• Rewrite the query with joins, and group by

  Hello
  
  It's an interview question.
  
  Table names: bookshelf_checkout
  virtual library
  
  And the join condition between these two tables is title
  
  We need to rewrite under request without using the join condition and group by clause?
  
  

  SELECT b.title,max(bc.returned_date - bc.checkout_date) "Most Days Out"
             FROM bookshelf_checkout bc,bookshelf b
             WHERE bc.title(+)=b.title
             GROUP BY b.title;

  When I was in College, I read most of SELECT statements can be replaced by operations base SQL (DEFINE the OPERATORS). Now, I am rewriting the query with SET operators, but not able to get the exact result.
  
  Kindly help me on this.
  
  Thank you

  Maybe it's not possible because it depends on your data.

  If the combination of all columns except END_TIME is not unique then there will be multiple records; a record for each unique combination (GROUP BY) of all other columns.

  The only way to ensure that a record is

  SELECT MAX(END_TIME) FROM myTable

• Help on report with max and group of?

  Hello I need to display the next report
  
  SELECT THE TABLE TABLE_NAME, NOM_PARTITION, LAST_ANALYZED IN USER_TAB_PARTITIONS;
  However, I need to display the table table_name time with sound (partition_name) MAX current (assuming that the names are P2010, P2011, etc...) and when he was last_analyzed
  
  What is the most effective way to do it? Subselect statement? Inner join?
  
  Thank you!

  Hello

  Using a GROUP BY:

  SELECT table_name,
         max(partition_name) as partition_name,
         max(last_analyzed) keep (dense_rank last order by partition_name) as last_analyzed
  FROM all_tab_partitions
  GROUP BY table_name
  ;
  

  Another solution would be a TOP - n query, using the ROW_NUMBER analytic function:

  SELECT table_name, partition_name, last_analyzed
  FROM (
    SELECT table_name,
           partition_name,
           last_analyzed ,
           row_number() over( partition by table_name
                              order by nlssort(partition_name,'NLS_SORT=BINARY') desc ) as rn
    FROM all_tab_partitions
  )
  WHERE rn = 1
  ;
  

  Note that I had to use the NLSSORT function to get the same result as the value that the query GROUP BY.
  Depending on your NLS DB/SESSION settings, you may not do.

• Cases and Group by

  I tried to understand what is the problem with a large sql query that does not change what I do.
  Have managed to isolate the part which is a failure, but I get the error message:
  
  ORA-00979: not a GROUP BY expression
  
  is not very useful.
  
  I suspect there is something fundamentally wrong in what I'm trying to do.
  
  I had to anonimise the names of the tables and fields that the data that I use is quite sensitive, but it should not forget the problem.
  
  Here is the query:
  

  select
  case when a='100' and cost in (select cost from lookup) then '100' else b end as main,
  count(*)
  from 
  data_table
  group by 
  case when a='100' and cost in (select cost from lookup) then '100' else b end

  DATA_TABLE has (among others) of fields:
  a, b, and the cost
  
  search contains the field:
  cost
  
  All fields are VARCHAR2 (255)
  
  
  If I remove the count (*) and any group of the query statement runs it is to say:

  select
  case when a='100' and cost in (select cost from lookup) then '100' else b end as main
  from 
  data_table

  This shows that the stated case is valid - then why I can not combine the count and group of?
  If this is a reason of syntax is there another solution that I can possibly use subqueries to work around the problem - I prefer to avoid this and can't really make the case in a decoding without him make mess.

  Oracle Database 10g Enterprise Edition Release 10.2.0.3.

  Published by: user8378443 on May 11, 2011 10:26

  Try like this,

  SELECT MAIN, COUNT (*)
    FROM (SELECT CASE
                    WHEN A = '100'
                     AND COST IN (SELECT COST FROM lookup)
                    THEN '100' ELSE b
                 END
                    AS MAIN
            FROM data_table)
  GROUP BY MAIN

• Need a clarification on the concept of 'World' and 'Group' with regard to CPU reviews

  All-

  I am investigating questions of CPU usage for one of my guests with esxtop. Can someone clarify the concept of 'World' and 'group '? Many of my guests have a 7 or 11 NWLD and I'm trying to figure out exactly this means. What I gather is the following:

  A guest has many worlds

  There is one guest per group

  A group contains many worlds

  Can someone also explain the purpose to describe the use of the processor in this way?

