Should I use this command truncate table ...; or delete from ... where CREA_MONTH ='' or maybe other sql statement ?

Well, you may not need to worry about destroy your database but you might find out if truncate this table will destroy your application.
A truncate statement is a regular DDL of Oracle, runing it will certainly not crush your database. However you need to talk to application user to figure out if this table is really unnecessary.
Before you do the truncate, better make a backup.

Need help / Advice ; manage daily millions of records;;plz help me:)

Hi all,
I've only 2 years of experience in Oracle DBA. I need advice from Experts:)
To begin, the company I work for, decide to daily save in our Oracle database about 40 millions of records in our only table (User tables). These records should be daily imported from csv or xml feeds into one table.
This 's a project that need :
- Study the performance
- Study What is required in terms of hardware
As a leader in the market, Oracle 's the only DBMS that could support this size of data, but what's the limit of Oracle in this case? can Oracle support and manage perfectly daily 40 millions of records and for many years, ie We need all data of this table, we can't consider after a period that we don't need history: we need to save all data and without purge the history and this for many years i suppose!!! you can imagine 40 daily millions of records and for many years!!!
Then we need to consolidate from this table different views (or maybe materalized view) for each department and business inside the company, one other project that need study!
My questions 're :Using Oracle Database 10g Enterprise Edition Release 10.2.0.1.0:
1-Can Oracle support and perfectly manage daily 40 millions of records and for many years?
2-Study the performance ; which solutions, technics could I use to improve the performance of :
- Daily Loading 40 millions of records from csv or xml file/files?
- Daily Consolidate / managing different views/ materalized view from this big table?
3- What is required in terms of hardware? features / Technologies( maybe clusters...)
Hope that experts help me and advice me! thank you very much for your atention :)

1-Can Oracle support and perfectly manage daily 40 millions of records and for many years?Yes
2-Study the performance ; which solutions, technics could I use to improve >>>the performance of :Send me your email, and I can send you a Performance tuning metodology pdf.
You can see my email on my profile.
Daily Loading 40 millions of records from csv or xml file/files?DIrect Load

This is a sample code i am using in one of my programs. You can try similar way and insert into custom table with every loop pass.
I am considering 2000 records at a time. You can decide the no and code accordingly.

I reset my phone , made a new account even deleted all my apps but nothing works . How do I remove the restrictions if any for the 17+ apps ? Pleasee help !

It's set in Settings/General/Restrictions. You will need the Restrictions passcode to access the setting. Presumably someone placed the restriction on your phone. You need to talk to whomever set the restriction if it wasn't you.

How to Delete a Pattern? Plz Help.

Hello:
OS: Windows 8 64bit Photoshop CC
I made a few patterns and went to Edit > Define Pattern and named it.
Then I made a new document window and made a shape and then used the Layer Styles to try out my new pattern as an overlay.
The pattern was there which was great. (Excpet I'm uncertain of how exactly it saved).
I made some more variations of the pattern.
Now, there are a few within the set that I don't like at all and would very much like to delete them. But, everything I have tried to delete them hasn't worked out.
The oddest thing to me is that when I go to Program Files > Presets > Patterns the pattern isn't there and It's not in Program Files (x86) either.
I have tried the Preset Manager. I have tried every possible way in which one can access the patterns but nothing is working out.
When I Delete from the Layer Styles panel and then load a new set and then return to the set I made the individual patterns I want gone, and have Deleted, return every time. The Preset Manager won't seem to let me delete the pats either.
I do not want to lose the entire set just a few individual pats.
Also, I have made some new patterns which I would like to save but now when I try to save them I am told that i do not have permission to save in that location - of which is program files > presets >patters and that i need administration permission and then it asks if i want to save in: Kara which is the name of my computer. ()
(why isn't this more intuitive?)
Yes, I have read the manual ... that is what said to do it the way that's not working.
Can someone please help me? It's all driving me quite NUTS.
Thank you in advance for your time!! Much appreciated!!

hi chris
thank you for your time.
i have read what little i can find about the preset manager. i cannot find any info on how to Delete.
was just returning to say i figured out the save thing from the manual ... which oddly... is hard to find b/c when i click on Photoshop CC manual ... nothing about Patterns is listed.

HELP SET MY PASSWORD AND NOW IT WON'T RECOGNIZE. WILL DELETE ALL MY DATA PLZ HELP!!!

