• Problem with the case where the clause

  Hello

  I want to use cases in which clause. I wrote a very simple query to test how it works. However, I always got an error message. Here's what I did.

  Hi, Jennifer.

  Why do you want to use BOX in a WHERE clause?  The wonderful thing about the CASE is that it allows you to do IF-THEN-ELSE logic.  In a SELECT clause, or an ORDER BY clause, this is really useful, but the WHERE clause already allows you to use the IF-THEN-ELSE logic.

  However, if you use the BOX in a WHERE clause, it is as it does nowhere else.  Always BARGAIN instead of a single expression in a SQL data types.  All the clauses THEN (and ELSE, if there is one) must return a single expression, such as the NUMBER.  (There is no BOOLEAN data type in SQL).  So, you can use a CASE statement like this:

  ...

  CASES WHERE

  WHEN 1 = 1 THEN 1

  WHEN 1! = 1 THEN 2

  END = eid

  Here, the CASE expression takes the place of a NUMBER.

  However, if I was not sure if 1 = 1 or not, I would write the condition in this way, without a CASE expression:

  WHERE (1 = 1 AND eid = 1)

  OR (1! = 1 AND eid = 2).

  You cannot use the CASE statement like this. Change your where clause like this.

  WHERE (
       (v_count = 0 and pe.estimatestatusid != 3) or
       (v_count != 0 and pe.projectestimateid IN (1, 2, 3)

• Cases where the undo data generated

  Other than the DML activities, what are the other cancellations of cases generated?

  Most of the DDL statements are translated into some update database dictionary (which means DML to tables SYS) and/or DML on the application tables: so DOF also generates Cancel.

• using members of the cast with the case of the declaration

  Hi guys,.
  
  can someone guide me how to use a "case _ of" with the members of the cast rather than sprites?

  OK, I see. You can use the case statement and replace the
  Manager executeBranchingMenu for this example.

  ------------------------------------------------------
  on executeBranchingMenu NomMenu, commandName
  commandName case
  ("Item 1, 1"): go to frame "an image tag.
  ("Item 1, 2"): go to frame "a few other image tag.
  -etc.
  cases of termination
  end
  ---------------------------------------------------------

  But there is a solution even more simple that does not require using a case
  Statement at all. Your frame labels just name "Item 1, 1", "Item 1," 2",
  etc and use it. It will save you a lot of unnecessary code.

  ---------------------------------------------
  on executeBranchingMenu NomMenu, commandName
  go frame commandName
  end
  -----------------------------------------------

  Furthermore, nothing new in this example of a film that holds the game
  head back, then you probably want to add code to do this, otherwise, it will be
  jump to the menu. It can be added to the film script.

  --------------------
  on exitFrame
  go part
  end
  -------------------

• How can I control the working time so that the loop structure in the cases where the structure?

  Hi all

  My job is: Loop While structure generates the signal for 4 seconds when you press the 'start build' button, after that data has been backed up. You press the button "generate the beginning' once again, and the loop runs one again.

  My problem is: the first pressing, the loop, exactly 4 s (3, 999 s), but him second, third pressing on... The time elapsed is not 4 seconds, always smaller (even ~ s 0.003). The loop works correctly after press the "Exit" button and launch the program again.

  How can I control exactly time loop work While Structure without the press "Exit".

  Thank you any help!

  P/S: I used the number of cycles (ms) just to look at a working time of the While loop.

• Once again... Help... CASE in the WHERE clause...!

  Hi all
  
  I posted the question about CASES where the condition. It is one of the changes.
  
  The first condition was, if the Individual is 01 extraction then all the values of the table where the column of FLG = 'Y '. If the Individual is 02 and then extract all the values of the table where the column of FLG = ' no or NULL. Here, INDI is the setting.
  
  Select count (*) from cntl
  XYZ
  where NVL(FLG,'N') = decode(INDI,'01','Y','02','N');
  
  Now the chnages is, if the Individual is 01 and then extract all the values in the table where FLG colum = 'Y '. If the Individual is 02 and then extract all the values in the table, including ('Y', ' n, NULL). no need to put the filter of the FLG columns in which contion.

  It's not just...

  select count(*) into cntl
  from xyz
  where NVL(FLG,'N') = decode(INDI,'01','Y','02',NVL(FLG,'N'));
  

  Or shorter:

  select count(*) into cntl
  from xyz
  where NVL(FLG,'N') = decode(INDI,'01','Y',NVL(FLG,'N'));
  

  If you are happy for 01 retreat flg of Y and any other value fold everything.

• give meaning to cases where minimum effective_start_date is greater than the current date

  Hi guys, I'm not a developer oracle as such, but I'm trying to get some information from oracle to send to other systems of the company, since we are dealing with oracle HRMS as the master system for employee information.

  In particular, we would like to create people in our training and the security system when they are created in oracle.

  I was told that the oracle per_all_people_f object acts as a slowly changing dimension of type 2, where a person can have several versions, which only is always the current version and the current version can be retrieved using the standard parttern of "date of current between the effective start date and actual end date. So far so good.
  
  However, I can see there are cases where the minimum 'effective_start_date' is greater than the current date. It is, indeed, equal to their start_date. I guess start_date represents "the first day of work" of the person.

  But this means then there is no "current" information known to people who have not yet really started working for the company again. This seems odd. How can I have someone for whom we have no information "currently correct? I was told that the effective_start_date of the line is automatically set to their "first day of work" date on which the information is entered into the system, IE, the user to enter information doesn't have the ability to say 'this is the current version of the data for that person, who starts at a date in the future. "

  For this reason, I cannot know these new people (who have been entered in oracle, but did not have actually to their first day of work still) training system. But we would obviously get people established in related systems so that they can use all of these systems on their first day of work.

