JDeveloper, Java & XML :: Process XML Data Passed In Parameter
Oct 7, 2011
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?
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 need an example of oracle stored procedure, which should xmltype input parameter. xml type parameter contains multiple records and I need to update them in the database.
Is it possible to pass a nested select statement as a parameter to a procedure? In other words, I am currently successfully doing this:
SELECT BASE_PAY INTO N FROM EMPLOYEES WHERE ID=p_ID; SetPackageValueProc(PkgID,'YearlyBasePay',N); And I'd like to do something along the lines of this: SetPackageValueProc(PkgID,'YearlyBasePay',(SELECT BASE_PAY FROM EMPLOYEES WHERE ID=p_ID));
How to extract the data from XML using the xsd file. attached files.
Explanation: first check the EmailMessage tage from order_conf.xml compared with Email.xml(<xsd:element name="EmailMessage">) if exists then go to next node. EmailMessage(exists tag in order xml file) ->next <ns1:emailNotificationype> this tag should be follow under the EmailMessage tag(<xsd:element ref="emailNotificationype">) in Email.xml ->next <ns1:orderNotification> -> check this tag in <xsd:element name="orderNotification"> in Email.xml. -> next <ns1:templateFormatInfo> -> it should follow under <xsd:element name="orderNotification"> in Email.xml. -> next <ns1:templateFormatInfo> -> it should follow these tages <xsd:element name="templateFormatInfo"> <xsd:element ref="templatecode"/> <xsd:element ref="templateversion"/>
select dbms_xmlquery.getxml('select * from tbl_nm') from dual <?xml version="1.0" encoding="ISO-8859-1"?> <ROWSET> <ROW num="1"> <NAME>admin</NAME> <PASSWORD>a</PASSWORD>
[code]....
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.
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.
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 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 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.
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 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
create or replace function F_Decodificador(codigo varchar2) RETURN VARCHAR2 IS LANGUAGE java NAME 'Decodificador.decodifica(String) return String';
when I execute the function the result is:
ORA-29531: no method decodifica in class Decodificador
I need to call DB function through Java Hibernate.
My Sample XML File looks like. --------------------------------------------------------------- <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping> <sql-query name="getchequeno" callable="true"> ?:=call cz_nab_mw_fn_gen_ol_chq_no() </sql-query> </hibernate-mapping> --------------------------------------------------------------- I am getting below error while reading the file

i`m trying to use pl/sql function to execute java class. I created 2 tables with around 100 values and java class with simple functionality. I need to create function to loop through my table1 and get with each iteration one value from table and pass that value as parameter to java class.
table1 is something like this:
ID NAME 1 name1 2 name2 3 name3 . . . . 100 name100
table2 is empty with same columns as table1 ( table2 is for data obtained from java returns ) I created in sql+ java class.
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED "myClass" AS import java.io.*; import java.util.* public class myClass { public static String fun(String strName)
[code]....
Then i wanna make a pl/sql function for:
1)For i = 1 Obtain first value from table1 (column name) and pass it throught java class then return value and save it in table2 with the same id as id from table1
