JDeveloper, Java & XML :: Recursive Hierarchy Query To XML?
Mar 5, 2013
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
We are on oracle 10.2.0.4 on solaris 10. My question is on a sql query. Is it possible to rewrite a query to avoid the connect by and prior constructs and use joins? For example i have the following query:
SELECT empno, ename, job, mgr, hiredate FROM emp START WITH empno in (7566,7698) CONNECT BY PRIOR empno = mgr
How can it be rewritten using a two table join (self join)? I am not sure if it can be done and whether it is possible.
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
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 need to do a PL/SQL program that prints the same that this WITH clause query, without using WITH or CONNECT BY, i was thinking about a solution with cursors?
WITH recursiveBOM (assembly_id, assembly_name, parent_assembly) AS (SELECT parent.assembly_id, parent.assembly_name, parent.parent_assembly FROM bill_of_materials parent
I have the following table structure...............
Main_Head table name
main_head_id ,pk head_desc, head_id , sub_head_id
keys col table ref col sub_head_id main_head head_id
the table is recursive table self join ----------------------------------------- now i want to write the query which return all head_desc which have same head_id
I have this SQL select to give me all the nodes of a tree starting at a particular node:
SELECT tree.node_id, LEVEL depth_level FROM tree_of_nodes nodes START WITH nodes.node_id = 1000 CONNECT BY PRIOR nodes.node_id = nodes.parent_id
I need to update a column called dept_level, which is essentially the same as Oracle's LEVEL. Something like this statement is what I need, but obviously this statement doesn't work:
update tree_of_nodes set depth_level = LEVEL START WITH nodes.node_id = 1000 CONNECT BY PRIOR nodes.node_id = nodes.parent_id
I've tried inline views and other approaches and have not found a method that works.
Is it possible to sort records based on hierarchy in such a way that records sorts in sequence and records of same level comes in the last (in sorting order)
create table FIELDS ( FIELD_NAME VARCHAR2(30) not null, PRG_FIELD NUMBER not null, LENGTH NUMBER );
with
INSERT INTO FIELDS VALUES('FIELD1', 1, 3); INSERT INTO FIELDS VALUES('FIELD2', 2, 3); INSERT INTO FIELDS VALUES('FIELD3', 3, 4); INSERT INTO FIELDS VALUES('FIELD4', 4, 2); INSERT INTO FIELDS VALUES('FIELD5', 5, 1);
I need to insert in a table:
create table STUFF ( FIELD_NAME VARCHAR2(30) not null, FSTART NUMBER not null, LENGTH NUMBER );
And the output I want is:
INSERT INTO STUFF VALUES('FIELD1',0,3); INSERT INTO STUFF VALUES('FIELD2',3,3); INSERT INTO STUFF VALUES('FIELD3',6,4); INSERT INTO STUFF VALUES('FIELD4',10,2); INSERT INTO STUFF VALUES('FIELD5',12,1);
So each field starts where the previous (ordered by PRG_FIELD asc) ends.
I think the query should use both lag and connect by but I haven't had any luck writing it. The problem is that all the examples I've seen around, using connect by prior, utilize 2 fields with different names, es connect by prior emp_id = mgr_id. Instead I should do something like connect by prior prg_field = prg_field-1 but that doesn't seem to work.
PS: I don't necessarily need to do this, I have a guy manually writing the inserts, this is just an exercise I would like to figure out
I am working on the quality center oracle database to write a query that fetches all steps of a test case including the ones having calls to tests. Structure of table is explained below. I've made up an example and attached it as an image to this post. This image also has the expected result of the query I want to write.
Table Name: STEPS (This table contains steps belonging to tests. Some steps are simply calls/links to other tests)
Columns: STEP_ID (primary key - integer) STEP_NAME (char) STEP_DESC (char) ORDER (integer) TEST_ID (reference to table TEST.test_id) [code].......
Referring to the example (see attached image), I'm looking to write a query that gives me all steps (including steps from called tests) of the test - "Empty trash from mailbox" in the correct order.
To start with I can write the following query to get steps of the test - "Empty trash from mailbox". SELECT * FROM steps WHERE test_id = (SELECT test_id FROM test WHERE test_name = 'Empty trash from mailbox')
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"/>
EMP_ID EMP_NAME MANAGER_ID 1 KING 2 STEVE 1 3 FRANK 2
What I want is when I query for any EMP_ID, I want to get all his manager first, and the last record is the employee in leaf of the hierarchy in the query.
For example, when I query for EMP_ID=2 ,I want to get this result
EMP_ID EMP_NAME MANAGER_ID 1 KING 2 STEVE 1
and when I query for EMP_ID=3 ,I want to get this result:
EMP_ID EMP_NAME MANAGER_ID 1 KING 2 STEVE 1 3 FRANK 2
