• Any difference between the separate function and aggregation in sql query cost?

  Hello
  I've run many models sql stmts - such as:
  one) using a single table
  (b) using the two tables, using simple joins or outer joins
  
  but I didn't notice a difference in sql stmts in cost and implementation plan...
  In any case, my colleague insists on only using the aggregate function is less expensive compared to
  separate... (something I've not confirmed, that is why I believe that they are exactly the same...)
  
  For the situation described above under 1 sql... We could for example use
  

  select distinct deptno
  
   from emp

  select count(*), deptno
  
   from emp
  
   group by deptno

  select distinct owner, object_type from all_objects

  select count(*), owner, object_type from all_objects
  
  group by owner, object_type

  Have you ever found no difference between the two...?
  
  Note: I use Ora DB 10g v2.
  
  Thank you

  Alexandre Gelin says:
  function separate and aggregation are for different uses and can give the same result, but if you use the aggregate function to get the separate records, it will be expensive...

  really? I find them almost identical to 11g. Actually GROUP BY is almost always more fast for me in the old days.

• What is the difference between the area and the period key based?

  Hello
  
  In version 4.0 of the Apex, what is the difference between the region and the point function key (button created under article)?
  
  Thank you
  David...

  Hi David,

  I think that they have not changed, it is always the same as in the APEX 3.2 or 3.1...

  Region of buttons is placed on the top or the bottom of the region, the option buttons are treated like any other item and are placed inside the area as the other points.

  For more details, see the APEX Application Builder User Guide.

• Difference between the G20 and G25 models

  Hi people!

  I searched your laptop and I was amazed by the Qosmio.
  When I was going to order it, I noticed that there are many models of the G20 with different specifications. Also, I found G25 on internet research and found no difference between the G25 and G20 except receiver TV G25 is NTSC and G20 was released on March and G25 was in June. Instead, they have the same specifications for the hard drive.

  I live in the Portugal and the model Qosmio I can find that this is the G20-118. I was looking for the model that has 2 x 100 GB SATA HD, but cannot not thought about it.

  Internet research I found Qosmio G20-111 which has 2 x 100 GB SATA HD, but on the web page mentioned that it was a Pentium III processor (ridiculous, isn't?). I was looking for more reliable information.

  Already searched for toshiba pages and found no specifications for all models I found 490LS on the research on the web as the G20 - 102, 105, 106, 108, 109, 111, 118, 123,...

  Can someone help me with this? Are there any reliable web page where I can see the differences between the models? is there a .pdf or anyone who can please give me some advice?

  Money is not a problem at this time to acquire the laptop, I'm looking for only the laptop performance more!

  Best regards
  João Pereira

  Hello

  It of very difficult to say what camera is best, because there are many models with different parts.
  However, I found page with description of the G20 and G25.
  Take a look at this link.

• What is the difference between the stop and restart?

  What is the difference between the stop and restart?  I feel that stopping closed all processes, completely erases RAM memory and clears the cache of the processor.  I need to know if 1) this is a correct assumption and 2) which is better for daily maintenance of the system.  Thank you in advance.

  Hello Jeremy_1976,

  Your support when the judgment is correct. Basically, it stops the process and completely turns off your computer. Reboot, however, temporarily your PC stops, then turn it on again. This happens usually when Windows updates are installed. After installation, the system is restarted (rebooted) so that any update has been successfully installed and works as it should. You can be a little mixed upward the reboot and the hibernation. Reboot is, as I have indicated previously, basically a reboot of your machine. Ultimately, your PC is on again after a reboot. However, hibernation, stores all data currently in memory in a special file, then the PC turns off. When you then turn on your PC, that is, coming out of hibernation, hibernation files is used to restore the status of the PC than when you initially put into hibernation. In other words all the programs you had open before will automatically open and be ready to use hibernation.

