Columns to rows in oracle 10g

Hi,
I need the output from columns to rows in oracle 10g.
this is my original output using some select query,
select a.created_by,b.modified_by from created_tp a,modified_tp b where a.col_id=b.col_id.
created_by modified_by
Siva Raja
but i need this same output by rows like
user--anything fine
Siva
Raja
Thanks
Siva

Hi,
select case l when 1 then a.created_by
else b.modified end
from created_tp a,modified_tp b, (select level l from dual connect by level <= 2)
where a.col_id=b.col_id.

Hi,
Cross-join your table with a Counter Table , a table (or result set, as in the example below) that counts from 1 up to the number of columns you want to unpivot, like this:
WITH     cntr     AS
     SELECT     LEVEL     AS n
     FROM     dual
     CONNECT BY     LEVEL <= 3     -- Number of columns to be unpivoted
SELECT       s.bu_id
,       s.prod_id
,       CASE c.n
          WHEN 1 THEN 'total_clients'
          WHEN 2 THEN 'total_men'
          WHEN 3 THEN 'total_women'
       END          AS client_info
,       CASE c.n
          WHEN 1 THEN total_clients
          WHEN 2 THEN total_men
          WHEN 3 THEN total_women
       END          AS values
FROM            source_table s
CROSS JOIN     cntr           c
ORDER BY s.bu_id
,            s.prod_id
,       c.n
;If you'd care to post CREATE TABLE and INSERT statements for your sample data, then I could test this.
The values column that you create can only have 1 data type. If the original, unpivoted columns have different data types, you may need to convert some of them in the CASE expression that defines values.

Columns Display Support in Oracle 10g Express Edition..................

I am working with the Oracle 10g Express Edition, and I Created a Table with 52 Fields and even successfully inserted data into the table via Java Program. But the problem is when I am displaying the table from the Oracle 10g Express Edition Interface, it is displaying only first 31 Fields and displaying "<div class="fielddata">First 31 columns displayed.</div>". What should i do if I want to display all the 52 columns. Awaiting for the Reply. Thank You..

Auto-increment identity column through procedure in oracle 10g on windows

Hi,
I need identity primary key which should be auto increment before while inserting data into table.
for this i had use sequence and then trigger to increment it.
but now i need to increment it in Procedure, while my procedure is having code to insert data in same table which has primary key

Unfortunately, Oracle does not have auto-increment columns. A sequence is an auto-increment object, and it's the right way to automatically generate unique identifiers, but you need to explicity reference the sequence, either in you DML statements, or in a trigger that will automatically fire before a DML statement.
but now i need to increment it in Procedure, while my procedure is having code to insert data in same table which has primary keyAre you saying that you need to increment the sequence, completely aside from INSERTing into the table?
If so, just reference sequence_name.NEXTVAL wherever you want to. In PL/SQL, you can say
SELECT sequence_name.NEXTVAL
INTO number_variable
FROM dual;This works in any version of Oracle, but starting in Oracle 11, you also have the option of referencing te sequence without using dual, or any other table.
I hope this answers your question.
If not, post a complete script that people can run to re-create the problem and test their ideas.
For example:
-- Here are the table and the seqauence that I created:
CREATE TABLE table_x ...
CREATE SEQUENCE ...
-- Here is the BEFORE INSERT trigger I wrote:
CREATE OR REPLACE TRIGGER ...
-- The trigger works exactly how I want it to in statements like this:
INSERT INTO table_x ...
-- So there are no problems (that I know of) with anything up to this point.
-- Now I want to use the same sequence to ...

Getting the ROWIDs of non-duplicate rows in Oracle 10g

Hi,
given a table TAB1 in which the primary key is composed of these first 3 columns:
================================================
colA____________colB_________________colC____________________colD
================================================
AA-----------------------01-----------------------20080101-----------------------100
BX-----------------------32-----------------------20050325-----------------------366
AA-----------------------01-----------------------20080102-----------------------645
AA-----------------------01-----------------------20080707-----------------------765
AB-----------------------02-----------------------20080806-----------------------336
AB-----------------------02-----------------------20080705-----------------------543
I wish to be able to find the ROWIDs of those rows where colA||colB occurs only once in the table TAB1.
So in the above example, I would want to know the ROWID of the row containing colA=BX and colB=32 as "BX32" occurs only once in this table (AA01 occurs 3 times, AB02 occurs twice so I'm not interested in them).
The following does work, but it is too SLOW:
select ROWID from TAB1 where colA||colB = (select colA||colB from TAB1 HAVING COUNT(*)=1)
Can anyone please suggest an efficient way to find this unique ROWID value in these circumstances?
Edited by: Nemesis on Nov 29, 2008 2:50 AM

Thank you Walter.
This does not give the desired result however. It compares the table, row by row with a 'mirror' of itself and says 'give me the rowid of the row where its mirror does not match itself' (correct me if I am wrong)
(Here I added the '=' to ' AND d.ROWID = d1.ROWID);'
SELECT D.rowid
FROM TAB1 D
WHERE NOT EXISTS (SELECT *
FROM TAB1 d1
WHERE d1.COLA = d.COLA
AND d1.COLB = d.COLB
AND d.ROWID = d1.ROWID);
So it returns nothing as all rows match their mirror rows.
However, it gave me the idea of doing the following:
SELECT D.ROWID FROM TAB1 D WHERE (SELECT COUNT(*) FROM TAB1 D1 WHERE X.colA = D.colA AND X.colB = D.colB )=1;
Which works, and seems a little faster than my original query, so thank you for this.

