How to use CASE or DECODE in this?

Hi , I have a query like this
AND ...smthng
AND --smtg
AND age BETWEEN ....For the last AND clause for age column, I have the values passed from IN param of this SP in form of strings
'0-30', '31-60', '61-90', and '91+'. The IN param is of course VARCHAR2.
What I want to do in this AND clause
e.g. for age range '0-30', the AND clause should be
AND age BETWEEN ( if this range is '0-30' then ) 0 AND 30 ( if range is '31-60') then BETWEEN 31 AND 60.. and so on...
However this BETWEEN will work till 61-90 range but for 91+ , there is no upper bound so it should be
AND age>91
Now , i am not sure how to achieve this both BETWEEN and '>' clauses in the same AND statement.
DECODE will not work and am not sure how to use the CASE in this situation as even that can not solve this issue.
Dont want to make the last AND clause dynamic
Please suggest me how to do this.
Thanks,
Aashish

A third alternative would be to choose a suitably large value as a high end for the 91+ group and use something like:
age between to_number(CASE WHEN instr(:param, '+') = 0
                              THEN substr(:param, 1, instr(:param, '-') -1)
                              ELSE substr(:param, 1, instr(:param, '+') -1) end) and
            to_number(CASE WHEN instr(:param, '+') = 0
                           THEN substr(:param, instr(:param, '-') +1)
                           ELSE '9999' END)John

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;

How to use CASE stmt in Where clause

Hi,
How to use CASE stmt in WHERE clause?. There's no difference between how a CASE expression is used in a WHERE clause, and how it is used in any other clause. CASE ...

CASE expressions aren't needed in WHERE clauses very much. The reason CASE expressions are so useful is that they allow you to do IF-THEN-ELSE logic anywhere in SQL. The WHERE clause already allows you to do IF-THEN-ELSE logic, usually in a more convenient way.
I need the code.So do the peple who want t help you. Post a query where you'd like to use a CASE expression in the WHERE clause. Post CREATE TABLE and INSERT statements for any tables used unless they are commonly available, such as scott.emp). Also, post the results you want from that sample data, and explain how you get those resuts from that data.
See the forum FAQ {message:id=9360002}
Please send me as early as possible..........As mentioned bfore, that's rude. It's also self-defeating. Nobody will refuse to help you because you don't appear pushy enough, but some people will refuse to help you if you appear too pushy.

How to use, Case function and Filter in Column Formula?

Hello All,
I am using case function and also would like to filter value to populate.
Below is showing error :
case
when '@{Time}' = 'Year' then "Time"."Fiscal Year"
when '@{Time}' = 'Quarter' then "Time"."Fiscal Quarter"
when '@{Time}' = 'Month' then FILTER ("Time"."Fiscal Period" USING "Time"."Fiscal Period" NOT LIKE 'A%')
else ifnull('@{Time}','Selection Failed') end
Thanks, AK

when '@{Time}' = 'Month' then FILTER ("Time"."Fiscal Period" USING "Time"."Fiscal Period" NOT LIKE 'A%')I dont think Filter this works here or any other data types except number.
Try to use option Column's->Filter->Advanced->Convert this filter to SQL

How to use case when statements in ODI

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:-

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.

How to use logic:interate tag in this case? thanks a lot.

a javabean:
a{
int a;
ArrayList bList (to store some strings);
request.setAttribute("a",a);
then how can I use <logic:iterate> tag to loop to use <bean:write> tag to write out the strings contained by bList?

use getparams and get that attribute(arraylist)
define a bean in jsp with property as this attribute for which u should have a getter method in context
the following is to iterate through arralist of arraylist
<logic:iterate id="accList" name="<%=subAppContextName%>" ="accountsHoldedList">
<tr>
<logic:iterate id="accList2" name="accList">
<td> <bean:write name="accList2"/> </td>
</logic:iterate>
<td>
<jfp:link styleClass="appNavNext" warn="false" bundle="<%=bundleName%>" key="GiveNotice" paramId="selectedAccount" paramName="accList2" href="javascript:submitMyForm();"></jfp:link>
</td>
</tr>
</logic:iterate>
accountsHoldedList is the one which is set in Context and i am iterating to display it.
