XQuery for (CLOB)-XMLType

I would like to know whether XQuery is supporting XMLType (CLOB).
It seems to be possible to apply XQuery on a sqlquery by using the command sqlquery(..) according to FOR $b IN sqlquery(..)
This however throws a parsing excpetion when I use an sql-query that contains the extract statement which is used for CLOBs
Please help !
Below a piece of code that is not running..
FOR $b IN sqlquery("select extract( doc,'/MeasurementSystems/' ).getStringVal() from V34_6jisno7sf3ksve4m5pabk33h1b X")/MeasurementSystems/MeasurementSeries/*

Marcel,
Does the extract work outside of the sqlquery and FOR loop?

Type-mapping not working correctly, get "Unable to find a javaType for the xmlType" WARNING

I'm manually creating a web-services.xml file, and using the autogen ant task to
generate the codec XML/Java classes. The XML definition is provided by SAP.
The ant build.xml file:
<project name="buildWebservice" default="stubgen">
<target name="stubgen">
<clientgen ear="C:\projects\RMIS\ifrrequests\RMIS.ear"
packageName="com.aa.rmis.webservice.client"
clientJar="C:\projects\RMIS\ifrrequests\rmisws-client.jar"
autotype="False" />
</target>
<target name="all" depends="stubgen"/>
</project>
The problem is seen below in the output from Ant. Note the WARNINIG. The problem
is that the xml type cannot be mapped to the Java type.

public int serviceRequest(PaymentRequestCreate request)
System.out.println("Received serviceRequest message");
return 0;
public void testStringRequest(String request)
The web-service.xml file is attached, which contains the schema for the SAP PaymentRequest.Create
object definition.
Another problem I have, which is probably related, is that the service method
that has a complex data type (non-built in data type) is not being deployed into
the WebLogic server. But the other service method that simply takes a String
parameter is.
The steps I took are:
1. Get XML from SAP Interface Repository (IFR) for PaymentRequest
2. Use ant task autogen to generate the request codec classes
3. Create the web-services.xml file by inserting the schema definition and the
mapping file created by the autogen task, and defining the operations
4. Build web-services.war file that contains all autogen compiled class files,
the web-services.xml file, and the service implementation class
5. Build the ear file that holds the web service files
6. Use the clientgen ant task to generate (included above) to generate the client
jar file that should contain the proxy for both of the service methods
Environment:
* WebLogic 7.02
* JDK 1.3.1_06
* JBuilder 9 Enterprise
* Ant 1.4
Possible causes:
* Namespace not being used correctly
* copied verbatim the mapping xml file generated by autogen into the web-services.xml
file
* xml-schema part of web-services.xml might not be set correctly
* operation definition might not be using the correct namespace
* Classpath used for ant might not be right
* Doubt this is the problem, but I'm out of other ideas
* Set by using the setWLEnv.cmd file provided by WebLogic
* Tried adding the generated classes directory for my project to the classpath,
but did not work
I've been referencing the Programming WebLogic Web Services document throughout
this entire process. I must be missing something.
Can anybody from BEA help me out with this problem?
Thanks in advance.

Hi JD,
I spent a few cycles looking over your web-services.xml file, however I
don't have any suggestions other that one that looks like you have
already tried, at the top, in the <schema...>
targetNamespace="urn:sap-com:document:sap:business"
Making edits to these generated files can be tricky and my only
suggestion is to create a small reproducer to run by our outstanding
support team.
A quick look at our problem database shows one issue (CR095109) related
to a similar problem at deploy time that was fixed with 7.0SP3. Again,
the support folks will be able to help focus in on the issue.
Regards,
Bruce

SQLloder scripts not getting generated for CLOBs

I am trying to migrate MYSQL 3.23 database into Oracle 8.1.7 and after creating the Oracle model and after converting the MYSQL text datatype into CLOB of the Oracle model the SQLloader scripts is not getting generated for CLOB datatypes. I mean the scripts are getting created but there is no change in the script for CLOB datatype.
The script generates the following for the table containing CLOB datatypes:
mysqldump -h <HOST> -u <USERNAME> -p<PASSWORD> -T <DESTINATION_PATH> fields-terminated-by="<ec>" lines-terminated-by="<er>" test av_wbt_course
Please let me know how to load data when the datatype is of CLOB ?

I was able to resolve this issue by using OWM Oracle Migration instead of using offline method by sqlloader scripts.

Limitation for CLOB columns? - ORA-01704: string literal too long

Hello!
I'm trying to update a CLOB column with more than 35000 characteres, but I get "ORA-01704: string literal too long".
The code:
declare
l_clob clob;
begin
update test set test = empty_clob()
WHERE ID = 1
returning test into l_clob;
dbms_lob.write( l_clob, length('A...here 35000xA...A'), 1,'A...here 35000xA...A');
end;
Is there any limitation for CLOB columns?
Thanks for help.

