CASE WHEN functionality in BI Publisher

I have previously used Discoverer to do our reporting and am investigating the differences between the two products. I understand that its chalk and cheese but one thing I am having trouble identifying is the CASE WHEN functionality that we use Discoverer in BI Publisher.
An example of the usage for our CASE WHEN would be creating a derived column in a report to convert existing data into a more standardised format.
I imagine this is quite a simple answer and I have just missed it but could anyone out there help me with where I can input the functionality in BI publisher.
I am not the most technically gifted so any answers with simple words help :-)

You can use CASE WHEN in a sql query in a data model. You can also use it in the RTF template via "if then else", choose statements etc
Take a look at section 4.10 in the BI publisher Report Designer's guide for use cases/examples: http://docs.oracle.com/cd/E23943_01/bi.1111/e22254.pdf

How to use case when function to calculate time ?

Dear All,
May i know how to use case when function to calculate the time ?
for the example , if the First_EP_scan_time is 12.30, then must minus 30 min.
CASE WHEN FIRSTSCAN.EP_SHIFT <> 'R1' AND FIRSTSCAN.EP_SHIFT <> 'R2'
THEN ROUND(CAST((DATEDIFF(MINUTE,CAST(STUFF(STUFF((CASE WHEN SHIFTCAL.EP_SHIFT = 'N1'
THEN CONVERT(VARCHAR(8),DATEADD(DAY,+1,LEFT(FIRSTSCAN.EP_SCAN_DATE ,8)),112) + ' ' + REPLACE(CONVERT(VARCHAR(8),DATEADD(HOUR,+0,SHIFTDESC.EP_SHIFT_TIMETO + ':00'),108),':','')
ELSE LEFT(FIRSTSCAN.EP_SCAN_DATE ,8) + ' ' + REPLACE(CONVERT(VARCHAR(8),DATEADD(HOUR,+0,SHIFTDESC.EP_SHIFT_TIMETO + ':00'),108),':','') END),12,0,':'),15,0,':') AS DATETIME),CAST(STUFF(STUFF(LASTSCAN.EP_SCAN_DATE,12,0,':'),15,0,':') AS DATETIME)) / 60.0 - 0.25) AS FLOAT),2)
ELSE ROUND(CAST((DATEDIFF(MINUTE,CAST(STUFF(STUFF(FIRSTSCAN.EP_SCAN_DATE,12,0,':'),15,0,':') AS DATETIME),CAST(STUFF(STUFF(LASTSCAN.EP_SCAN_DATE,12,0,':'),15,0,':') AS DATETIME)) / 60.0) AS FLOAT),2) END AS OTWORK_HOUR

Do not use computations in a declarative language. This is SQL and not COBOL.
Use a table of time slots set to one more decimal second of precision than your data. You can now use temporal math to add it to a DATE to TIME(1) get a full DATETIME2(0). Here is the basic skeleton.
CREATE TABLE Timeslots
(slot_start_time TIME(1) NOT NULL PRIMARY KEY,
slot_end_time TIME(1) NOT NULL,
CHECK (start_time < end_time));
INSERT INTO Timeslots --15 min intervals
VALUES ('00:00:00.0', '00:14:59.9'),
('00:15:00.0', '00:29:59.9'),
('00:30:00.0', '00:44:59.9'),
('00:45:00.0', '01:00:59.9'),
('23:45:00.0', '23:59:59.9');
Here is the basic query for rounding down to a time slot.
SELECT CAST (@in_timestamp AS DATE), T.start_time
FROM Timeslots AS T
WHERE CAST (@in_timestamp AS TIME)
BETWEEN T.slot_start_time
AND T.slot_end_time;

Data missing in Crosstab report with calculated field via case when

I use the Oracle 10g discoverer. When I create a crosstab report with a calculate field via function case when and put it as datapoint, some of the data is not showing. I tried to not use the case when function for the calculate field, then all the data show.
I really do not the reason. Could anybody help me out with many thanks?

