SQL xml query problems

Hello,
I am trying to query a database column containing xml. How my problem is when I display my query on the page the data is not being shown properly.
The data in the database is like this:
<P><tag1>2003/05/22 11:01:34</tag1><tag2>2003/05/22</tag2><tag3>11:01:34</tag3><tag4></tag4>.......
However all that is returned is on the jsp page
2003/05/22 11:01:34<tag2>2003/05/22<tag3>11:01:34..............
i.e closing tags missing and empty pairs not shown at all.
My query is a simple
String sqlQuery="select * from table;
rs = stmt.executeQuery (sqlQuery);
rs.next();
out.print(rs.getString(1));
Can anyone suggest why the data stored in the column is being truncated and how I can prevent this.
Many thanks in advance
Les,

Surely this is because the browser is interpretting the tags as HTML tags? Do a "view source" on the page and it should be right.
Otherwise, you will have to store the query in the DB with escapt characters before the <'s

How to tune the performance of Oracle SQL/XML query?

Hi all,
I am running Oracle 9i and like to run the following Oracle SQL/XML query. It takes about 3+ hour and still not finish. If I get rid all the XML stuffs it only take minutes to run. Does anybody know how to what's the reason of this slow and how to tune it?
SELECT XMLElement("CUSTOMER",

Because this is not an equivalent of the original query.
drop table t1 cascade constraints purge;

create table t1 as select rownum t1_id from dual connect by level <= 5;

Sql select query problem

hi friends,
i've a view called "risk_efforts" with fields user_id,user_name,wknd_dt,week_day,prod_efforts,unprod_efforts.
Name Type
ROW_ID NUMBER
USER_ID VARCHAR2(14)
USER_NAME VARCHAR2(50)
WKND_DT VARCHAR2(8)
WEEK_DAY VARCHAR2(250)
PROD_EFFORTS NUMBER
UNPROD_EFFORTS NUMBER
data is like this:
when there is some data in prod_efforts, unprod_efforts will be null
when there is some data in unprod_efforts, prod_efforts will be null
for example:
USER_ID     USER_NAME     WKND_DT     WEEK_DAY     PROD_EFFORTS     UNPROD_EFFORTS
G666999     GTest     20100403     TUE     null 3
G666999     GTest     20100403     TUE     14     null
now i want to combine these 2 rows into 1 row i.e o/p should be like this
USER_ID     USER_NAME     WKND_DT     WEEK_DAY     PROD_EFFORTS     UNPROD_EFFORTS
G666999     GTest     20100403     TUE     14 3
i've tried all combinations but couldn't get the query. Please help me with the exact SQL select query.
thanks,
Girish

Welcome to the forum.
First read this:
Urgency in online postings
Secondly, it's always helpful to provide the following:
1. Oracle version (SELECT * FROM V$VERSION)
2. Sample data in the form of CREATE / INSERT statements.
3. Expected output
4. Explanation of expected output (A.K.A. "business logic")
5. Use \ tags for #2 and #3. See FAQ (Link on top right side) for details.
You have provided #3 and #4. However with no usable form of sample data forum members will often not respond as quickly as they could if you provided #2.
I'm just wagering a guess here but what about this:SELECT ROW_ID
, USER_ID
, WKND_DT
, WEEK_DAY
, MAX(PROD_EFFORTS) AS PROD_EFFORTS
, MAX(UNPROD_EFFORTS) AS UNPROD_EFFORTS
FROM RISK_EFFORTS
GROUP BY ROW_ID
, USER_ID
, WKND_DT
, WEEK_DAY

PL/SQL XML Parser (problem getting text of a node)

I am trying to get the contents of an ELEMENT (node with a CDATA section) using xmldom.getNodeValue(). However, it seems that there is a MAXIMUM number of characters that I can get back.
I think I've found a work-around using xmldom.writeToBuffer() which seems to write all of the CDATA contents to a VARCHAR2 variable. Now my problem is that it is using strings like '&#60' and '&#38'. I recognize these strings as being "internal representations of '<' and '&' respectively. I'd not have to replace every occurence of these types of strings with the ASCII equivalent -especially since I don't know all of the possible '&#nn' strings that may crop up.
Help!

The use of "//" or "\\" appears to be a bug in JServer. It has
been filed. You should not specify the path as a shared
directory as a workaround.

