APAR status

Closed as program error.

Error description

Here is an example.
SimpleEntity has two attributes id and strItem. And the
strItem
of id=001 is AAAbcdAefghAA.
"TRIM with LEADING" worked as expected. The following JPQL
returns "bcdAefghAA".
em.createQuery("SELECT TRIM(LEADING 'A' FROM e.strItem) FROM
SimpleEntity e where e.id = '001'")
"TRIM with TRAILING" also worked as expected. The following
JPQL returns "AAAbcdAefgh".
em.createQuery("SELECT TRIM(TRAILING 'A' FROM e.strItem)
FROM
SimpleEntity e where e.id = '001'")
But the following JPQL results in DatabaseException.
em.createQuery("SELECT TRIM('A' FROM e.strItem) FROM
SimpleEntity e where e.id = '001'");

Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server Liberty - Java Persistence APA - JPA *
*                  2.1 & EclipseLink                           *
****************************************************************
* PROBLEM DESCRIPTION: EclipseLink throws an exception when    *
*                      parsing a Query containing the TRIM()   *
*                      operation on DB2                        *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The following sample code demonstrates how an application would
encounter this exception:

Entity:
    @Entity
    @Table(name = "SIMPLE_TABLE")
    public class SimpleEntity {
        @Id @Column(name = "ID")
        private String id;
        @Column(name = "STR_ITEM")
        private String strItem;
    }

Test:
    Query query1 = em.createQuery("SELECT TRIM('a' FROM
e.strItem) FROM SimpleEntity e where e.id = '001'");
    query1.getResultList();//Exception

The last line of code, above, will result in this exception:

    Internal Exception: com.ibm.db2.jcc.am.vo: DB2 SQL Error:
SQLCODE=-418, SQLSTATE=42610, SQLERRMC=null, DRIVER=4.8.87
    Error Code: -418
    Call: SELECT TRIM(? FROM STR_ITEM) FROM SIMPLE_TABLE WHERE
(ID = ?)
        bind => [a, 001]
    Query: ReportQuery(referenceClass=EntityTblTrim sql="SELECT
TRIM(? FROM STR_ITEM) FROM SIMPLE_TABLE WHERE (ID = ?)")

Problem conclusion

The fix for this APAR changes the EclipseLink implementation and
involves an update to the thirdparty source. See

The fix for this APAR is currently targeted for inclusion in
Service Level (Fix Pack) 9.0.0.9 of WebSphere Application Server
version 9.0 and in fix pack 18.0.0.2 for WebSphere Application
Server Liberty. Please refer to the Recommended Updates page for
