• SELECT SESSIONTIMEZONE FROM DUAL;

  Hello
  
  10g, I have:
  

  SELECT SESSIONTIMEZONE FROM DUAL;
  SESSIONTIMEZONE                                                             
  --------------------------------------------------------------------------- 
  +01:00                                                                      
  
  1 rows selected

  What setting should I change im my session to have:

  SESSIONTIMEZONE                                                             
  --------------------------------------------------------------------------- 
  Europe/Paris
  1 rows selected

  In the documentation, it is said:
  SESSIONTIMEZONE returns the time zone for the current session. The return type is a zone offset (a type of character in the format ' [+ |]) TZH:TZM') name or of a region of time zone , depending on how the user has specified the session time zone value in the most recent ALTER SESSION statement.
  
  Thank you.

  I think you enjoy now from [https://forums.oracle.com/forums/thread.jspa?threadID=2331231&tstart=0 url] your other thread that's not possible because one '+ n: 00' offset corresponds to time zones?

• SELECT * FROM DUAL-> Can this statement to make the quick health check?

  We have a product that will "SELECT * FROM DUAL" every 5 minutes. If there is no response, it sends an incident.
  
  My question is:-
  
  DUAL is a magic table in Oracle. So, without access to an actual table in oracle, can we take out of this statement
  before report us any problem on a database? In other words, this statement could be successful, but what are the chances
  that a query on a real table can fail due to limited resources?
  
  Thank you

• Why a function in a SELECT FROM DUAL is faster?

  (1) I have a SELECT with a function. Ex:
  "SELECT DISTINCT function (...) TABLE.
  
  (2) I've changed to SELECT it and to put the function inside a subselect with FROM DUAL. Ex:
  "SELECT DISTINCT (SELECT function (...) Table (FROM DUAL).
  
  (3) the second SELECTION is faster than the first.
  
  I discovered this problem on my paintings and my duties. I therefore made a generic example for this forum with a common function and large table. My results:
  Table has 2.196.058 records and the field is a VARCHAR2:
  SELECT DISTINCT SUBSTR(field, 2) FROM Table-> Executed in 110 seconds
  SELECT DISTINCT (SELECT SUBSTR(field, 2) FROM DUAL) FROM Table-> Executed in 39 seconds
  
  Why «SELECT DISTINCT (SELECT function (...)» Table (FROM DUAL) "is faster than «SELECT DISTINCT function (...)» TABLE.
  
  
  Thank you

  Dang, forum software is buggy course today

  I'm sorry, I'm more confused!

  Oops, now we don't want that to happen!

  OK, back to the original question: "why call a function of a scalar subquery faster?
  Answer: because the function can come from the cache and reused instead of the function running again.

  I found this explanation step by step, which should make it clear (and it has substantially the same as what I had in mind to put in place as a test of the case later tonight), take a few minutes to read this one as well:

  http://www.oratechinfo.co.UK/scalar_subqueries.html

  When you compare the unit tests for your own testcase, it is clear that:
  -using the fractions of a second to test the scalar subquery caching will give you many different results.
  -all your table column values are distinct
  Oracle knows that it is not possible to reuse a result of cache here function, given that all the results will vary and so it will re - run your function in your query for each record in your table, no caching of scalar subquery cannot be expelled.

  Hopefully this will clear your doubts for good now ;)

  About step 7 and 8: No 11.2 for me available (yet), so I can't say anything about this, sorry about that.

  Edit

  In addition, one of your previous answers was:

  When I use a function within the SELECTION, I have a SCALAR subquery caching.

  Now, this is not 100% true.
  Depends (as always), you can have it, you will not, depends on the data allowing Oracle to reuse the results of the function of cache.

• How to add users from a different domain?

  I have 3 ESXi hosts and a server vCenter on "area A". I have a separate domain, 'area B' set up with a confidence of 2-way "area A".

  How can I add users 'domain' B to vCenter server on 'area A' so that they can connect? When I go to add permissions in vCenter, I can select appear 'area B' but not the users in the list and I can't manually, type in a 'domain' user B and add it. But I can add users from domain A, since the hosts and vCenter server on this domain.

  I don't know if it's important, but the approval of 2 lanes between these areas is not a transitive trust relationship.

  Thank you in advance for any help you can offer.

  Create a group in domain B, add users to this group. Create a group in domain A, and then add the domain group B. Now assign the Group of features in vSphere. You could use the built-in course examples or create new ones.

• Can I broadcast a preview issue to select users?

  I was wondering if there is a way for me to distribute a number of an extract from a publication of DPS to select users.

  What would be the process? I have a business account, but are not yet passed through the Apple App Store review process.

  UDID limit is 100. Restricted users preview problem is otherwise not possible with DPS Pro edition. If you're worried about folio integrated download fees, to build a single publishing application and publish it as a separate application.

  Try using the name of the table.

  Or you can use a table alias.

• Selected values from Shuttle

  I know there is a lot of discussion on the values of the shuttle and how to get the data to display on the right side, based on calculations. That makes sense, and I have this job. However, it works when I want to on the right side of the values that are not currently in the database? Here's my function, PLSQL, I thought I could try, but it shows nothing. Thank you.

  I thought that since the: P251_NAME value does not exist in the same table shuttle LOV, pulling double might work, but I don't get anything to work. Any help is appreciated.
  
  Jon

  Hi John,.

  If I read you correctly, you have, say, an element of shuttle based on "SELECT ENAME, EMPNO FROM EMP r BY 1 D". The value of must be based on a string delimited by two points values EMPNO and you don't have these values available on any table? But these documents are available in the P251_NAME article?

  If so, the only thing you need is to make sure that this string of P251_NAME of the EMPNO values delimited by a colon.

  Is this good? If not, could you explain more (perhaps using the select above as a guide)

• The MGP Apply mode / 'write' for the selected users?

  Is there a work around to implement the mode of MGP Apply / 'write' for the selected users? The reason is that we have registered who transact only the request online. In this case, they don't need to synchronize. Manually change the ALL_CLIENT$ CAN. OUTQUEUE_DIRTY to ' has only a temporary effect and would normally return to 'Y' after a user made another transaction online. Please advice.

  If you have users who just order updates, then why do need to be put in place in the mobile app? they still appear in synchronization history? If this isn't the case, then I suggest that you just drop them from the mobile server because they have no need for the application lite oracle, just access to the server application.

  Regarding updates to direct data to the tables of mobile repository then (although not recommended), normally they don't cause problems, but would bypass in some cases associated with the transformation.

  If you change the param_value in c$ all_subscription_parameters, then the new setting of subsetting to take effect. However, if you do the same action via mobile manager, it also triggers a reset (if used) customer zero, assignment of new values in sequence and re-evaluation of the list of items of publication associated with c$ all_client_items - these products of two change would be lost if you just update the data in the table

• prevent users from deleting any other data

  I have a table
  
  create table T)
  infoID number primary key,
  Info varchar2 (4000).
  user varchar2 (1)
  );
  
  and users a, b, c with privileges of object on table T.
  
  What is the best way to prevent users from deleting any other data?
  
  1. create a view for each user to interacat with (where user = 'a') and to revoke the privileges of table T.
  2. use the procedures or trigers to catch a bad user.
  3.

  you will have 1 table T shared between 3 users a, b and c and the need of the user a power manage only his own lines (manage is meaning insert/update/delete/select)

  so the solution could be seen with trigger 'instead of', but Oracle has developed functionality especially for this DTV: [virtual private database | http://download.oracle.com/docs/cd/B28359_01/network.111/b28529/intro.htm#i1010494 |] VPD]