SQL date query problem with century/ year

We have an oracle database with about 6 million records. There is a date field called Entered Date that ranges from 1985 to the present.
The majority of these records were entered prior to Jan 1 2000.
If I run a query like
select count(*) from (tablename) where entered_date < '01-JAN-00' I get 0
if I do
select count(*) from (tablename) where entered_date < '31-DEC-99' I get 0
BUT IF I DO
select count(*) from (tablename) where entered_date < '01-JAN-00' I get 6 million records
or
select count(*) from TREASURY.ctrc where entrydate > '31-DEC-99' I get 6 million records
I've tried the same queries using 4 digit years but get the same results; it thinks that 2000 is the less than 1999
How do I get around this?
thanks

Hi,
975204 wrote:
there are 6 million records on the table
about two thirds have a date prior to Jan 1 , 2000How do you know that? From knowledge of the application, you may know that two thirds of them are supposed to have dates prior to 2000, but if
SELECT COUNT (*)
FROM      TABLE_NAME
WHERE      ENTRYDATE < TO_DATE ( '01-JAN-2000'
                       , 'DD-MON-YYYY'
;returns 0, that's pretty strong proof that none of them actually do.
When I look at the dates , they display as 31-DEC-86Another example of why using 2-digit years is such a bad idea.
I cant actually provide dump of this clients confidential dataSeriously; you can't provide one DUMP output? You've already said that it displays as 31-DEC-86, so even if the fact that 1 entry in the 6-million row table was done on December 31, 1986 was such a big secret, it's already out, and you won't be causing any more harm by showing the DUMP results.
I ran the query with the same format as the date ie
SELECT COUNT(*) FROM TREASURY.CTRC WHERE ENTRYDATE < TO_DATE ( '31-DEC-99'
, 'DD-MON-YY'
but same results
if the column is defined as a DATE type, does Oracle make a distinction based on how the data displays, meaning does it think that 31-DEC-86 is different than 31-DEC-1986?No, all DATE columns have the same format. A DATE may be displayed one way of the other, but it is stored as neither.
Do I need to convert all the data to a 4 digit year? You should always display dates with a 4-digit year.
Run an update query that says if year >= 80 and <= 99 add 19 in front of the year, else add 20 in front of the yearLet's find out exactly what the problem is, first.
Did you see Ascheffer's message? ^1^ It was dated just a couple of minutes before your last message, so you might not have noticed it. Run it to see what the actual 4-digit years are.
If it shows, for example, that there are a lot of entrydates in the years 2080 to 2099, and you decide that all of those really should be 100 years earlier, then use ADD_MONTHS to correct them:
UPDATE     table_name
SET     entrydate = ADD_MONTHS ( entrydate
                           , -100 * 12
WHERE   entrydate >= TO_DATE ( '01-JAN-2080'
                         , 'DD-MON-YYYY'
AND     entrydate < TO_DATE ( '01-JAN-2100'
                         , 'DD-MON-YYYY'

XML query problem

hello
i have xml DATA AS UNDER , i want TO GET alll THE DATA BETWEEN <eob> </eob> tags.
CREATE TABLE XMLTABLE (ID NUMBER, xml_data XMLTYPE);
INSERT INTO XMLTABLE
VALUES (1,
XMLTYPE
(' <eob>
<eobHeader>THE FOLLOWING STATEMENT should be included IN your STATEMENT OF Benefits OR appear WITH your CHECK endorsement:</eobHeader>
<eobText>Paid IN accordance WITH rate agreement.</eobText>
<eobFooter>FOR this discount TO APPLYthis claim.</eobFooter>
</eob>' ) );
it shoud display me AS UNDER. plase HELP me
THE FOLLOWING STATEMENT should be included IN your STATEMENT OF Benefits OR appear WITH your CHECK endorsement:
Paid IN accordance WITH rate agreement
FOR this discount TO APPLYthis claim.
i trid this but does NOT WORK
SELECT EXTRACTVALUE (xml_data, '/eob/eobHeader')
FROM XMLTABLE
thank you in advance

Your SQL statement asked only for the contents of the eobHeader node. The other two pieces of information are in sibling nodes so they are ignored by your SQL statement as you saw.
Doing the following gets each piece of information as a column
SELECT EXTRACTVALUE (xml_data, '/eob/eobHeader') hdr,
       EXTRACTVALUE (xml_data, '/eob/eobText') Txt,
       EXTRACTVALUE (xml_data, '/eob/eobFooter') Ftr
FROM XMLTABLEThe following is one option to make that into one string if you are really wanting the SQL to do the formatting
SELECT EXTRACTVALUE (xml_data, '/eob/eobHeader') || chr(10) ||
       EXTRACTVALUE (xml_data, '/eob/eobText') || chr(10) ||
       EXTRACTVALUE (xml_data, '/eob/eobFooter')
FROM XMLTABLE

How do I create an undeclared namespace node with sql/xml?