Let me explain more.
I have the original data below.
Work order, Team, Hours_worked, date
800001, S1, 5, 2012/01/01
800001, S1, 15, 2012/01/10
800001, S2, 4, 2012/01/04
800002, S1, 3, 2012/01/15
There are multipul records for the same work order, team on the same day or different.
Finally I want to set the start date and end date as the parameter to create a crosstab report format like
start date>=2012/01/01 and close date<=2012/01/05
Team
Total hours total hours within the range
Work order S1 S2 ... S1 S2 ...
800001 20 4 5 4
800002 3 0 0 0
in order to do it, I create two parameters independently start date and close date. Then I create a calculate field hours_worked_withinrange via
Case when date>=:start date and date<=:end date then Hours_worked else 0 end
This calculated field is correct in the tabular format report in discoverer desktop. But when I duplicate the list as crosstab. Some data is missing in crosstab data point.
I checked once I change the calculate field defination not use case when. (For example, C1=hours_worked*2). Then everything runs correct.

Using case when to an aggregate function

Hi,
I have a sql statement like below,
Select CASE WHEN (Sum(Amount) Over (Partition By Name),1,1) = '-' THEN 0 ELSE Sum(Amount) Over (Partition By Name) END AS Amount_Person
From tbPerson
But when I run the sql statement above I got error ORA-00920: invalid relational operator. What I'm trying to do is when the total amount for each person is negative then it will return 0 else it will return the positive value. I dont want to use the GROUP BY function. Is there any other way than using the Sum Over function? Thanks

Like this?
SELECT CASE WHEN Sum(Amount) Over (Partition By Name) < 0 THEN 0
            ELSE Sum(Amount) Over (Partition By Name)
       END AS Amount_Person
FROM tbPerson
;or using GREATEST function :
SELECT GREATEST(
         Sum(Amount) Over (Partition By Name)
       , 0
       ) as Amount_Person
FROM tbPerson

MIN function iside CASE WHEN

Hi gurus,
I am new to PL SQL and wanted to know that cant we put MIN inside the CASE WHEN.
I have following mentioned query:
It is not allowing me to execute it, can anyone help me out?
SELECT A,
B,
D,
E,
F,
SUM
(CASE
WHEN <Expression> THEN (CASE
WHEN ( <Expression>
THEN 0
ELSE min(<Expression>) or min(<Expression>)
END
ELSE 0
END
) AS sales

WHERE ( column1 = 'x' )
GROUP BY A,
B,
D,
E,
F,
Edited by: user11001347 on Oct 29, 2009 2:34 AM

Group functions within a case are perfectly acceptable e.g.
select sum(case when dummy = 'X' then '1' else min(dummy) end) from dual group by dummy
SUM(CASEWHENDUMMY='X'THEN'1'ELSEMIN(DUMMY)END)
1There are other problems with your code...
This looks wrong to me:
min(<Expression>) or min(<Expression>)and you have a trailing comma after F in the group by clause.
When you're having problems with a piece of SQL, It's useful to us if you post the error you are getting back, and your table structure and sample test data too if possible.

Using CASE WHEN in PL/SQL package

Discoverer: "CASE WHEN...." in calculations won't show anything in GUI !?!?

Hi all!
I have a report in Discoverer Plus (Version 10.1.2.48.18) which contains 2 columns: One with actual spendings and one with budget figures. I want to make a third column which holds actual spendings in percentage of the budget. To do this, I need to make a calculation similar to:
CASE WHEN SUM(budget) <> 0 THEN SUM(spendings)/SUM(budget) ELSE NULL END
However, when I apply this calculation to the third column, my report don't return any numbers at all in any column.
What am I doing wrong? -- Is this a bug, and how should I solve my problem?
~Morten

