How can I create index in a view?

Dear all,
How can I create index in a view?
Best Regards,
Amy

A view is a stored query. It gets executed at run time. A view does not occupy any physical space in the database (other than the insignificant amount of space required to store the query in the data dictionary).
A materialized view actually materializes the results of a query in a separate table structure, so it consumes physical space in the database. It also has to be refreshed at some interval, either synchronously with DML or asynchronously on a set interval.

How can I create a full-screen view of Keynote slide in Snow Leopard?

How can I create a full-screen view of my Keynote slides in Snow Leopard?
I'm going to be importing into ScreenFlow to create a video.
Thank you!!

Welcome to Apple Support Communities.
Do you want static screen captures or motion video of slides as titles, bullet points, and the like are presented?
Run the Keynote slide presentation in full-screen mode, then...
Static full-screen captures - use Command+Shift+3.
Static partial-screen captures - use Command+Shift+4 and use cursor to select the area of the screen to capture.
If you want motion video as builds occur, why not use Keynote's built-in Share, Export function?
(I'm on iLife '09.)
Also understand that the default slide format for Keynote is 1024x768, not full-screen MacBook 1280x800 screen size, so you'll have wide black borders unless you change the default size or crop the finished screen captures.

How can I create index(uniqie index) for a existed table?

Hi guys,
I want to create a index for a existed table, it should be unique index. I did it using se11, "indexes," and select the radio button "unqiue index", of course the fields as well. But when I activate it, I get a waring and therefore can not create this index. But if I select radio button "non-uniqe index", it works.
However I have to reate a unqiue index.
How can I do it?
Thanks in advance
Regards,
Liying

HI Wang
You can create your index via SE11, enter the table name, click change, choose Go To, Indexes. Here create your index with the key fields that you want. To use the index, your select statement WHERE clause, you must have the key fields of the index in the order that they appear in the index. The "optimizer" will choose the index depending on your fields of the WHERE clause.
One thing to remember is that when you create indexes for tables, the update or insert of these tables may have a slower response then before, I for one have never seen a big problem as of yet.

Can I create index on Materialized view log

Hello
The ADDM suggest me to create index on some fields of my materialized view log , I don't know does it cause any problem ? Is it safe ? have you done it before ?
thanks

Actually you can do it since materialized view log is in fact a table.
SQL> create table t(x int primary key);
Table created.
SQL> create materialized view log on t;
Materialized view log created.
SQL> select segment_name, segment_type from user_segments;
SEGMENT_NAME
SEGMENT_TYPE
MLOG$_T
TABLE
T
TABLE
SYS_C004857
INDEX
SQL> desc mlog$_t;
Name                                      Null?    Type
X                                                  NUMBER
SNAPTIME$$                                         DATE
DMLTYPE$$                                          VARCHAR2(1)
OLD_NEW$$                                          VARCHAR2(1)
CHANGE_VECTOR$$                                    RAW(255)
SQL> create index i on mlog$_t(x);
Index created.However I don't know if this is really supported and makes sense.

How can I view my photos in "Events" like in iPhoto? How can I create events? I have 55,000 photos and 1700 events so the only way I can possibly manage my photos is using events that are one slide in size.

I have 55,000 images organized into about 1700 events. The only reasonable way to view my library is using events in iPhoto where each event has one image That still leaves 1700 images to sort through but that is a lot easier than 55,000 images. In the side bar is a folder with "iPhoto Events" but those views still show all of the slides. How can I create events and view my photos as events as in iPhoto? Events are critical for large libraries and has been my primary way to sort images.
Thanks!

I had a problem a couple of months ago when iPhotos suddenly rearranged the order of my Events (Why won't iPhoto let me arrange my photos?) . I was told "Use albums not events - events are not a good way to organize - albums and folder are designed for organisation and are very flexible".
Haha! I should have paid attention and read between the lines! My iPhotos were highly organised groupings - not according to date but the way I wanted them - and it was so easy to do! I see now that if I had them all in albums, as per the Apple Apologist suggestion, I wouldn't have this unholy mess I have been left with just to make iPhone & iCloud users happy. I am now going through Photos and making Albums (of what used to be in my Events) ... maybe I'll get this finished before they do another non user friendly update!

How can I create a URL for a PWA for MS Project Server 2010 project file that includes the view?

