Topic: Incorrect Tag:Multiple Attributes with Same Collection Type

Question

I have an Object Type that contains multiple attributes with the same collection type. When I use OracleXML getXML to generate xml, the tag for all elements created for any of the matching types is the tag for the 1st of the similar attributes.
work_t_v is an object view of a relational schema
SQL> desc work_t_v
Name Null? Type
WORK_ID NUMBER(38)
TITLE_OF_WORK VARCHAR2(512)
MESH_HEADINGS MESH_HEADINGS_T
AUTHORS AUTHORS_T
COMMENT_ON WORK_REFERENCES_T
COMMENT_IN WORK_REFERENCES_T
ERRATUM_IN WORK_REFERENCES_T
REPUBLISHED_FROM WORK_REFERENCES_T
REPUBLISHED_IN WORK_REFERENCES_T
SQL> desc work_references_t
work_references_t TABLE OF WORK_REFERENCE_T
Name Null? Type
REFSOURCE VARCHAR2(255)
NOTE VARCHAR2(255)select
work.work_id,
work.title_of_work,
work.comment_on comment_on,
work.comment_in comment_in,
work.erratum_in erratum_in,
work.republished_from republished_from,
work.republished_in republished_in
from work_t_v work
where work_id = 99350984
results in tag of <comment_on> for all the elements built from the work_references_t type (i.e., there are no <comment_in>, <erratum_in>, <republished_from> or <republished_in> elements)
sample result is:
<COMMENT_ON>
<COMMENT_ON_ITEM>
<REFSOURCE>J Infect Dis 1998 Aug;178(2):601 [CommentOn]</REFSOURCE>
</COMMENT_ON_ITEM>
</COMMENT_ON>
<COMMENT_ON>
<COMMENT_ON_ITEM>
<REFSOURCE>J Infect Dis 1998 Aug;178(2):601 [CommentIn]</REFSOURCE>
</COMMENT_ON_ITEM>
</COMMENT_ON>
<COMMENT_ON>
<COMMENT_ON_ITEM>
<REFSOURCE>J Infect Dis 1998 Aug;178(2):601 [ErratumIn]</REFSOURCE>
</COMMENT_ON_ITEM>
</COMMENT_ON>
<COMMENT_ON>
<COMMENT_ON_ITEM>
<REFSOURCE>J Infect Dis 1998 Aug;178(2):601 [RepublishedFrom]</REFSOURCE>
</COMMENT_ON_ITEM>
</COMMENT_ON>
<COMMENT_ON>
<COMMENT_ON_ITEM>
<REFSOURCE>J Infect Dis 1998 Aug;178(2):601 [RepublishedIn]</REFSOURCE>
</COMMENT_ON_ITEM>
</COMMENT_ON>
The above xml should be:
<COMMENT_ON>
<COMMENT_ON_ITEM>
<REFSOURCE>J Infect Dis 1998 Aug;178(2):601 [CommentOn]</REFSOURCE>
</COMMENT_ON_ITEM>
</COMMENT_ON>
<COMMENT_IN>
<COMMENT_IN_ITEM>
<REFSOURCE>J Infect Dis 1998 Aug;178(2):601 [CommentIn]</REFSOURCE>
</COMMENT_IN_ITEM>
</ERRATUM_IN>
<COMMENT_ON>
<ERRATUM_IN_ITEM>
<REFSOURCE>J Infect Dis 1998 Aug;178(2):601 [ErratumIn]</REFSOURCE>
</ERRATUM_IN_ITEM>
</ERRATUM_IN>
<REPUBLISHED_FROM>
<REPUBLISHED_FROM_ITEM>
<REFSOURCE>J Infect Dis 1998 Aug;178(2):601 [RepublishedFrom]</REFSOURCE>
</REPUBLISHED_FROM_ITEM>
</REPUBLISHED_FROM>
<REPUBLISHED_IN>
<REPUBLISHED_IN_ITEM>
<REFSOURCE>J Infect Dis 1998 Aug;178(2):601 [RepublishedIn]</REFSOURCE>
</REPUBLISHED_IN_ITEM>
</REPUBLISHED_IN>bracketed portion [] is contained within the refsource string to indicate what type of reference it should be displayed as.
I also found that if I use the -withDTD parameter to include the dtd, the dtd includes the appropriate elements (comment_in, erratum_in, republished_from and republished_in). However, it incorrectly defines refsource and note multiple times (once for each WORK_REFERENCES_T attribute).
Are these known problems? Will they be fixed? I'm more concerned about the XML problem than the DTD problem.

Answer 1

Using the version of XML SQL Utility that comes with the next XSQL Servlet release 0.9.8.6 I did the following:
create type foo as object (a number);
create type foolist as table of foo;
create view fooview
as select
cast(multiset(
select sal from emp where rownum < 2)
as foolist) list1,
cast(multiset(
select sal from emp where rownum < 2)
as foolist) list2
from dual;
When I request a "SELECT * FROM FOOVIEW"
through getXML I get:
<?xml version="1.0"?>
<ROWSET>
<ROW num="1">
<LIST1>
<LIST1_ITEM>
<A>800</A>
</LIST1_ITEM>
</LIST1>
<LIST2>
<LIST2_ITEM>
<A>800</A>
</LIST2_ITEM>
</LIST2>
</ROW>
</ROWSET>
So this appears fixed in the next code drop.
In the interim, I'll email you the new JAR file until (since it won't be on OTN for a few more days).
