JDeveloper, Java & XML :: How To Get Metadata Of All Fields In SQL Query
Feb 22, 2012
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.
To use dynatree (URL] I want the result to be in the xml form.but the result is not what I want.
SELECT XMLELEMENT("div",xmlattributes('tree' AS "id"), (SELECT DBMS_XMLGEN.getXMLType( DBMS_XMLGEN.newContextFromHierarchy(' SELECT LEVEL, case when CONNECT_BY_ISLEAF = 0 then
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
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 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
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
"java.lang.RuntimeException: org.hibernate.HibernateException: Errors in named queries: getchequeno"
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
i got problem that i want to know Metadata in my Oracle DB 2 version there're OracleDB 9i and OracleDB 10g ,So i want to know about sql command to show all metadata of these Database, because i want to list My metadata and improve to Metadata's Standard(ISO/IEC 11179). How can i show all metadata of these database. is it the same sql command line with this 2 version Database to show all metadata?
oracle PL/SQL. I have almost finished this xml parsing task but their is one problem. Actually in our table there are more than 70-80 columns & due to that only I don't want to put the hard coded column name in my procedure, because if I will do that, the unnecessary procedure size will be increase(means line of code).Here is our procedure
Create or replace procedure loadMyXML(dir_name IN varchar2, xmlfile IN varchar2) AS l_bfile BFILE; l_clob CLOB; l_parser dbms_xmlparser.Parser; l_doc dbms_xmldom.DOMDocument; l_nl1 dbms_xmldom.DOMNodeList; l_nl2 dbms_xmldom.DOMNodeList; l_n dbms_xmldom.DOMNode; node1 dbms_xmldom.DOMNode; l_colName VARCHAR2(100); [code]...
We need to get the single node with class type ="1" from this XML as given below.At any point of time, there will be only one such tag with classType="1". Its position could be anywhere inside the "GroupDetails" Tag.ie, The query should get the tag irrespective of its position inside "GroupDetails".
<info groupId="128" classType="1"/>
Is there any way using EXTRACT function with 3 parameter? I tried but with failure.
with rec AS ( select XMLTYPE( '<connection value="0"> <GroupDetails> <info groupId="100" classType="0"/> <info groupId="128" classType="1"/>
I Have got a requirement where we have to generate an xml conforming to a particular XSD.
What i will be having already in place is an XSD document.
We are thinking of making a procedure which will be recieving the set of inputs required for creating that xml.(Data content of that XML.)We would have to make the XML according to that XSD.
Everytime Parsing the XSD is not feasible.We are looking at a solution which would be easy to make the xml from xsd at runtime.These values (DATA) will be available at run time.
i am using this syntax but its going in error, <?if:number(DAY_1)>=1 and number(DAY_1)<=25?><?attribute@incontext:background-color;'LightGreen'?><?end if?>
