinstance a WHERE ?1 NOT MEMBER OF a.groupUUIDs <-Fail CCE

The ClassCastException for the “NOT MEMBER OF” should I file a bug or is it user
error? Is there an alternative syntax for this type of query?

FYI I am using EclipseLink 2.3.1.
