Problem summary
**************************************************************** * USERS AFFECTED: All DB2 10 for z/OS users of CREATE VIEW * * that references built-in function XMLTABLE * * and have PE UI37474 (APAR PI22614) installed * **************************************************************** * PROBLEM DESCRIPTION: After PE PTF UI37474 (APAR PI22614) is * * installed, CREATE VIEW may receive * * ABEND S322 if the view definition meets * * the following conditions: * * * * 1. does not reference any base tables * * or views * * * * 2. reference the built-in function * * XMLTABLE and this XMLTABLE is the * * first table in the definition * **************************************************************** * RECOMMENDATION: * **************************************************************** After PE PTF UI37474 (APAR PI22614) is installed, CREATE VIEW may receive ABEND S322 if the view definition meets the following conditions: 1. does not reference any base tables or views 2. reference the built-in function (BIF) XMLTABLE and this XMLTABLE is the first table in the definition The view creation that meets the above conditions may not execute to completion, and the job may loop and hang. The following illustrates such a view: CREATE VIEW V1 AS SELECT T.* FROM XMLTABLE('$x/a/b' PASSING XMLPARSE(DOCUMENT '<a><b>9<c>1</c></b><b>8<c>1</c><d>2</d></b></a>' ) AS "x" COLUMNS C1 VARCHAR(3) PATH 'name(.)', C2 VARCHAR(3) PATH 'text()' DEFAULT '0') AS T; PTF UI37474 (APAR PI22614) contained several corrections that addressed the un-initialized pointers. One of the corrections caused the loop and hang in the create view that is described above. Prior to PTF UI37474, the view owner row in SYSIBM.SYSTABAUTH had an invalid string in the SCREATOR column and XMLTABLE in the STNAME column. With PTF UI37474, the insertion to SYSIBM.SYSTABAUTH for the view owner caused the loop and resulted in ABEND S322.
Problem conclusion
DB2 has been modified to create the view successfully, where the view definition meets the following conditions: 1. does not reference any base tables or views 2. reference the built-in function (BIF) XMLTABLE and this XMLTABLE is the first table in the definition With the PI64711 fix, the view owner row in SYSIBM.SYSTABAUTH has SYSIBM in the SCREATOR column and XMLTABLE in the STNAME column. According to the SQL Reference, the schema for XMLTABLE is SYSIBM but the function name cannot be specified as a qualified name. This rule remains unchanged.
