JDeveloper, Java & XML :: Query A Column Containing XML Formatted Data
Jun 26, 2011
how to use dbms_xmlgen to take the results of a query and convert it into a XML formatted data. But if a column (clob) contains data in an XML format, is there a way to query that column and easily parse the data? I know that I could write loops that do string searches for each of the XML tags and nested tags.
I need to get all rows where node <operationStatus> value as SUCCESS. I am running following query but it is returning null value insted of data of columns
SELECT a.MESSAGECONTENTS.extract('/clHeader/msgName/object/msgType/sender/senderInstance/operationStatus/text()').getStringVal() FROM Table_xml_tmp a WHERE a.MESSAGECONTENTS.extract('/clHeader/msgName/object/msgType/sender/senderInstance/operationStatus/text()').getStringVal()= 'SUCCESS'
I have a CLOB column called XML_DATA that has (not-surprisingly) xml data in it that's housed inside a table called HMS_XML_TRANSFER. It has been giving me a headache because I'm unable at this point to use the xml field as a condition to get its TRANS_SEQUENCE number. The where clause doesn't work.
SELECT TRANS_SEQUENCE, XML_DATA FROM HMS_XML_TRANSFER WHERE EXTRACTVALUE(XMLTYPE (XML_DATA), '/INTERFACES/INTERFACE/BODY/IFI0057[ACTIVITY_CODE = "2201-020742"]');
The only test that I have been able to get working is the one below.
SELECT TRANS_SEQUENCE, EXTRACTVALUE(XMLTYPE (XML_DATA), '/INTERFACES/INTERFACE/BODY/IFI0057/ACTIVITY_CODE') FROM HMS_XML_TRANSFER WHERE TRANS_SEQUENCE = '8191602';
It will give me the ACTIVITY_CODE element so I know I can pull data from the XML but I can't do the reverse in the first example which is what I need because I don't know the TRANS_SEQUENCE number, I just know the ACTIVITY_CODE.
I have over 202 error messages logged in Teradata SQL from my many and varied attempts to get this to work using every example I could find online.
As an example this has not worked either...
WHERE EXISTNODE(XML_DATA, '/INTERFACES/INTERFACE/BODY/IFI0057[ACTIVITY_CODE = "2201-020742"]') = 1;
So the question... How do I properly form my SQL statement so I can use the XML column's ACTIVITY_CODE element to get the TRANS_SEQUENCE column field? Oh and I'd like to see both columns in the result.
Below is the version of Oracle I'm using, the description of the Table HMS_XML_TRANSFER, and a sample of the XML that comes from XML_DATA. I can't seems to get tabs working.

I am using the dbms_xmlgen.getXMLfunction to get the result of any query in xml format.
With this XML I also want the metadata information about all the fields used in the query (passed to getXML function). Is it possible and how can I achieve this.
I tried to Google it but couldn't find any solution , it's easy to do it in java where I can get the resultset meta data from the resultset but I have to do it in Oracle function since I want the result in xml format and want to use the oracle XML API.
You may think why I need metadata , the reason is the application will later use this information to sort the data contained in these fields according to their data type provided to.
I am using an oracle 11g database. I have an XML document named test_table.xml stored in table TEST_CLOB, Ex: TEST_CLOB(ID NUMBER, XML_DOC CLOB)
Here are the contents of test_table.xml file.
<xml version = "1.0"" ?> <! DOCTYPE main [ <! Element main (DATA_RECORD*) > <! COLUMN1?, COLUMN2?, COLUMN3, COLUMN4?, COLUMN5, COLUMN6?, GEOM?) +> <! ELEEMENT COLUMN1 (#PCDATA)> <! ELEEMENT COLUMN2 (#PCDATA)>
[code]....
