Using cfif v/s CASE WHEN

Hi everyone,
I'm currently working on optimizing a report that takes about
2 minutes to load. The main reason is that it has sooo much data. I
noticed 2 things that i might be able to improve on...first there
are a ton of <cfif> statements and second there are so many
Query of Queries for each record. Basically I need help with these
2 things:
1) There are quite a few boolean fields. Currently the logic
is on the .cfm page meaning for a certain boolean field, we use
<cfif qryGetPipelines.pipebdw_is_me_tech_assistance eq
1>
Y
<cfelse>
N
</cfif>
My question is that would it better and more efficient if i
just use a CASE WHEN pipebdw_is_me_tech_assistance = 1
THEN....statement in the query and that way i don't have to do the
<cfif> on the .cfm page?
2) My second question is: let's say the report pulls up 400
records, i then loop through those records and display the
different fields and i also perform about 10 Query of Queries in
each loop to get fields that have more then 1 record. So bascially,
for each of the 400 records, i have 10 additional Query of Queries
and though it's only about 15 - 20 ms per query...when you add
multiply 10 * 400 it takes up quite a lot of time. Is there any
other way around this??
Thank you so much for all your help.
Anju

@Ian - Thanks for your help Ian and the answer to your
question is yes i do plan to put the CASE statement in the Sql
query, currently the logic is being done by using <cfif> on
the .cfm page.
@Dan - Thanks for your help as well. Can you please give me a
little more info as to what would be a more effiicient way then
looping through a query in order for me to display about 30 columns
(fields) of data for anywhere from 400 - 1000 records?
Thanks again for all your help

Using more than one case when statement

Hi there,
I have a question on using case when statements.
Currently I have a table where it shows me mulitple dates.
Order Saledate TransferDate StartDate Enddate GetDate
I have created a where statement to show me records against the transferdate dependant if it appears within the date range of the year, or if it appears within the startdate and today's date.
(lpatran.trandate between targets.startdate
and (case when targets.enddate < getdate() then targets.enddate else getdate() end))
However on some of the records the transfer date is null, and so they want to use the saledate as the date to use.
So I created
(case when Lpatran.trandate is not null then (Lpatran.trandate between targets.startdate
and (case when targets.enddate < getdate() then targets.enddate else getdate()))
else (lpatran.saledate between targets.startdate
and (case when targets.enddate < getdate() then targets.enddate else getdate())) end )
However it gives me an incorrect syntax near the word ‘between ‘
Is there a simple fix for this or does sql not allow me to do this?

I have created a new column called transferdate and done a case when statement
CASE
WHEN lpatran.trandate
IS
NULL
THEN lpatran.saledate
ELSE lpatran.trandate
END
AS Transferdate,
Then created a temptable and did a select * from temptable. Created a where statement from transferdate, which does work and gives me the correct data.
TransferDate between startdate
and(case
when enddate
<
getdate()
then enddate
else
getdate()
end))
However I wanted to know if there was a way of obtaining the same data without having to use the temptable ?

Using 'DECODE' instead of 'CASE' in select

Using case when statement in the select query to create physical table

Hello,
I have a requirement where in I have to execute a case when statement with a session variable while creating a physical table using a select query. let me explain with an example.
I have a physical table based on a select table with one column.
SELECT 'VALUEOF(NQ_SESSION.NAME_PARAMETER)' AS NAME_PARAMETER FROM DUAL. Let me call this table as the NAME_PARAMETER table.
I also have a customer table.
In my dashboard that has two pages, Page 1 contains a table with the customer table with column navigation to my second dashboard page.
In my second dashboard page I created a dashboard report based on NAME_PARAMETER table and a prompt based on customer table that sets the NAME_ PARAMETER request variable.
EXECUTION
When i click on a particular customer, the prompt sets the variable NAME_PARAMETER and the NAME_PARAMETER table shows the appropriate customer.
everything works as expected. YE!!
Now i created another table called NAME_PARAMETER1 with a little modification to the earlier table. the query is as follows.
SELECT CASE WHEN 'VALUEOF(NQ_SESSION.NAME_PARAMETER)'='Customer 1' THEN 'TEST_MART1' ELSE TEST_MART2' END AS NAME_PARAMETER
FROM DUAL
Now I pull in this table into the second dashboard page along with the NAME_PARAMETER table report.
surprisingly, NAME_PARAMETER table report executes as is, but the other report based on the NAME_PARAMETER1 table fails with the following error.
Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 16001] ODBC error state: S1000 code: 1756 message: [Oracle][ODBC][Ora]ORA-01756: quoted string not properly terminated. [nQSError: 16014] SQL statement preparation failed. (HY000)
SQL Issued: SET VARIABLE NAME_PARAMETER='Novartis';SELECT NAME_PARAMETER.NAME_PARAMETER saw_0 FROM POC_ONE_DOT_TWO ORDER BY saw_0
If anyone has any explanation to this error and how we can achieve the same, please help.
Thanks.