I have to interact with a .NET web service that is expecting to have an xml node with an undeclared namespace, i.e. <address xmlns=""> I figured that I could create this by using XMLATTRIBUTES ( '' AS "xmlns") but a null attribute will not be added to the attribute listing. This works fine for other xmlns entries that contain values. Without this undeclared namespace node, the web service reports an Internal SOAP failure message, so I have to include it. Do I have to resort to manually injecting this null attribute via DOM after I produce the xml? I'm using SQL/XML query generate the xml as a view which gives me the entire packet for this document/literal web service OTHER THAN this missing undeclared namespace element.
Any tips/suggestions would be helpful! Thanks a bunch, and have a Happy Holiday Season.
Eric

You can use UTL_RAW package.
First, convert string to raw with UTL_RAW.CAST_TO_RAW, then using UTL_RAW.CONVERT to convert raw to utf-8 and finally UTL_RAW.CAST_TO_VARCHAR to get utf-8 string.

Problem in xml query

Hi
I am working on BLS and having problem in xml query.I want to perform some calculation over xml columns.Than total of this as a new column.I can do this part in logic editor itself but can i do these both task by XSLT.
Can be made our own XSLT for this ?
I am feeling kind of fear to xslt. Can anybody help me in this.
Thanks a lot in advance
thomas

Ram,
In xMII there is a list of predefined xslt transforms that do something similar to what you are explaining. The 3 that I think may be what you are looking for are
they are under Calculation Transformations and Subtotal Transformation take a look at these and tell me if they are doing what you want to accomplish. In the xMII help file do a search on Inline Transforms or navigate to Advanced Topics -> Inline Transforms -> Predefined Inline Transforms. In this section there are examples of how to use these transforms and apply them in the query templates. If this is not what you are looking for can you explain in a little more detail along with a simple example of how you want this transform to work. Also why do you want to use xslt if you can already accomplish this in BLS?
Regards,
Erik

XML query structure problem

Hi experts,
I am looking for help on the following XML query. I have a table (example) organized as such:
meas     data_element
ABC     rate
DEF     rate1
DEF     rate2
DEF     rate3
GHI     rate
JKL     rate1a
JKL     rate2b             I'm trying to keep the "meas" column as the top node attribute, with the "data_elements" as attributes of the children of "meas"
In short, I'm looking for the following output, but, well..keep coming up short.
<meas id="ABC">
     <data_elements>
        <data_element id="rate">
            <rpt>false</rpt>
         </data_element>
    </data_elements>
</meas>
<meas id="DEF">
     <data_elements>
          <data_element id="rate1">
               <rpt>false</rpt>
          </data_element>
                 <data_element id="rate2">
               <rpt>false</rpt>
          </data_element>
          <data_element id="rate3">
                  <rpt>false</rpt>
          </data_element>
     <data_elements>
</meas>
.....and so forth...I'm having trouble with getting the multiple rows of 'data_element' under 'data_elements', and under the single 'meas' one node, any suggestions? My code keeps generating multiple rows. The rpt node is a constant value of 'false'
Thanks

You have to group, and aggregate using XMLAgg :
SQL> set long 5000
SQL>
SQL> with sample_data (meas, data_element) as (

4    select 'DEF',     'rate2' from dual union all
5    select 'DEF',     'rate3' from dual union all
6    select 'GHI',     'rate'   from dual union all
7    select 'JKL',     'rate1a' from dual union all
8    select 'JKL',     'rate2b' from dual
9 )
10 select xmlserialize(content
11           xmlagg(
12             xmlelement("meas",

I think you want an OUTER JOIN

WHERE PATIENT_NUM = HMTLY_PATIENT_NUM (+)
AND PATIENT_NUM = DLC_PATIENT_NUM (+)
AND PATIENT_NUM = &PATIENT_NUM;Edited by: shoblock on Nov 5, 2008 12:17 PM
outer join marks became stupid emoticons or something. attempting to fix

