Help Regarding CASE Statement.

hey !
i m trying to apply COUNT to a column , with a particular condition.
like.
CASE
WHEN( A > B)
THEN COUNT(some column)
else '0'
end
but its not working.
can anyone tell me how to count only particular rows which satisfy the given condition in WHEN Clause.
i m trying to add many columns from different tables by joining them and then adding column one by one satisfying different conditions.
my final table looks like this.
items in stock-----|-----items_not_in_STock----|----Items_fully_in_stock
its something like this...!!!
secondly , what if i dont want any ELSE condition.
is it possible???

I am not quite sure I understood your "requirement"...no tables, no sample data, no expected output...
can anyone tell me how to count only particular rows which satisfy the given condition in WHEN ClauseAssuming your requirement is above i.e. getting count of resultset based on different conditions, following might help you.
SQL> select sum(case when object_id > 10000 then 1 end) from t ;
SUM(CASEWHENOBJECT_ID>10000THEN1END)

I am applying rules on col3 and col4 for each records row-wise.
I need case statements to populate status and reason columns after applying below rules
Rules
Col3 :
For A record ,it should be 12345 always .
For B,C,D,E , record should be always 1
col4
For A record , it should be either P or R
No null values for all A, B,C,D,E records
for B record , it dont contain special charecters
for C RECORD , it dont contain special charecters
for D record ,it should not contain future dates (dates are in yyyymmdd format and less than sysdates are valid )
I have other columns as well ,as i not included here
.It would be great if you Could help on case statements
Thanks and Regards,

             case when (col2 = 'A'        AND col4 not IN ( 'P', 'R' ) )

Regarding case statement and decode function

Hi Experts,
I have question.....regarding case statement and decode statement....
Can you please explain me that which one will be efficient,to place in insert statement...
insert statement(
(case when ........then
                     case when ....then
                     else
                     end)
else
end)
or
insert statement(
case when.....then
decode(....)
else
end)
Can you people explain me which one is more efficient method?
Thanks in advance.......

The are major differences to talk about in case of CASE vs DECODE, but performance wise both are pretty much the same.
Have a look at Tom's thread
Ask Tom &quot;better performance - case or decode&quot;
I would suggest to use CASE whenever possible. Don't worry about the performance part.

Just a FYI regarding Case statements in ORacle 8i in pl/sql

Well..I saw numerous posts in this forum regarding not being able to do case statement within pl/sql. Well..you can do
that using dynamic SQL. IT works like a champ.

Hi,
Try first to (re)compile ll invalid objects. then
you can run:
select owner,type,count(*) from all_errors
group by owner,typeif you still have uncompiled objects, then report the different errors:
select * from all_errors...

Hi all
I'm stuck on scenario. I have query something like this

now I'm trying to return ENAME (TARGET_CODE) that I use in my Case but I'm getting error. I don't know why. Please guide me.

I don't understand your query at all, so I'm just taking a guess here:
SQL> select m.emp_no
2        ,m.hire_date
3        ,m.e_name
4        ,d.pl_code
5 from   emp_mst m
6 left   join
7              (select emp_no, pl_code
8               from   emp_dtl
9               where (
10                          (emp_no = 10 and pl_code = 'BB')
11                       or (emp_no in (20,30) and pl_code = 'LOB')
12                      )
13              ) d
14              on (d.emp_no = m.emp_no)
15 ;
EMP_NO HIRE_DATE    E_NAME   PL_CODE

EDIT: changed the query.

Need Help:Regarding Case when we should receive an email if we haven't receive feed within SLA.

Hello Cisco Team/Everyone,
We are facing one major hurdle we need to configure a case when a email should be sent to business if the feed is not received within SLA.
At present what we can configure is if feed is being received within SLA then an email will be sent informing about the timely delievery of feed and if we receive feed after SLA then also an email will be sent to business informing that feed received late but if we haven't received the feed within SLA then please let us know how to configure Email Action ? ( informing that we haven't received the feed within SLA )
Thanks.

You have muliple solutions so we probably need more details
At a mininum you would want 2 different email events with different triggers and 2 different email actions
You may or may not have 2 different jobs
How we decided to handle:
We decided to create and ALERT Job Group for our SLA notifications/alerts
   (you can make it its own parent or integreate with another Job Group depeending on what makes sense to you)
We organized the next level by time windows in military time
Alert\
\0000_0259 <-- alerts that trigger between midnight and 3am (they line up top to bottom that way and visually progress)
If this is a file based alert you create a dependecy on the file not existing
Next put a Time Window on it lets say start at 12:15am and end at 1:00 am
Here's the counter intuitive part:
You create an event to send an email to business on job completed normally that the SLA was breached
          if the file didn't exist by 1am then this executes and completes normally
          We use powershell to write-output of text we want to send for that particular business unit
          We use in email action
You create an event to skip the job if job not ready by the end of its time window
          if the file existed then the depdendcy is not statisfied and job essentailly is not ready by end of time window 1am
          Operations teams consider "skipped" a "OK" status since we do it on purpose
Other options
You could also use exit codes to do similar things, if your process that is evaluating the SLA is produce different exit codes, Then you can apply different events to the exit codes
Hope that helps!
Marc

Need help in this query using Case Statement

I have the following query which is currently existing and I am adding few more conditions based on the new requirements which is based on a particular flag set as 1 or 0.
If it is set to 1 then I should use the old query as it is and if it is set to 0 then I should add the new conditions.
Basically when the flag is set to 0, I shouldnt be including some of the records that already exists and should include only new records. This is based on the plan_type_ids in (1,2,3,4).
Hence I am using the Case statement to check if the plan_type_id is in (1,2) then do a set of not exists and if the plan_type_id in (3,4) then do set of not exists.
But when I run this query it is giving me error. What am I doing wrong?
Is there any other simple way to combine all the not exists for all of those select statements as given after the line ------------------------- into a single one?
What am I doing wrong?
I tried putting the NOT EXists before the case too but that too didnt work.
Please help. Appreciate it.
Thank you in advance.

