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 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?
I want to display result with respective levels. for example p21 ,p30 are coming under first level . p22,p25 ,P31,P32are 2nd level. p23,p24,p26,p27 are 3rd level p28,p29 are FOURTH level item_id's.
Already I 'VE tried using CONNECT BY PRIOR clause.BUT STILL I COULDN'T GET THE RESULT.
I have a hierarchical data structure where a child can have many parents, and a parent can have many childs.See the attached file hierarchy_iliustration.jpg. This example has 4 hierarchy levels, in real problem there can be unlimited number of levels.I want to write a SQL query that lists all indirectly dependent child nodes for a given parent node.
Test structure for example attached:
CREATE TABLE TEST.NODE_T ( ID NUMBER PRIMARY KEY, TEXTAS VARCHAR2(254) );
How to count siblings in a hierarchical query? I'm trying to get a listing of employees
SELECT LEVEL, last_name||', '||first_name AS Manager, count(employee_id) FROM employees START WITH manager_id IS NULL CONNECT BY PRIOR employee_id = manager_id GROUP BY level
This returns 4 levels. I'm wanting to add up the number of siblings under the level 2 instead of listing them all.
That�s generally the format the values would appear in the table if I just did a standard select. I want it displayed in a more hierarchical Parent � child way.
The format I need to get out is as follows: Lvl KeyParKey hasCh 1k101 2k34k10 2k22k11 3k56k220 3k109k221 4k61 k1090 3k67k220 2k24k10 1k200 1k301 2k13k30 2k52k30 2k35k30 2k13k30 1k401 2k11k40

Now I noticed that the subquery is never used to seed the join: indexes - if any - are used. Otherwise a full table scan is performed.In the example - if ESGROUP is indexed, then it's chosen to start the join evaluation. If not, a full table scan is performed.Is there any way to suggest to the optimizer to use the subquery in case there are no indexes - as a fallback ?
In the above example where VERSION_TABLE contains nearly two million records, the no index solution takes 60 secs. vs. less than 1 sec. in the index case.Wrapping the hierarchical query in a inline view leads to same result.
PS: the execution plan (without index) is: ------------------------------------------------------------------------------------------------------------- | Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time ------------------------------------------------------------------------------------------------------------- | 0 | SELECT STATEMENT | | | | 9 (100)| | | 1 | SORT ORDER BY | | 1 | 171 | 9 (23)| 00:00:01 | |* 2 | HASH JOIN SEMI | | 1 | 171 | 8 (13)| 00:00:01 |
creating Oracle SQL query to fetch the information using PIVOT option.We are populating audit table using triggers. For every update, there will be two rows into audit table, one row with all OLD values and another with all NEW values. Also every updated is uniquely identified by Sequence No. Example for phone audit is mentioned below :
CREATE TABLE test_audit_phone ( emplid VARCHAR2(10), seqno NUMBER, action VARCHAR2(3), office NUMBER, mobile NUMBER );
Insert some rows into table.
INSERT INTO test_audit_phone VALUES ('100',1,'OLD',1111,9999) / INSERT INTO test_audit_phone VALUES ('100',1,'NEW',2222,9999) / INSERT INTO test_audit_phone VALUES ('100',2,'OLD',2222,9999) / INSERT INTO test_audit_phone VALUES ('100',2,'NEW',2222,8888) /
Table will look like the following :
SQL> SELECT * FROM sysadm.test_audit_phone ;
EMPLID SEQNO ACT OFFICE MOBILE ---------- ---------- --- ---------- ---------- 100 1 OLD 1111 9999 100 1 NEW 2222 9999 100 2 OLD 2222 9999 100 2 NEW 2222 8888
Now we have to present data in different format. For each field, display OLD and NEW values in column format.
i have many partitions in one table. i need metadata for some of the partitions. We have any option to get the metadata for partitions only.because while selecthing the table meatdata i am getting long script.
I have to build something like an export-interface-mappingtool. So user defines more or less a query and I have to display the attributes of this query to enable a mapping.
If I build up a ref cursor fom this query, I did not find the possibility to read its metadata (mostly Type/length is enough).
What I do not want to do is creating a temp. table or parse the query string to derive it from the dictionary.
Is it possible at all to get the metadata of a dynamic SQL ?
I'm currently busy with database consolidation, so I'm searching for a solution to generate some useful DDL to prepare the new target database before importing the application's data. This should include TABLESPACE DDL and all additional users with their grants.
So first I thought of developing a simple script, which will create the CREATE TABLESPACE DDL but with transformed datafile paths.But my throws some errors and I don't understand why:
ORA-31604: invalid NAME parameter "STORAGE" for object type TABLESPACE in function SET_FILTER declare l_hObject NUMBER; l_Objddl CLOB;
We are migrating one of our databases from linux to AIX (testing phase). We're using transportable tablespace for the same. All steps are done and we're stuck during importing the metadata. While importing metadata we require to mention fully qualified datafile name which has to be plugged. The number of datafiles is 309 and the name of the all the datafiles has to be in one line. Now if we try to write it in one line using vi editor, the editor gives error 'ex: 0602-140'.
Is there a way by which we can overcome this situation?
but it will return me below error, i have only access to user shan our client cant allow me to use system or sysdba schema or any other required grants or privileges so is there any way to take metadata backup of user shan from user shan.

