• Query the number of columns have data in a Collection

  Hello

  Apex 4.2.

  I use the EXCEL2COLLECTIONS plugin to import csv data into a collection.

  I am now validate the collection and would like to know the number of columns in the collection were given.

  For example, if my collection has less than 10 columns with data, then I want to generate an error

  Is there a way to do it

  What type of validation

  You said:

  I am now validate the collection and would like to know the number of columns in the collection were given.

  and

  Otherwise, I should raise an error or enter an error indicator and the error message in columns 11 and 12

  So one could assume that aspect was already developed.

  The short answer is that without knowing the details of what you are trying to do, how your do it, and how you have reached: don't know.

  I expect this kind of import of data includes several pages forming a multi-step wizard, so there are a lot of possibilities. For example, use it in a cursor FOR loop to set the above error flag and message columns, then conditionally branch to a report with errors page if error indicators exist in the collection, or the next page of the wizard, if they are not.

• Making the best use of space for the quality by balancing the video bitrate and audio settings?

  I have a few questions about the first export still / encoding in encore. I am trying to create a dvd single layer, where I maximize overall quality using as much space as possible.  The video is 97 minutes, SD 720 x 480, 29.97 FPS and consists of interviews for the most part, as well as b-roll hd cameras and stills, rare title graphic card.

  1. I can use dynamic link to send the sequence that appears to maximize the space available, however I have heard that using DL is generally frowned upon and I myself cannot tell what settings it uses (for example vbr, 2 pass, etc.). Is my interpretation that DL is not the ideal way to go wrong? If DL is just as good as a separate output, is there a way to know what parameters it uses?

  2. I used a bitrate calculator and tried a Min: 3.5 target: 5.5 Max: 8 audio output PCM and I found myself having a little more than 400 MB of unused space. When someone recommended a Min: 5.5 target: 7 output Max 8.5 the file size is too large with a simple DVD layer. I read that it is recommended to use an exit instead of PCM, if the video is over an hour audio Dolby. My question is is it a best practice to balance needs of flow rates and audio and video? I realize, of course, by using more data PCM is 'better', but it is usually best to go on the road to dolby and have more space to increase your video bitrate? What is the audio difference type that requires a high-end system to discern? Y audio data loss is worth for the benefit of video bitrate higher?

  I know it's a lot, just trying to maximize space to get the best possible performance. Thanks for any help/advice you can provide.

  -Nick

  As most of my videos are closer to 2 hours usually, I always used Dolby Digital, PCM takes so much space and I prefer to use this space to increase video quality.

  Note that by default, if you import a .wav (PCM) file into Encore, it transcode automatically that Dolby, unless you have changed specifically the default settings of transcoding in Encore.

  A decent basis for coding rule is 560/minute = bitrate, so 560/97 = 5.77 and I usually just round off a little for menu overhead and margin of safety. This requires using Dolby to 192 k, so I would use 5.6 average bitrate.

• How to create a Subscriber variable to the network & OnDataUpdate for Variant data type?

  Looking at the example C:\Documents and Settings\All Users\Documents\National Instruments\MStudioVS2008\DotNET\Examples\NetworkVariable\Basic\cs\Subcriber.2008, how can I create a subscriber to the network variable and OnDataUpdate for Variant data types?

• How can I dynamically select the shared Variable API programming data type?

  I am trying to create a configuration of open connections of variable shared using the programming API. It seems to me that the cleanest way to do would be to put one "open and check" routine in a loop, then call it for each variable in the library.

  The question that I am running is that I have different types of data in my library (to help a server Modbus i/o and data types 'boolean' and 'single' in my library.) How can I dynamically select the data type of the shared variable API?

  See the attached snipit.

  Thank you

  What I ended up doing was doing a Subvi to open, read, write, and close each data type, I use the packaged in 4 polymorphic SubVIs (polymorphic Open, read, etc...)

  Now all I have to do I drop in the polymorphic Subvi and it switches automatically to the appropriate data type

• How to change the appearance of the number using images?

  Hello!

  I want to design a numbers on photoshop and make an animation count numbers.

  I have sucsess to do animation account numbers, but I don't know how to make the numbers I want.

  for example

  1 = 1. jpg / psd 1.

  2 = 1. jpg / psd 1.

  up to 9

  Ty!

  There is no automatic way to do a countdown to use images instead of numbers, but there is a solution.

  It is a type of advance but the here is one of the approaches that I could take.

  • Each of your images photoshop exports a separate numbered file their numbering from 1 to 9 and put them in the same folder
  • Open the dialog of the import in AE by double clicking on the project Panel or by selecting file > import > file and select one of the images in the order
  • Make sure part options open dialog is visible and check the box that says (any file type you choose) JPEG sequence is checked
  • Now add your images are a movie in the timeline with all images in order
  • Add your movie to image sequence to the timeline
  • Activate the time-remapping set up the synchronization of the images to change the speed that you want to change them

  There are several ways to control the speed of the movie you made from your images. You can set the frame rate in the interpretation of file or use time or use an expression to call a number of image based on time.