Hi there,
Unfortunately I made the very foolish error of setting up a password on my Blackberry this evening. I typed in (WHAT I THOUGHT) was an extremely easy password. After trying 9 times to type it in (I am on 10th of 10 tries!) I can't figure out what I typed in. I know what I thought I typed in, but apparently it's not working.
Any help here? Or am I severely screwed?
The password is three letters long. Does it usually automatically capitalize the first letter?
HELPP!!

Hi and Welcome to the Forums!
With only one attempt left, it is unlikely that we will be able to be of any help. The next time it is entered wrong, your BB will wipe itself clean of all of your data. There is no way to stop it. None. You must get the password correct on the next attempt. There's no way for us to know what password you used...so you must try to see if you can get it right. Don't do what you've already tried...you already know it does not work. Sorry, but it looks like you will be restoring from your most recent backup.
Best.

HT204150 I have 2 iphones registered under same account, but both phones had different contacts in them, somehow icloud duplicated, exchanged them. and deleted could not restore the contacts, how do I restore it? plz help

I have 2 iphones registered under same account, but both phones had different contacts in them, somehow icloud duplicated, exchanged them, and I turned off the icloud on one of them, while doing that it asked me if I want to keep them on my phone or not. I pressed the one saying not to keep them. I deleted all of them and could not restore the contacts, how do I restore it? when I sign in to my icloud account online it only shows the contacts that were on the other phone. plz help

I access a personal iPhone and iPad, and a business iPhone with the same Apple ID.
The iPhone's passcode lock feature is completely separate from another iPhone or iOS device.
All apps, all paid and free apps include DRM protection which is tied to the Apple ID that was used to download the apps. If some apps were downloaded with one Apple ID and then a new Apple ID is created, in order to download an app update that was installed with the original Apple ID requires using that Apple ID and password.

As already provided, if you don't have such in your iTunes library, on your computer, then there is no way to put it back on your phone. Apps are DRM protected, so even if you found a copy somewhere, you wouldn't be able to use it.

What's the best way to delete 2.4 million of records from table?

We are having two tables one is production one and another is temp table which data we want to insert into production table. temp table having 2.5 million of records and on the other side production table is having billions of records. the thing which we want to do just simple delete already existed records from production table and then insert the remaining records from temp to production table.
Can anyone guide what's the best way to do this?
Thanks,
Waheed.

If you really just want to insert the records and don't want to update the matching ones and you're already on 10g you could use the "DML error logging" facility of the INSERT command, which would log all failed records but succeeds for the remaining ones.
You can create a suitable exception table using the DBMS_ERRLOG.CREATE_ERROR_LOG procedure and then use the "LOG ERRORS INTO" clause of the INSERT command. Note that you can't use the "direct-path" insert mode (APPEND hint) if you expect to encounter UNIQUE CONSTRAINT violations, because this can't be logged and cause the direct-path insert to fail. Since this is a "live" table you probably don't want to use the direct-path insert anyway.
See the manuals for more information: http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_9014.htm#BGBEIACB
Sample taken from 10g manuals:
CREATE TABLE raises (emp_id NUMBER, sal NUMBER
   CONSTRAINT check_sal CHECK(sal > 8000));
EXECUTE DBMS_ERRLOG.CREATE_ERROR_LOG('raises', 'errlog');
INSERT INTO raises
   SELECT employee_id, salary*1.1 FROM employees
   WHERE commission_pct > .2
   LOG ERRORS INTO errlog ('my_bad') REJECT LIMIT 10;
SELECT ORA_ERR_MESG$, ORA_ERR_TAG$, emp_id, sal FROM errlog;
ORA_ERR_MESG$               ORA_ERR_TAG$         EMP_ID SAL
ORA-02290: check constraint my_bad               161    7700
(HR.SYS_C004266) violatedIf the number of rows in the temp table is not too large and you have a suitable index on the large table for the lookup you could also try to use a NOT EXISTS clause in the insert command:
INSERT INTO <large_table>
SELECT ...
FROM TEMP A
WHERE NOT EXISTS (
SELECT NULL
FROM <large_table> B
WHERE B.<lookup> = A.<key>
);But you need to check the execution plan, because a hash join using a full table scan on the <large_table> is probably something you want to avoid.

It depends how you installed it.
If you installed from your iLife 11 DVD, then you can insert the DVD and install it again.
If you purchased it from the Mac App Store, you can open the Mac App Store, go to the Purchases tab, and reinstall from there.