I can get something out if I do this (applying an aggregate function to it all):
SUM(CASE WHEN budget <> 0 THEN spendings/budget ELSE NULL END)
However, this is wrong (Summarizing these percentages doesn't give any meaning).
SQL lookes something like this:
SELECT /*+ NOREWRITE */ o100448.ACCOUNT as E100451,(decode((ADD_MONTHS(o100862.DATE1,-4)),null,to_date(null, 'MMDDYYYY'),to_date(to_char(trunc((ADD_MONTHS(o100862.DATE1,-4)),'YYYY'),'YYYY') || '01','YYYYMM'))) as E101004,MAX(o100448.ACCOUNTNUM) as as100473_100451_NEW,CASE WHEN ( SUM(o100862.BUDGET) ) <> 0 THEN ( SUM(o100862.AMOUNT) )/( SUM(o100862.BUDGET) ) ELSE NULL END as C_1,( SUM(o100862.BUDGET) )*o100448.SIGN as C_3,( SUM(o100862.AMOUNT) )*o100448.SIGN as C_2,GROUPING_ID(o100448.ACCOUNT,o100448.SIGN,(decode((ADD_MONTHS(o100862.DATE1,-4)),null,to_date(null, 'MMDDYYYY'),to_date(to_char(trunc((ADD_MONTHS(o100862.DATE1,-4)),'YYYY'),'YYYY') || '01','YYYYMM')))) as GID
FROM TANGO.TANGO_ACCOUNTS o100448,
TANGO.TANGO_SUMS o100862
WHERE ( (o100862.ORG = o100448.ORG AND o100862.ACCOUNTNUM = o100448.SUBACCOUNTNUM))
AND (o100448.ACCOUNTNUM BETWEEN 30000 AND 79999)
AND (o100862.DIM = '50')
AND (o100448.ORG = 'bru')
GROUP BY GROUPING SETS(( o100448.ACCOUNT,o100448.SIGN,(decode((ADD_MONTHS(o100862.DATE1,-4)),null,to_date(null, 'MMDDYYYY'),to_date(to_char(trunc((ADD_MONTHS(o100862.DATE1,-4)),'YYYY'),'YYYY') || '01','YYYYMM'))) ),( o100448.ACCOUNT,(decode((ADD_MONTHS(o100862.DATE1,-4)),null,to_date(null, 'MMDDYYYY'),to_date(to_char(trunc((ADD_MONTHS(o100862.DATE1,-4)),'YYYY'),'YYYY') || '01','YYYYMM'))) ))
HAVING (GROUP_ID()=0)
ORDER BY GID DESC;
I tried to fire this SQL up in TOAD (or whatever SQL-tool you might have), and columns C_2 and C_3 are empty. Seems like I'm doing something awfully wrong here.....
Any ideas? (There must be some SQL sharks out there ;-p)

Font issues when in preview or publishing project (Captivate 4)

I am continuing to experience problems with fonts in my projects.
As a standard, I am only using Verdana 11 pt and 10 pt in my slides. This standard/consistancy is quite evident when I am viewing the slides in edit view. However, when I preview or publish the project, the text from slide to slide is not consistant.
It appears as through some slides display Vendana slightly squished... it is clearly Vendana just reduced in height. I have tried various options, such as setting the quality mode and so far,nothing has helped.
Please see the attachment, which should better illustrate what I am describing. Each of the five 100% cropped screen captures are from separate slides and I have combined them into one jpg.
Any ideas?

Hi Shawn
Sorry I didn't see this before you went to the trouble of deleting the dat file. I would have speculated this would have had no difference whatsoever.
It's common to see folks report issues with Transparent captions. Normally the report is that the captions are "blurry" or "fuzzy". Usually it's because of anti-aliasing. There are ways past it.
Fellow Adobe Community Expert Paul Dewhurst initially discovered that if you simply highlight one blank character using the color #C0C0C0 the caption would render without anti-aliasing.
Later we discovered that if the caption had a bullet point anywhere in the text, it would render without anti-aliasing. That seems simpler to me than using the highlight. What you do is just add a few blank lines, apply the bullet to the last line, then size the caption so you don't see the bullet. (assuming, of course, that you had no bullets elsewhere. In that case it would be unnecessary to do this)
The Captivate developers added in an option where you may enable/disable anti-aliasing globally. This is done via Edit > Preferences > Project > SWF Size and Quality.
Hopefully something there was helpful... Rick

