  See VARCHAR2 and VARCHAR in the section of the doc of the SQL language data types
  >
  The VARCHAR2 data type
  The VARCHAR2 data type specifies a variable-length character string. When you create a VARCHAR2 column, you specify the maximum number of bytes or characters of data it can hold. Oracle then stores each value in the column exactly as you specify, provided that the value does not exceed the maximum length of the column. If you try to insert a value that is greater than the specified length, then Oracle returns an error.

  The VARCHAR data type
  Do not use the VARCHAR data type. Use the VARCHAR2 data type. Although the VARCHAR data type is currently synonymous with the VARCHAR2, VARCHAR data type is programmed to be redefined as a separate datatype used for character strings of variable length compared to different comparison semantics.

• How can I ignore the differences between databases when reading data from a database?

  My boss wants me to create a text parser that analyzes the sentence below and executes a SQL query.

  "' get the table field1, field2, field3,..., Manyfield [where to SQL conditional statements].

  This corresponds to "select Field1, Field2, field3,..., table Manyfield where blahblah".

  Since different DBMS have different timestamp formats, this sentence should be changed for each DBMS.

  Ignore the differences is to do anlayzer that converts a certain type of timestamp string to one that adapts to each DBMS complex a text.

  But it seems ridiculous to adopt this solution when there might be an elegant solution.

  LabVIEW Toolkit of DB is not able to hide the differences.

  Does anyone have a better idea that I do?

  I remember having a problem like this when you are working with an older version of an Oracle server. I was able to change the session by setting the 'NLS_TIMESTAMP_FORMAT '.

  This page might be of interest; I found this, when searching for "NLS_TIMESTAMP_FORMAT".

• How can I fix the link between adobe and windows if I see .pdf not win32 application

  How can I fix the link between adobe and windows if I see .pdf not win32 application, without the disc?

  "Adobe" is the name of the company that provides a great many different applications.

  Adobe Reader is free and allows you to view pdf files.

  Adobe Acrobat is expensive and allows you to create, edit and view pdf files.

  Assuming that you are referring to the reader, uninstall all the versions of it using the control panel > add or remove programs.  Then either

  1. go to http://get.adobe.com/reader/?promoid=BUIGO and download the current version (remember to uncheck the box to install McAfee Security Scan Plus.

  or

  2. go to http://www.foxitsoftware.com/Secure_PDF_Reader/ and download Foxit Reader, a small pdf reader and many more.

  Then, install the reader that you have downloaded.

• How can I compare the differences between two files After Effects?

  I have a major problem.  I was working on special effects for a film.  In After Effects, when I change siggificant, I often have to register under and create a new name so I can go back to the old work if necessary.  It comes in a case, I have come back from earlier works.  If I use these two files After Effects allows you to create multiple clips of effects.  And I do not remember just where you look at it, it is better.  Does anyone know a good way to compare the differences between the files?

  One thing to keep this conversation on the right way: I know that I did a stupid thing.  I've never done this before so can we please not spend a lot of time on how to avoid this problem and stick to how we solve this problem?

  If you encounter difficulties to identify differences in the old and new versions, you can use this procedure:

  To avoid confusion, I'll call your former company and your most recent compositions CompB comps.

  CompA drag "New Comp" icon in the project window.  This will create a new temporary layout that contains the nested CompA.

  Drag in your new COMP CompB temporary ensure it aligns image for image with CompA.

  Place the top layer (CompB) difference.

  Now, when you play through the comp, you'll see differences in color at a time where the comparison and CompB are not identical.

• How can you tell the difference between Microsoft Windows 8 Pro Full version and upgrade?

  For previous versions of Windows, for example, Windows 7, it was very easy.  Windows 7 Ultimate Upgrade has 'Upgrade' printed on the outside the box in the upper right, as well as on the discs themselves, while the full version does not work.

  See here for example of the box: http://fc03.deviantart.net/fs71/i/2010/193/e/0/Windows_7_Ultimate_upgrade_by_LucasVN.jpg

  For examples of records, see here: http://headsetchatter.com/blog/wp-content/uploads/2010/09/snapshot-1283367118.977272.jpg, - http://www.microsoftcheapsoftware.com/ekmps/shops/samehxm/images/microsoft-windows-7-ultimate-sp1-upgrade-[3] 148 - p.jpg

  With Windows 8 Pro, I can't find any distinctive feature.  I bought the full version and upgrade of Windows 8 Pro, but after their installation on several dozen calculates, I lost track of which boxes and discs are which.  And there seems to be no way to understand who is who...