Hello,
Updates :) sorry.. the error was a stupid one.. I resolved and I got stuck at my next step.
I am creating a physical table using a select query. But I am trying to obtain the name of the table dynamically.
Here is what I am trying to do. the select query of the physical table is as follows.
SELECT CUSTOMER_ID AS CUSTOMER_ID, CUSTOMER_NAME AS CUSTOMER_NAME FROM 'VALUEOF(NQ_SESSION.SCHEMA_NAME)'.CUSTOMER.
The idea behind this is to obtain the data from the same table from different schemas dynamically based on what a session variable. Please let me know if there is a way to achieve this, if not please let me know if this can be achieved in any other method in OBIEE.
Thanks.

Using CASE WHEN for Essbase column in OBIEE 11g

Hi all,
I have a business model in OBIEE 11g, taking the source from Essbase 11. The measures of the Essbase cube in the physical layer is flattened, and the aggregations for the measures are set to SUM.
The Product dimension has 5 generations. In Product logical table, I created a logical column called "Product Grouping" using a simple CASE WHEN formula:
CASE
WHEN "TEST"."Product"."Gen5,Product" IN ('100-10', '100-20', '200-10', '300-10') THEN 'Group 1'
WHEN "TEST"."Product"."Gen5,Product" IN ('100-30', '200-20') THEN 'Group 2'
ELSE 'Group 3'
END
Problems:
1. If I don't place this "Product Grouping" in the logical level/hierarchy, I got error in the report when I simply show Product Grouping and a measure.
2. If I place this "Product Grouping" in the logical level/hierarchy (on the 5th level), no more error in the report when I simply show "Product Grouping" and a measure. The measure value also shows the correct SUM (group by). However, when I add "Gen1,Product" the "Product Grouping" and the measure value suddenly becomes not grouped by.
Has anyone ever tried and encountered something like this? Any thoughts?
Thank you very much!

Hi Deepak, thansk for the suggestion.
However, I can't use calculated item for this report because:
1. incorrect result will be shown when my measures involve a formula to derive a percentage value.
2. calculated item is not available if we do "combine requests" (or union) in 11g.
Any thoughts anyone on how to solve this? Is this just me, or it's a bug?
Thank you very much.

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

Using :case when in where clause

Hello,
I need some help with using of case statement in a where clause
Table that contains info about employees taking some coursework:
Class (values could be SAP, ORACLE, JAVA)
Code (if Class is SAP then CODE is not null; if class is any other CODE is NULL)
Start Date (date they began class not null)
End Date (date then ended the class - could be null)
Employee Level(numbers from one through five)
I need a single LOV in forms that should show Employee_Level for input class,code,date.
How to do this?
I started off with this but get 'missing statement error'
select distinct employee_level from e_course
   where (
   case when &class='SAP' then code ='1' and start_date > to_date('20000101','YYYYMMDD') and
                                           end_date < to_date('20000101','YYYYMMDD')
           else
               null
   end) order by employee_level;Thanks

Hi,
user469956 wrote:
But all these examples have only one condition for each case.Depending on how you count, all WHERE clauses have only one condition.
I see an example in that thread that has 6 atomic conditions, linked by AND and OR.
I need to check date & code. This is what is causing the error.Why do you want to use a CASE statement?
Why can't you put all your conditions directly iinto a WHERE clause, soemthing like this:
WHERE   (   &class='SAP'
        AND code ='1'
OR      (   start_date > to_date('20000101','YYYYMMDD')
        AND end_date    < to_date('20000101','YYYYMMDD')
        )I said "something like this" because I don't know what you really want to do.

Using CASE WHEN THEN in dynamic Region Source area

Hi all,
I've been knocking my head around on this one for a while. Hope someone can show me some guidance. So far, the SQL Query in the Region Source works ok except after the THEN ''||'LINK'||'' . All text between the single quotes displays, and not just the hyperlink LINK. (My goal is to this simple test working, then go back an substitute in APP_ID, Page#, SESSION variables.) But I'm stuck with this problem. Searched the forum but this is as far as I got. Below is the code I'm using in the Region Source area. Perhaps a region attribute setting is needed but I'm unsure. Thanks for any assistance. -Mike

All text between the single quotes displays, and not just the hyperlink LINK.Not clear from this what the problem is. It appears to me that LINK is all of the "text between the single quotes". What do you mean by "all text"? (An example on apex.oracle.com is a good way to resolve such ambiguities...)
The usual cause of unexpected results when the separation of concerns is breached and HTML is directly generated in report queries is having the Display Text As report column attribute wrongly set. Ensure it is Standard Report Column rather than the default Display as Text (escape special characters).

