DBMS_CDC find only the columns that are changed along with the primary key in the table
Hello,
We are having a requirement to find the change data in the production environment.
We are planning to use the DBMS_CDC utility.
But for example in the create change table 1 picked emp_id,ename, address, salary,dob.
I have a sample data of
empid
ename
address
salary
DOB
1
test1
24 test street
2000
20-Jan-98
2
test2
25 test street
2500
15-Aug-97
if ename for empid 1 is changed to test1_test3 from test1.
My CDC is capturing the values in the old and new values in the 5 columns.
But i need to get only the empid (primary key of the source table) and the ename column as only that's been updated not the rest of the 3 columns.
Can i accomplish this.
Please advice.
Hello,
Thanks for the information.
but if i change the change table then i will miss the other columns right?
I want to get the columns( empid and ename) only if ename is changed. i.e when ever any column in emp table changes i need to get all the columns where the data is changed along with the primary key columns empid.
Is there any way i can tweak the parameters so that i can achieve this or is there any other way using the cdc i can get this data.
Thanks

Are the fonts that are available to me when I am using the free trial of InDesign less than when I use the purchased version of InDesign?
Try to find out: When you install the Creative Cloud Desktop app, Click Assets, then click Fonts. Click Add Fonts from Typekit. If you can do that, you're in. Of course, you won't be able to use them more than 30 days unless you subscribe. (But fonts embedded in a PDF or EPUB file would be fine.)
Those of us who are CC subscribers cannot test this out easily. -
My old iphone backup date of 1/15/12 on itunes seems out of date. I just synced it before I am going to initiate my new iphone 5 from the Mac that I just synced with. Will it pull the recently synced info or the 1/15/12 data?
Let me see if I've gotten this right! You want to remove an account from BOTH machines? Do this for your new machine first, then for the other.
Click the Apple logo on the top left of the screen, System Preferences, Users and Groups (under Systems), unlock the lock in the window if its locked (you need to know the password), select the user that you wish to remove, and click the - sign next to the + sign for Login options. A window will pop up with some options. Select Delete this user and securely, and click 'Delete user'.
After this, do an update from the App Store.
Thats all there is to it.
For the other machine repeat the process except for one thing. Before you delete the user in this case YOU, you will have to give Administrator priviledges to your son bu checking the box 'Allow user to administer this computer'.
Do NOT do anything from Finder ... if you dont know how to fix the consequences of the problems caused.
There is no need to unauthorize your iTunes account on your new machine. Do it on the old machine though. -
Tracking the name of the column that is changed
hi
How i can track the following information about a table
say i hve the table name tab1 which is like this
col1 col2
1 2
Now if i change the value of col1 by a trigger i can track the change value but how can i track the name of the column
say in the table tab2 i am tracking the result
changed_col_name changed_val prev_val
now changed val and prevval can be tracked by trigger but in the column changed_col_name how i can track the name of the column which i changed?
Thanx in advanceYou are being rather unclear here.
If you change the name of a column your trigger will need to be amended. I don't think you're actually asking to track changing actual column names.
What you require is to track value changes and want to know how to assign which value to which column.
each value is associated with a column, therefore if you track that the 5th value in your value clause has changed that means that the column that is affected is the 5th column in your column list.
A simple if block would do the trick.
But probably a better suggestion is to store the rows in a history table.
Each time theres a change insert into the history table (which has its key column based on a sequence or a timestamp)
Then to see whats changed you can merely compare the current row to the previous row -
What is the best way to drop and recreate a Primary Key in the Replication Table?
I have a requirement to drop and recreate a primary key in a table which is part of Transaction replication. What is the best way to fo it other than remove it from replication and add again?
Thanks
SwapnaHi Swapna,
Unfortunately you cannot drop columns used in a primary key from articles in transactional replication. This is covered in
Make Schema Changes on Publication Databases:
You cannot drop columns used in a primary key from articles in transactional publications, because they are used by replication.
You will need to drop the article from the publication, drop and recreate the primary key, and add the article back into the publication.
To avoid having to send a snapshot down to the subscriber(s), you could specify the option 'replication support only' for the subscription. This would require the primary key be modified at the subscriber as well prior to adding the article back in
and should be done during a maintenance window when no activity is occurring on the published tables.
I suggest testing this out in your test environment first, prior to deploying to production.

Against my better judgement, I updated my Itunes software when I got my wife a new Iphone. Problem is, instead of my old playlists, I can only view a few "Smart Playlists". In addition, what songs are in them include a bunch of my daughter's music, which isn't even stored in this computer. So it would seem that somehow my itunes is screwed up somehow. Does anybody know how to get rid of this "Smart Playlist" crap and get me in touch with my old library and playlists?
See this post.

