XMLSequence to XMLTable
Hi!
I need a help to use XMLTable instead of XMLSequence.
This is the part of my XML.
<emiDocAnt>
<owner>11111111111111</owner>
<idDocAnt>
<idDocAntPap>
<tpDoc>01</tpDoc>
</idDocAntPap>

<idDocAnt>
<idDocAntPap>
<tpDoc>05</tpDoc>
</idDocAntPap>
<idDocAntPap>
<tpDoc>06</tpDoc>
</idDocAntPap>
</idDocAnt>
</emiDocAnt>I have this statement that works fine, it retruns the data inside the idDocAntPap group and its owner.
SELECT EXTRACTVALUE(VALUE(vw),'/emiDocAnt/owner'),
EXTRACTVALUE(VALUE(vw3), '/idDocAntPap/tpDoc')
FROM tb_projCargaTMP,
TABLE(XMLSequence(EXTRACT(XMLAutorizacao,'/emiDocAnt'))) vw,
TABLE(XMLSequence(EXTRACT(vw.column_value,'//idDocAnt'))) vw2,
TABLE(XMLSequence(EXTRACT(vw2.column_value,'//idDocAntPap'))) vw3;But I'd like to use XMLTable instead of XMLSequence. The problem is: how can I get the "owner" value?
SELECT vw."owner",
vw."tpDoc"
FROM tb_projCargaTMP,
XMLTABLE('/emiDocAnt/idDocAnt/idDocAntPap'
PASSING tb_CargaTMP.XMLAutorizacao
COLUMNS "owner" NUMBER(14) PATH ???, <-- How can I get the owner value?
"tpDoc" NUMBER(2) PATH '/idDocAntPap/tpDoc',
"serie" VARCHAR2(3) PATH '/idDocAntPap/serie',
"subserie" VARCHAR2(2) PATH '/idDocAntPap/subser',
"nDoc" NUMBER(20) PATH '/idDocAntPap/nDoc',
"dEmi" DATE PATH '/idDocAntPap/dEmi'
) vw;Thanks!!!
Based off a similar question in {message:id=4093475}, you have two options, depending upon whether you want to use XQuery or not within XMLTable.

Converting XMLSEQUENCE to XMLTABLE
So we've gotten part-way into converting all of our code using XMLSEQUENCE to instead use XMLTABLE and everything compiles fine. However, we now realize (a bit late, I realize, and it is documented) that the PASSING clause with XMLTABLE requires a SQL expression.
All of the XML queries that we use involve the evaluation of a PL/SQL variable - for example, an XMLTYPE variable passed into a procedure. The first example below is using a SQL expression (the return from the XMLTYPE function) in the PASSING clause and this works, but the second example tries to refer to a PL/SQL variable which generates an exception.
Is XMLTABLE totally off the table if you are working with PL/SQL variables, same as if you attempt to refer to a package variable within a SQL statement?

Question on XMLTABLE related to XMLSEQUENCE
Hi Mark,
Easy one for you.
recently i tried XMLTABLE which i used as a replacement for TABLE(XMLSEQUENCE) which was used with versions lower than 10g R2.
here is the test.

SQL> Sofar good. Now i want to replace the TABLE(XMLSEQUENCE) with XMLTABLE operator. I got success with the usage of one XMLTABLE. But when i have requirement for 2, i.e collection within a collection i could not succeed.
here is the one i tried.
select
deptid, dname, empid, ename
from xml
,xmltable('/DeptList/Dept' passing xmltype(data)
columns
deptid number path '/Dept/@id'

,xmltable('/Dept/EMP' passing value(a)
columns
empid number path '/EMP/@id'
,ename varchar2(20) path '/EMP/name')

Concatenate elements with same name in sequence
version 9.2
I have a clob column containing xml - unregistered
Some of the old xml has multiple <notes> elements and the new xml has one <notes> element. I have made a view that successfully extracts the xml from the column and it works great, but when I have multiple <notes> elements the view fails since I am using extractvalue(). I need to select the <notes> tags concatenated into one column in sequence when I have multiples. I am guessing the sequence should be as they appear in the xml document from top to bottom since there is no sequence attribute. I know how to use xmlsequence and xmltable to get the individual <notes> tags but they are not concatenated. Is there a magic xmlsequence/concatenation function that will do what I want here?

</Accident>I am also trying to register this xml to improve performance. However, when I see things like this in the xml I wonder what will happen when I try to register this xml. The DTD, I have no XSD, currently only supports one <notes> tag. Do I have to clean up all the xml in column to match the current DTD before registering? I could also use a good, EASY, example of how to register a schema.
Thanks...You can use the string aggregation technique to concatenate the Notes element.

