• Update col value based on an another tbl - update, case stmt, subquery

  I need to

  Use ALTER TABLE.

  (2) the value of col1 will be updated to the value of column col2 from table tbl2.
  (3) if the tbl2 returns the number of records or no records, the value of col1 will default to 0. otherwise, it will be the unique value of col2 of tbl2

  Use an expression BOX to test if there is a line matching or not and return a value on this basis.
  For example:

  UPDATE  tbl1     t1
  SET     col1     = (
              SELECT  CASE
                      WHEN  COUNT (*) = 1
                      THEN  MIN (col2)
                      ELSE  0
                    END
              FROM       tbl2
              WHERE       common_column_1     = t1.common_column_1
              AND       common_column_2     = t1.common_column_2
              )
  ;
  

  Because the subquery uses an aggregate function (COUNTY), the returned value must be as an aggregate (such as MIN) or a constant (such as 0). In cases where there is only 1 row, we could use MAX, AVG or SUM instead of MIN to get the value of this one line.

• How to make a sum of a subquery which first determine the time period and then the total sum.

  Hello

  I know how to solve it in two of the query, but I want to merge this in a single query.

  I have records in a table with the status 1. I also have records in the table with the State 2 and 3. But the 2 and 3 folders can have a period different kind of these must be determined in advance when this is, mind a deviding through 3 or 12 months.

• 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.

• A subquery within the instruction BOX

  I try to use a subquery in a Case statement with a condition 'where' that binds at the request of the mother. Like this:
  

  Select T.idperson , CASE WHEN  T.type = 'C' THEN (SELECT name from Customers where C.idcustomer = T.idperson) 
  ELSE
   (SELECT name from Providers where idprovider = T.idperson)
   END Name 
  from myTable T 

  It works for me in SQL Server, but in ORACLE the subquery does not return line, I guess that it is binding to the parent query part. All thoughts in another way, I could get the result I want?
  
  Thank you
  
  JuanDiego

  Hi, Juandiego,

  If it's not returns all rows, you must have all the lines in the table.
  If you have lines in the table, you either get
  (a) an error or
  (b) some lines (even if the columns are set to NULL).

  There is another way to get the desired results.
  I probably wouldn't use scalar subqueries. I'd do it outer join all the tables, like this:

  Select  T.idperson
  ,       CASE
              WHEN  T.type = 'C'
              THEN  c.name
              ELSE  p.name
          END  AS Name
  from             myTable   t
  LEFT OUTER JOIN  Customers c  ON c.idcustomer = T.idperson
  LEFT OUTER JOIN  Providers p  ON p.idprovider = T.idperson
  ;
  

• How can I get rid of the top of the case. offers4u and "go around the web" pop-up windows and unwanted when links pop up windows is already turned off on my laptop

  I tried this software ad/malware and tried the launchdaemon corrections responsible extensions suggested and still can't find where they are hiding on my computer.  One of them adds unwanted links with green circular arrows on other Web pages and advertising windows with offers for similar products pop - up on Safari and Chrome.  They are driving me crazy, I even paid for the software adblocking, which serves to block the sites I want to open and still allows popups!

  You may have installed ad-injecting malicious software ("adware").

  Do not use any type of product, "anti-virus" or "anti-malware" on a Mac. It is never necessary for her, and relying on it for protection makes you more vulnerable to attacks, not less.

  Save all data first.

  Some of the most common types of adware can be removed by following the instructions from Apple. But before you follow these instructions, you can try an automatic removal.

  If you are not already running the latest version of Mac OS X ("El Capitan"), update or upgrade in the App Store you could adware to automatically remove. If you are already using the latest version of El Capitan, you can still download the current update of the Apple Support downloads page and run it. Still, some types of malware will be deleted, not all. There is no such thing as the automatic removal of all possible malware, either by OS X third party software. That's why you can't rely on software to protect you.

  If the malware is deleted in your case, you will still need to make changes to the way you use your computer to protect you from new attacks. Ask if you need advice.

  If the malware is not automatically deleted, and you cannot remove yourself by following the instructions from Apple, see below.

  This simple procedure to detect any type of adware that I know. Disabling is a procedure distinct and better still.