You can use Saxon to execute XQuery expressions.

Problem w. hash-value calculation for CLOB with DBMS_UTILITY.GET_HASH_VALUE

Hello Oracle-Experts,
I had to calculate hash-values for a corrorponding CLOB-field (see my post 'Buffer to small ORA-22835 error after migration from 9i to 10g' in forum 'database general').
I calculate the hash-values with the DBMS_UTILITY.GET_HASH_VALUE, e.g:
     SQL> SELECT DBMS_UTILITY.GET_HASH_VALUE(LPAD('X',3998,'X'),1,POWER(2,30)) FROM dual;
     DBMS_UTILITY.GET_HASH_VALUE(LPAD('X',3998,'X'),1,POWER(2,30))
     1053896858
Because the calculation failed with 10g I had taken a closer look at this function and realised the following results:
VALUE                                             DBMS_UTILITY.GET_HASH_VALUE(VALUE,1,POWER(2,30))
LPAD('X',3997,'X') 557754150
LPAD('X',3998,'X')      1053896858
LPAD('X',3999,'X')          888036750
LPAD('X',4000,'X') 162062978
LPAD('X',4001,'X')          162062978
LPAD('X',4002,'X') 162062978
LPAD('X',10000,'X') 162062978
It seems to me that I can't use this function for clob-values with a length greater than 4000 characters because of collisions. Maybe someone with experience
can give me a hint to handle this problem. Worst case i had to write my own CLOB_2_HASH function.
TIA + Best regards
Matthias

Yeah, the 4000-byte limit would be a factor in working CLOBs. I if you only had 4000 bytes you would not need a CLOB in the first place.
If you don't find something better then writing your own function might be the thing to do.

Your second example has the parameters reversed. The amount (length) comes first and then the offset:
DBMS_LOB.SUBSTR (
   lob_loc     IN    BLOB,
   amount      IN    INTEGER := 32767,
   offset      IN    INTEGER := 1)
RETURN RAW;
DBMS_LOB.SUBSTR (
   lob_loc     IN    CLOB   CHARACTER SET ANY_CS,
   amount      IN    INTEGER := 32767,
   offset      IN    INTEGER := 1)
RETURN VARCHAR2 CHARACTER SET lob_loc%CHARSET;
DBMS_LOB.SUBSTR (
   file_loc     IN    BFILE,
   amount      IN    INTEGER := 32767,
   offset      IN    INTEGER := 1)
RETURN RAW;Also, remember that # of bytes is not necessarily the same as the # of characters depending on your character set. So 2000 bytes might become 4000 characters. And you have to make sure the BLOB is actually character data and not arbitrary binary data.
Post the results of reversing the parameters and using a smaller chunk size.

Comparison for clob type

Hi All,
Can Anyone please tell how to compare clob type in select query with where condition ?
Ex: field: Desc_ short(Clob )
field ean_code(number,pk)
And i want to see those ean_code list matching to particullar clob pattern matching in the record in any where in the record.
Please help.
Thanks and regards,
DK.

COMPARE function
This function compares two entire LOBs or parts of two LOBs. You can only compare LOBs of the same datatype (LOBs of BLOB type with other BLOBs, and CLOBs with CLOBs, and BFILEs with BFILEs). For BFILEs, the file must be already opened using a successful FILEOPEN operation for this operation to succeed.
COMPARE returns zero if the data exactly matches over the range specified by the offset and amount parameters. Otherwise, a non-zero INTEGER is returned.
For fixed-width n-byte CLOBs, if the input amount for COMPARE is specified to be greater than (4294967295/n), then COMPARE matches characters in a range of size (4294967295/n), or Max(length(clob1), length(clob2)), whichever is lesser.

APEX BUG ? Buffer too small for CLOB to CHAR or BLOB to RAW

Hi
I tried use search field (right top corner) in Application Builder for my APP. After while a had:
report error:
ORA-22835: Buffer too small for CLOB to CHAR or BLOB to RAW conversion (actual: 8000, maximum: 4000)
I changed my main table and now I would like search every appearance in app, I thought it's the best solution to use search.
Do you know how resolve my problem.
APEX ver 4.0.1.00.03

You can't...there's a limit of 4k for any page item in apex....attempting to convert or bring in more into a page item or even from an app process into a javascript variable, kicks that error.
It's a limitation with mod_plsql, there's a fix in 4.0 but it requires using the java listener instead of mod_plsql.

What control i can use for Clob datatype in forms?

