• Interesting question of sql 2

  Hi all

  I want to compare the data of the current column to another column of data, but for all values.

  Version: 11g

  with

  a as (

  Select 1 col1, 5 col2 from dual

  Union all

  Select 2, 10 from dual

  Union all

  Select 3, 15 from dual

  Union all

  Select 4, 20 from dual

  Union all

  Select 5, 25 from dual

  Union all

  Select 6, 30 from dual

  Union all

  Select 7, 35 from dual

  Union all

  Select 8, 40 from dual

  Union all

  Select 9, 45 from dual

  Union all

  Select 10, 50 from dual

  Select * from a;

  For example, I want to compare for each given col2 to all data in col1. I want to create a new column and if col1 contains 5 then he should write Yes, another no. If col1 contains 10 then yes other no. So for the example above, the output should be as below.

  1    5   Yes

  2    10   Yes

  3    15   No

  4    20   No

  5    25   No

  6    30   No

  7    35   No

  8    40   No

  9    45   No

  10    50   No

  Thank you

  Hello

  I suggest EXISTS, as Rahul showed in response #7.  To get the exact results you requested, use it like this:

  SELECT a.*

  CASE

  WHEN THERE IS)

  SELECT 1

  Of an a2

  WHERE a2.col1 = a.col2

  )

  THEN '' Yes. ''

  ANOTHER 'no '.

  Flag of the END as the

  A

  ORDER BY col1

  ;

  You can use a subquery IN rather than an EXISTS subquery, like this:

  SELECT a.*

  CASE

  WHEN IN col2 ( )

  SELECT col1

  A

  )

  THEN '' Yes. ''

  ANOTHER 'no '.

  Flag of the END as the

  A

  ORDER BY col1

  ;

  An outer join, as suggested in the response to #4, Nimish is good, too, but if col1 is not unique, you may need to use SELECT DISTINCT (depending on your needs) which will be ineffective.  Solutions using the set operators UNION or LESS will be as ineffective.

  Is there a solution with the analytical functions windowing or something like that?

  Yes, but it's inefficient and complex.  If you really want to try this, see:Re: getting the value of a column based on another column

  Why do you want to use an analytical function?   What is the problem with solutions already posted?

  The book is related to the exam 1z0-051. I'm not sure it's the best way to learn SQL from scratch. However, since once you know a little SQL book is useful, though sometimes, some might say t make sure that you get enough practice.

  However, it doesn't seem to be a book for Oracle SQL Fundamentals II, although I saw somewhere that it will be published before the end of the year?

  Don't worry in the short term. There is a review of SQL, you may want to consider longer term (1z0-047), but which is advanced. ISBN-13: 978 - 0071498500 probably apply the material (but does not focus on the review... maybe it's a good thing).

  Which is the best db Oracle. Download for Windows XP that I can put on more than one computer, it is better for my sql certification?

  Oracle is resource intensive; and more as it increases version numbers.

  10g XE [http://www.oracle.com/technology/products/database/xe/index.html] is perfect, EXCEPT that it is 10g 11g not and cannot indicate features of 11g but its greate from the manageability perspective.

  11 GR 1 material has a much higher footprint, but course has all the features.

  Unfortunately, it's a choice s one or the other. and historically the windows uninstaller can be an ightmare.

  I think that I must really be suggesting you look at virtualization - example: [http://www.virtualbox.org/] to run Oracle 10 g XE at first... but then again I am not sure if I'm over complicating things and have not tried it myself.

  Versions of the database newever and reviews using the SQL syntax that is no longer compatible with ansi standards more late especially in the use of the joins of tables in my humble OPINION.

  Can I take the exam SQL 9i or it is no longer used (can't seem to download from anywhere?)

  You can take the exam but its is no longer available for download. REF for example unable to download Oracle 9i database (any version)

  Can I take the exam at the Oracle headquarters or an authorized service center, without their own path?

  You can take in some centres of Pearson VIEW [http://pearsonvue.com/oracle/locate]. (1z0-051 can also be taken online).

  Thank you very much

  If you want some tutorials to practice simple SQL online be sure to visit [www.w3schools.org] but attention to other SQL dialects. This site is safe certification, but there are many who are not.

• Question of SQL monitoring control 12.1.0.4 clouds

  All the

  I used 12.1.0.2 EM cloud control for awhile and since the run to monitor SQL screen I have had direct access to bind variables in the SQL statement monitored.

  

  This feature doesn't seem to be available in 12.1.0.4, or, if this is the case, it seems to be very hidden...

  Clues on where I can easily find this information from within the EM CC on 12.1.0.4?

  We have an answer!

  In the main, (followed by executions SQL) view SQL monitor locate the SQLID you are interested and make your cursor the status"" column.  Click on the status icon-

  This will bring you down to the detail of SQL executions and to the right you will see the "View report" button that is not monitored in the other view.  Click on it and you have your information variable bind in the report.

  Thank you!