  Hibernation or sleep for that matter is for short-term use. It is normal in Hibernate, or sleep if you want to be away from your PC for half an hour or so. If you leave more than I suggest you stop completely.

  A point to remember about hibernation is that, if you use put into hibernation, you can't, once you get out after hibernation, install programs or updates. You have to stop and restart normally to do.

• "There is a time difference between the client and the server"

  Unit 4.0.3

  Everything worked very well, and all of a sudden, I'm not able to connect to the server unit using any domain account. When I enter the domain/name username/password, I get this error message:

  ************************************************

  The system is unable to log on due to the following error:

  There is a time difference between the client and the server.

  Try again or contact your system administrator.

  I can use the same domain account (unityinstall) and the journal in other machines. I can connect the machine to the unit using a local account. There is no time difference between the DC server and unity.

  Need help,

  Thank you

• difference between the view and the procedure

  Hi Master,

  Today I received a request from my senior technical leader... !!

  Q > what is the difference between the view and the procedure?

  I got response like this...

  A view represents the logic of one or more tables/views. It won't take no place in db... It is a virtual table, query will only store in db... useful

  for safety... If the main table has obtained changes... automatically discovers also change... etc.

  Proecudure is a db object will be performs a perticular action... It may or may not return values. ?

  But somehow, he isn't happy... He expects more... .very close view of diff. b & w and procedure.

  Please explain it to me...!

  Hi Blu,

  Thanks for your replies...! But we think if notice and procedure will be the same no matter what point of view? Both are the same? If Design view... We can create a stored procedure?

  How a view and procedure may do the same thing?  They are two different things with different objectives.  You use the correct one depending on what you want to achieve; they are not interchangeable.

  And another question...!

  (Q) how you will store Japan, characters of China in a database table? will there be a new feature in Oracle 11 g?

  (A) I use dbms_lob package? Japan/China characters are multi byte characters... so we can use the nclob data type?

  is this correct... ?

  No, it not there no novelty in Oracle 11 g for the storage of Japanese or Chinese characters, because there is already a feature for their storage in previous versions as well.  It is determined by the parameters characterset and nationality that you use when you create the database.

  Why would you choose to store them in a LOB using DBMS_LOB?  Yes, they have multibyte characters, but if you have configured your database for the correct character sets, for example using UTF - 8, then you can store the characters in VARCHAR2, like any other language.  The only difference is that the storage of 4000 bytes limit still applies, so you maybe isn't able to store 4000 multibyte characters in a varchar2 column 4000 single-byte, it can be as little as 1000 characters if they are all characters in 4 bytes.  (Note: 12 c limit in SQL can be increased up to 32,767 characters, to harmonize it with variable varchar2 PL)

• What is the difference between the model and its clone in VMware?

  What is the difference between the model and its clone in VMware?

  Clone

  A clone is a copy of the virtual machine.

  You can't convert back the cloned Virtual Machine.

  A Clone of a Virtual Machine can be created when the Virtual Machine is running

  Cloning can be done in two ways: Clone full and linked Clone.

  A full clone is an independent copy of a virtual machine that shares nothing with the parent virtual machine after the cloning operation. Continuous operation of a full clone is entirely separate from the parent virtual machine.

  A linked clone is a copy of a virtual machine that shares virtual disks with the virtual machine of parent on a regular basis. This preserves disk space and allows multiple virtual machines to use the same software installation.

  Cloning of a virtual machine can save time if you are deploying several similar virtual machines. You can create, configure, install the software on a single VM and then clone several times, rather than the creation and configuration of each virtual machine individually.

  Model

  A model is an original copy or a reference image of a virtual machine that can be used to create many clones.

  Models can be turned on or edited and are harder to change than usual of virtual machine.

  You can convert the model to the Virtual Machine update model base with the latest released patches and updates and to install or upgrade any software and still convert to template to use for the future deployment of Virtual Machines with the latest patches.

  Convert virtual machine model cannot be performed, when the virtual machine is running.  Only the Clone to the model can be performed when the Virtual Machine is running.