  Some legitimate software is funded by advertising and may display advertisements in its own windows or in a web browser while it is running. It's not malware and it may not appear. In addition, some Web sites display advertising intrusive popup that can be confused with adware.

  If none of your web browsers work well enough to carry out these instructions, restart the computer in safe mode. Allows to temporarily disable the malware.

  Step 1

  Please triple - click on the line below on this page to select it, and then copy the text to the Clipboard by pressing Control-C key combination:

  ~/Library/LaunchAgents

  In the Finder, select

  Go ▹ go to the folder...

  from the menu bar and paste it into the box that opens by pressing command + v press return. Open a folder named "LaunchAgents", or you will get a notice stating that the file cannot be found. If the file is not found, proceed to the next step.

  If the folder opens, press the combination of keys command-2 to select the display of the list, if it is not already selected. Please don't skip this step.

  There should be a column in the update Finder window. Click this title two times to sort the content by date with the most recent at the top. If necessary, enlarge the window so that all the content show.

  Follow the instructions in this support article under the heading "take a screenshot of a window." An image file with a name starting in 'Screenshot' should be saved to the desktop. Open the capture screen and make sure it is readable. If this isn't the case, capture a small part of the screen indicating that what needs to be shown.

  Start a reply to this message. Drag the image file in the editing window downloading. Alternatively, you can include text in the response.

  Leave the case open for now.

  Step 2

  Do as in step 1 with this line:

  /Library/LaunchAgents

  The record which can open up will have the same name but is not the same as in step 1. In this step, the folder does not exist.

  Step 3

  Repeat with this line:

  /Library/LaunchDaemons

  This time the file will be called "LaunchDaemons."

  Step 4

  Open Safari preferences window and select the tab 'Extensions'. If the extensions are listed, post a screenshot. If there are no extensions, or if you cannot launch Safari, skip this step.

  Step 5

  If you use Firefox or Chrome browser, open the list of extensions and do as in step 4.

• Satellite 1800-514: need parts such as keyboard, screen, inverter

  I have a portable Satellite 1800-514, I need to get some parts of second hand for this that I have a few internet size for parts, but I need to know what other laptop I can take parts to repair it.
  These are the parts that I need of keyboard, screen, inverter and the front of the case where the screen is.

  Hello

  If you are looking for second hand parts then I would recommend the search on Ebay for a Satellite 1800-514 of second-hand sites.
  Especially a full section of second hand is much less expensive than individual parts and devices!

  In my opinion, you can use the entire Satellite 1800 series parts.
  The screen, keyboard, FL inverter and the screen frame must be the same.

  In addition, if you want you can contact Toshiba service provider in your country.
  Guys might provide a list of compatible parts and devices

  Why is this code not work and it is possible to use a case statement in a Page Apex process

  Of course, it is possible to use a CASE statement or expression (it is the latter) in a page APEX process. However, it is not possible to use an invalid syntax while doing so. Part of a clause INSERT INTO can contain only static column names.

  In general the SQL expressions (and also the bind variable, another cause frequent errors of syntax) can be used only in

  • the projections of the SELECT queries and subqueries
  • the right side of the disposals in the SET update clause
  • the lists of VALUES of INSERTs
  • WHERE clause predicates

  Or you could UNPIVOT 3 dates on 3 different ranks first and then use only 1 CASE expression.  I find the above path.

• Dynamic Case expression

  select  count(*)
    from  vwsr_all_merged_data s
   where  sr_tio_priority in ('Level 0','CEO','TER','Priority Assistance','Enquiry')

  the same should be able to dynamically with a Case expression, until I create the string as
  

  SELECT

• Problem with CASE statements

  Hi all
  
  I have a calculation in a report of Discoverer Desktop with 29 instructions BOX and still 2 case statements more to add. The problem is that my report freezes and fails to run due to the excessive number of case statements. I need to put the 31 statemnts cases in the report, how do I do this? Is there another way to do it without causing the report to freeze?
  
