How To Add Sequence Column To Existing Table With Records
Dec 8, 2012I had created a new table named USERLOG with two fields from a previous VIEW. The table already consist of about 9000 records. The two fields taken from the VIEW, i.e. weblog_views consist of IP (consists of IP address), and WEB_LINK (consists of URL). This is the code I used,
CREATE TABLE USERLOG
AS
SELECT C_IP, WEB_LINK FROM weblog_views;
I want to add another column to this table called the USER_ID, which would consists of a sequence starting with 1 to 9000 records to create a unique id for each existing rows. I'm using Oracle SQL Developer: ODMiner version 3.0.04. I tried using the AUTO-INCREMENT option,
ALTER TABLE USERLOG
ADD USER_ID INT UNSIGNED NOT NULL AUTO_INCREMENT;
But I get an error with this,
Error report:
SQL Error: ORA-01735: invalid ALTER TABLE option
01735. 00000 - "invalid ALTER TABLE option"

SQL & PL/SQL :: Pivot Table Using UNIX Timestamp
Feb 23, 2010I am trying to produce results in pivot format. I want to know how many entries per day per month. In other words how many entries on a Monday for each month, how many on a Tuesday for each month and so on.
The main problem I have is that the date column in the database uses UNIX time stamp. I have managed to get the results I want for a particular month. This code selects the entries for last month.
select
max(decode(pdayno, 1, cnt, null)) Sunday,
max(decode(pdayno, 2, cnt, null)) Monday,
max(decode(pdayno, 3, cnt, null)) Tuesday,
max(decode(pdayno, 4, cnt, null)) Wednesday,
[code].......
This code produces the result:
What I need is for another column at the start of the results to give the month so I end up with 12 rows, 1 for each month.
I did try to group by PENTERED(which is the unix time stamp column)
select pentered,
max(decode(pdayno, 1, cnt, null)) Sunday,
max(decode(pdayno, 2, cnt, null)) Monday,
max(decode(pdayno, 3, cnt, null)) Tuesday,
max(decode(pdayno, 4, cnt, null)) Wednesday,
[code]......
This gave me thousands of rows as each UNIX time stamp is unique. Is there a way of grouping on UNIX time stamp.

Replication :: Timestamp For A Table For Conflict Resolution
Aug 25, 2008I have a question about the timestamp conflict resolution. let me describe my question with making an example:
I have a table(test1) with 3 columns(a,b,c)
I do also have 3 column groups one for a ,one for b and one for c if i want to use timestamp conflict resolution for b and c should I add 2 column timpstamp1 and stimestamp2 to test1 for each of these columns and define 1 trigger for each of them?
I hesitated because if it is true and for example if we have lots of columns which need timestamp conflict resolution the size of our table become very big.Is it correct?

SQL & PL/SQL :: Oracle 10g - Update Records In Target Table Based On Records Coming In From Source
Jun 1, 2010I am trying to update records in the target table based on the records coming in from source. For instance, if the incoming record is present in the target table I would update them in the target else I would simply insert. I have over one million records in my source while my target has 46 million records. The target table is partitioned based on calendar key. I implement this whole logic using Informatica. Looking at the informatica session log I find that the informatica code is perfectly fine but its in the update part it takes long time (more than 5 days to update one million records). find the TARGET TABLE query and the UPDATE query as below.
TARGET TABLE:
CREATE TABLE OPERATIONS.DENIAL_REGRET_FACT

CALENDAR_KEY INTEGER NOT NULL,
DAY_TIME_KEY INTEGER NOT NULL,
SITE_KEY NUMBER NOT NULL,

Partitioning - Switch Partition Key On Existing Table?
Jan 23, 2011I recently started working with legacy code and noticed that some huge tables (5 years worth of data, don't have more details on me right now but can post later if needed) are partitioned based on time sequence number column while majority of queries are done based on time (different column). Queries performance is degrading and I'd like to try to modify partitioning and run some tests to evaluate performance improvement.
My only concern is with so much live data I have to come up with solution on how to switch partitioning with the least impact on applications running 24 x 7. Something you have done in the same situation and it worked?