I need a database procedure where I will pass in COLUMN1, COLUMN2 AND COLUMN3 values and it should return all the columns from the xml document. ie. ex: below is what I would like to query
select column1, column2, column3 column4 column5, column 6 from the TEST_TABLE.XML ---- XML DOCUMENT FILE NAME WHERE column1 = 'ARENAS' AND column2 = 'NBA' AND column 3 = 'UNITED CENTER';
INSERT INTO CFL VALUES (11, 1, 'JAN-10', 10); INSERT INTO CFL VALUES (21, 1, 'FEB-10', 20); INSERT INTO CFL VALUES (31, 1, 'MAR-10', 10); and so on (12 records for a year with same quota_id, e.g. here it is 1) [code].......
Also this column values period is dynamic.. it can be for any year.
The select will return values like
Select per_id, PERIOD, amount from cfl where quota_id = 1
Basically 12 rows will be the output: per_id period amount 1 JAN-10 10 1 FEB-10 20 1 MAR-10 10 ..............and so on

i tried to get this xml data in html table but the table was not displayed. When I changed the <ROW> tag into any other tag say <CD> the table was displayed.
Our company database is Oracle based and we use SQL Developer to pull out needed data.Using a snippet borrowed from a co-worker, I have put together a query that, among other things, pulls a list value out of an xml clob field and displays it in the query results. My query as it stands right now is below, followed by an example snippet of the xml clob that I am pulling from. The reason for the "query within a query" is because the base query could return multiple entries and I only want the one with the most recent date.
select * from (Select Wtr_Service_Tag, Wtr_Tran_Origin, Wtr_Send_Date, Wtr_Receive_Date, to_char(substr(wtr_req_xml,instr(substr(wtr_req_xml,1,8000),'SID')+8,12)) Asset_Tag from ws_transactions Where Wtr_Service_Tag In ('20458749610') And Wtr_Req_Xml Like ('%CSM%') Order By Wtr_Receive_Date Desc) where rownum = 1; [code]....
This query is only able to pull the first value in the list.How can I edit this query to pull all of the list items when there are more than 1 (preferably concatenated into one column in the query results)? I have another field, in a separate table, that I can pull from to get the number of list items.
This one may be more complex. As currently written, the query pulls a fixed number of characters from the xml clob and either returns not enough data, or too much because the values I need to pull could be of varying lengths. I have no way to query what those lengths might be.
I have two separate databases, I want to send XML file contains a query from one to the other , that read query and return results to a first via XML file.
I have a requirement to extract data from an XML formatted string that is passed as an IN parameter to a database stored procedure. I do not have a table to store the XML, nor an XML schema, nor a namespace, just the XML string. While new to XML, I do understand the basics. Using XMLTable I am able to parse out the simplest of XML data. My problem is this; attempting to extract data from nested XML nodes results in the error
Testing a solution example I found on this site by Barbara Boehmer, I still get the ORA-19279 error. I suspect it may be because I have version 10g while she has version 11g. Her solutions is from #msg_514154. Here is that code that gives me the error:
SCOTT@orcl_11gR2> SELECT x."deptno" 2 FROM (SELECT '<departments><deptno>1</deptno><deptno>2</deptno></departments>' col FROM dual) xml_data, 3 XMLTABLE 4 ('/departments/deptno' 5 PASSING XMLTYPE (xml_data.col) 6 COLUMNS 7 "deptno" number path '/deptno') x 8 /
deptno ---------- 1 2
2 rows selected.
As I said, this example generates the ORA-19279 error. Need processing XML data from an IN parameter?
The data in the MESSAGE_DATA column contains text but also control characters that separate data elements in the message (i.e (char)31, (char)29) and (char)28) . What i am finding is that for some reason message.getString() is sometimes truncating the message. I can read the majority of messages but some of them are truncated. Am i supposed to be reading the data using a different method? If so how?
I have tried to use sqlplus to look at the data in the database and it is all there it is just truncated by the message.getString() method. I saw this when i tried to output the result i.e. System.out.println(message.getString()).
I ran an sql query using the length() function in Oracle and length("MESSAGE_DATA") returns 2032 whereas in java message.getString(1).length() returns 2000.