  Have I misunderstood something here? How can there be no correct version for a person at the date and time?

  Hello

  How normally "inform you" the training system on a new person record? If it's a kind of report or an interface, it may be useful changed to examine a number of days in the future, for example + 7

  It is important to understand when you look at an Oracle HRMS instance through enforcement (i.e. the ' front end'), you look at the data on a date date (of the session) - by default, the date is the system date, but it is possible for a user to change this date to be in the future or the past as they see fit. The ability to implement the records in person in the future is a great feature to have, of course, but it must be understood that in this situation, at the date of the day the person's file logically does not exist yet from the point of view of the MFC features. Behind the scenes, however, in the per_all_people_f of the table, the line exist. Similarly, future update of changes to a person (e.g. marital status from Single to married) could be implemented, and the change in status would be visible if the session has been scheduled on a date or after the date of the marriage. As correctly observe you, behind the scenes, the table will hold all historic entries for this person_id with contiguous effective_start_date and effective_end_date beaches.

  Either way, date_start value is not related to as such hiring date; It is actually the value of effective_start_date earlier for the person_id. All changes, regardless of how many or what the effective_start_date is in each case, will always carry this same start_date value. It * may * be identical to the hiring date (certainly the fact that you configure their hire date person records would cause that), but if the person has been created as a postulant effective from 1 September and was then hired has effect from 21 September, column start_date value would be still 1 September. The record of the person would be visible when the current date is on or after this date - the only difference is that they show that an employee until the 21st.

  I hope this helps, but it is possible, that I just confused you more!

• using the function to decode or case in query

  Hi experts
  
  I use the Oracle 11 G server, I need to check the length of the value in the name column of the table employee and if length (name) > 39 then the value should be substr (name, 0, 39)
  else value should be the name.
  I tried code below

   
  select CASE when length(name) > 39,substr(name,0,39)
              else name
         END
    from employee 

  but it's not working... can I do this using decode too? which one would be better or this is not a good way?

  Review the syntax of the CASE expression in the Manual of the SQL language. An expression BOX always at least a THEN clause. Commas are not part of the syntax of the CASE expression.

  can I do this using decode too?

  Of course, everything you can do with CASE, you can also do it with DECODE.

  that it would be better

  This is one of the many situations where the CASE is much shorter, clearer and more effective than DECODE.

  or is not a good way?

  What is

  SELECT  SUBSTR (name, 1, 39)  AS employee_name
  FROM    employee;
  

  ?
  If the name is 39 characters (or less), then SUBSTR (name, 1, 39) will ship itself, unchanged.

• decode in where the clues

  Hi I have the code what value of query of database, the use case is the user enter the value as 1,01,11 in the database, but when the user enters the value in the xml file may not enter 11,01,12 in the database there are two columns leave say column = 1 test1 and test2 = 2 combination of 12 which is the value of the use will be xml, but sometimes use can enter 04 = test1 test2 = 00 column how I approach this

  I called myself map with crdind, crdpos1, cardpos2 as the primary key of table column

  using can enter the value that

  crdind = 1

  crdpos1 = 5

  crdpos2 = 3

  inactivedate = 2013-05-24

  activedate = null

  another line

  crdind = 1

  crdpos1 = 5

  crdpos2 = 5

  inactivedate = 2013-05-24

  activedate = null

  another line

  crdind = 6

  crdpos1 = 02

  crdpos2 = 00

  inactivedate = 2013-05-24

  activedate = null

  the rule says that if you enter a number in the crdpos1 example 2 you must enter the value in crdpos2 it can be any number 1-9 but if you enter crdpos1 crdpos2 is 00 00-09

  the challenge I

  is to query this value after they entered

  I have the xml file that got crdpos of land use enter 15 which is the combination of colunm crdpos1 = 1 and crdpos2 = 5

  How do I hit the crdpos value and got and able to query in the database in two columns of storage

  something like

  Select inactivedate from the map

  where crdind = '1 ' ".

  and crdpos1 = '5'

  and crdpos2 = "3"

  but my problem is crdpos1 maybe 05 and crdpos2 00

  How can I have one where the clues that return values in both cases based on what the user enters

  am in oracle 11g release 2

  I posted the request as below:

  SELECT *.

  CARD

  WHERE crdpos1 = CASE WHEN: inp1 = '0' THEN: inp1. : ELSE inp2: inp1 END

  AND crdpos2 = CASE WHEN: inp1 = '0' THEN '00' ELSE: inp2.

  To run Java, replace all occurrences of the bind variables (: inp1,: inp2) with? in the above query example

  SELECT *.

  CARD

  WHERE crdpos1 = BOX WHEN? = '0' THEN? ? ON THE OTHER? END

  AND crdpos2 = BOX WHEN? = '0' THEN '00' ELSE? END;

  In Java, I guess you must be passing two values. If you the user enter '01', you will pass two values, one is '0', and other is 1' i.e. after splitting from the entrance

  Now, in the query, the first question mark refers to inp1, the statement should be:

  ps_getValue.SetString (1, sValue1);

  The second question mark also refers to inp1, so the statement should be:

  ps_getValue.SetString (2, sValue1);

  Given that the third question mark relates to inp2, the statement should be:

  ps_getValue.SetString (3, sValue2);

  and so on...
