• 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);

• Interview with case/when & sum() over (partition) producing unexpected lines

  Since some time ago, I asked a question in this forum on an unusual problem of join and subtract ( subtract the total periods of highest level duration ). I had what seemed like a work request. So far, I could not really use it. Now that I'm looking closer results, I think that there is something wrong with it, but I can't understand why it's happening.
  
  Using the definition of the table of the original question, the following simple query shows a special extract of the data I'm looking at.
  
  Select duration, event_type, start_time, code_range, request_id from MYTABLE where REQUEST_ID = 'abc '.
  
  This translates into the following lines (separate columns by ' / '):
  
  START_TIME/REQUEST_ID/EVENT_TYPE/CODE_RANGE/DURATION
  2010-11-12 01:42:04.0/abc/Junk/publicEntryPoint/2,003
  2010-11-12 01:42:04.0/abc/Junk/webServiceCall/947
  2010-11-12 01:42:04.0/abc/Junk/webServiceCall/969
  
  Another similar request with REQUEST_ID = 'def' means:
  
  START_TIME/REQUEST_ID/EVENT_TYPE/CODE_RANGE/DURATION
  2010-11-12 00:22:13.0/def/junk/webServiceCall/788
  2010-11-12 00:22:13.0/def/junk/webServiceCall/1,128
  2010-11-12 00:22:13.0/def/junk/publicEntryPoint/2,003
  
  What follows is an excerpt simplified query I have a problem with:
  
  Select value start_time request_id event_type, code_range, duration, case code_range
  When "publicEntryPoint" then length * 2 - sum (duration) over (partition by request_id)
  of another-1
  end inner_duration from MYTABLE where EVENT_TYPE = 'spam' and trunc (START_TIME) = to_date('2010-11-12','yyyy-mm-dd')
  and rownum < 1000;
  
  Notice the couple of unconventional functions used here, the ' case/when' and 'sum() over (partition).
  
  This property returns a bunch of lines (count: 999), but here are the two with the particular REQUEST_ID values:
  
  START_TIME/REQUEST_ID/EVENT_TYPE/CODE_RANGE/DURATION/INNER_DURATION
  2010-11-12 01:42:04.0/abc/junk/publicEntryPoint/2,003/2,003
  2010-11-12 00:22:13.0/def/junk/publicEntryPoint/2,003/87
  
  The second line is correct. The first line has an unexpected value of INNER_DURATION of 2003. It should be 87 as the second row. I don't understand why this is happening.

  I think that 'and rownum '.<1000" must="" be="" the="" problem.="" it="" must="" be="" excluding="" some="" of="" the="" rows="" needed="" for="" the="" sum.="" the="" analytic="" function="" will="" be="" applied="" after="" this="" condition--see="" the="" sql="">

  Analytical functions are the last set of operations performed in a query, except for the
  final ORDER BY clause. Every joint and every WHERE, GROUP BY and HAVING clauses are
  completed before the analytical functions are processed

  Have you tried the query without this condition?

• Need help with CASE When statement in a Where Clause

  So I have a SQL (simplified for this forum)
  
  Select t1.*

  and when t1.field2 is null then trunc (sysdate) < = trunc (t1.date1 + 17)

  I end up getting an error ORA-00905: lack of keyword
  
  I'm sure that I just got something here involved.

  You can not make the comparison within the statement underlying case like this. Assuming you have appropriate data types, something like this should work

  Select t1.*
  from table1 t1, table2 t2
  where t1.field1 = t2.field1
    and ((t1.field2 is null and
          trunc(sysdate) <= trunc(t1.date1 + 17)) or
         trunc(sydate) > = trunc(t2.date2 + t2.date3))

  No, your SQL is not that.

  The select statement that you put online here, aside from being not not in brackets, is the selection of two values, but you can provide two values for the result column.

  Without knowing who the SQL statement, we can highlight only the obvious questions.

• "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.

• Box When sql with clob in the criteria

  I have the following select statement with a 'case when' which has a clob field in the criteria.
  I get an ORA-00932 inconsistent types of data: expected - got CLOB error.
  

  CASE WHEN FROM_FIELD = 'REOPEN'
  THEN
  (SELECT MIN(MODIFIED_DATE)
  FROM RECORDS
  WHERE MODIFIED_VALUE = 'CLOSE')
  ELSE CLOSED_DATE
  END
  [/CODE]
  
  There is a lot more to the SQL above, but it is basically what I am looking for.
  Looking for help with how to run this with the CLOB field (Modified_Value) in the criteria.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    

  A strange with clob column is

  SELECT MIN(MODIFIED_DATE)

  will give you error

  But

  SELECT MIN(MODIFIED_DATE)
  FROM RECORDS
  WHERE MODIFIED_VALUE like '%CLOSE%';
  

  This will give record... :)

  Use a different approach to the CASE and the IN operator. Like this:

• 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

  I need to validate the condition in the event, that is when the new date after check if it is higher, then start date. If it is higher, then it should be updated with the new start date.
  If not, it must be updated, it will be the old value.
  
  I use it under request
  
  Update workingdate set name = 'sss', startdate =)
  case
  When
  (TO_DATE('2011-12-10','yyyy-MM-dd') > (select TO_DATE(startdate,'yyyy-MM-dd') from the workingdate, when sno = 1))
  then TO_DATE('2011-12-10','yyyy-MM-dd')
  on the other
  Select TO_DATE(start_date,'yyyy-MM-dd') in the workingdate, when sno = 1
  end
  )
  where sno = 1;
  
  
  but when I run the above query, it shows me
  
  
  Error report:
  SQL error: ORA-00936: lack of expression
  00936 00000 - "missing expression.
  * Cause:
  * Action:
  
  How could I solve this problem...

  Check this

  UPDATE workingdate
  SET NAME='sss',
       startdate=(CASE WHEN (TO_DATE('2011-12-10','yyyy-MM-dd') > startdate THEN TO_DATE('2011-12-10','yyyy-MM-dd') ELSE start_date END)
  WHERE sno=1;