  Below is part of my instructions box just to show you what I'm doing:
  
  CASE WHEN Ex = 'MM' AND THEN of OTHER NULL result (', ')
  CASES WHERE Ex = "PP" AND result IN (40,35,30,25) THEN NULL OTHERWISE
  CASE WHEN Ex = he's ' AND result IN (' a ',' B', 'C', d ') THEN NULL OTHERWISE
  -CASE WHEN Ex = 'IO' AND THEN of OTHER NULL result ('Distinction', 'Merit')
  -CASE WHEN Ex IN ('ZZ', 'WW', 'SS', 'KK') AND ('PASS', 'P') THEN to ANOTHER NULL result...
  
  The last statement should be BOX WHEN... THEN NULL OTHERWISE 1 END END END END...
  
  Help, please. Thank you.

  Hello
  You have reached the limit of characters in a calculation.

  Try to set into a single statement as follows:

  CASE WHEN Ex = 'MM' AND THEN of OTHER NULL result (', ')
  WHEN Ex = "PP" AND as a result (40,35,30,25) THEN NULL OTHERWISE
  WHEN Ex = he's ' AND result IN (' a ',' B', 'C', d ') THEN NULL OTHERWISE
  WHEN Ex = 'IO' AND THEN of OTHER NULL result ('Distinction', 'Merit')
  WHEN Ex IN ('ZZ', 'WW', 'SS', 'KK') AND ('PASS', 'P') THEN to ANOTHER NULL result...

  The last statement should be BOX WHEN... THEN NULL OTHERWISE 1 END

  Another option is to combine all the statements of NULL in a series of gold options like this:

  BOX WHEN
  (Ex = 'MM' AND the result in (', am')) OR
  (Ex = "PP" AND result IN (40,35,30,25)) OR
  (Ex = he's ' AND translated BY (' a ',' B', 'C', ')) OR
  (Ex = 'IO' AND as a result ('Distinction', "according to merit")) OR
  (Ex IN ("ZZ", "WW", "SS", "KK") AND result IN ('PASS', 'P')) THEN ANOTHER NULL...

• case on a column

  Hi all
  
  
  I have a table:

  ...
  VALE_1            VARCHAR2(1) DEFAULT 'S',
       VALE_2            VARCHAR2(1) DEFAULT 'S',
       VALE_3            VARCHAR2(1) DEFAULT 'S',
       VALE_4            VARCHAR2(1) DEFAULT 'S',
       VALE_5            VARCHAR2(1) DEFAULT 'S',
       VALE_6            VARCHAR2(1) DEFAULT 'S',
       VALE_7            VARCHAR2(1) DEFAULT 'S',
       VALE_8            VARCHAR2(1) DEFAULT 'S',
       VALE_9            VARCHAR2(1) DEFAULT 'S',
       VALE_10           VARCHAR2(1) DEFAULT 'S',
       VALE_11           VARCHAR2(1) DEFAULT 'S',
       VALE_12           VARCHAR2(1) DEFAULT 'S',

  where the columns VALE_1 to VALE_12 represent the months
  
  How can I create a case in one where, according to the month that I give I can check the column for this month (VALE_month) and thus get or not to get these lines?
  
  I'll try to explain better:
  
  "for example, for a given DATE = 10/01/2012 (10 months, that means October), I create a simple query to only check the VALE_10 column and can have the line if its value is of."
  
  Select * from
  
  "Check if the VALE_10 column = s"
  
  I hope that I was clear
  
  Thanks in advance

  Thanks for your time.

  Very true, but she, the table, or up to 12 lines, because each row (transaction) can have 12 values (VALE_XX): has / for each month

  (number of rows * 12)

  It's true, then create a new table, fill it with 12 times the number of lines that are in your original table, and then move the columns from the original table.
  If you cannot change the original table, you can create a view, which standardizes the columns:

  CREATE OR REPLACE VIEW     notmalized_x
  AS
  WITH   cntr               AS
  (
       SELECT     LEVEL     AS month_num
       FROM     dual
       CONNECT BY     LEVEL     <= 12
  )
  SELECT     x.primary_key
  ,     c.month_num
  ,     CASE  c.month_num
           WHEN  1  THEN  x.vale_1
           WHEN  2  THEN  x.vale_2
           ...
           WHEN 12  THEN x.vale_12
       END          AS vale
  FROM         table_x  x
  CROSS JOIN     cntr      c
  ;
  

  You will notice that the CASE expression in the view is very similar to the CASE expression that Solomon has suggested.
  Then, you will be able to do ion of simple queries of life, like this:

  SELECT     primary_key
  FROM     normalized_x
  WHERE     month_num     = EXTRACT (MONTH FROM SYSDATE)
  AND     vale          = 'S'
  ;
  

  If you don't want to create a view, you can do normalized_x a subquery.

