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
FROM tab1
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.

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

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

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;

DB Function errors out when trying to use in both Answers and RPD file.

Hi All,
Its a strange behaviour that one function which is in Database works fine the other does not. I have created 2 DB functions and accessing them from OBIEE in both Answers and RPD. One function which returns a Date is working fine, the one which is returning a number is throwing a error.

Both functions are in same schema, have the similar grants.
Please help me resolving this error. Any pointers in resolving this is much appreciated.
Thanks,

I noticed that you have not specified the type of return value that the function returns. It is good practice to do so..
EVALUATE('DB_Function(%1)' as returntype, {Comma separated Expression}).
Try EVALUATE('APPS.XXX_BUSINESS_DAYS(%1,%2,%3)' as number,"Soft cost Fact"."Soft Cost Date","Soft cost Fact"."Soft Cost Date",1) to see if that resolves the error.
Also check this out if you haven't already.

Evaluate function doesn't work with Static values

Hi All,
I have been trying to call a evaluate function and have been successfully in calling it..but i face problem when i pass any static values to it...
For eg
when i try calling the function using one of the columns...it works fine
Evaluate('dbo.Hello(%1)',"Dim table_name"."Department" )
the function normally changes it to upper case.so i get all the value in the column in department in upper case.
but when i call any static value like
Evaluate('dbo.Hello(%1)','hello') it throws the following error..
[nQSError: 43113] Message returned from OBIS. [nQSError: 43119] Query Failed: [nQSError: 42015] Cannot function ship the following expression: Evaluate( dbo.Hello(%1),'hello') . (HY000)
Can any one please help me in this

SQL Expression in decode function or case statement?

Can I put SQL expressions in decode function or case statement?
For example,
select le.profile, decode( select count(1) from profile_data where NAME= 'XXXX_AFTER' and object_id = le.profile, 0, 'N', 'Y')
from element le;
or
select le.profile, case WHEN ( select count(1) from profile_data where NAME= 'XXXX_AFTER' and object_id = le.profile) = 0 THEN 'N'
ELSE 'Y'
from element le;
None of the above work.
Can anyone tell me how to make it work?
Is there any workaround?
Thanks,
J

You simply needed and END to your CASE statement;
SQL> with profile_data as (
   select 'XXXX_AFTER' name, 1 object_id from dual),
     element as (
   select 1 profile from dual union all
   select 2 from dual)
select le.profile,
   case WHEN ( select count(1) from profile_data where NAME= 'XXXX_AFTER' and object_id = le.profile) = 0
   THEN 'N'
   ELSE 'Y'
   END new_col
from element le
   PROFILE N
         1 Y
         2 N

Can we use Evaluate function in Prompt

Hi all
Can we use Evaluate Function in Dashboard Prompt?
I need some exposure on how to use it.
I am working on a HRMS-OLTP Source where I need to work with Oracle Functions from OBIEE.
IF somebody can tell me that, It will be a favour for me....
ThanQ

Hi All,
Here's an example of how to use evaluate. This use calls the Oracle TO_DATE function: EVALUATE('TO_DATE(%1,%2)' as DATE, '03/03/2009', 'MM/DD/YYYY')
Here's how it works: EVALUATE( '<FUNC>' AS <DATATYPE>, VALUE1,VALUE2,etc)
FUNC) Is the syntax for the function you are calling. Any parameters have to be replaced by %<number>, where number refers to the order in which you specify your parameters.
DATATYPE) The datatype that the function will evaluate to. In this case, DATE.
VALUE1) The latter part of the formula is a comma separated list of all the parameters used in the function. In this case, it's the date I want to cast
VALUE2) This is the second parameter. You need as many as you referenced in your function. In this case, it's the date format.
Good luck and if you found this post useful, please award points!
Best regards,
-Joe

Using CASE WHEN in PL/SQL package

Evaluate function in OBIEE

Hi All,
I tried using Evaluate and Evaluate_Aggr in the column formula of a report.
Evaluate_Aggr() is erroring saying the dimension Work Order is incorrectlly defines logical Table Source Mapping for a dimension of Work Order. If I revoke the implicit fact coniguration on this Subject Area which I have, the report executes as expected. But this implicit configuration is required in my scenario for other reports to work.
Using Evaluate() works perfectly.
Can anyone help me in fixing this?
Shld I add any other configuration in the RPD to resolve this issue?
Thanks

Best practices on using EVALUATE functions

hi, experts,
I wanna know what is the best practices on using EVALUATE functions on obiee (calling oracle user defined functions)
I found that if I use evaluate functions in Answers,
obiee will construct a sql behind and then execute.
sometimes, obiee contructs some unexpected sqls, and returns errors.
so, is it better to use EVALUATE functions in logical columns ?
thanks

EVALUATE('DB_Function(%1)' as returntype, {Comma separated Expression})
even when used in Logical columns, its gonna fire the same sql.

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