And is that enought to improve performance or is it rather style only change .
currently I've got plan like:
create table ARH_2 as
SELECT SSS_task_id, extractValue(value(taskhist),'/task/taskId') taskId,
extractValue(value(taskhist), '/task/id') id_,
extractValue(value(typeId), '/typeId') typeId,

XMLTable performance vs. TABLE(XMLSequence())
Hi everybody,
I've faced an issue that I hope I can find help with.
There's a task to parse a large (~15 MB) XML text and update a table based on it. So I've created a procedure that takes one XMLType parameter and does the job. Pretty straightforward. However, the thing is that, if I use XMLTable, which is the preferred method, to parse the XML, it runs for hours. Once I replace XMLTable with TABLE(XMLSequence()) method, the procedure completes in under two minutes on the same machine. Looks very strange to me.
Any ideas what could be causing such a poor performance of XMLTable?

As I said, Oracle' statement of Direction was that it would become "deprecated", the moment it officially is mentioned in the docs, you will see less and less effort in maintaining (in this case) the propriety methods...

Newbie- xmlsequence and GROUPING
Below works OK with 1 record. If a person has 2 records, I need it GROUP by DeptOrg
Drop table dummy;
Create table dummy (Pidm number(9,0)
,orgn varchar2(6)
,title varchar2(20)
,Lastname varchar2(20)
,Firstname varchar2(20));
Insert into dummy(pidm,orgn,title,lastname,Firstname)
values(649,'3601','Assoc. VP','Doe','Jane');
Insert into dummy(pidm,orgn,title,lastname,Firstname)
values(649,'3555','Finance Admin','Doe','Jane');
Insert into dummy(pidm,orgn,title,lastname,Firstname)
values(649,'3575','General Expense','Doe','Jane');
Select B.drecord
FROM(
select rpad(t.column_value.getrootelement(),20) || ': ' || t.column_value.extract('//text()') drecord
from table(xmlsequence(xmltype(cursor(select C.Orgn Deptorg,C.* from dummy C where C.pidm=649)).extract('ROWSET/ROW/*'))) t

Steve42Hi Steve,
Since you're on 10.2, you can start using XMLTable and XQuery.
Something like this :
SQL> SELECT x1.deptorg,
2 rpad(x2.col_name,20) || ': ' || x2.col_value as drecord
3 FROM XMLTable(
4 '/ROWSET/ROW'
5 passing dbms_xmlgen.getxmltype('select C.Orgn Deptorg,C.* from dummy C where C.pidm=649')
6 columns deptorg varchar2(30) path 'DEPTORG',
7 cols xmltype path '.'
8 ) x1,
9 XMLTable(
10 'for $i in /ROW/*
11 return element e
12 {
13 attribute name {local-name($i)},
14 $i/text()
15 }'
16 passing x1.cols
17 columns col_name varchar2(30) path '@name',
18 col_value varchar2(30) path '.'
19 ) x2
20 ;
DEPTORG DRECORD