When iWorks for iCloud Beta become available I subscribed to it. After that I become unable to access iCloud at all as in all my devices I get messages to install it and other apps (find my phone, etc) that are already active. Anyone could help?
The first time an iPhone is connected to iTunes that is used to sync with another iPhone or iOS device, you are prompted to transfer the backup for the other iPhone or iOS device or to set up the iPhone as a new iPhone.
The former does as provided - it transfers the backup for the other iPhone or iOS device to the iPhone replacing all data on the iPhone that is included with the backup being transferred. The latter does nothing allowing you to make your various selections for the iPhone sync preferences with iTunes.
This is designed to be done right away with a new iPhone.
If you don't have a backup for the iPhone with iTunes on your computer and don't have an iCloud backup that hasn't been updated since choosing to transfer the backup for your iPod Touch to the iPhone, the data that was on the iPhone is gone. -
Join 2 tables which are not related with any primary-foriegn key constraint
Hello,
How to join 2 tables which are not related with any primary key foreign key constraint.
Ex.Consider Table A has 5 columns->A_ID,A_Name,A_Address,A_City,A_Pin(Total 10 rows)
Table B has 5 columns->B_ID,B_Name,B_Adress,B_City,B_City(Total 30 rows)
From both the table i want the data,which i need to use in curosr to display finally as "Address Label".
Both the table are entirely different,but there can be some names of Table A which may come in Table B also,if the name,address and city is also same.That means same person in both the table.
So finally i want total number of distinct records(distinct data of Table A which is not in B+all the data of table B) to come under Address Label.
How can i write the select query for this condition?
Thanks

Both the table are entirely different,but there can be some names of Table A which may come in Table B also,if the name,address and city is also same.That means same person in both the table.I think you want a UNION, not a join.
If you have 10 rows in table_a, and 30 rows in table_b, then
SELECT A_ID, A_Name, A_Address, A_City, A_Pin
FROM table_a
UNION
SELECT B_ID, B_Name, B_Adress, B_City, B_City
FROM table_b
ORDER BY 2, 4
;will produce up to 40 rows; 40 if there are no duplicates. (UNION implies DISTINCT.)
The corresponding column types should be similar, if not exactly the same.
There's no problem if A_Name is VARCHAR2 (50) and B_Name is CHAR (30).
However, there will be a problem if A_ID is a NUMBER and B_ID is a TIMESTAMP.
You must have the same number of columns in all branches of the UNION.
If you want an ORDER BY clause, put it at the very end, after the last branch of the UNION.
You can use positional notation (where 2 means the 2nd column) like I did, or you can use names from the first prong of the UNION (such as A_Name).
From both the table i want the data,which i need to use in curosr to display finally as "Address Label".
So finally i want total number of distinct records(distinct data of Table A which is not in B+all the data of table B) to come under Address Label.I'm not sure what your mean about "Address Label".
Whenever you have a question, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables, and the exact results (formatted) that you want from that data.
You can concatenate all 5 columns into one VARCHAR2 column, if you want to.
You'll probably want to use RPAD (or simillar functions) to make the output line up nicely.
If any of the columns are not strings, use TO_CHAR to make string versions of them.
For example:
SELECT TO_CHAR (A_ID, '9999999')
|| ' ' -- leave a little space between the left-justified a_id and the right-justified a_name
|| RPAD (A_Name, 25)
|| RPAD (A_Address, 50)

How do you change the fields that are displayed on the email preview list after a search?
How do you modify the fields that are displayed in the mail preview list in the center column of Mac mail after you conduct a search of your email? All of a sudden the displayed fields changed on me whenever I do a search in mail. When I have not filtered my email with a search, the default field shown in bold at the top of each message's preview is the "From" field. However, when I do a search this changes to the "To" field. Can anyone help? Thanks, ccarey

But why would you want this?
iTunes is responsible for the File Management, let it get on with it, you do your organisation in the iTunes window. And everything you need to do, you can do via the iTunes Window. Want to find the file of a track quickly? Right click on it in the iTunes Window and select Show File: A finder window pops open with the file already selected.

My iMac holds my main iTunes account and it shows 4 devices are authorized to play iTunes. I can only name 3. How do I find out a list of all the devices that are authorized from this computer?
I don't believe this is possible, but you can deauthorize all your computers and start over if you are concerned.

how do you see the items that are backed up to iCloud - I have 4.5 GB that I have used but I cant find where to see those items...help
That is everything in your iCloud account. Videos and camera roll photos are only included in your backup, the size and content of which you can see on your phone in Settings>iCloud>Storage & Backup>Manage Storage>tap the name of your device under Backup. This will show you the size of "Camera Roll", where these are contained. (You can't see any detail beyond that.) Photo stream photos can only been seen in your photo stream album on your phone, and they don't count against your storage so they aren't part of the 4.5 GB. Everything esle is either in the backup, the items listed in Settings>iCloud>Storage & Backup>Manage Storage, or on icloud.com, where you can see your contacts, calendars, etc.

Can you please CLEAN up the podcasts that are no longer in service or being maintained? It's very tedious to click on someone's podcast to find that it hasn't been updated in 3 years.
This is a user forum and it is best to post these inquiries to Apple Feedback:
http://www.apple.com/feedback/
You are right, a lot of older dead podcasts do not belong in the podcasts section. But there is still a lot of these podcasts that have good information and deserve to still be listed. For example there is quite a few photography lesson based podcasts in which you can get good information from different sources. -
I have several pdfs on my iPad in iBooks. My iPhone shows only the categories, none of the documents. How can I get my iPhone to also show the documents that are on my iPad?
You will need to connect your iPad to your computer's iTunes and do File > Devices > Transfer Purchases to copy them over to your computer (that will copy PDFs and epubs that are in the iBooks app, not just actual ibooks), and you can then sync them to your iPhone. Or you might be able to open each PDF in iBooks on your iPad and use the share icon to email them to yourself and then use 'open in' in the Mail app on your iPhone to copy them to its iBooks app (if the PDF is protected then you may not get the email option via the share icon).
The Settings > iBooks > Sync Collections setting doesn't copy items between devices, it just means that it a bookor PDF is on both devices and you move it into a collection on one device then it will be moved into the same collection on the other device
