REG: CASE WHEN IN WHERE WOULD ADOPT

• using case when statement or decode unfavorable in where clause

  Hi the gems...
  
  I have a problem in the following query...
  I try to use when case statement in where clause of a select query.
  
  
  Select cr.customer_name. ' - ' || CR.customer_number as cust_name,
  CR. Salary salary
  of customer_details cr
  where (case when ' > ' = ' > ' then ' cr.salary > 5000')
  When ' > ' = ' < ' then ' cr.salary < 5000'
  When ' > ' = '=' and then 'cr.salary = 5000'
  Another null
  (end);
  
  
  the expression in the when clause of the statement of the case, when comes from HQ and according to the choice I have to make the where clause.
  That is why, for the execution of the query, I put ' > ' in this place.
  
  If the original query will look like this (for reference):
  
  Select cr.customer_name. ' - ' || CR.customer_number as cust_name,
  CR. Salary salary
  of customer_details cr
  where (case when variable = ' > ' then ' cr.salary > 5000')
  When the variable = ' < ' then ' cr.salary < 5000'
  When the variable = '=' and then 'cr.salary = 5000'
  Another null
  (end);
  
  
  so, in a real case, if the user selects ' > ' then the filter will be ' where cr.salary > 5000.
  If the user selects ' < ' then the filter will be ' where cr.salary < 5000.
  If the user selects '=', then the filter will be 'where cr.salary = 5000 '.
  
  but I get the error "ORA 00920:invalid relational operator.
  
  Help, please... Thanks in advance...

  Hello

  select cr.customer_name || ' - ' ||cr.customer_number as cust_name,

• Problem with case when try to alter the query from siimple

  Hello PL/SQL gurus and Experts.
  
  I'm stuck with a question (can be simple), but not gettings all headsway.
  

  select 365/day_num_yr Anul_Fact from Date where date_dt = trunc(sysdate -1) 

  value returns is as - 1.46
  
  need to write it in the form of case (I have to multiply it to some other outer query), I want to store variable ina and then use the same in an outside -.
  but when use the following syntax, then it always returns 0 and not the same output returned by the query above without the scabbard.

  select (case when date_dt =trunc(sysdate -1) then 365/day_num_yr else 0 END) Anul_Fact 

  Help kindly, I appericate your time and effort in advance.

  user555994 wrote:
  Problem is that I do not get the output as 1.46, even the output is coming like the 0 only if using the query - next

  select /*date_dt, sysdate - 1 prev_dt, trunc(sysdate - 1) trunc_prev_dt,*/
  case when date_dt = trunc(sysdate -1) then  365/day_num_yr
  else 0
  end num_day
  from date_dim;
  

  Completely, which seems to be a question of DATA. Have you checked if the table contains data for DATE_DT = SYSDATE - 1? Can you check if the data stored do not have hours and Minutes stored?

  Although I have provided examples of data, which is the same as the data in my main table and once I used the previous solution you provided and then also gives the result as same as those mentioned by you.

  I think it's something like -

  select date_dt, sysdate - 1 prev_dt, trunc(sysdate - 1) trunc_prev_dt,
  case when date_dt = trunc(sysdate -1) then  366/day_num_yr where day_num_yr=(select day_num_yr from date_dim where date_dt = trunc(sysdate -1))
  else 0
  end num_day
  from date_dim;
  

  Once we get the day_num_yr then he deviding by 366/day_num_yr :(
  but he does not like throwing an error ORA-95 - missing keyword

  Yes, it does not work

  -case when date_dt = trunc (sysdate-1) then 366/day_num_yr where day_num_yr = (select day_num_yr from the date_dim where date_dt = trunc (sysdate-1))

  due to a syntax of alien.
  I don't think that you really need. I already said, with the data in your Table, you will be having only * 1 * record with a Non - zero value. Thus, simply apply a filter to extract the corresponding record SYSDATE - 1 and you should get an output which is Non-zero. If you apply a where predicate, then would not need you a CASE statement. You can directly use something like below:

  select date_dt, sysdate - 1 prev_dt, trunc(sysdate - 1) trunc_prev_dt,
         365 / day_num_yr num_day
    from t4
   where date_dt = trunc(sysdate - 1);

  Hello

  It should be something like this:

  AND CASE
    WHEN 'false'='true' THEN (select id_reserv from demande_livraison where id_env_dep>='-1')
    ELSE id_reserv
       END = id_reserv

• "CASE WHEN 1 = 0 THEN... ON THE OTHER... END '?