Hi,
I have the follwing xml in column tmp_xml of table tmp_table:
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
<env:Header/>
<env:Body>
<ses:getCriteriaNamesListResponse xmlns:ses="http://session.kernel.cmp.com/">
<return>
<item>CRITERIA_UID</item>
<item>CRITERIA_LAST_NAME</item>
<item>CRITERIA_MEXI_ADDRESS</item>
<item>CRITERIA_FIRST_NAME</item>
<item>NONE</item>
<item>CRITERIA_NISS</item>
<item>CRITERIA_INAMI</item>
</return>
</ses:getCriteriaNamesListResponse>
</env:Body>
</env:Envelope>
I want to extract all sequences of "item"
This select return 1 empty row:
select extractvalue( value(b), '/env:Envelope/env:Body//return/item', 'xmlns:env="http://schemas.xmlsoap.org/soap/envelope/", xmlns:ses="http://session.kernel.mexi.com/"' ) item
tmp_table a, table(xmlsequence(extract(a.tmp_xml, '//return'))) b
The following select returns 7 empty rows:
select extractvalue( value(b), '/return/item') item
tmp_table a, table(xmlsequence(extract(a.tmp_xml, '/env:Envelope/env:Body//return/item', 'xmlns:env="http://schemas.xmlsoap.org/soap/envelope/", xmlns:ses="http://session.kernel.mexi.com/"'))) b
Could anyone give me a tip how to retrieve the values for "item"?
Regards, HansThank you! This works! Maybe just one more question:
Suppose the following XML:
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
<env:Header/>
<env:Body>
<ses:findAccountByCriteriaResponse xmlns:ses="http://session.kernel.cmp.com/">
<return>
<detailedInfo>Account(s) found: 9</detailedInfo>
<operationResult>MPROXY_RESULT_OK</operationResult>
<value>
<firstName>bernard</firstName>
<lastName>dupont</lastName>
</value>
<value>
<firstName>christophe</firstName>
<lastName>dupont</lastName>
</value>
<value>
<firstName>nele</firstName>
<lastName>dupont</lastName>
</value>
<value>
<firstName>philippe</firstName>
<lastName>dupont</lastName>
</value>
<value>
<firstName>pierre</firstName>
<lastName>dupont</lastName>
</value>
<value>
<firstName>kamiel</firstName>
<lastName>dupont</lastName>
</value>
<value>
<firstName>johan</firstName>
<lastName>dupont</lastName>
</value>
</return>
</ses:findAccountByCriteriaResponse>
</env:Body>
</env:Envelope>
The following sql, again, returns empty rows:
alter session set cursor_sharing=exact
select x.*
tmp_medimail_accounts t
xmltable(
xmlnamespaces('http://schemas.xmlsoap.org/soap/envelope/' as "env", 'http://session.kernel.cmp.com/' as "ses")
, 'env:Envelope/env:Body/ses:findAccountByCriteriaResponse/return/value'
passing t.tmp_xml
columns firstName varchar2(30) path '/firstName',
lastname varchar2(30) path '/lastName' ) x ;
Thank you for the replies! Hans -

48 rows selected.Now, I was wondering if you can have just one implementation of XMLTable in the query which will reduce the complexity of this. Both the queries looked like they gave me the same results.
Thank you,
Rahul.It's quite hard to tune a query without seeing the table structure and available indices as well as relationship between each other but I'll try.
In your sql which you've given the table alias AD, you have this filter criteria
AND FIELD_NAME IN (
SELECT FIELD_NAME
FROM APPLICATION_FIELDS
WHERE FIELD_TYPE IN ('Checkbox','Radio','Select','SelectM', 'RadioHoriz','RadioPara')
) </br>
My question is, is FIELD_NAME a column in the APPLICATION_DATA table? If it is, try moving this clause outside of the current sub-query it is in, i.e. one more level up. It looks like you put them inside the wrong level.
I would also try converting this <COL> IN <SUB-QUERY> to a join, if that wouldn't affect the no. of rows returned. I can't tell for sure since I dont know the relationship between your tables.
It looks to me like you're doing this
SELECT <col list>
FROM ( SELECT -- LEVEL 1
FROM APPLICATION_DATA AD
WHERE AD.APPLICAITON_ID IN ( -- LEVEL 2
SELECT
FROM APPLICATIONS A
WHERE A.JOB_ID IN (
<SUBQUERY>
AND A.ACCOUNT_ID IN (
<SUBQUERY>
AND FIELDNAME IN ( -- SHOULD BE INSIDE LEVEL1
<SUBQUERY>
) AD,
( SELECT ....
) FD
WHERE .... -
Retrieving query information from a SYS_REFCURSOR using XMLSEQUENCE
G'day.
I am trying to retrieve the colum name from the first column selected in a query. I have no idea what the column name is, however I was pointed in the direction of the following code snippet to help me retrieve the name:
DECLARE
v_rc_sv SYS_REFCURSOR;
v_query VARCHAR2(4000);
v_value_col_name VARCHAR2(4000) := NULL;
v_updated_query VARCHAR2(4000);
BEGIN
v_query := 'SELECT val FROM a_table';
OPEN v_rc_sv FOR v_query;
FOR gen_cursor IN (
SELECT ROWNUM rn,
t2.COLUMN_VALUE.getRootElement () NAME,
EXTRACTVALUE (t2.COLUMN_VALUE, 'node()') VALUE
FROM TABLE (XMLSEQUENCE (v_rc_sv)) t,
TABLE (XMLSEQUENCE (EXTRACT (COLUMN_VALUE, '/ROW/node()'))) t2)
LOOP
IF v_value_col_name IS NULL THEN
v_value_col_name := gen_cursor.NAME;
EXIT;
END IF;
END LOOP;
CLOSE v_rc_sv;
-- Now we have the column name, we can construct a query string which
-- wraps the original query with a standard select statement that includes the column
-- name.
v_updated_query := 'SELECT ' || v_value_col_name || ' FROM (' || v_query || ')';
EXCEPTION
WHEN OTHERS THEN
RAISE;
END;From the last line, you can see I use the name of the column to wrap the query string, so that eventually I can use the updated query to retrieve the value from the query.
My question is, can I also use the same method (by using XMLSEQUENCE) to tell me how many columns have been selected in the unknown string ? Also can it tell me if the unknown query has put an alias on any of the select columns (and what they might be) or the query is using the original column name ? ie: select name from person_table VS select name the_name from person_table (where the_name is the column alias) ?