• IAAS configuration question - database SQL

  I have questions, get the IaaS of vRA setup part.  When installing, I get an error message saying 'domain user iwic\vra.svc is invalid or the database to access denied.  Validation error 1385. "This has occurred trying to connect to a SQL cluster and with a local installation of SQL on the server of IaaS.  I excluded the problems of firewall, ensure that the vra.svc has full right to SQL server, verified password admin and correct username.  At this point, I'm stuck and looking for help on getting this Setup is complete.

  

  The issue ended up being with the port number of the SQL instance.  The port number for this instance of SQL changed and I do not have this information.  When I was with SQL Management Studio to connect to SQL server, it requires a port number during installation of vRA you must know the correct port of the SQL cluster number.

• question about SQL and VMDK places

  Hello world. Im kinda new here so please be gentle

  I'm confused on the locations of the files for sql.

  At this moment I have 1 with 3 vmdk files sql server executes a muscular 100 GB sql database.

  My disks are as follows

  1 OPERATING SYSTEM

  2 DB

  3 newspapers

  They are all thick and they are all stored with the virtual machine in the virtual machine configuration.

  It lies in a cluster HA/DRS and we use them both.

  The question boils down to performance.

  If my VM is stored on DATASTORE_A and the VM folder on this data store has all the VMDK files in it, it would be safe to say that they are all on the same disk as much as vsphere is concerned.

  Now to get best performance, I want to separate my VMDK files to separate data (with faster operation) warehouses to avoid conflicts of drive on my current data store. What is the right way to go about this?

  How separate you your VMDK to other data warehouses, and enjoy other performance data store? WE do not use DTS at all so im sure it although we use HA/DRS in our group... and yet, I don't think that it is important in this case... just more of an FYI.

  What do you do to get your SQL servers to run in vmware?

  Seems like a basic question.

  The answer seems easy. Separate disks so that they do not fight.

  'S virtually done it with VMDK but the data store underlying is 1 speed and they all exist on this subject, so... How to separate them at that level for best performance?

  Also... once I keep them separated, how can I keep my sanity by knowing my VMDK are not with the virtual machine? This kind of made a mess . Of course the performance takes a front seat for my mental health.

  Thank you all

  1. If I sVmotion my other vmdk files via the advanced options of one in another data store, it will create the files folder structure based on my VM name and place the vmdk inside?  (I guess I could just test it and see).

  Yes, the VM configuration file (.) VMX) will be modified to point to the new location of the virtual disk. You can use the virtual machine property editor to check for this, once the Storage vMotion.

  2. with regard to the disk controller, I assume you mean a virtual controller by VMDK in the vmx / correct the settings of the virtual machine and not a phyical on the hardware controller? (IM pretty sure I know the answer here but I just want to be clear).

  Yes, the virtual controller is correct.

  If so, what type of controller? LSI Logic or it would benefit all a paravirtual adapter?

  As long as your operating system is supported, go with the PVSCSI every time - especially for newspapers and the controller file data.

• General question about sql DB to vcenter

  Basically, we need to know how many connections SQL DB to go from one instance of vCenter 5?

  It is dependent on host?

  It is dependent on comments?

  Is there a way we can we estimate how many connections?

  DBA SQL told us we have currently a large number of connections, but we do not think that this could be cauisng questions.

  vCenter uses a connection pool (10 by default as he answered already). This is usually done by web application to manage db connections required by multiple login sessions (no need to reopen a db for each session connection... open a db connection sometimes takes more time that select it dumb that they do).

• Question about SQL * connect more in the syntax

  Good evening
  
  I can connect successfully from the client to the host using the following command:
  

  0 19:40 [Oracle] [23G] [569M] E:\Client>sqlplus scott/abc123@dbca
  
  SQL*Plus: Release 11.2.0.1.0 Production on Sun Aug 22 20:01:56 2010

  But I wanted to omit the password, so I tried:
  

  0 20:03 [Oracle] [23G] [590M] E:\Client>sqlplus scott/@dbca

  thinking that SQL * more tempt me the password but, if it does at all. I tried in vain a few variations. I read the specifications of command line for SQL * more and it seems that this command should work.
  
  Questions: What is the problem with the command I typed and what is the correct syntax?
  
  Thank you for your help,
  
  John.