Hi,
Backend side
I had created a table that having a column namely sql_text which hold the query string and defined as CLOB data type.
On Form 6i
Just i created a textitem(long) for the clob datatype field
but it only hold very limited length of charter, i want to be more. Any other control is there?
please guid me what should i want to do.
kanish

There is limited support for CLOBs in Forms. I guess you could read it in piecemeal with a procedure using the DBMS_LOB package

How to create an XQuery for an XML type data source

Hi,
1.I have data contained in an XML format.
Hence I have created a physical data source for XML type data.
2.I have created a logical view to broker data from several disparate physical data sources.I have called this as UnifiedView.
3.I have created a function called getUnifiedView() to obtain data from all the physical sources
4.Upto this point, I have not faced any problems.
5.However when i try writing a simple XQuery for the physical XML datasource such as
$Sh-data/PublicIdentifiers/MSISDN="1234567"
I get result as (For example):
<HSS>
<MSISDN> 1234567 111111 222222 </MSISDN>
</HSS>
Could you please help me getting the where clause output?
I have attached the schema and XML files used for further information.
Regards
Vidya

Hi mReiche,
I later on resolved the previously mentioned error and try out the XQuery as suggested by you.
for $MSISDN in ns0:Sh-data()/PublicIdentifiers/MSISDN
where $MSISDN="1234567"
return
<HSS>
<MSISDN>{data($MSISDN)}</MSISDN>
</HSS>
It works! Thanks.
Now i am trying to retrieve data from 2 XML documents and an LDAP query.
I have the following data sources:
1.LDAP queried by Java Function
2.HSS xml
3.Presence xml
I want to match the telephoneNumber of the LDAP with MSISDN in the HSS.xml.
Next i want to match the SIP_URI in the HSS.xml with Contact of the Presence.xml
Given below is the XQuery which i have written to achieve the above:
for $x0 in ns5:FindDN($str_mailId)
for $Sh-Data in ns2:Sh-Data()
where $x0 = $Sh-Data/PublicIdentifiers/MSISDN
for $presence in ns3:presence()
where $Sh-Data/Sh-IMS-Data/SCSCFName = $presence/ns4:tuple/ns4:contact
return
On executing this XQuery i am getting the following error:
java.lang.NullPointerException: null

XQUERY against an XMLTYPE variable

I have a procedure which gets xmltype instance and i have to use xquery upon that variable.
declare
myxml xmltype;
s varchar2(20);
begin
myxml:=xmltype('<person><name id="1" age="23"/><name id="2" age="25"/></person>');
SELECT
XMLQuery(
'for $i in /person
where $i/age > 24
return $i/id'
PASSING myxml RETURNING CONTENT) into s
FROM DUAL;
end;
BUT i get this error
ORA-06550: line 6, column 1:
PLS-00801: internal error [*** ASSERT at file pdw4.c, line 793; Cannot coerce
between type 43 and type 30; anon_68F441E0__AB[6, 1]]
Please help it is urgent

Not sure if you ever received your answer regarding how to pass an XMLType variable in PLSQL to an XQuery command.
Here is an example of what I've been using... in Oracle 10.2.0.1
SET SERVEROUTPUT ON SIZE 200000
DECLARE
l_result XMLType;
l_xxDoc XMLType := XMLType(
<root>
<things>
<somestuff>12345</somestuff>
<morestuff>12345</morestuff>
</things>
<things>
<somestuff>dfgdfg</somestuff>
<morestuff>werwer</morestuff>
</things>
</root>
PROCEDURE printClobOut
(p_result IN CLOB)
IS
v_xmlstr VARCHAR2(32767);
v_line VARCHAR2(2000);
BEGIN
v_xmlstr := DBMS_LOB.SUBSTR(p_result,32767);
LOOP
EXIT WHEN v_xmlstr IS NULL;
v_line := SUBSTR(v_xmlstr,1,INSTR(v_xmlstr,CHR(10))-1);
DBMS_OUTPUT.PUT_LINE('| '||v_line);
v_xmlstr := SUBSTR(v_xmlstr,INSTR(v_xmlstr,CHR(10))+1);
END LOOP;
END;
BEGIN
select XMLQUERY(
'for $a in $TheDoc/root
return <theresult>
{$a/things}
</theresult>
PASSING l_xxDoc as "TheDoc"
RETURNING CONTENT) into l_result
from dual;
printClobOut(l_result.extract('/').getClobVal());
END;

DB Link between Oracle 10g and Oracle 9i for CLOB data type

How do I transport XMLType or CLOB from oracle 9i to Oracle 10G using DBLink?
Is any restrction to DBLink, while transfering CLOB with XML data from oracle 9i to Oracle 10G?
Please let me know how i resolve this issue.
Thanks in advance.
DK

Well... it depends on what type of link you wish to create.
If you have same user with same password on both databases (9i and 10G), then you can create a public database link as
CREATE PUBLIC DATABASE LINK dblink USING 'dbalias';
Note: dbalias is the value from your TNSNAMES.ORA. The database from which you are creating the db link has to have the entry in TNS for other database.
Other method is to create a private db link
CREATE DATABASE LINK dblink CONNECT TO user IDENTIFIED by pwd using 'dbalias';
The number of open connections from a particular database is governed by init parameter DB_LINKS (this was in 8i.. not sure about higher versions)
HTH...