• How can I restore my tabs and groups of tabs after a update to version 36.0?

  I work with many tabs when I use Firefox. I keep classified in groups of tabs, which helps to separate the different children to work I do and interests I have. I have been using this environment for years. When I started my job today, Firefox updated to v36.0, and noted the following behaviors:

  1. There is only one group of tabs when you try to display tabs at Panorama, as opposed to a dozen groups;

  2. normally if the hidden tabs (tabs in the same group as the startup group, and not the default page) downloading of content to what the user clicks on, icon, if any, and the name of the page will show on the tab currently, the tabs display 'New tab' and no icon. It seems, however, the number of tabs that exist across all groups of tabs, but are now ghosts this default value, a group of tabs. I must add, however, I do not count the number of tabs, so I can't be exactly. When you click on it, there is just a blank page. It is so strange that Firefox knows they are there but cannot simply attach the address.

  I tried to restore the following files from my backup of Windows Home Server to the folder AppData\Roaming\Mozilla\Firefox\Profiles\ .default < gobbletygook >:

  1. in the sessionstore-backups folder, I replaced the files previous.js, recovery.bak and recovery.js (not all of the upgrade ~) with the files yesterday and the day before yesterday.

  When that did nothing, I replaced

  2 sessionCheckpoints.json

  I do not see any file with a recent date that seems to be the one that I have to restore. I should add that I don't see hidden files. I thought about the restoration of the whole of the batch, but didn't know how it would affect the program v36.0 and the profile on 35.0.1 files.

  I have deadlines this week and must immediately restore my environment in order to make these possible. I have no address list on my Web pages to work in IE or other. Any help would be much appreciated.

  On a second note, I had been wondering recently if this tab group environment is an appropriate way to maintain my work environment. Sometimes, during the opening of Panorama, I would get an error saying a script takes too much time, but if I clicked on continue, it would display the groups in a few seconds. I considered bringing it in bookmarks, but it would be tedious and more difficult to access and open several tabs. Initially, I tried tabs groups thinking it was just a matter of maintaining a table of addresses (in tabs) with a name or an ID of tab group. How that might go wrong? Well, there, so it is obviously more complicated than that, and I did not know that upgrades would affect the data of a personal nature. That I should abandon the use of tab groups?

  With the help of information from the user, ptressel, in a post here on the existence of sessionstore.js when version 33 was released, I could easily get my tabs and groups of tabs as follows:

  1. close Firefox and, perhaps, wait a few seconds (30 years?) for any final closing of files;
  2. Check if you have a sessionstore.js file in your profile folder, named as I documented in my original post above.
  3. If this is not timestamped before the discovery of your problem, open the sessionstore-backups folder.
  4. Check if the recovery.js file is properly stamped and, if not, the recovery.bak.
  5. At this point, you are likely to find that none of them is before your problem occurring. If so, open your backups from this folder and go through steps 2 to 4 to find a file before your problem occurring.
  6. When you find a file, copy it to the root of your current profile folder and name it, "sessionstore.js.
  7. Open Firefox. Mine opened upwards as you wish.

  It is a solution for Windows. Sorry I can't comment on other platforms, but I'd bet it's just a copy of file and change of name, it is likely even.

  For Windows users, you can find you must sign out and sign in as administrator in order to access backups. You must not logoff your standard account, but do have Firefox closed as described above.

  Hope that helps.