  There is never any full retail versions of Windows 8, Windows 8 Pro box. Only Windows 8 and Windows 8 Pro OEM System Builder licenses were full versions. It's the best way to confirm.

  Since the release of Windows 8.1, in retail box copies are full versions.

  A3 landscape artboard. When the zoom is less than 100%. the appearance of the work (lines) in staircase, I can tell this resolution because something I have to zoom and it disappears. I understand the difference between vector and raster so... this kind of problem is like when you zoom too in an image and it becomes pixelated... but otherwise...!

• What is the difference between AXIEM and EMSIght? What are the benefits of AXIEM by EMSight if any?

  I wonder what are the differences between AXIEM and EMSight. Are associated with application? One is better than the other? Please explain.

  AWR estimated AXIEM most powerful plan EM Simulator around.   AXIEM is at the center of continuous research and improvement, while EMSight is only worked on if revealed serious flaws.  Here is a summary of the differences:

  Mesh

  • EMSight must mesh the nearest grid drivers using rectangles.  This causes the mesh to have more elements mesh when there are small and large geometries.  The grid should be small enough to capture the small geometry but then causes large geometries to mesh more.   In addition, angled or curved structures causes inefficiencies mesh.
  
  
  • AXIEM STS forms, rather than a grid.  In addition, the mesh can be rectangle or triangle.   This allows a much more efficient mesh.   AXIEM generally have a much more efficient
  
  
  • AXIEM contains the ability to process forms to clean geometries that cause inefficiencies of the mesh.  EMSight does not have this feature.
  
  
  • AXIEM can forms thick metal mesh, EMSight can not, and user must make approximations when thick metal will change coupling (loss is recorded properly with the thickness of the metal)

  Ports

  • The ports are for the most part similar, but parasites due on AXIEM ports are less.  In addition, the AXIEM has a side wall, thus the effects of not move of the terms of reference of the edge of the line are a lot less AXIEM in.
  
  
  • Ports can be added to most any place in geometry with AXIEM.  For EMSight, the ports are usually only added outside the geometry and have limitations to the aircraft on either side of the reference speaker.

  Problem solvers

  • EMSight does not have a low frequency Solver.  Stop low-frequency and then extrapolate to DC.  This usually works well, but you must take into account if the extrapolation is accurate.  AXIEM presents both a low and high frequency Solver so will do better in a low frequencies generally much better in DC.
  
  
  • Solver of EMSight scales O (n) ^ 2 for memory and O (n) ^ 3 for the moment.   It has a special algorithm to break the question of memory, but the question of time is the killer.  AXIEM has a direct Solver which scales in the same way and an iterative Solver which will scale O (nlogn).   In other words, AXIEM can solve a lot of bigger problems than EMSight.
  
  
  • Several AXIEM processes are multithreaded as EMSight.

  Speaker

  • EMSight is inside a perfect driver side wall.   This works well if you the circuit is in the same cavity.  If not, you must know the rules of them on to the forms of space of the flanks and how that much to extend the port could reference planes.   AXIEM is not here.   AXIEM does not currently have to simulate a perfect driver side wall.

  I don't know that I missed a few aspects of the tools.   From the point of view of the AWR that AXIEM is the tool of choice, except in a few cases have been EMSight may be required.

• What is the difference between OCÉ and (OCP and OCS)

  What is the difference between ECAS and (OCP or OCS).

  For example, I heard that OCS helps with the language

  and the marketing of a product.

  Could this be true as ECAS focuses on how to do things.

  and not so much things to a much higher level.

  For example, how do you set up, how you use it, how do you start, etc.

  Thank you Roger

  Roger,

  OCÉ Doghouse more. These certifications can be more CERT of intermediate or high level certificates. These were specifically developed for the gaps in the certification that did not match our OCA, OCP, hierarchy of the CMO.

  Generally, the CERT of the OCS tend to focus more on implementation. These certificates have been developed for the Oracle PartnerNetwork for areas of certification which specifically serve Oracle partners and qualify them for levels of specialization. These certifications are available for all candidates, but are directed towards members of OPN.

  I hope this helps.
