  Hello
  
  We need to export some tables and are looking for a guide on the sapce used by the table and associated indexes.

  It is the best way to get idea of psace used by an indivifula and index tbal or is there a better way?
  
  Thank you

  below expdp command gives you the size of the tables you want to export, it gives you only the size but never exports.

  expdp user/pwd@db tables = a, b = y estimate_only

  You can also try

  SELECT SUM (bytes) / 1024/1024 MB OF dba_segments WHERE segment_type = 'TABLE' AND owner = 'USER' AND nom_segment = 'TABLE ';

• What is the best way to copy a large poster and print it?

  I am doing a project of great art (about 5 feet by 5 ft), where I'm going to learn things by hand and would like to make a copy of this project by analysing the it in the computer, or to take pictures high resolution project and their compilation together in the computer and then print the image at this size, or larger. So, I'll have the original, 5x5ft and one printed copy.

  I heard that vector images are ideal for this, so is recommended for Illustrator this?

  I know it is a vector graphics program, but is it possible that I can take a bitmap of a scan or photo and somehow become a vector? If this is not possible, what are the recommendations would you?

  I have Illustrator CS2.

  I do not believe that the scanners large format are flat, if I'm wrong. In my view, they have a mobile head that scans the original bottle then made up the data with the software.

  It is not cheap, if the original can be easily damage they'll probably damage it unless you make sure that beforehand what they know about it
  and that they accept that they can scan without damaging it.

  Photography is a good solution if you know how the art of light and you use a long distance goal.

  The reason is shooting with a normal or wide-angle will give an effect of stretching the edges especially bandwidth due to the proximity of the camera to subject distance. The lens and the longer distance will accomplish the same capture without you stretching effect.

  Now, if you really have a service experience work fine arts or large commercial then scanning might be the way of.

  In both cases, I don't think you want to vectorize the art.

• best way to avoid the full table scan for clause "column is zero.

  I have a query with is control null, and because of that it performs a total scan of table (in millions of rows in the table)
  
  SELECT id, x,
  LAG (id) OVER (PARTITION BY userid ORDER BY has had place, id) as p_id,.
  FROM MyTable
  WHERE X is ZERO
  
  
  What is the best way for me to avoid the full table scan. I have indexes for the X column and other columns.
  
  Thank you

  Hi Vasif

  NULL values are indexed if the indexed entry also includes a value non-zero.

  If you create an index such as:

  CREATE INDEX mytable_x_idx ON mytable (x, ' ');

  ensure all null values for the column X are indexed and will therefore potentially use the index to search for null values, assuming of course the result set is small enough to justify the use of the index in your query.

  I have spoken previously on my blog:

  It should be possible to insert tens of thousands of lines in a few seconds using an insert even with a complex query as the view object and validation at the end.

  Maybe that's where you're going wrong, records are to put on the turntables.

• URGENT! Best way to send a large project FCPX to another editor?

  Hello

  I worked remotely on a FCPX project for a client, and now it's time to transfer so that another editor can finish editing.

  We both have the same files source on our drives.

  As I began the project my end, I have the library FCPX here with the timelines for project I want to send him via Dropbox, BUT that the total library file is 768 GB! I am able to send ONLY the timelines for project? It will be capable of to re-connect media easily its end?

  What is the best way to achieve this?

  Help, please!

  Thank you.

  You may not use the managed media when you are working. Assign an external location for your media in the library properties. Consolidate the library for media are moved out of it. Create a library of transfer where you copy the items you want to share with the other editor. Send it to them. They have a record that must match yours with the media. They reissue the multimedia content.

  Looks like an elastic layout. Experiment with Cntl + /. Also perhaps that some experts here can tell us how to get the Cntl + / return to "neutral".

• Best way to reduce the captured elements?

  Sorry if this has been asked a thousand times, but I do not see in the FAQ.

  I have a Canon Vixia camcorder HD capture and stored in the AVCHD format, once I drag video clips on my computer. They look great on an Apple Cinema Display 30 "monitor.

  I'm looking for the best way to go through the video clips of my guardian and cut each end of the segment to get rid of unnecessary images and now the part of the clip I think that I would ever use. In fact, I know how to cut the picture, I'm looking for better work flow through a lot of long clips and cut down and save for long-term storage without losing any quality of image.

  If I have registered 100 clips that can each be shortened, what is the best workflow in first Elements 8? That format and output settings would be best?

  Original Canon files were saved with extensions MTS on a PC. My few tests registered tonight shortened as M2T files. In the initial run through, they seem to have the same image on my screen quality.

  Any help would be appreciated.

  Mr. Jackson

  Yes, you can load all the clips in the same project and then prune one at a time on the timeline, M.

  In fact, it is probably the best solution!

  If you are using project settings appropriate for your source footage, share your built in 1440 x 1080 MPEGs video should give you virtually no change in video quality. Certainly nothing notable.

  You will then be able to load these video clips in a project implemented for HDV video formats and they should work great!

• What is the best way to manage a large image with many tiny objects?

  The photo in question is a mosaic composed of thousands of small shapes in Illustrator. It's about 28 in. x 48 in, but there is a white space around the image. I'm less than a quarter of the way through, and I notice that the AI starts to be slow during the refresh of the screen for example when changing the zoom. The file is 13MB. I fear that the image is too big to have to effectively manage. Would you advise me to break down the image into quarters and put them together at the end, or do you think I will deal with the scale and complexity effectively? If I have to separate section, there's a useful technique to use for this? Thanks in advance.

