Dynamically Build (recursive) Xml SQL Statement
May 3, 2013
We have an requirement to create xml data for entire database (selected tables) which are in hierarchy.Procedure should read node_mapping table having parent and child tables relationship info and build XML Select statement.
Currently it is building SQL statement whenthere are one parent having multiple childrens i.e Dept having emp, emp_act, emp_rsch..but when child node are having childrens then it is not working - it has to repeatedly call this procedure (recursive) and build below given SQL statement.
1. To change procedure to build xml sql statement when there are multiple childrens to child nodes (hierarchy)
2. To format the output in xml data
We are using ORACLE 11G and WINDOWS 7
CREATE TABLE node_mapping
(
NODE_ID NUMBER(5) PRIMARY KEY,
PARENT_NODE VARCHAR2(100),
CHILD_NODE VARCHAR2(100),
PARENT_NODEID VARCHAR2(50),
CHILD_NODEID VARCHAR2(50)
[code]....

We have an requirement to build (XML) Select statement dynamically based on the mapping table (which is in hierarchy format)
I have removed xml keyword, so query will not work. but need procedure which will recursively check mapping table (parent and child table) and build below given select statement.
Example 1:
SELECT dname,
(select ename,

We have developed a code which builds a trigger on a atble dynamically at run time usinf Dynamic SQL command Execute immediate.
create or replace
PROCEDURE GENERATE_TRIGGER
(
P_TNAME IN VARCHAR2
[Code].....
I am not usre if the error is due to insufficient privileges as we are able to build tabl;e in the system dynamically using the above mentioned command.

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 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.

I need to use Recursive Subquery Factoring for a project of mine, specifically I need to use some code I have found in a function.
[URL]
The code I have so far is this:
create or replace
function recursive
(
pattern in raw
, solution in raw
) return number as
[code]....
But when trying to compile it in Oracle SQL Developer, I get the following two errors:
Error(9,1): PL/SQL: SQL Statement ignored
Error(10,30): PL/SQL: ORA-00907: missing right parenthesis
The errors refer to these two lines:
with x( s, ind ) as
( select sud, instr( sud, '' '' )
I have looked over and over the code again, and I do not see any missing parenthesis. Furthermore I tried using with in a smaller test function:
create or replace function test
(
p in number
)
return number as
v number;
begin
with t(a) as
[code]....
Which compiles just fine, so I'm not sure why that line is being ignored in this function. The whole idea here is to replace the sudoku string in the function with a variable that I built from the two parameters.

I'm trying to build a query capture the below information. Table looks something like below .
RoomSubjectStudentsA1Science10A1Maths20B1Science15B2English25C1Deutsch20A1French15C1English10
How can i write a query so that i takes the average of students in each room and display the output? I need to write a query so that it also picks up any new rooms and students added. Average is sum of total students in room by number of times each room is specified.
eg: A1 is listed 3 times a the result would be 10+20+15 divided by 3.
A1 B1 B2 C115 15 20 15

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.

In MS Windows, if I copy a file and paste it into the same folder, I get a copy with the text 'Copy of' in front of the file name. If I paste it again, I get another copy with a different version number.
E.g.
sqlnet.log
Copy of sqlnet.log
Copy (1) of sqlnet.log
Copy (2) of sqlnet.log
I was wondering if I could copy existing rows into a table and do the same thing?
So, for example if I had this table:
create table tst_srch (srch_is varchar(100), user_name varchar(100), srch_name varchar(100));
insert into tst_srch values (1,'USER1','SRCHA');
insert into tst_srch values (2,'USER1','SRCHB');
insert into tst_srch values (3,'USER1','SRCHC');
insert into tst_srch values (4,'USER1','SRCHD');
insert into tst_srch values (5,'USER2','SRCHC');
insert into tst_srch values (6,'USER2','SRCHD');
insert into tst_srch values (7,'USER2','SRCHD_1');
Could I write a procedure like copy_searches('USER1','USER2') that would copy all USER1's searches to USER2 - including renaming any duplicates.
So it would create these new rows:
8,USER2,SRCHA
9,USER2,SRCHB
10,USER2,SRCHC_1
11,USER2,SRCHD_2
I've looked at various insert statements, merge and match statements and exception handling in procedures .