  To omit the password using connect scott@dbca , but do not connect scott/@dbca of sqlplus.
  or sqlplus scott@dbca

• Question of SQL statement

  I have this PreExpression at a stage of SQL statement:

  Locals.SQL_LatestResult = "SELECT UUT_RESULT.ID, UUT_RESULT. UUT_SERIAL_NUMBER, UUT_RESULT. START_DATE_TIME UUT_RESULT WHERE (((UUT_RESULT. UUT_SERIAL_NUMBER) =------"' + Locals.serial + ' \ ') AND ((UUT_RESULT." START_DATE_TIME) = (SELECT MAX (UUT_RESULT2. START_DATE_TIME) OF UUT_RESULT AS UUT_RESULT2 WHERE UUT_RESULT. UUT_SERIAL_NUMBER = UUT_RESULT2. UUT_SERIAL_NUMBER))); »

  Locals.SQL_LatestResult has this value after the PreExpression:

  SELECT UUT_RESULT.ID, UUT_RESULT. UUT_SERIAL_NUMBER, UUT_RESULT. START_DATE_TIME UUT_RESULT WHERE (((UUT_RESULT. UUT_SERIAL_NUMBER) = "15514011") AND ((UUT_RESULT. START_DATE_TIME) = (SELECT MAX (UUT_RESULT2. START_DATE_TIME) OF UUT_RESULT AS UUT_RESULT2 WHERE UUT_RESULT. UUT_SERIAL_NUMBER = UUT_RESULT2. UUT_SERIAL_NUMBER)));

  I get the number of records = 0, if I run the sequence.

  If I copy the exact same SQL query in access I get what I want to know a record.

  If I remove that part of the query:

  ((UUT_RESULT. UUT_SERIAL_NUMBER) =------"" + Locals.serial + "\") "

  I get 388 records which is correct and it run directly in access.

  What's not here?

  I was too fast for this post... it's my fault, the database link was wrong, so data were there...

  Statements are very good!

• Two questions: Running XP and have some interesting questions at the start and with IE.

  Hi, I try to wear the IT hat and works to clear up some questions on my mother's computer.  #1 I guess that the computer was shipped with a version of Corel Photo software on it and we cannot get rid "Installer" messages at the beginning upward.  We tried to remove the program and the same message comes back to tell us that "Installer can do the requested action without the CD/program files" it gets about 6 of these reviews that it must close any until the computer will continue to boot the system.  Please, please tell me how to get rid of this.  I tried to install the 'Installer' update to see if that would make the difference and nope.  I also tried to remove the Corel file via CCleaner and got the same message.  I do not have the program disc, I don't want to program... I want to just get rid of it!

  #2 when entering address in the Internet Explorer address bar, the browser opens a second browser instead of going to the requested site.  For example, when I open my Internet Explorer and say go to the top of the address bar and typewww.google.com, instead of going to Google, it opens a completely separate browser.  When she did this, it's EXTREMELY SLOW!  until you think that IE went unresponsive and then finally opens the second browser.

  I'd appreciate any help!  I'm trying to solve these problems, while I'll be staying here so that I can leave him a computer running.

  Thank you!

• BlackBerry Z10 stupid but very interesting question on your blackberry microphone remote

  Hello

  I have a question that I now have a fight with 10 friends around a table.

  There is a rumor in my country that your cell phone can be heard even when you talk, when he's just sitting idle in stand-by but turned on. As a person can open your microphone from far away and listen to whatever it is you're talking to the table.

  My question is, is it possible? How is it possible?

  Having been to many of the foundries around the world, I can say that it is feasible as possible but almost certainly not practical.  He needs collusion on a scale from Golden to be implemented.

  Any suspicion of a phone, this would result in it being gutted, the tops taken out of the chips, and probes introduced by expert monitoring and chip design.

  What is possible, it is for your position to be checked by means of a phone and a phone to be cloned and calls intercepted. If you talk on the phone, the call can also be intercepted at the end of service provider and to recent leaks, it is a certainty that the Governments that, with the United States it seems to be one of the worst (or best) with a massive mainframes, passing to sift through all the calls of keywords to trigger.

  Unfortunately, it's the world we live in now.

  Hope, your dinner party went well and that you kept your dinner talk about hazardous materials.

• Interesting question of scrolling

  Hi everyone, I have a problem with scrolling in my area

  The page layout, I currently have is:

         vfm0 = new VerticalFieldManager(USE_ALL_WIDTH | USE_ALL_HEIGHT | NO_VERTICAL_SCROLL | NO_VERTICAL_SCROLLBAR);
          add(vfm0);
  
          vfm1 = new VerticalFieldManager(USE_ALL_WIDTH | VERTICAL_SCROLL | VERTICAL_SCROLLBAR);
          vfm0.add(vfm1);
  

  and I add a created custom field to vfm1.

  However, every time I scroll the focus passes power to another, but the screen does not scroll down UNTIL the last field wins the update. Once the last field acquired focus, scrolling further causes the screen to scroll down.

  I tried to add simple labelfields at the vfm1 and it scrolls perfectly but created custom fields are causing the problem.

  Can anyone think of what may cause this effect?

  In the custom field is created, I replace the onFocus() and the onUnfocus() but I do not see why this would have caused this problem.

  I found the problematic code.

  So the custom field I have added is horizontalFieldManager and inside, I bitmapfield

  Now, in the horizontalFieldManager I crushed focus... that makes no sense since fieldmanagers don't really get the focus (as in the past, I read in this forum).

  At the same time, I was the substitution of development for the bitmapfield as well.