Help: How to use Case statement in Interface ODI11g?

Hi
From my Source base i am getting 'Year' Values and i want translate these values into a code in interface and after translate want to push to Target system.
Example:
From source Database i am getting value for
Year
2010
2011
2012
When i get Year 2010 i want to modify value into 'FY10'
when i get Year 2011 i want to modify value into 'FY11'
and same for Year 2012 TO 'FY12'
I was trying to do by Case statement but didn't got success.
I dont want to create Lookup table in source system.
Any help in this regards.
Thanks
Regards
Sher

WHEN source_column='2010' THEN 'FY10'
WHEN source_column='2011' THEN 'FY11'
WHEN source_column='2012' THEN 'FY12'

Please help: Case Statement - ORA-01722: invalid number Error

Hi All,
I'm trying to use Case statement to recode Cancelled statuses into two groups
'Reject' if the difference between first date and last date is less than 29 and
'Accept' if the difference between first date and last date is greater than 30
Here is my 'test' data:
STATUS     FIRST_DATE     LAST_DATE
Transfer     10/08/2011     10/09/2011
Mover     10/08/2011     15/09/2011
Cancel     10/08/2011     16/09/2011
Cancel     10/08/2011     5/09/2011
Here is the syntax
select a.*,
(CASE WHEN a.STATUS ='Cancel' THEN (round(a.LAST_DATE-a.FIRST_DATE))
ELSE 0
END) CAN_DAYS,
(CASE WHEN 'CAN_DAYS' >29 THEN 'Reject'
WHEN 'CAN_DAYS' <30 THEN 'Accept'
END) Reject_Accept
from test a
The first CASE statement works fine and gives me this
STATUS     FIRST_DATE     LAST_DATE     CAN_DAYS
Transfer     10/08/2011     10/09/2011     0
Mover     10/08/2011     15/09/2011     0
Cancel     10/08/2011     16/09/2011     37
Cancel     10/08/2011     5/09/2011     26
but the second CASE produces ORA-01722: invalid number Error. It is something to do with the CAN_DAYS data type, Oracle doesn't see it as Numeric i think.
The result i want to see would be
STATUS     FIRST_DATE     LAST_DATE     CAN_DAYS Reject_Accept
Transfer     10/08/2011     10/09/2011     0
Mover     10/08/2011     15/09/2011     0
Cancel     10/08/2011     16/09/2011     37 Accept
Cancel     10/08/2011     5/09/2011     26 Reject
Could someone please help me to fix the syntax?
Thank you in advance,

This seems to give you your desired results...

Need help in this sql query to use Case Statement

hi All,
I have the below query -
SELECT DISTINCT OFFC.PROV_ID
,OFFC.WK_DAY
,CASE
WHEN OFFC.WK_DAY ='MONDAY' THEN 1
WHEN OFFC.WK_DAY ='TUESDAY' THEN 2
WHEN OFFC.WK_DAY ='WEDNESDAY' THEN 3
WHEN OFFC.WK_DAY ='THURSDAY' THEN 4
WHEN OFFC.WK_DAY ='FRIDAY' THEN 5
WHEN OFFC.WK_DAY ='SATURDAY' THEN 6
WHEN OFFC.WK_DAY ='SUNDAY' THEN 7
END AS DOW
,OFFC.OFFC_OPENG_TIME
,OFFC.OFFC_CLSNG_TIME
FROM GGDD.PROV_OFFC_HR OFFC
WHERE OFFC.PROV_ID='0000600'
WITH UR;
this query is bringing results in 6 differnt rows with opening and closing time for each day separately. I want to generate the data in one row with each day having opening and closing time, so for 7 days, total 14 columns with opening and closing time. But i am not able to do that using case statement.
can somebody help me in achieving that.
thanks,
iamhere

Hi,
Welcome to the forum!
That's called a Pivot .
Instead of having 1CASE expression, have 14, one for the opening and one for the closing time each day, and do GROUP BY to combine them onto one row.
SELECT       OFFC.PROV_ID
,       MIN (CASE WHEN OFFC.WK_DAY ='MONDAY'    THEN OFFC.OFFC_OPENG_TIME END)     AS mon_opn
,       MIN (CASE WHEN OFFC.WK_DAY ='MONDAY'    THEN OFFC.OFFC_CLSNG_TIME END)     AS mon_cls
,       MIN (CASE WHEN OFFC.WK_DAY ='TUESDAY'   THEN OFFC.OFFC_OPENG_TIME END)     AS tue_opn
,       MIN (CASE WHEN OFFC.WK_DAY ='TUESDAY'   THEN OFFC.OFFC_CLSNG_TIME END)     AS tue_cls
FROM        GGDD.PROV_OFFC_HR OFFC
WHERE       OFFC.PROV_ID     = '0000600'
GROUP BY offc.prov_id
;This assumes there is (at most) only one row in the table for each distinct prov_id and weekday. If not, what do you want to do? Post a little sample data (CREATE TABLE and INSERT statements) and the results you want from that data.
The staement above works in Oracle 8.1 and up, but there's a better way (SELECT ... PIVOT) available in Oracle 11. What version are you using? (It's always a good idea to include this when you post a question.)