Using case when statement or decode stament in where clause

hi gems..
i have a problem in the following query..
i am trying to use case when statement in the where clause of a select query.
select cr.customer_name || ' - ' ||cr.customer_number as cust_name,
cr.salary as salary
from customer_details cr
where (case when '>' = '>' then 'cr.salary > 5000'
when '>' = '<' then 'cr.salary < 5000'
when '>' = '=' then 'cr.salary = 5000'
else null
end);
the expression in the when clause of the case-when statement will come from UI and depending on the choice i need to make the where clause.
thats why for running the query, i have put '>' in that place.
so the original query will look like this(for your reference):
select cr.customer_name || ' - ' ||cr.customer_number as cust_name,
cr.salary as salary
from customer_details cr
where (case when variable = '>' then 'cr.salary > 5000'
when variable = '<' then 'cr.salary < 5000'
when variable = '=' then 'cr.salary = 5000'
else null
end);
so, in actual 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 am getting the error "ORA 00920:invalid relational operator"
please help..thanks in advance..

Hi,

How to use case when statements in ODI

I need to put conditional logic before DVM look up in ODI. In the expression editor I put the following statement:-
CASE WHEN POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME='RCS' THEN POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME=EBIZ_CELL.CELL_DATA
WHEN POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME='FDC' THEN CONCAT(POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME,POC_JOURNAL_TEMP_SOURCE_TBL.BOOK_CODE)=EBIZ_CELL.CELL_DATA
END
It did not work,
Under Operators ->All Executions, found the error:-
905 : 42000 : java.sql.SQLException: ORA-00905: missing keyword
The description in Session Task contained:-
select
     C1_JOURNAL_TEMPL
from     APPS.POC_JOURNAL_TEMP_SOURCE_TBL POC_JOURNAL_TEMP_SOURCE_TBL, APPS.C$_0POC_JOURNAL_TEMP_TARGET_TB
where
     (1=1)
And (CASE
WHEN POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME='RCS'
THEN POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME=C2_CELL_DATA
WHEN POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME='FDC'
THEN CONCAT(POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME,POC_JOURNAL_TEMP_SOURCE_TBL.BOOK_CODE)=C2_CELL_DATA
END)
Checked the above code in PL/SQL Developer but it gave errors.
In PL/SQL developer tried to check a simple query using case-when but even that is giving errors in the case-when portion.
The query is as follows:-
select phase_code, accounting_period, sum(eff_cc) as BD_Eff_QTD
from prj_detail
where
case POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME
when 'EXT'
then
1
when 'RAC'
then
2
when 'XXX'
then
3
else
end
I would like to know what is wrong with the above code.
Please let me know what is the correct way of using case-when in PL/SQL as well as in ODI.

Your ODI case statement and PL/SQL Case statement both looks confusing.
You are writing case statement under where clause which is not a good practise. If you want to implement logic like-
select a,b,c from <table>
where
when cond^n^ 1 then do 1
when cond^n^ 2 then do 2
then better you seperate your query for each filter and do a union, in other words-
select a,b,c from <table>
where cond^n^ 1
union
select a,b,c from <table>
where cond^n^ 2
If you are writing case staement to retrieve a value/column (EBIZ_CELL.CELL_DATA) then no need to include it under filter.
ODI case for column EBIZ_CELL.CELL_DATA will be:
CASE
WHEN POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME='RCS'
THEN POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME
WHEN POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME='FDC'
THEN CONCAT(POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME,POC_JOURNAL_TEMP_SOURCE_TBL.BOOK_CODE)
END
Pl/SQL query-
select phase_code, accounting_period,
case POC_JOURNAL_TEMP_SOURCE_TBL.APPLICATION_NAME
when 'EXT'then 1
when 'RAC' then 2
when 'XXX' then 3
else 'default value' --- (if no else needed then can also remove else part)
end,
sum(eff_cc) as BD_Eff_QTD
from prj_detail
Suggested as per what is understood, hope it helps.

But, it was take too long to appear in dashboard, I'm afraid the syntax not proper.
Does anyone know how to show all the data in oracle pl sql / obiee syntax ?

else VALUEOF(NQ_SESSION."LOGIN") end
= upper(substring(Fact_Medication.DOCUMENT_ID_EXT from 1 for 3)
I want if Login variable='All' then show all data, if not then show specific data.
I though my query is right but it takes too long to appear in dashboard.