  This might be a very basic question I'm still confused about it.
  Can you explain me please "BOX WHEN 1 = 0 THEN... ON THE OTHER... END '?
  Where and why to use this declaration?
  
  
  Help appreciated.

  First Let's break down what it means. Because 1 is never equal to 0, OBI will ignore what comes immediately after and run what comes after the ELSE.

  So, why would we do that? Well, often we want to perform an action that has nothing to do with a particular column in our field. Using this CASE statement, trick us OBI into thinking that we use a column for a calculation or action, but in fact, the column is unchanged.

  For example, suppose that you have been the construction of a line of dashboard. You want to use a column twice in the dashboard command prompt, for example a column ACCOUNT_OPEN_DATE for a range of dates. You cannot use the same column twice in a row of dashboard. (Try it, OBI will ignore your attempt to put the same column twice in your workspace).

  So, what are you doing? You first get a column (in this example, I use a column of type CHAR) as the name of the branch. It doesn't matter which column you are using. The TANK is used the syntax is so logical.

  Move the column to your workspace. Now you click on the amending formula and you type CASE WHEN 1 = 0 THEN organization. "" The branch name ' ELSE 'TEST' END.
  So in this case, the values of the branch name are not affected and the dummy column represents just the word 'TEST '. Now in the 'Show' of the command prompt part, we switch to 'SQL results' and SELECT 'attributes of the account' type. Account_Open_Date OF THE industry and together for a PV called StartDate.

  Because the column is a model, you can call it in fact once again. Use the instruction BOX even make a "dummy" column Then use the same SQL, you used previously, but this time save it in a TICKET called EndDate.

  You now have two date values, you can use your ACCOUNT_OPEN_DATE column to get a date range.

  So, in conclusion, normally you choose a column in the subject box, because you have the values in this column in your report. But when you just need a column to do something unrelated to any column, you use CASE 1 = 0 to make a "dummy" column, and then you can perform your action.

• To convert a new Win 8 PC Win XP PC w/Ffx 28.0, is Ffx 28,0 v. keep? If not, then v. and when and where to install the conversion?

  I will be the conversion of my PC for 9 years with the victory. A new PC with Win XP. 8. my list of program control panel tells me that my old PC running Firefox 28.0 (x 86 en - us). I need to be sure that Firefox 28.0 is your latest version and that I should go to my new PC (it seems to be so many versions out there that it is confusing... in one place you say version 17 is the only one to use). If I do not need to install another version of Firefox, I would need to know that one, and that it must be installed on the old computer first, before changing the PC, or anywhere elsewhere in the in the conversion sequence, that is, on the new PC before (or after?) transfer everything from the old PC. I intend to transfer to new PC software free LapLink offered for us the current XP users through a LapLink/Microsoft agreement.

  Yes, Firefox 28 is the current Windows XP or higher version.

  I'm not exactly sure how works of Laplink, but assuming that he transfer all your data from Windows user profile, then you should bring your Firefox to your new computer data. You can confirm by checking here on both computers and comparing what you see:

  (paste into start > run or WinButton + r): %APPDATA%\Mozilla\Firefox\

  In particular, make sure that Laplink copied the profiles.ini file and folder profile and its subfolders.

  I suggest you copy the data in the first, then installation of Firefox. In this case, when you install Firefox it should automatically find your data and you will be running. If you install Firefox first, then you will need to take some additional precautions to get your old data in.