  Thank you guys. This has been useful.

  I understand what Solomon did, but I'm confused when I need to run the full query. How to do this?

  I do a query online when I have to pull additional fields.

  You need a subquery to reference the alias finalnumbers.
  Do everything except the test for finalnumbers (and cklause ORDER, of course) in the subquery. view online, such as used Salomon or a WITH clause that:

  WITH  got_finalnumbers  AS
  (
   SELECT 'AA' Ledger, CASE WHEN a.GBCO='00001' THEN 'C86001' ELSE 'C' || Trim(a.GBCO) END Company,

• Poor implementation of "box, when then else"?

  It seems to me that my expression < next > is executed even if < WHEN > is false. I have a queury with LISTAGG, and if there are too many people, the string exceeds the limit of 4000 characters. I tried to use "BOX WHEN" to give a message instead of the list of names, but I always get an error.
  
  I have reproduced this with the HR schema. (A simple example ;))
  
  This was my first expression:

  SELECT department_id
  ,LISTAGG('Employee_ID: '||EMPLOYEE_ID ||' Name: '||FIRST_NAME ||' '||LAST_NAME ||' Email: '||EMAIL||' Phone number: '||PHONE_NUMBER||'Hiredate: '||HIRE_DATE, ',') WITHIN GROUP (ORDER BY hire_date) AS Employees
  FROM employees e
  GROUP  BY department_id;

  throw this error:

  ORA-01489: resultatet av strengsammenkjeding er for langt
  01489. 00000 -  "result of string concatenation is too long"
  *Cause:    String concatenation result is more than the maximum size.
  *Action:   Make sure that the result is less than the maximum size.

  With this expression I do not exceed the limit of 4000 characters and the message "too many employees" are correctly displayed.

  SELECT department_id
  ,CASE WHEN ((select count(*) from employees where department_id=e.department_id) < 30)
  THEN (LISTAGG('Employee_ID: '||EMPLOYEE_ID ||' Name: '||FIRST_NAME ||' '||LAST_NAME ||' Email: '||EMAIL||' Phone number: '||PHONE_NUMBER, ',') WITHIN GROUP (ORDER BY hire_date))
  ELSE 'Too many employees'
  END AS Employees
  FROM employees e
  GROUP  BY department_id;

  For this Department 50 expression exceeds the limit of 4000 characters, and I get the above error. But the 50 Department has 45 employees and should not be the same in the part 'THEN'
  

  SELECT department_id
  ,CASE WHEN ((select count(*) from employees where department_id=e.department_id) < 30)
  THEN (LISTAGG('Employee_ID: '||EMPLOYEE_ID ||' Name: '||FIRST_NAME ||' '||LAST_NAME ||' Email: '||EMAIL||' Phone number: '||PHONE_NUMBER||'Hiredate: '||HIRE_DATE, ',') WITHIN GROUP (ORDER BY hire_date))
  ELSE 'Too many employees'
  END AS Employees
  FROM employees e
  GROUP  BY department_id;

  Oracle is a very silly implementation of ' BOX WHEN.. "or I do something wrong?
  
  I can solve this another way?
  
  Kind regards
  Thomas

  A way out could be

  SQL> SELECT department_id, SUBSTR (NVL (listagg (str, ',') WITHIN GROUP (ORDER BY hire_date), 'Too many employees'), 1, 20) || ' ... ' employee
      FROM (SELECT department_id,
                   hire_date,
                   CASE
                      WHEN COUNT (*) OVER (PARTITION BY department_id) <= 30
                      THEN
                            'Employee_ID: '
                         || employee_id
                         || ' Name: '