Oracle 10g - undo management

Guys,
I am updating 1 million rows in Oracle 10g platform, normally when I do it in oracle 9i I run it as batch process and commit after each batch. Obviously to avoid/control undo generation. But in Oracle 10g I am told undo management is automatic and I do not need run the update as batch process.
Is this right please throw some light on this new feature - automatic undo management
Thanks

Automatic undo management was available in 9i as well, and my guess is you were probably using it there. However, I'll assume for the sake of this writing that you were using manual undo management in 9i and are now on automatic.
Automatic undo management depends upon UNDO_RETENTION, a parameter that defines how long Oracle should try to keep committed transactions in UNDO. However, this parameter is only a suggestion. You must also have an UNDO tablespace that's large enough to handle the amount of UNDO you will be generating/holding, or you will get ORA-01555: Snapshot too old, rollback segment too small errors.
You can use the UNDO advisor to find out how large this tablespace should be given a desired UNDO retention, or look online for some scripts...just google for: oracle undo size
Oracle 10g also gives you the ability to guarantee undo. This means that instead of throwing an error on SELECT statements, it guarantees your UNDO retention for consistent reads and instead errors your DML that would cause UNDO to be overwritten.
Now, for your original question...yes, it's easier for the DBA to minimize the issues of UNDO when using automatic undo management. If you set the UNDO_RETENTION high enough with a properly sized undo tablespace you shouldn't have as many issues with UNDO. How often you commit should have nothing to do with it, as long as your DBA has properly set UNDO_RETENTION and has an optimally sized UNDO tablespace. Committing more often will only result in your script taking longer, more LGWR/DBWR issues, and the "where was I" problem if there is an error (if it errors, where did it stop?).
Lastly (and true even for manual undo management), if you commit more frequently, you make it more possible for ORA-01555 errors to occur. Because your work will be scattered among more undo segments, you increase the chance that a single one may be overwritten if necessary, thus causing an ORA-01555 error for those that require it for read consistency.
It all boils down to the size of the undo tablespace and the undo retention, in the end...just as manual management boiled down to the size, amount, and usage of rollback segments. Committing frequently is a peroxide band-aid: it covers up the problem, tries to clean it, but in the end it just hurts and causes problems for otherwise healthy processes.

Transform columns in row for a table in Oracle 10g

Hi,
I am using Oracle 10g.
There is a table (example) EMPLOYEE, with following structure
IDUSER YEAR1 YEAR2 YEAR3
12345 value1 value2 value3
99999 value7 value6 value5
and I need display :
IDUSER YEAR
12345 value1
12345 value2
12345 value3
99999 value7
99999 value6
99999 value5
How can I do this with without unpivot?
Thanks

Hi,
Welcome to the forum!
One way to unpivot in any version of Orace is to cross-join your table with another table (or resut set, in ths case) that has as many rows as you need toroduce from each row of your original table.
Here's an example:
WITH     cntr     AS
     SELECT     LEVEL     AS n
     FROM     dual
     CONNECT BY     LEVEL <= 3
SELECT     e.iduser
,     CASE c.n
         WHEN 1 THEN year1
         WHEN 2 THEN year2
         WHEN 3 THEN year3
     END     AS uear
FROM         cntr      c
CROSS JOIN employee e
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only), and the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say what version of Oracle you're using (e.g. 11.2.0.2.0).

Dynamic rows to columns oracle 10g

Hi,
I'm using oracle 10g. I have a requiriement where I need to show rows to columns. I have read through many posts but I couldn't find what I wanted to solve. Lots of them are using decode, since they know the values in one column.
My table has name, value and date. I need to get values for each name at certain date (each distinct date needs to become column). I don't know the name beforehand.
Name, Value, Date
T1 100 06-27-2011 09:00:00
T2 100 06-27-2011 09:00:00
T1 200 06-27-2011 09:15:00
T2 150 06-27-2011 09:15:00
I would also need to use a date range. Someone can request date between 09:00:00 and 09:05:00 or 09:00:00 and 09:30:00 etc.
I need to print
Name, 06-27-2011 09:00:00, 06-27-2011 09:15:00
T1 100 200
T2 100 150

Oracle 10g - Defining the column name in Non English

Hi Experts,
I have an exisitng application which is developed on Windows using ASP Technology and uses Oracle 10g 10.1.0.2.0.
The application is supported with an instance of Data Base within which multiple tablespaces are created for different clients. The application is developed in such a way that some of the tables arecreated dynamically and the columns are named using the data entered through the UI.
This application needs to be globalized now. The problem is, the column name entered through the UI can be in any language based on the client's settings and those values in turn will be used for naming the columns in the tables.
1) Can I have the column names to be named using non english characters in Oracle 10g DB? If so,
1.1) what should I do to configure the exisiting Oracle instance to support it?
1.2) To what level is that configuration possible, is it per DB instance level (or) can it be done at Tablespace level. I would like to configure each tablespace to host tables with columns defined with different languages, say for example, tablespace 1 will have tables with Japaenese column names and tablespace 2 will have tables with German column names?
2) What should I do to make my entire DB to support unicode data i.e., to accept any language strings. Currently all strings are declared as VarChar2, should I change all VarChar2 to NVarChar2 (or) is there a way to retain the VarChar2 as is and make some database wide setting?
Please note that I do not have an option of retaining the column in English as per the Business Requirement.

1. Yes, you can.

1 row created.1.1 and 1.2 and 2. You can choose UTF as your default character set. It allows the user of non-English characters in VARCHAR columns in your whole database. It is not per tablespace.

Row chaining and row migration in Oracle 10g R2/11g R2

Hi,
Due to the business rule changes, one of the numeric column in a large table (20 millions rows) will be expanded from number(8) to number(10). Also, the values of this column of each row will be updated from 6 digits to 10 digits. All the indexes that use this column will be dropped and recreated after update. I would like to know if there is any row chaining or row migration issue in Oracle 10g R2 /11g R2.
Thanks for your help