  You should not cut the image to make your application more efficient.  If it is intended for large format, you can reduce the resolution of the image of what is appropriate for the output device.  If it is a project of offset press, a picture that size is still manageable.  13 MB, I have a feeling that something is causing the slowdown.  You have a disk of assigned preference work?

• best way to control a large number of controls and indicators

  IM building a façade with 46 orders and lights, all of type boolean.

  the logic is control > send order series > receive > indicator set. I consider part of my façade (with 2 sets of control and indicator) and my block diagram.

  I have to be able to control programmatically and through the front panel individually the status and indicators, or all at once (for example to reset the both). This should be done from the tab they are and another.

  thought property nodes but still I would have 46 + 46 of them. same for local variables.

  y at - there I way to refer to a control/indicator by its label (string) and change its value?

  wouldn't be easier just to create two Boolean tables which maintain their Boolean value?

  Please advise me on what options I have. I'm new to labview.

  Thanks in advance.

  
  

• Best way to split the large partition to few smaller

  Hello

  I have Oracle 11.2 EE on Redhat 5.9 and I need to solve the problem with partitioning.

  A few tables of some system has been prepared for partitioning a few years ago. But no partitioning was done and all these tables / global index have only one partition for all data.

  Now, we have a lot of tables and indexes with a single partition (with limit MAXVALUE) for all data. I would like to divide this large partition to smaller partitions more by quarter of the year.

  Example:

  Existing partition that d0201_2008_1q must be split at D0201_2008_2Q, D0201_2008_3Q... MYTABLE_2014_4Q of column DATE/NUMBER

  I tried to generate a script for sharing partitions

  ALTER INDEX I_D0201 CHANGE DEFAULT TABLESPACE INDX_2008_1Q ATTRIBUTES;

  ALTER TABLE SPLIT PARTITION D0201_2008_1Q AT (1000456) D0201

  INTO (PARTITION D0201_2008_XX TABLESPACE DATA_2008_1Q, PARTITION D0201_MAX1) 16 PARALLELS;

  ALTER TABLE D0201 CHANGE THE D0201_2008_XX REBUILD UNUSABLE LOCAL INDEX PARTITION;

  ALTER INDEX I_D0201 CHANGE DEFAULT TABLESPACE INDX_2008_2Q ATTRIBUTES;

  ALTER TABLE SPLIT PARTITION D0201_MAX1 AT (1000547) D0201

  INTO (PARTITION D0201_2008_2Q TABLESPACE DATA_2008_2Q, PARTITION D0201_MAX2) 16 PARALLELS;

  ALTER TABLE D0201 CHANGE THE D0201_2008_2Q REBUILD UNUSABLE LOCAL INDEX PARTITION;

  ALTER INDEX I_D0201 CHANGE DEFAULT TABLESPACE INDX_2008_3Q ATTRIBUTES;

  ALTER TABLE SPLIT PARTITION D0201_MAX2 AT (1000639) D0201

  INTO (PARTITION D0201_2008_3Q TABLESPACE DATA_2008_3Q, PARTITION D0201_MAX3) 16 PARALLELS;

  ALTER TABLE D0201 CHANGE THE D0201_2008_3Q REBUILD UNUSABLE LOCAL INDEX PARTITION;

  ...

  It separates great score to two new partitions. One of them is the next quarter and secondly will separate again.

  Some partitions have a few GB and splitting takes a long time (hours for a split partition) and big disk space is also required.

  New partitions will be smaller, but first 2008_1Q partition size will be unchanged, and I'll need to reclaim the unused space somehow.

  You have a better/more rapid solution of ideas?

  with DBMS_REDEFINITION, you have no downtime.

• Best way to reduce the volume of the music when people speak?

  Hi, I have do this promo video which is mainly music... but there are pieces where people speak to the camera, and I need to slightly reduce the music. I usually use keyframes on the waveform, but it's quite of your time, and if I edit the video in the future, audio keyframes align properly. Just wondering if there was any easier way to do it. Thanks, Neil

  Easier way and the industry standard is to use the Audio Mixer Panel...

  The organization track mixer automation and wil a create keyframes in real-time for a live mix.

  @the OP... It's a question of riding of the mixer, keeping an eye on the meters and using your ears.

  Mixing live is also easier if you are familiar with your editing and have an idea where the dialogue starts and ends.  Of course, your video helps with that.

• What is the best way to apply choice relational tables in the XML document?

  I've got an XML document from outside I turn with full DB XSLT document.
  
  Some parts of the document contain codes I want to tranfsorm to significant labels of relational tables in our database.
  
  On road is to disassemble the XML into the relational views and join these views with tables of choice and then back, this time with labels translated, using XMLElement, etc...
  
  Is there another way less heavy? For example,.
  
  Select updateXML)
  xml_dta
  ,'/ / section_to_translate/node_to_translate/variable / text () '
  ,(
  Select the label
  of table_recherche
  where Group = extractValue (current_node, '... / Group/Text () ')
  and code = extractValue (current_node, '... / variable/Text () ')
  )
  ) xml_dta
  from my_table
  where... criteria
  
  However, I do not know how to move from the current node to the extractValue function (if it is possible?.)
  
  Anyone done the second way?
  
  Thank you

  You didn't tell the version of your database, so I assume one of them later.

  You can include the part of the translation in the XSL transformation, by accessing an external research paper generated from the database beforehand.