I'm trying to call a Java function from within a PL/SQL aggregation function with a (array of) complex data type.
a) basic definitions (work and are ok)
CREATE OR REPLACE TYPE eventtype AS OBJECT ( relevance NUMBER, bid1 NUMBER,tid1 NUMBER,prob1 NUMBER, bid2 NUMBER,tid2 NUMBER,prob2 NUMBER, bid3 NUMBER,tid3 NUMBER,prob3 NUMBER, bid4 NUMBER,tid4 NUMBER,prob4 NUMBER, bid5 NUMBER,tid5 NUMBER,prob5 NUMBER, bid6 NUMBER,tid6 NUMBER,prob6 NUMBER ); CREATE OR REPLACE TYPE eventtuple IS TABLE OF eventtype; /
b) The following call works (but is not exactly that what I want):
public class pcompDP { public static NUMBER probComputation(oracle.sql.STRUCT pin) throws java.sql.SQLException { ... } } create or replace FUNCTION pcompDPFunc(cin IN eventtype) RETURN NUMBER PARALLEL_ENABLE DETERMINISTIC AS LANGUAGE JAVA NAME 'pcompDP.probComputation(oracle.sql.STRUCT) return BigDecimal'; / SELECT pcompDPFunc(eventtype(5, 6, 0.3, 10, 20, 0.45, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0)) from dual;
c) The following call doesn't work (but should have the intended semantics):
public class pcompDP { public static NUMBER probComputation(oracle.sql.STRUCT[] pin) throws java.sql.SQLException { ... } } create or replace FUNCTION pcompDPFunc(cin IN eventtype) RETURN NUMBER PARALLEL_ENABLE DETERMINISTIC AS LANGUAGE JAVA NAME 'pcompDP.probComputation(oracle.sql.STRUCT[]) return BigDecimal'; / SELECT pcompDPFunc(eventtuple(eventtype(2, 3, 0.234, 1, 1, 0.123, 0, 0, 0, 0, 0, 0, 0, 0, 0), eventtype(5, 6, 0.3, 10, 20, 0.45, 0, 0, 0, 0, 0, 0, 0, 0, 0))) from dual;
d) What's the error? Do I have to use JPublisher or is it possible without it? I guess an array should be possible without it.
The type of the parameter seems to be wrong. Question is whether in PL/SQL, Java or SQL.
I am trying to invoke program from my local Windows machine (exactly java executor, which is in my environment on c:javajdkinjava) using database package with Java stored procedure.
Everything is fired by SQLPLUS script, this script invokes package with Java stored procedure (jar loaded into Oracle) and that procedure is trying to invoke runtime process (syntax:
c:javajdkinjava -cp
and here ara my classes and main jar) using my local java executor. I added all permissions using dbms_java.grant_permisions (execution forced me to give permissions java.io.FilePermission to <<ALL_FILES>> for execute), moreover I added to my database user JAVASYSPRIV and JAVAUSERPRIV role. Unfortunately, beside this I am still getting error:
C:javajdkinjava not found (Note that lookup with PATH isn't done due to the oracle executable being setuid.)
I am writing a java stored procedure in my package. In the java procedure I want to issue a query to be fired on the user table from which I am calling the java procedure.
Some thing like following:
I am logged in to USER1 and my package is inside USER1. From this package I am calling the Java Stored Procedure. In java procedure I want to make a jdbc connection to USER2. The details of USER2(password, hostname,portno) are stored in a table called 'connection_details' and this table is in the USER1.
My problem is how can I issue the
SELECT details FROM CONNECTION_DETAILS for USER2
so that i can get the details..?
Do i need to first make jdbc connection to USER1 and then execute the above query for which i need similar details of USER1. How can i obtain the details of USER1 here.
I am thinking if I am already in USER1 then do I need to make the jdbc connection to USER1 and then execute the query?
I've this java source create or replace and compile java source named "Decodificador" as public class Decodificador { public static String decodifica(String codigo) return codigo;
and this function

when I execute the function the result is:
ORA-29531: no method decodifica in class Decodificador