A function returns the comments of all objects of the schema using metadata api. I used DATABASE_EXPORT as object_type for open function. which name (eg: base_object_name, base_object_schema...) should i use to get comments of single object. My code is..
1 CREATE OR REPLACE function f_depen_obj 2 return clob 3 as 4 a number; 5 b number; [code].....
I got comments of all objects when i commented 11th,12th lines. Now i want the comments of EMP table of SCOTT schema. I got the following error ..
SQL> select f_depen_obj from dual; ERROR: ORA-31603: object "EMP" of type TABLE not found in schema "EMP" ORA-06512: at "SYS.DBMS_METADATA", line 1546 ORA-06512: at "SYS.DBMS_METADATA", line 1583 ORA-06512: at "SYS.DBMS_METADATA", line 1901 ORA-06512: at "SYS.DBMS_METADATA", line 3806 ORA-06512: at "SYS.DBMS_METADATA", line 3784 ORA-06512: at "SCOTT.F_DEPEN_OBJ", line 17
no rows selected...i got output (comments of single object) when i use COMMENT instead of DATABASE_EXPORT in open function(line no: 9). But i need to use DATABASE_EXPORT as a object_type. Which name is suitable for set_filter procedure instead of 'NAME'?
I'm using Oracle 11g enhanced ADD COLUMN Functionality. Adding new columns with DEFAULT values and NOT NULL constraint no longer requires the default value to be stored in all existing records.
Sometimes we change DB columns from NOT NULL with DEFAULT to NULL with DEFAULT. This operation "materialize" column default. Is there an easy way (Dictionary view) how to find, that COLUMN default value is stored as metadata or is "materialized" ?

Note:- I got only this that this query is alternative of self join and it is giving manager name along with mgr id for each employee but when it gives output i couldn't able to understand how to identify who is manager of whom. Tell and explain with clause in oracle , i only know it is alternative of inline view but i want to know how does it work and how to use 'WITH' in oracle query if possible.
create table test_circular_data(c1 varchar2(10),c2 varchar2(10)); insert into test_circular_data values ('c1','l2'); insert into test_circular_data values ('c1','l3'); insert into test_circular_data values ('c3','l3'); insert into test_circular_data values ('c4','l3');
commit;
There is a circular relation between columns c1 and c2, so what I'm trying to retrieve is something like that :
c1--> l2 --> l3 --> c3 --> c4
The steps to get that result is :
1.- c1 related to l2 : c1-->l2 2.- c1 related to l3 : c1-->l2-->l3 3.- l3 in the list and related to c3 : c1-->l2-->l3-->c3 4.- l3 in the list and related to c4 : c1-->l2-->l3-->c3-->c4
I have a table which contains the connectivity details. It is telecom data. The table contains the relation between the point features(Ex: Terminal) and linear features(Ex: Cable)