  Concerning

• A query containing a subquery and Group By all-in-one

  Hi people,
  Any interesting fact but nerve racking situation I have here. I have a question that I have to do counts and amounts and I also need to have a Sub inside query. When I run my application, I get an error like this:
  
  Error in the command line column: 4:36
  Error report:
  SQL error: ORA-00979: not a GROUP BY expression
  00979 00000 - "not a GROUP BY expression"
  * Cause:
  * Action:
  
  Here's my query:
  

  select distinct to_char(c.start_date,'YYYY') start_date,
           substr(acc.account_num,1,12) account_number,
         ( select acc2.account_desc from student_account  acc2
           where  acc2.account_num = acc.account_num 
           and    acc2.account_type = 'A'
         ),
         COUNT(distinct(s.student_id))
  from student s,
         student_account acc,
         course   c
  where s.course_id = c.course_id
  and     s.account_num = acc.account_num
  and    to_char(c.start_date, 'YYYY/MM/DD') between '2004/01/01' and '2009/12/31'
  group by to_char(c.start_date,'YYYY'), substr(acc.account_num,1,12)
  order by 1;

  If I replace it with the acc.account_num (subquery) with a number that is in the database, then my request works well.

  Hello

  We don't know what you want. It would really help if you posted some examples of data (CREATE TABLE and INSERT statements) and the results desired from these data.

  Are you sure that the scalar subquery will return ever more than one line? If so, you can wrap in a MIN or MAX aggregate function, as I've suggested before:

   select distinct to_char(c.start_date,'YYYY') start_date,
           substr(acc.account_num,1,12) account_number,
     MIN ( ( select acc2.account_desc from student_account  acc2     -- Changed
           where  acc2.account_num = acc.account_num
           and    acc2.account_type = 'A'
         ) ),                                   -- Changed
         COUNT(distinct(s.student_id))
  from student s,
         student_account acc,
         course   c
  where s.course_id = c.course_id
  and     s.account_num = acc.account_num
  and    to_char(c.start_date, 'YYYY/MM/DD') between '2004/01/01' and '2009/12/31'
  group by to_char(c.start_date,'YYYY'), substr(acc.acct_acc_num,1,12)
  order by 1;
  

  It seems that you could also simplify the query and make more fast, eliminating the scalar subquery. The table there is already part of the main query, you can do something like this:

  SELECT    TO_CHAR (c.start_date, 'YYYY')     AS start_date
  ,         SUBSTR (acc.account_num, 1, 12)      AS account_number
  ,       MIN ( CASE
                      WHEN  acc.account_type = 'A'
                THEN  account_desc
                  END
             )                         AS a_desc
  ,         COUNT (DISTINCT s.student_id)          AS student_id_cnt
  FROM       student            s
  ,       student_account     acc
  ,       course          c
  WHERE       s.course_id          = c.course_id
  AND       s.account_num          = acc.account_num
  AND       c.start_date          BETWEEN DATE '2004-01-01'
                        AND     DATE '2009-12-31'
  GROUP BY  TO_CHAR (c.start_date, 'YYYY')
  ,            SUBSTR (acc.acct_acc_num, 1, 12)
  ORDER BY  start_date;
  

  I guess that course.start_date is a DATE. Instead of converting each start_date to string (so you can see if it is in the right range), it is more efficient and less prone to error, compared to other DATEs, as shown above.

  It is very strange that you

  substr(acc.account_num,1,12)
  

  in the select clause, but

  substr(acc.acct_acc_num,1,12)
  

  in the GROUP BY clause. Did you mean having the same column in both places?

  Yet once, without seeing some examples of data (CREATE TABLE and INSERT statements) and the results desired from this data, I can't do much.

• Combine in a single line: check the box Case() and Group BY

  Hello
  
  I have a little problem and it seems my knowledge and possession is simply not enough good to slove it.
  
  To better understand my question here an example (the actual query is too large):
  Data:
  NAME, CASE_NO, GO_TAG
  Tom 10 GB
  Tom 15 GB
  Tom 20
  30 Tim
  Tim 40
  
  My query looks like this:
  SELECT NAME,
  CASE
  WHEN (GO_TAG IS NOT NULL) THEN wm_concat (CASE_NO)
  ANOTHER NULL
  END WITH_GO_TAG
  CASE
  When wm_concat (CASE_NO) (GO_TAG IS NULL) THEN
  ANOTHER NULL
  END WITHOUT_GO_TAG
  GROUP BY NAME, GO_TAG;
  
  
  Now what I get output:
  NAME, WITH_GO_TAG, WITHOUT_GO_TAG
  Tom, 10, 15', "
  Tom, ", '20'
  Tom, 10, 15', "
  Tom, cm, 30, 40'
  
  Here's my problem: I want a line instead of two lines for "Tom."
  It looks like: Tom, 10 ', 15', 20'
  
  Is this possible?
  