  A model offers a safer way to preserve a virtual machine configuration that you want to deploy several times.

  When you clone a virtual machine or deploy a virtual machine from a template, the cloned virtual machine resulting is independent of the virtual machine or the original model.

• Difference between the USA and the Australian version of the EP 11

  There is a significant price difference between American and Australian from Adobe. For an upgrade, it cost US $ 80 in the United States and 120 AUD in Australia. At present, the AUD is stronger than USD!

  I'd be any disadvantage if I chose to download from OUR site?

  There is no difference between the USA and AUD software.

• The difference between the background and process

  In the document 'A BEA Tuxedo ATMI application using C programming', he mentions "by context basis" and "process basis. Please tell me the difference between the context and the process? Thx a lot.

  Bill,

  A context of Tuxedo is a connection to Tuxedo, also known under the name of an application association.

  If you do not use the TPMULTICONTEXTS flag when calling tpinit() and you do not specify a value MAXDISPATCHTHREADS is greater than 1 in the UBBCONFIG file for the servers then a framework and process will be the same.

  tuxputenv() is similar to the C library function putenv() function. tuxreadenv() reads a file and running tuxputenv() for each line of the file. tuxgetenv() is similar to the C library function getenv() function.
  The variables must be set before the time they serve. Thus, a tuxputenv() for a Tuxedo as the TUXCONFIG, TUXDIR, or WSNADDR system variable would be effective before when a client called tpinit() but would have no effect for a customer who has already called tpinit().

  Kind regards

• What is the difference between the CACHE and the PIN code?

  What is the difference between the CACHE and the PIN code?

  Cached, it's when you specify CACHE as part of a CREATE or ALTER an object to say Oracle when the blocks are retrieved this object these blocks should be put to the most recently used end of the LRU (least recently used) list in the buffer cache when a full table scan. Under normal circumstances, when the blocks are retrieved in memory, in that they are placed least recently used end of the LRU list. This means that the data that was most recently viewed typically will remain available in the cache buffers for awhile. Therefore, subsequent runs of the same query should find these blocks already in the buffer cache and not to recover disk again. When you use the CACHE, you say you want to put the blocks retrieved at the end of the list, which means that they will be the first blocks "aged" off the buffer cache when more space is needed.
  A few reasons to use the CACHE are:
  (1) for tables of small (only a few blocks that must be read to retrieve the entire table).
  (2) when you do a select statement returns a huge amount of data, and you do not necessarily have if wait for the query to run any time soon. In both cases, you give Oracle an opportunity to eliminate the blocks quickly to make room for more 'necessary' blocks instead of having to follow in the LRU list.

  Pinning is when you want to keep the objects in memory and to prevent them from being aged by the normal mechanism of the LRU. You use the INVALIDHTOMEH to "pin" PL/SQL code in memory, so that users are not experiencing intermittent slowdowns when code gets years out of the shared pool and must be recharged.

  The bottom line is that caching can blocks be moved quickly while pinning retains the information in memory to avoid the re-loads.

• Difference between the view and the materialized view

  Hi all
  
  Can someone tell me exactly the difference between the view and materialized views?

  Hello

  View:-this is a virtual table means table is there, but in fact is not there...
  see how to create a view...

   create or replace view aaa as select * from emp; 
  

  Now, when we choose the AAA, he will show me all the data that would be returned by running a query "Select * from emp"... Thus, all data will come from table iteself.
  View in itself is nothing but just a Sql statement that is used to create the view, in this case definition is "select * from emp.
  Any update in the database table Emp which is in our case, would automatically result in the view...
  Any changes (all dml) will actually update the base table (conditions apply *)

  Now the materialized view:-this is the same as except that it is not a virtual table... This will be created separately and it will acutally hold the result of the query that is used to create it. Any subsequent changes in the base table only will be included in the opinion of M M view is refreshed...