Converting Oracle XML Query Result in Java String by using XSU

Hi,
I have a problem by converting Oracle XML Query Result in Java
String by using XSU. I use XSU for Java.
For example:
String datum=new OracleXMLQuery(conn,"Select max(ps.datum) from
preise ps where match='"+args[0]+"'");
String datum1=datum;
I become the following error:
Prototyp.java:47: Incompatible type for declaration. Can't
convert oracle.xml.sql.query.OracleXMLQuery to java.lang.String.
Can somebody tell me a method() for converting to solve my
problem??????
Thanks

Hmmm.. Pretty basic just look at the example:
OracleXMLQuery qry = new OracleXMLQuery(conn,"Select max(ps.datum) from preise ps where match='"+args[0]+"'");
String xmlString = qry.getXMLString();

Cooresponding Lists Names/Values XML Query

Let's say there is an XML Schema that has
<element name="mt" minOccurs="0" maxOccurs="unbounded">
<element name="r" minOccurs="0" maxOccurs="unbounded">
And for each measurement type (mt), you have a cooresponding measurement value (r). There are additional elements between these two lists. The actual XML data would look similiar to
<mi>
     <mts>20061117100000-0800</mts>
     <gp>900</gp>
     <mt>MeasurementType1</mt>
     <mt>MeasurementType2</mt>
     <mt>MeasurementType3</mt>
     <mt>MeasurementType4</mt>
     <mt>MeasurementType5</mt>
     <mt>MeasurementType6</mt>
     <mt>MeasurementType7</mt>
     <mv>
          <moid>Identifier</moid>
          <r>58</r>
          <r>62</r>
          <r>43</r>
          <r>45</r>
          <r>43</r>
          <r>14</r>
          <r>29</r>
          <sf>FALSE</sf>
     </mv>
</mi>
The first occurance of mt corresponds to the first occurance of r, the second cooresponds to the second, et cetra.
The MI element can repeat hundreds of times and there can be many measurementTypes. Now, I'm trying to figure out how I can create an XML query to efficiently handle this. The problem is that the <r> value is within the complexType <mv> and that is on the same level as <mt>. The XML Query would cause a cartesian product if I were to use something like ...
select
extractValue(value(xmldata), '/mi/mts') measurement_time_stamp,
extractValue(value(xmldata), '/mi/gp') granularity_period,
extractValue(value(mt), '/mt') measurement_type,
extractValue(value(mv), '/mv/moid') measured_obj_id,
extractValue(value(r), '/r') measurement_value,
from xmltable
, TABLE(XMLSequence(Extract(value(xmltable), '/mi/mv'))) mv
, TABLE(XMLSequence(Extract(value(mi), '/mi/mt'))) mt
, TABLE(XMLSequence(Extract(value(mi), '/mv/r'))) r
This obviously wouldn't work. I could go and store all the types and values into a column using
select
replace(replace(replace(extract(value(mi), '/mi/mt').getStringVal(), '</mt><mt>', ';'), '<mt>'), '</mt>') measurement_type,
extractValue(value(mv), '/mv/moid') measured_obj_id,
replace(replace(replace(extract(value(mv), '/mv/r').getStringVal(), '</r><r>', ';'), '<r>'), '</r>') measurement_value
from xmltable
TABLE(XMLSequence(Extract(value(xmldata), '/md/mi'))) mi
, TABLE(XMLSequence(Extract(value(mi), '/mi/mv'))) mv
But this wouldn't work once the XML grew over 4000 bytes. So I need a way to extract this data maintaining the correct integrity (avoiding cartesians).
One idea is a pipelined table function but I have concerns about scalability with that method. Is there a way to accomplish this optimally? I have solutions for this but none of them is going to deliver the scalability I am seeking.
I expect the method chosen will probably need to handle a few hundred thousand files per day.
Thanks,

VJ
I'd not seen your XML schema when I worked the original example, so I reverse engineered it from the instance. Unfortunately when I work with your schema, which contains more levels of nested I can't get it to optimize properly
Here's what should work in theory

SQL>As you can see the re-write is not working out in this case. I'll ask development to take a look at it and see if they can solve it. I think it's similar to another bug I've filed...
WRT to your question about transforming. One easy transformation would be to number the nodes.. Eg use XSTL to add an index number to each MT node and each R node and then join on that value.
