Save as collection

Hi, we can create collection of record like below?

TYPE emp_name_rec is RECORD (firstname, lastname, hiredate employees.hire_date%TYPE, employees.last_name%TYPE employees.first_name%TYPE);

TYPE IS of Emp_tab TABLE emp_name_rec;

Collections (varray, nested table associative) must be of the same type where such as recording contains different data types.

If the record can be defined as the collection, how to fill out the collection and retrieve the records of who?

Thank you

declare

emp_name_rec subtype is USED % ROWTYPE;

TYPE IS of Emp_tab TABLE emp_name_rec;

vEmp_tab Emp_tab;

Start

Select *.

bulk collect into vEmp_tab

from EMP;

for n in vEmp_tab. First... vEmp_tab. Last

loop

dbms_output.put_line (vEmp_tab (n). LAST_NAME);

end loop;

end;

Note: emp_name_rec is not really necessary, but included to match your example.  You could just declare

TYPE Emp_tab IS the EMPLOYEE TABLE % ROWTYPE;

If you want a persistent version of Emp_tab, you must declare a type that matches the columns in the table and a collection type based on this type

create or replace type Emp_name_rec as object)

employe_id NUMBER (6)

, name VARCHAR2 (20)

, last_name VARCHAR2 (25)

, email VARCHAR2 (25)

, phone_number VARCHAR2 (20)

-etc etc.

)

/

create or replace type Emp_tab as the emp_name_rec table

/

Its use...

declare

vEmp_tab Emp_tab;

Start

Select *.

bulk collect into vEmp_tab

from EMP;

for n in vEmp_tab. First... vEmp_tab. Last

loop

dbms_output.put_line (vEmp_tab (n). LAST_NAME);

end loop;

end;

  • You can save smart collections as the regular collections.

    I want to use the photos captured in a smart collection of Lightroom in a slideshow, but I want to change the order of the slides. can I save the slides or copy them into another collection where I can do? Alternative workaround? Thank you

    You cannot change the sort order of a smart collection. However, you can select all or some of the photos in a smart collection can do a regular collection by clicking on the button at the top right of the Collections Panel +. A dialog box opens that allows you to make virtual Copies of the selected photos. This is not absolutely necessary, but it does not hurt, especially if you decide to make additional changes to the photos that will be specific to the slide show.

  • Save a collection

    trying to figure out how to save the images included in any collection.  I understand how the option is saved.

    I guess that one way would be to export the collection to my images.  another would be to use a key word to describe all images in a given collection.

    any other suggestions?

    If you have a backup of your catalog file, then you're all set... collections and everything else that you have done in LR (but not the photos themselves) are restored from a backup catalog.

    The idea of re - import your photos in the case of a failure (or in any other situation) is one, that you should avoid in the future. The appropriate method (to ensure a full backup) is to backup the catalog file and restore the catalog for the backup file.

  • Why won't save my Collections in Bridge?

    Hi, people.

    I like the idea of building collections to bridge based on keywords and whatnot.  In this way, I can have all my images in a directory and simply use to browse the collections rather than having to load each image in the directory through bridge.

    But... Bridge never seems to save collections, once I have quit the program.  The name of the collection itself, remains on a restart, but has more images in the collection.

    This is not in reference to smart collections.

  • Custom sort order - creation of new Collection

    I was reading this thread on the creation of a custom sort order - Lightroom - how do change you the order of Images, before you rename? Blog of "Julieanne Kost .

    I work with a collection that contains subfolders, so I selected all the images, then tried to create a new collection. But when I click on the file, I see a choice for a new catalog, but not a 'new Collection '. There is a choice to "save quick Collection.» But when I choose that option, I get an empty folder with the name I have given.

    So, how to create a collection?

    P.S. I noticed I have a lot of empty folders. Is this OK to delete all the? I imported a folder full of subfolders of images, and I'm guessing that subfolders are imported, but the images have been taken out of them.

    Thank you.

  • Download explicit Collections

    Hello

    Read what's new page (Digital Publishing Solution help |) What's new in this version of DPS 2015) I see that a collection can be downloaded only mode of navigation page... right now:

    A user can download a collection, the following conditions are required:

    • The option 'Allow the user to save the collection of their device' (new) must be enabled in the properties of the collection.
    • The user must have access to the collection.
    • The collection must be downloaded from a navigation page. If a collection is set to content rather than navigate to Page, it cannot be downloaded to at this time.

    This means that this option could be implemented later in the collections of content display Mode? (witch will be really more user-friendly)

    We plan to add the possibility of invoking a download of the map collection of the collection. It would be control to have downloaded a collection that opens to the content view. We are still working on the designs on this issue, because it has an impact on how the cards appear on the page go.

    And is it possible to open the same collection in other Adobe programs.

    For example: I'm on the collection in the sections called "Leon" in Illustrator. Is that what I can then open the same collection "Leon" in InDesign for example?