Updated with the formatting tag, thanks for the tipHi,
If you're using 11g, you can take a look at UTL_XML.PARSEQUERY.
Here's an example with your requirement, it'll output the number of colums and their names (and aliases) :
DECLARE
tmplob clob;
parsed_qry xmltype;
num_of_cols number;
BEGIN
dbms_lob.createtemporary(tmplob, true);
utl_xml.parsequery(
user,
q'{SELECT employee_id as emp_id, last_name FROM hr.employees WHERE job_id = 'IT_PROG'}',
tmplob
--dbms_output.put_line(tmplob);
parsed_qry := xmltype(tmplob);
select count(*) into num_of_cols from xmltable('//SELECT_LIST_ITEM' passing parsed_qry);
dbms_output.put_line ('Number of column(s) : ' || to_char(num_of_cols));
for r in (
select *
from xmltable('//SELECT_LIST_ITEM'
passing parsed_qry
columns colnum for ordinality,
colname varchar2(30) path 'COLUMN_REF/COLUMN',
colalias varchar2(30) path 'COLUMN_ALIAS' default '<no alias>')
loop
dbms_output.put_line('Column '||to_char(r.colnum) || ' : ' || r.colname ||', alias = '||r.colalias);
end loop;
dbms_lob.freetemporary (tmplob);
END;

Could someone explain what extractvalue, xmlsequence and extract is doing in the following query:
select
extractvalue(value(a),'Notebook/@Brand') As Brand
,extractvalue(value(a),'Notebook/@Model') As Model
from prod_xml_tab b,
table( xmlsequence( extract( demo_field,'Product/Notebook' ) ) ) a
where demo_field is not null;I went through documentation and still don't get it, and need some basic explanation step by step. for example, what is actually EXTRACT returning for first and second row?
the code for table and data is as follows:
create table prod_xml_tab (demo_field xmltype);
insert into prod_xml_tab values('

thank you... this is a bit confusing when trying to reproduce excellent example on wrong version.
anyway, do you know what is this (+) doing formally? is this a notation similar to left outer join? I noticed it in some other example which I cannot find now.It is an outer join.

Help with a simple XMLTable query
Newbie Oracle XML developer here and need a little guidance on how to retrieve multiple records in an xmltype table using xmltable.
My document in the xmltype table looks like this:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<echoems:ECHOMetrics xmlns:echoems="http://myURL/myFilename.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://myURL/myFilename.xsd
http://myURL/myFilename.xsd">
<OrderMetrics>
<OrderItemMetric>
<requestor>user1</requestor>
<product>123</product>
</OrderItemMetric>
<OrderItemMetric>
<requestor>0.0.0.0</requestor>
<product>ABC</product>
</OrderItemMetric>
<OrderItemMetric>
<requestor>user3</requestor>
<product>XYZ</product>
</OrderItemMetric>
</OrderMetrics>
</echoems:ECHOMetrics>
I want to get all the products:
Product
123
ABC
XYZ
I know to use XMLTable but am not sure how exactly to write it. If just one record, the following worked fine:
select extractvalue
(object_value,
'echoems:ECHOMetrics/OrderMetrics/OrderItemMetric/product',
'xmlns:echoems="http://myURL/myFilename.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"'
) object_value
from echoXML;
But with multiple records, I'm trying XMLTable but can't get it right. Trying something like this:
select m.product
from echoXML3
xmlTable(
(object_value,'echoems:ECHOMetrics/OrderMetrics/OrderItemMetric/*','xmlns:echoems="http://myURL/myFilename.xsd')
passing object_value
COLUMNS
product varchar2(85) path 'product') m;
Thanks in advance for any help on this.One more question. Instead of putting the xml doc in the query, how do I reference it from the xmlType table?
You have:
select *
from xmltable
'//OrderMetrics/OrderItemMetric'
passing xmltype(
'<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<echoems:ECHOMetrics xmlns:echoems="http://myURL/myFilename.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://myURL/myFilename.xsd">
<OrderMetrics>
<OrderItemMetric>
<requestor>user1</requestor>
<product>123</product>
</OrderItemMetric>
<OrderItemMetric>
<requestor>0.0.0.0</requestor>
<product>ABC</product>
</OrderItemMetric>
<OrderItemMetric>
<requestor>user3</requestor>
<product>XYZ</product>
</OrderItemMetric>
</OrderMetrics>
</echoems:ECHOMetrics>')
columns
prod varchar2(20) path 'product',
requestor varchar(50) path 'requestor'
However, the xmlDocument is already in an xmlType table called echoXML3 based on the xsd. I'm just trying to query it to get a relational result set. How, in the query above, do I replace the hardcoded xmlDoc with the xmlDoc located in my xmlType table?
I thought maybe something like this but it's not working:
select *
from xmltable
'//OrderMetrics/OrderItemMetric'
passing xmltype(select value(e)
from echoXML3,
TABLE(xmlsequence(extract(object_value,'echoems:ECHOMetrics/OrderMetrics/OrderItemMetric/*','xmlns:echoems="http://myURL/myFilename.xsd'))) e)
columns
prod varchar2(20) path 'product',
requestor varchar(50) path 'requestor'