  You could also import all your images individually, drag them to the timeline and then set an out point to say 1 second for all layers, then the wizard from keyframe to the sequence of layers and even define an overlap and the transition between layers if you wish.

  To learn more about time remapping type time remapping in the search field help in the upper right of the AE and extract the help files. Do the same for the layers in sequence and the sequence of images if you need to.

• How can I know the number of columns in a TYPE?

  Hello

  It is a type of associative array definition. A table has no columns. It is a collection of elements (variables or values). An array location is usually called a cell.

  The standard method Count() exist in Oracle for all table types.

  As for the definition of the table, as in structures, variables make the table contain - associative array is defined in the PL/SQL code and does not exist in the layer of metadata to the database as a new user-defined type. For the definition, you must read the declaration of PL/SQL defining the table.

  Note that there is very rarely the need for associative tables in PL/SQL - 99% of the time they are used without any idea as to what as a table associative is also.

• Problem with the length of a CLOB data type

  Hello
  
  In my application, I have a page with an interactive report of written blogs - on this page, you can add a new blog (text box - CLOB data type), discovered a blog or edit a blog.
  There is something going wrong with the size of the blog text. I know APEX cannot accept that 32K text and I've seen the great value saving thread, but this isn't the solution to my problem.
  
  The problem is that when I add a blog with say about 4000 characters, it is saved in the database, but the interactive report, when I click on the view or edit icons for this blog, the blog text field appears empty. For small items (< 4000 characters), there is no problem.
  Anyone know why this is happening and how to fix this?
  Thank you!

  There seems to be a bug in the calculation of the value of the element Source when the Source Type is a SQL query and the data type of the selected column is CLOB. I'll file a bug for this. For now, I have demonstrated how you can use a type of function PL/SQL source instead. Please see point P3_TEXT:

  beginfor c1 in (select blog_textfrom blogwhere blog_id = :P3_BLOG_ID) loop  return c1.blog_text;end loop;return null;end;

• How to calculate the number of days between dates

  How can I determine the number of days between 2 dates? Say today and 10/07/46
  
  Thanks Bob

  You could do it like this:

  Photoperiod var = 1000 * 60 * 60 24; number of ms in a day

  var today: Date = new Date();

  var every time that: Date = new Date (1946,6,10);

• The views using materialized for data warehousing and reporting

  Hello
  
  I would better understand the materialized views in Oracle in particular the use of the option: REFRESH QUICKLY ON COMMIT. The oracle database, we care is a PLM application and any of the tables to apply using the primary key constraints. Instead, the application uses a separate schema to store the key values for each object/save in the database. I would use Materialized View to the creation of a data warehouse smart to transfer only the lines that have updated since the last refresh of the warehouse. My understanding of the materialized views you can't define a until and unless you have a primary key constraint. It's fine and understandable.
  
  Can we have an oracle separate sid something like WSHD - data warehouse and using the database between the main site links - site WSHD always transfer lines that have changed since the last refresh with REFRESH QUICKLY ON COMMIT option? (Note: this is taking into account the fact that a database primary key constraints defined on the paintings of masters.)
  
  I guess you have to install MV NEWSPAPER tables on the main table and then create a materialized using option QUICKLY ON COMMIT REFRESH view?
  
  Am I wrong?
  
  Will there be another option for the transfer of the lines of main tables in the data warehouse in Oracle?
  
  Thank you very much.
  
  See you soon.

  1. you can't define a materialized as ON COMMIT REFRESH in a separate database view. It must be in the database even if it's to refresh commit it.
  See http://hemantoracledba.blogspot.com/2008/06/mvs-with-refresh-on-commit-cannot-be.html

  2. you don't have to have a primary key to set a MV. You can set a MV WITH ROWID (except if you re-create the source table, you need to do a refresh of the MV because ROWID changes).

• How to store the value in the database using UTF-8 Content-Type

  Hi all

  I created a web application that uses soap services.

  I want to store data in my data base oracle in Hindi language, so I configured my compiler Jdeveloper in UTF - 8 as well as my oracle database also supports utf - 8.

  but when I store hindies data through web service (Soap service), value was stored as? in my database.

  where as when I store data hindies without web service data is stored as unicode (& #23455 ;) who can be recover in hindi font I have my jsp pages.

  Here is my sample code:

  package com.example.service;

  import com.example.bean.LanguageBean;

  import com.example.conn.OracleDBConnection;

  import java.sql.Connection;

  import java.sql.PreparedStatement;

  pst.setString (eng, 1);

  pst.setString (2, hindi);

  int i = pst.executeUpdate ();

  result = i + "Notice inserted successfully;

  } catch (Exception ex) {}

  ex.printStackTrace ();

  } {Finally

  try {}

  OracleDBConnection odbc = new OracleDBConnection();

  odbc.closeConnection ();

  } catch (Exception ex) {}

  ex.printStackTrace ();

  }

  }

  return the result;

  }