• The App initialization: when and where?

  In a recent update BB10, I noticed that, if an application is not fully initialize in the 5-6 seconds that newspapers appears:

  forensics_logworthy_state: fixing error 2, no such file or directory, bail

  And the app seems to hang.

  It took a while to figure out what is the code, but how long the code was running - which is the root of my problem. My application has significant amount of initialization to do work, the question is when and where is the best place to do this tedious work?

  I initialially but I had to leave the event loop start and I'd be sure but no, it wasn't the case, always down that has happened.

  Do I have to perform this initialization process in another thread? It is unwise to run this a lot of work in the context of the UI?

  Devs, how you initialize your portions of app NON-INTERFACE?

  I think you yourself have already given your answer, but yes the run in another thread.

  Post a backtrace of the page see the request and the item type properties and the source / default to the value of the P8_MONEY_SAVED_FLAG element.

  Seems to be similar to ORA-06592 with the page only items appear, which also involved a master/detail form. Can you reproduce this on apex.oracle.com?

  Hello

  I have to write the following query using the value of the l_var variable in the case statement

  How do I get there?

  
  Select col3

  of the test

  where col1 = "A".

  and the case

  When l_var = "Y' and col2 = 'B '.

  When l_var = 'n' and col2 = 'C '.

  end;

  In your expression

  case

  When l_var = 'Y' and col2 = 'B '.

  When l_var = ' only then col2 <> 'B '.

  end;

  you try to return a Boolean (True or False) value like 'then' value of the CASE statement.

  Values Boolean are not an Oracle SQL data type, you cannot use the true/false result of col2 = 'B' as an expression. This is why it does not work.

  It's even more simple as:

  Select col3

  of the test

  where col1 = "A".

  and ((l_var = «Y» et col2 = «B») or (l_var = ' no and col2 <> 'B'))

  If you really want a CASE statement then:

  Select col3

  of the test

  where col1 = "A".

  and the CASE WHEN l_var = 'Y', THEN CASE WHEN col2 = 'B', 1 ELSE 0 END

  WHEN l_var = ' no CASE THEN WHEN col2 <> 'B', 1 ELSE 0 END

  END = 1

• Subselect with clause with and nvl() with case when as 2nd argument does not work

  Maybe like this?

  Select)

  (select 1 of the double)

  Select

  NVL (x.a, case when x.a is null, then Itf_Pkg.Itf_Null_Value ("x.a', 'a null value'") or 3 end)

• Error number invalid when using case when

  I have a table called NATIONAL_RARE_ECOSYSTEMS that contains 1 column called TEST_COLUMN (data type: varchar2):
  
  TEST_COLUMN
  rare ecosystem
  rare
  0
  0
  (null)
  (null)
  
  what I want is a query that will add a column called NRE_SCORE that will give each instance of line a score of 0 if it is null.
  If it is 0, then the score should be 0.
  If the line contains any text, partition should be 1
  
  I wrote the request:
  
  SELECT
  (CASE WHEN test_column is null THEN 0)
  WHEN test_column = 0 THEN 0
  WHEN test_column > 0, 1
  END) AS NRE_SCORE
  OF NATIONAL_RARE_ECOSYSTEMS;
  
  I get the error message:
  
  ORA-01722: invalid number
  01722 00000 - "invalid number."
  
  I think it is because on the 2nd and 3rd line, trying to perform arithmetic operations on a column which is varchar2 which I know that I can't do.
  
  How can I write a query that says: If the line contains text, then gives the score of 1?
  
  I'm using oracle 11g.

  Any text other than '0', you mean. I guess that doesn't matter if this text is all the numbers, like '9876 'or something with no numbers, as 'rare'.

  I wrote the request:

  SELECT
  (CASE WHEN test_column is null THEN 0)
  WHEN test_column = 0 THEN 0
  WHEN test_column > 0 THEN 1
  END) AS NRE_SCORE
  OF NATIONAL_RARE_ECOSYSTEMS;

  You are not actually doing arithmetic, but you compare your VARCHAR2 column, so he tries to convert the string to a NUMBER, and that's why you get the error ORA-01722.

