Problem summary
**************************************************************** * USERS AFFECTED: * * All DB2 11 for z/OS users of an SQL * * statement containing a view or SQL table * * function with an XMLELEMENT and * * XMLNAMESPACES function. * **************************************************************** * PROBLEM DESCRIPTION: * * ABEND0C4 at DSNXGXTT OFFSET078E or * * ABEND0C4 at DSNXOV1 OFFSETB25C could * * happen for an SQL statement satisfying * * all of the following conditions: * * 1. It references a view or SQL table * * function. * * 2. The view or SQL table function * * contains more than one CTE. * * 3. These CTE reference more than one * * XMLELEMENT function. * * 4. Some of XMLELEMENT in the CTE don't * * have XMLNAMESPACES function. * **************************************************************** * RECOMMENDATION: * **************************************************************** An example is shown below: CREATE TABLE T1 ( C1 XML, C2 DECIMAL(18,0)); CREATE FUNCTION TUDF1() RETURNS TABLE(CAMT054 XML) LANGUAGE SQL NOT DETERMINISTIC NO EXTERNAL ACTION READS SQL DATA RETURN with CTE1 as( select xmlelement(name "cte1", xmlattributes(T1.C2 as "Num"), xmlelement(name "test1",'test') ) NTRYDTLS from T1 ), "DOCUMENT" as( select XMLELEMENT(name "Document", XMLNAMESAPCES(default 'http://posample.org'), (select C1 from CTE1) ) DOC from T1 ) select DOC from "DOCUMENT" ; SELECT * FROM TABLE(TUDF1( )); Because the XMLELEMENT in CTE1 doesn't have XMLNAMESPACE, DB2 did not correctly process the aforementioned SQL statement and resulted in ABEND0C4 RC38 at DSNXGXTT OFFSET078E or ABEND0C4 at DSNXOV1 OFFSETB25C.
Problem conclusion
DB2 has been modified to correctly process the aforementioned SQL statement. Additional Keywords: SQLXML SQLVIEW SQLCTE SQLTABLEEXPR SQLTUDF SQLTABLEUDF