  You should know that I coded those SQL things to right directly in this forum to show you my problem... hope you can understand it :-)
  
  Hope someone can help me in this case.
  
  Oh, almost forgot, I (or better: my company) use Oracle Version: 10g
  
  See you soon,.
  Phil

  Hello

  Thank you. It's clearer.

  Did you count 5 lines of sample data, or 10?
  In SQL * Plus, when you finish an order with one; and then have a /, the / means "repeat the last command. So, when I run

  INSERT INTO EXAMPLE VALUES
  ('Tom', 10, 'go');
  / 
  

  I get 2 identical rows. I suppose you want only 1.

  When you say ' GROUP BY name, go_tag ', the output contains a line for each distinct combination of name and go_tag.
  If you want just one row for each distinct value of the name, just say 'GROUP BY name. If we are not group by go_tag, we must be careful that any reference to go_tag in the SELECT clause is like an aggregation function argument, like this:

  SELECT     NAME,
             STRAGG (NVL2 (go_tag, case_no, NULL))     AS with_go_tag,
             STRAGG (NVL2 (go_tag, NULL,    case_no))     AS without_go_tag
      FROM   EXAMPLE
  GROUP BY   NAME;
  

  NVL2 (a, x, y) is equivalent to
  CASES WHERE an IS NOT NULL THEN x ELSE y END to this problem, I found NVL2 easier than CASES to read and understand, but I don't maintain your code, then you should use your way of thinking is the best.

• Is it possible to save the current tabs and groups so that they can be recharged at any time?

  My Firefox crashes sometimes, and when I start it up again, my groups and tabs that I had are lost, so I need to recreate my history window. Is there a way I can save the groups that I have with the tabs on the inside so that I can retrieve them at a later date.
  "I say that Firefox does not save the whenever I close the browser, so I'm güssing there a file somewhere that contains this information, if I know how is called this file I could save it on my regular schedule and retrieve them if I had to, of course the best solution would be to have a ' save the groups ' & 'Support groups' in the menu.

  Thanks in advance

  (PIN) App tabs and groups of tabs (Panorama) are stored in session data in the sessionstore.js file in the Firefox profile folder.

  You can use this button to go to the Firefox profile folder currently in use:

• Research Protect deleted all my tabs and groups of Firefox

  I had about 200 tabs grouped together in about 30 groups of 31.0 Firefox (latest version). The Group appeared when I clicked on the icon to the left of the button "minimize" or press CTRL + SHIFT + E. It is called "your Firefox tabs - group". I also use Xmarks, but I have disabled Synchronization tab recently.

  Generally all the tabs and their groups have been saved when I closed Firefox. Today I opened Firefox and all tabs and groups disappeared! Instead, it opens some search engine called Trovi (www.trovi.com) with "bing results. Its the same in Chrome, Opera and IE.

  My OS is Windows 8.1 update 1 with all updates installed. My antivirus is Avast! with all updates installed. There was some malware installed of course, but I'm not awake me. I ran a 'full system test' in Avast! latest updates, which is the deeper analysis that I know (without my laptop HP ProBook 4730 s restaring). No viruses were found.

  I'm suspecting a program called 'Research Protect' version 2.16.10.61 'Client Connect Ltd. It was installed with PowerISO 6.0 x 64.

  I tried to run the system restore, but it seems that all the restore points I ever created are now deleted! I discovered this by opening the system properties-> system-> system restore Protection. However, 'Protection' is 'On' for my system disk.

  How can I restore my tabs and groups? It is extremely important for me.

  Accidentally, I posted my question twice - my apologies. I marked this as resolved and will continue to ask for help on the other.