  I'm using oracle 11g.

  Here's one way:

  SELECT       CASE
             WHEN  NVL (test_column, '0') = '0'
             THEN  0
             ELSE  1
         END          AS nre_score
  ,       ...          -- you must want other columns, too
  FROM       national_rare_ecosystems
  ;
  

  Since you are not really care on the numerical value, do not use numbers anywhere; stick with VARCHAR2s, for example '0'.

  I hope that answers your question.
  If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) and also publish outcomes from these data.
  Point where the above query was to get erroneous results, and explain, using specific examples, how you get these results of the sample data in these palces.

• any case when and the sql clause

  Hello:
  What follows is my sql clause:
  SELECT T.*, b.name
  OF dbtest1 t
  LEFT OUTER JOIN dbtest b ON t.NO = b.empno
  WHERE t.ChineseName like '% "| : ChineseName | ' %' AND b.name like "%" | : name | » %'
  ORDER BY t.ChineseName
  
  The main problem is that I want to check the b.name if it is null, it can be passed as function NVL, so I try using case when, but it does not work.
  When there are the b.name in where clause, the columns of result will not include data without b.name (or implies the b.name is NULL); And that
  the result data are not entirely accurate.
  is it possible to use the case when it is implemented in the following code snippet:
  
  -case when b.name is not NULL then b.name like "%" | : name | » %'
  Else b.name = NULL (b.name = b.name does not seem to work on the analysis of data zero)
  end
  
  Thank you very much.

  The main problem is the table is the form of the cross, and the like clause will filter the
  data without a name. Basically, it should show the empty columns, however, it won't.
  so, when I test the sql code, I fhound Like "%" | b.Name | ' %' will not get the data when the original dbtest1 table data
  has no id corresponding to the BD test. It seems pointless to go the LEFT OUTER JOIN.

  Thank you

  WHERE t.ChineseName like '%'||:ChineseName||'%'
  AND  (
          b.name like '%'||:name||'%'
         or b.empno is null

• Reg: Case Stmt

  Hi Experts,
  
  I implemented a stmt case to load data from a table to another table (the two tables are same pattern only).
  
  My source as table spec
  
  Select * from EMP
  
  Sal jdate empid EmpName
  Emp1 100 1000 2012
  Emp1 101 5000 2012
  
  even my table target spec also even called as emp1:
  
  
  my code is
  
  
  
  Insert into EMP1
  (
  EMPNAME,
  EMPID,
  SAL,
  JDATE
  
  )
  
  Select
  EMPNAME,
  EMPID,
  SAL,
  JDATE
  
  DE)
  
  
  Select
  EMPNAME,
  EMPID,
  SAL,
  EMPNAME CASE
  WHEN 'EMP' THEN TO_DATE (C4_JDATE, 'YYYY')
  WHEN 'EMP1' THEN TO_DATE(C4_JDATE,'dd-mon-yyyy')
  WHEN 'EMP2' THEN TO_DATE(C4_JDATE,'mm/dd/yyyy')
  end JDATE
  from EMP
  where (1 = 1)
  
  
  
  This query above works fine, but when the time to display the basic data in emp1 as of data
  
  JDate as: July 01, 2012
  
  data remaining is fine.
  
  
  Have that I need to change the date format of database to jdate disaplay as 2012 (yyyy)...
  
  Please suggest me where I need to change...
  
  
  Thank you

  Oracle date formats needs to be in a year, month, day, and hour of the elements. If update us or insert a value into a date column that does not have some of these Oracle components using the default values.

  Thus, if provide us everything a year that oracle will generate a date which is midnight the first day of the current month. It's what you do, and is why you currently values JDATE July 1, 2012. If you run your code on Wednesday you will find the JDATEs will be August 1, 2012.