Ora-03113 error with XMLTABLE inside subquery or view
I'm getting ORA-03113 error if I use a result of XMLTABLE inside a subquery of another query (whether XMLTABLE is inline, or from a view). Code below to reproduce this - vastly simplified and now rather meaningless - but produces same error. Has anyone saw this error re. XMLTABLE or know of metalink bugs on this ? I couldn't find anything. I'm having to use deprecated table(xmlsequence) instead, which doesn't get this error.

10g XMLTABLE - can I return XMLTYPE col as well as extract specific columns
Hi,
(This is for version 10.2.0.4)
Currently, we have a giant XML column which contains many parts to it. We split those into individual parts via XMLSEQUENCE and then loop through to extract information from two other XMLTYLE columns. I'd like to be able to use XMLTABLE to join the XMLTYPE columns to each other in one SQL statement, as I think it should be more efficient. (We're having issues when the big XML column has 400 or more parts in it - looping and doing extract values on two xmltype columns 400+ times is proving slow going!)
Anyway, what I'd like to do is use XMLTABLE to produce a table-like structure for each column, then join them so that 1st part in col1 = 1st part in col2 = 1st part in col3.
I've looked around at the documentation and google, but I'm getting stuck at one particular point - I would like to return both the XMLTYPE and specific extracted values from that XMLTYPE as part of the XMLTABLE on each column. I just can't seem to find a way to do it.
Here's an example (that I've nabbed from http://thinktibits.blogspot.com/2011/03/oracle-xmltable-example-part-1.html ) that will hopefully explain more clearly what I'd like to do, taking just one column to start with:
CREATE TABLE xml_test
(NOTEBOOK XMLTYPE);
insert into xml_test values ('<?xml version="1.0" encoding="UTF-8"?><Product Type=''Laptop''><Notebook Brand="HP" Model="Pavilion dv6-3132TX Notebook"><Harddisk>640 GB</Harddisk><Processor>Intel Core i7</Processor><RAM>4 GB</RAM></Notebook><Notebook Brand="HP" Model="HP Pavilion dv6-3032TX Notebook"><Harddisk>640 GB</Harddisk><Processor>Intel Core i7</Processor><RAM>6 GB</RAM></Notebook><Notebook Brand="Toshiba" Model="Satellite A660/07R 3D Notebook"><Harddisk>640 GB</Harddisk><Processor>Intel Core i7</Processor><RAM>4 GB</RAM></Notebook><Notebook Brand="Toshiba" Model="Satellite A660/15J Notebook"><Harddisk>640 GB</Harddisk><Processor>Intel Core i5</Processor><RAM>6 GB</RAM></Notebook></Product>');

4 Toshiba Satellite A660/15J Notebook 640 GB Intel Core i5 6 GB
4 rows selected.What I'd like is to have the COLUMN_VALUE contents from the first select to appear as a column in the second select - is it possible?
At worst case, I could do a join, only that produces a cartesian product because I don't know how to label the rows from within the first query's XMLTABLE (if I used rownum in the query itself, does that guarentee to come out in the same order as the XMLTABLE results? Would part 1 always be labeled row 1, part 2 row2, etc?).
I hope that makes some sort of sense - I'm not up on XML terms, sadly.
ETA: If there's no way of doing this via XMLTABLE, is there any other way of achieving it?

I'm not sure I understand the rest of your requirement.
Do you want to further break the generated XMLType into a set of relational rows, or repeat the operation on different columns from the same base table?