Another case when statement

Hi, another case statement question. My set up is calling from dasnboard prompt to publisher with an rtf template. My question is whether my logic/syntax is corrected. Thank you.
and "office"."branch" = ( CASE WHEN :BRANCH = '' THEN "office"."branch" ELSE :BRANCH END)
case when :BRANCH is null THEN 'or' ELSE 'and' END -----> (here I want to be able either or / and in case when edit box with BRANCH parameter is null use OR operator and when BRANCH parameter is field use AND operator.
and "office"."employee" like upper( CASE WHEN :EMPLOYEE = '' THEN "office"."employee" ELSE :EMPLOYEE END)

try this in TOAD (replace each apostrophe of your sql by two apostrophes and add the starting and ending apostrophe to obtain a string)
execute immediate 'INSERT INTO DATAMART.PERSONSITE (PERSON_DBID,SITE) SELECT PDBIDSKILL.DBID, MIN(PDBIDSKILL.SKILL) FROM
(SELECT DISTINCT DATAMART.V_CFG_PERSON.DBID, CASE WHEN DATAMART.V_CFG_SKILL.NAME=''Complex_Rslve'' OR DATAMART.V_CFG_SKILL.NAME=''Broadband_Business_Resolve'' THEN ''BBHD'' WHEN DATAMART.V_CFG_SKILL.NAME=''General'' OR DATAMART.V_CFG_SKILL.NAME=''General_Mobile'' OR DATAMART.V_CFG_SKILL.NAME=''General_Billing'' THEN ''MASS'' WHEN DATAMART.V_CFG_SKILL.NAME=''Faults_General'' OR DATAMART.V_CFG_SKILL.NAME=''Faults_Business'' THEN ''Faults'' ELSE ''_Other'' END AS SKILL

INNER JOIN DATAMART.V_CFG_PERSON ON DATAMART.V_CFG_PERSON.DBID = DATAMART.V_CFG_SKILL_LEVEL.PERSON_DBID) PDBIDSKILL GROUP BY PDBIDSKILL.DBID';it should give the same result as your original sql statement
before using the string in VBA you must replace '' with the characters used to denote an apostrophe within apostrophes.
I don't know nothing about VBA but I'm sure you'll know how to deal with it (an apostrophe within apostrophes).

If you have more questions, please let us know.
Edited by: New Yorker on Aug 31, 2010 10:08 AM

New Yorker,
According to the given SQL block, the case function can not be used. You can use the case function with multiple table joins but you can only use the CASE WHEN ELSE END block for one column.
If i got your question correct, that is my answer to your question.

Use of when function with linking sheets

Hello,
So I went through the Manual and the Forum.
There is no German Forum so WENN means IF and WAHR means TRUE;
If I enter this function:
=WENN(G6=WAHR;"=Blatt 3 :: Tabelle 1 :: B6";"nix")
it respondes in case of RIGHT the string "Blatt 3 :: Tabelle 1 :: B6"
but should take the value (Date in this case)! If i use just
=Blatt 3 :: Tabelle 1 :: B6
whitout when function,
it responses fine the Date of the refered sheet respective matrix respective cell, in this case 05.01.2006 (whatever:)
Has anyone a clue what´s going on ??
Thanks in advanced

Ananas,
It appears that your formula contains three extra characters: "= and "
Try: =WENN(G6=WAHR;Blatt 3 :: Tabelle 1 :: B6;"nix")
By the way, thanks for the translations.

SELECT CASE WHEN not working?

Hello, can't figure out why the following statement continues to return NULL values and seems to not recognize my case when portion?...
INSERT tbl_Main
select OrderID
,(select
  case
   when (b.OrderValue is null or b.OrderValue = '') then 'Y'
   else b.OrderValue
  end
from tbl_OrderDetails b where b.OrderID = a.OrderID and b.DetailID = '7')
AS OrderStatus
from tbl_Order a
Thanks in advanced.

Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules. Temporal data should
use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
This is minimal polite behavior on SQL forums.
1. The use of the “tbl-” prefix is a design flaw called “tibbling” and people will laugh at you for it.
2. Do not nest selects inside a select list; the performance stinks.
3. Why do you think “A”, "D” etc are good aliases that will make maintaining this code easier? Noobs do this is match the names of tape drives on old hardware!
4. Why do you think that treating a NULL and an empty string as the same is a good idea? Use a CHECK (order_value <> '').
My guess is you could write this instead:
INSERT INTO Orders
SELECT order_id, COALESCE (D.order_value, 'Y') AS order_status
FROM Order_Details AS D
WHERE D.order_id = Orders.order_id
AND D.detail_id = '7')
AS order_status;
But this still smells bad. A status is a state of being so it has a temporal component. Order details do not usually have an id; the item identifier (EAN, UPC, SKU, or whatever) is used.