I am an absolute neophyte at this. I'm fairly good at SQL, but have not administrated a database before.
I am trying to take a backup from our production database and restore it to a fresh install of Oracle 10.2 on a Windows 2003 server using RMAN - but I am not getting very far. Software versions are all the same. I have access to the manuals, but it seems like every link I follow adds more questions than it answers.
I have gone through the wizard and set up oracle on the new box - that all seemed to go smoothly. In order for this to work, do I need to set up the database with the same DBID as the one in the backup files? Or is there a way to import the data from the backup and have it build the database from those files?
I'm not sure I'm even asking the right questions. Do any of y'all know of a tutorial that would walk me through this process step by step?

we get daily a full dump from our customer. We have to build the differences of tables (deltas) and load them in separate tables.
There some questions, requiremenst and restrictions:
1) Is it possible the merge the dumps ?
2) How to build the differences as the easiest ?
3) The whole process (import, merge, extract) should be run in batch.
4) We have only a solid knowledge and liitle time for doing.

select a default table in oracle as we do in teradata, below is the syntax of teradata.
select 'XXX' as Curr,
'BUS OBJ ' as acq_nm
from (select 1 as one) Union
select 'ALL' as Curr, from (select 1 as one).
so I need the same select in oracle.

I want to build a hierarchy and output it into a sub-report. Since the data in few hierarchy fields exceeds 4000 characters and therefore m getting the ORA-01489 error and the entire report was failing.
So i have used user aggregate function to print the out put. I have also used row_number() to print sequence in query output.
the query that i am using is
SELECT pr_id,
REPLACE (REPLACE (twadmin.STRAGG2(distinct RPAD (to_number(curr), 2, ' ') || ')' || NVL (DECODE (medical, NULL, clinical, medical), 'UNKNOWN') || '###' ||
RPAD (' Causality as per rport ', 50, ' ') || ': ' || reporter || '###' ||
RPAD (' Causality as per report2 ', 50, ' ') || ': ' || hospital || '###' ||
RPAD (' Dechallenge', 50, ' ') || ': '|| dechallenge || '###' ||
RPAD (' Rechallenge', 50, ' ') || ': '|| rechallenge), ',', CHR(10)), '###', CHR (10)) causality
[code]......
the output of the query is
ID Causality
-- ------
3755101 )Blisters (Blister)
Causality as per report1: Probable
Causality as per report2: Possible
Dechallenge : Not Applicable
Rechallenge : Not Applicable
2 )Mental status changes (Mental status changes)
[code].......
but the expected out put is
ID Causality
-- ------
3755101 )Blisters (Blister)
Causality as per report1: Probable
Causality as per report2: Possible
Dechallenge : Not Applicable
Rechallenge : Not Applicable
[code]........
but it should be as
1)
2)
3)
..
..
..
10)
11)
12) for the values in the causality field

I have a table:
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

Ive just tried running a simple
update BASIC set 'column name' = NULL
Which works fine if i specify a where clause that returns a low amount of values, but im trying to run this update for the whole column (1000's or records).
Ive had no experience of this error before and am unsure of where to start, ive had a quick read around but see something of removing triggers?
The full error is :
ORA-00036: maximum number of recursive SQL levels (50) exceeded
ORA-06512: at "new.su_Table", line 61

Oracle Version :- 11.2.0.2 I found a error in a trigger(Statement Level) ORA-00604:error occurred at recursive SQL level string. Before Finding this issue,Once the DB Response was slow . Will this be the issue Of DB Slow response. The Above trigger fires for each entry in an transaction table. The code is Patched and was executed . The above issue was found during another issue and not the DB Slow response. My Doubt is Whether DB response slow issue would be because of this. Now after fixing this Slow response was not reported.

I have built a Menu Framework using the following instructions.
[URL]........
I am facing 2 problems.
1. If the user is in a child application and clicks logout. He is taken to the login screen of the master application (Correct), but once he enters login details, he is returned to the child application (False). I think he should be returned to the Home page of the Master application.
2. If I set Session Timeouts in the Edit Security Attributes of the applications. Then if the user is timed out, he is sent to the login screen of the Master application (Correct). If he then logs in, he is sent the the Home page of the Master application (Correct).
Now if he clicks a link to a child application he is then sent back to the Master application login screen. He then has to login again. He is sent to the Master Home page and everything is then ok.

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')