Hi, this question has been answered for 2013. The answer here suggests that it can be done in 2010.
See:
http://social.technet.microsoft.com/Forums/projectserver/en-US/3affdc4f-36bf-4381-8b75-27c73465efd4/action?threadDisplayName=how-can-i-create-a-url-for-a-pwa-for-ms-project-server-2013-project-file-that-includes-the-view
Who knows how?

Hi Sander,
As far as I tested it, it is not possible either with PS2010. The URL only contains the PDP name and the projUID.
Hope this helps,

How can I create an index on the date part of a timestamp field?

is there a way I can create an index on the date part of a timestamp field?

LONGENECKER wrote:
Idea:
If you find no direct command that allows you to create an index on JUST the date portion of a timestamp datatype column then I recommend you consider splitting date and time into two seperate columns.
If date is column "A" and time is column "B" then you can concatenate them using a view or virtual column (in 11G) to re-assemble them at run time.
In the solution I describe above you might trade ease of management for better performing queries.
Additional Info:
This thread may be of some value.
Can we create INDEX on TIMESTAMP column???
And what datatype do you propose for your columns A and B? The only proper datatypes would be DATE or TIMESTAMP. Both of these inherently carry both date and time components, so that would have to be dealt with anyway. The use of any character or number datatype to hold date and/or time should be treated with an application of Billy's lead pipe.
Perhaps function based indexes would be a better solution.

How can I pass field value betwen view in ICWC?

Hi experts,
I am new to this BSP programming. I have some requirements to modify standard ICWC in CRM 5.0
Hope can get some advices and helps here.
I have added a new field called <status> to context note SEARCHCUSTOMER in BupaSearchB2B view and also the same field name to context note CUSTOMER in BupaCreate view.
I have added the field into both the HTM views and able to execute thru WebClient. However, I have one problem in passing the <status> value from BupaSearchB2B view to the BupaCreate view when I click on the 'create' button.
I do search and saw this thread How can I pass field value beetwen view in IC Web Client? , but i cant figure out how it works.
Do I need to create the field <status> to context note CUSTOMER in BupaSearchB2B? Currently the context note does not have any attributes.
Really appreciate for any help.

How can I create an EntityStore for a Database? Advice on DB strategy?

Hello All,
How can I create an com.sleepycat.persist.EntityStore for a com.sleepycat.db.Database? Advice on DB strategy?
I'm looking to create an application prototype that creates a database dynamically and can delete it programatically. Is openDatabase/removeDatabase what I'd want to use for that?
So far, the Direct Persistence Layer is an amazing piece of technology and has the potential to make my team's application faster than we every though possible, so kudos to the author.
I've built a high-security application using the DPL and a single database for hundreds millions of users. I'd like to attempt to create a database for each user for security and manageability purposes. Our mission statement doesn't allow us to execute queries for sensitive data across more than one user account at a time, so I don't get any benefit from having every user's objects in a single database. I'm investigating if giving each user their own database will speed up insert times and SecondaryIndex queries. It'll certainly be more secure as each database will be encrypted with a unique password.
My design is that I have an app with dozens of com.sleepycat.persist.model.Entity beans which I persist and query on their Primary and secondary indexes. I've been accessing things through an EntityStore as illustrated in the Getting Started Guide. Can I access a database created with openDatabase through an EntityStore and com.sleepycat.persist.PrimaryIndex?
Thanks in Advance,

How can I create a new recovery key if you automatically removed my trusted device after update do iOS 8?

How can I create a new recovery key if you automatically removed my trusted device after update do iOS 8?

Hey -
I need to do the EXACT same thing, but have no idea how. Has anyone out there done this?
My situation is a tad different..this is a new Mac (and I'm a brand new Mac user). Tons of querks occur under my original account (videos won't run, Safari won't support certain plug-ins). I spent 6 hours on the phone w/ 4 different Apple Reps and nobody could fix it. A rep finally looked at my MacBook Pro in person today. He created a new account just to see if that would work and under that new account, everything works perfectly fine (no querks, can view video). He tried switching a million settings in my original account to no avail.
He said to create a new account (as he did) and move my files over to the new account and then go back to the original and delete it. How do you do this?! I can't figure it out! I've got a new account created, but of course it just has the default folders in it w/ the little red icons next to them! Thanks in advance!