    Set up the nuances that you want set in a document by default and save and close all files. Open the Swatches palette pop-up menu, choose Load swatches, go to the doc with the default set and load them. They should now appear by default in all new files.

    When the I go back to demand 100, I see that there is no such thing as the collection I had earlier.

    Is there a way I can save this collection.

    No, we don't see using standard view APEX i.e. apex_collections. apex_collections is nothing else than a view of database tables apex integrated as the wwv_flow mark

    To understand it better check the view apex_collections view definition if you have access to the schema of the APEX.

    You might be able to create a custom view based on the built-in sql to view apex_collections, omitting the where clause that restricts the APPID.

  • Searching within a collection?

    I work with a massive library of images, over 15,000 images are in. It is located on a server at work and is very slow to load whenever I need to find a picture.

    Yesterday, I realized I could save a collection, so I did. This makes it much faster to load the images. However, I now need to look in the pictures. I load the collection, research, type 'Beach' and he told me that he has nothing to do with the word "beach" in it on my desk. I don't want to get my office - I want to search my collection. How to make this work?

    It seems that you cannot search collections, but it can be done with a script, as for example the following script will create a new collection of the search criteria.

    Copy and paste the script in ExtendScript Toolkit

    Starting point

    Edit - Preferences - Startup Scripts

    Click the button to "Reveal" to open the folder where the script should be saved.

  • The target Collection problem... Help

    Hello

    Last night, I put one of my collections as a "Collection of target.  I clicked on the target folder and choose "Set as target Collection."  When I sent a group of images to the Collection target, however, they finished in a quick Collection folder is the heading catalogs.  Not sure how this folder to the quick Collection got there.  I then re-highlighted the collection I wanted to give in as the target Collection.  The "set as target Collection" invited did not appear in the dialog box when I right click on it.  I went up to the file tab and went down to "Set as target Collection."  It is grey and not worked.  Quick Collection under catalog has the sign (+) next to indicate that it is the current target Collection.  I can't delete this quick Collection or change the target Collection.  It is gray on the file tab and does not appear in a folder.

    I rebooted the computer several times and I have "revived and optimized."  Nothing has changed.  When I right click on the mysterious quick Collection, my only choice is to delete or save quick Collection.  All ideas are welcome.  Thanks in advance.

    I clicked on the target folder and choose "Set as target Collection."

    So it's a folder, a collection or a collection of smart? Or maybe a set of collection?

    Yo can only set static collections as Collections of the target.

  • Collections, I need some clarification

    I understand the difference between Collections and folders and realize that the Collections are "virtual folders"; However, I want to clarify the

    difference between:



    Quick collection-


    Collection


    If these two types of Collections are virtual folders and not a copy of all the images, just a pointers to each time the images are located. So, what is the difference between the two?


    I also realized that I can save quick Collection in a Permanent Collection, then what good making a two-step process?


    Smart Collection - is this similar to the use of filters to select specific images with specific criteria using keywords etc.?

    I also realized that I can save quick Collection in a Permanent Collection, then what good making a two-step process?

    Because sometimes you need these combined images just for some reason any momentary and will never need in the future. I often use the quick collection as a unique temporary collection that is simply thrown away after use.

    Smart Collection - is this similar to the use of filters to select specific images with specific criteria using keywords etc.?

    Yes and no. Filter affect the current display only, a folder, a collection of collection/chip or a combination of all. Smart collections are still working on the entire library. It is convenient to use SCs as some sort of more permanent filters and filter library as a temporary quick.

  • New laptop a brick?

    I bought a HP Envy 15-q210TX on 8 August 2015 and spashed kid last week a friend a little juice of the Cup who landed on the keyboard before I could take a towel, my laptop turns off suddenly and I couldn't feed him since.

    After calling the store I bought it at and HP support, repair it will cost $1543,09, which is more that I bought it for.  I again using my child of 5 years old but still usable Sony Vaio.

    I swear there's a sign upward on HPs SG 50 promotions, one of them, including an extended warranty with included accident coverage at the time.  Yes, I went to a place of redemption in the Orchard Central and she bought after you bought the laptop.  Nobody seems to know what I'm talking about.  I also never got my free T-shirt of 50 SG either even if I went to the website, www.hp.com.sg/window10 to save and collect, but that's another story.

    Did I just spend $1400 for a brick?  Someone at - it suggestions on what I can do use?  I'm really really sad feeling about it now, because I paid for a subscription to Norton that was already loaded on your laptop and you import things on it like my completed tax forms.

    Seems the service and support is a bit different to Singapore.  In the United States for comparison, I could have gone to any Costco and exchanged for a new laptop, no questions asked.   Everyone I spoke so far, does not seem to be compassionate about my situation and were not able to guide me on what other options there except to pay the exorbitant amount for repair.   I hope someone HP reads these forums and can do something about it.

    Thanks for any help or advice you can give.
