Case When instead of Decode

Hi,
How to convert this decode statements into CASE WHEN syntax
phone_v := DECODE (c_rec.phone, NULL, NULL, DECODE ( is_it_number (c_rec.phone), 'F', DBMS_RANDOM.STRING ('a', LENGTH (c_rec.phone)), SUBSTR (DBMS_RANDOM.VALUE, 2, LENGTH (c_rec.phone))));
thanks, Bcj

That should be easiest written like the following :
phone_v := DECODE (c_rec.phone
                  , NULL, NULL
                  , DECODE ( is_it_number (c_rec.phone)
                            , 'F', DBMS_RANDOM.STRING ('a', LENGTH (c_rec.phone))
                            , SUBSTR (DBMS_RANDOM.VALUE, 2, LENGTH (c_rec.phone))
                  );Is it ?

CASE WHEN statement in DECODE

Could you kindly guide us as to how can we use DECODE and get the desired output.
Thanks,
Rami Reddy.

You can, like this.
However, the CASE seems a lot clearer to me so why bother with a DECODE?

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..

CASE..WHEN &a THEN decode(instr(colA,'-') 1,colA,......

Using CASE within a function I wish to apply a second level of criteria within the CASE statement, something along the lines of the following:

Looks nifty but doesn't work. Any suggestions would be appreciated.
Thanks,

Why are you switching to DECODE? Just use CASE again:
case upper(option_in)
when 'P' then case
              when instr(value_in, '-') > 1 then value_in
              else plan_b

CASE instead of DECODE

With the help of the board I wrote a query using the DECODE function to display a full name correctly space with or without a middle name. Could I do that in a CASE statement? I am trying to come up with the best solution. I tried it but know I am missing something - here is what I have so far
Could I do it in a case statement? I am trying to think about the best way to approach this -

Error creating view with CASE -- WHEN statement in SQL*Plus

I am using Oracle 8i 8.1.7
I have an Oracle view which uses CASE...WHEN statements.
The view compiles fine in DBA studio.
Using TOAD I saved the view as an *.sql file.

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

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.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).

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

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)

Need help converting Excel IF statement into CASE WHEN statement for Oracle

Hi,
Hope someone can help I have tried various ways of getting this to work, to no avail!
Bascially I have some figures that are minus figures, and I need to add them together to get a movement figure, but I need to treat the minus figures as minus, if that makes sense, rather than the usual... a minus and a minus makes a plus.
For example:- Budget Figure = -1% and Actual Figure = -68% so the movement needs to be -69%.
The IF statement I have been using in Excel is the following:-
=IF(FO110<0,(FP110-(IF(FO110=0,1,FO110)*-1)),FP110-IF(FO110=0,1,FO110))
Which when using the figures as above = -69%
Cell FO = The Budget Figure
Cell FP = The Actual Figure
However, when I created the CASE statement in Oracle, the figure in the query comes back as -0.67, which is oviously not what I want to happen when both actual and budget are minus figures; however when they are a minus and a plus, it works perfectly fine.
Any help on this would be most appreciated!
Kind regards,
Annmarie

Happy I did'n mess something up :)
Nevertheless, don't show it too much around because
case when budget < 0
     then actual - case when budget = 0 /* will never happen */
                        then 1           /* will never happen */
                        else budget
                   end * (-1)            /* -budget * (-1) remains only */
     else actual - case when budget = 0
                        then 1
                        else budget
                   end
endso at least try the following (if case is more readable as decode for you). Let's hope it works as I don't have a Database at hand
case when budget < 0
     then actual + budget
     else actual - case when budget = 0
                        then 1
                        else budget
                   end

I want to use the case when construct in a trigger instead of the regular select count(*) into statement to check the existence of a row but it does not work. I have used this extensively when I generate XML from many tables in a sproc and they work beautifully. Here is my code from the trigger.
if :new.charge_conditions in ('DAB', 'DOB', 'IMB') then
                              /*     -- do not know why the case does not work here! 12/04/2006
               case
                    when (select count(*) from boarder_date
                         where booking_no = :new.booking_no) <= 0 then
                         insert into boarder_date(booking_no, start_date)
                         values(:new.booking_no, sysdate);
               end ;
               select count(*) into v_boarderCount from boarder_date
                    where booking_no = :new.booking_no;
               if v_boarderCount <= 0 or v_boarderCount is null then
                    insert into boarder_date(booking_no, start_date)
                    values(:new.booking_no, sysdate);
               end if;
          end if;
The error message is this,
PLS-00103: Encountered the symbol "SELECT" when expecting one of
the following:
( - + case mod new not null others <an identifier>
<a double-quoted delimited-identifier> <a bind variable> avg

PLS-00103: Encountered the symbol ")" when expecting one of the
following:

I have to use select count(*) into to make it work. Is that not allowed in a trigger or did I do something wrong with the syntax here? Thanks a lot.

I don't believe that you can use the result of a query in a CASE statement in PL/SQL like you can in SQL. While it's perfectly valid to have
1 select case when (select count(*) from emp) > 1
2              then 1
3              else 0
4          end

Update multiple rows using CASE WHEN

I have the table ACCOUNT of structure as follow:
ACCOUNT_ID
ACCOUNT_STATUS
004460721
2
042056291
5
601272065
3
I need to update the three rows at once using one SELECT statement such that, the second column will be 5, 3, 2 respectively.
I used the following query but seems there is something missing
UPDATE ACCOUNT
SET ACCOUNT_STATUS = CASE
WHEN ACCOUNT_STATUS = '004460721' THEN 5
WHEN ACCOUNT_STATUS = '042056291' THEN 3
WHEN ACCOUNT_STATUS = '601272065' THEN 2
WHERE ACCOUNT_ID IN ('004460721','042056291','601272065')
My question, is this way correct? if no, can I use CASE WHEN statement and how or I only have choice of using SUB-SELECT to acheive that in one statement?

What happens when you try it?
Did you mean "WHEN ACCOUNT_ID = ..."?
A CASE expressions always needs an END keyword.
Depending on your requirements (that is, why are those rows being changed, and how do you determine the new values) a CASE expression in an UPDATE statement, similar to what you posted, could be a good way to do it. MERGE (instead of UPDATE) would also be an option, especially if you want to avoid updating rows that already happen to have the correct values.

Case When instead of Decode
