Help With A Case Statement With Multiple Variables

I apologize if this is the incorrect Forum for this type of question, but it was the closest one that I could find. I'm pretty new with SQL and am stuck on this issue. I have roughly 26 dates that I need to compare to one another. Each date is tied to a step code. I also have a Stop value that is tied directly to the "max date" of the step codes. So, I need to compare 30 dates against one another to 1st - ID the max date; 2nd - ID if the Stop value is correct; 3rd - if the stop value is incorrect, identify what the correct value would be.
At first, this seemed like it wouldn't be that hard. I wrote a query that found the max date for each step code. Then I realized that multiple step codes could have the same date. So, I tried using this case statement, but I did not get the expected results. Is there a more efficient way of getting what I need? This code seems like it's not necessary and probably the source of my issue.
CASE
WHEN FS25.ACTUAL_COMPLETION_DATE > FS.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS1.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS2.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS3.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS4.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS5.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS6.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS7.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS8.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS9.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS10.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS11.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS12.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS13.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS14.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS15.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS16.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS17.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS18.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS19.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS20.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS21.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS22.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS23.ACTUAL_COMPLETION_DATE AND FS25.ACTUAL_COMPLETION_DATE > FS24.ACTUAL_COMPLETION_DATE AND L.FORECLOSURE_STOP_CODE <= '8' THEN '9'
ELSE 'UH OH'
END AS "CHANGE FC STOP TO"
Any assistance is appreciated!

I think Igor pointed out a working solution before.
Applying it at your examples (you missed the operator after STOP_CODE, I assume it =):
CASE
WHEN FS25 = GREATEST(FS25, FS24, FS23) AND STOP_CODE = '9' THEN '9'
ELSE 'UH OH'
END AS 'CHANGE STOP CODE TO'
{code}
Be careful at the second example. You are checking:
{code:sql}
FS25 > FS24 OR FS25 IS NOT NULL AND FS24 IS NULL AND FS25 > FS23
OR
FS25 IS NOT NULL AND FS23 IS NULL AND STOP_CODE = '9'
{code}
Remember that AND has higher priority among operators than OR so if FS25 is greater than FS24 and FS23 the condition will be true even if STOP_CODE is not equal 9.

Help with a CASE statement

Please help me with a CASE Statement:
- When ID = 15, 16, 17, 18 then "Bad"
- when ID = 19, then "Average"
- when ID = 21, then "Good"
- else "Null"
Thank you!!

Well the 1st thing to do would be to correct my poor spelling... change    Delault : to Default :
Don't know why you would get an error stating "The result of selection formula must be a boolean". It's working fine on my machine.
If your ID field is numbers stored text you have a couple different options...
1) Convert the ID to a number...
Select ToNumber({home.noone_ID})
2) Wrap the ID values in double quotes...
   Case "15", "16", "17", "18" :
      "BAD"
Even if this were your problem... the error should be something other than the boolean thing...

Be more specific. Post a complete script that you tried, and what output you expected from it. If you got an error, post the complete error message, including line numbers.

/If the condition involves a query, then you may have to select the results into a variable first, and then use the variable in the CASE statement.

Case statement with having null gives default result

Hello,
When we write a case statement with a not equal condition <> on a column and if that columns has null value the it gives the else value.
eg
Select Column_Name, Case when Column_Name <>Condition then 0 else 1 end as case_test from Table_Name.
Ideally null is not equal to the condition so the case should return 0 but it returns 1. Can anyone tell me why?

In addition to the other posts:
NULL is an unknown value, when you say
col <> 1
and col is NULL, we don't know whether col is 1 or something else. Thus the condition evaluates to UNKNOWN. How UNKNOWN is handled depends on the context. In WHEN clauses as well as the IF statments, the effect that the code bracketed by IF/WHEN is not
entered. That is, UNKNOWN and FALSE yields the same result. In CHECK constraints, it's the other way round. If you have
CHECK (WHEN col <> 0)
rows where col is NULL are accepted.
When you work with SQL, no matter the database product, it's imperative to master three-valued logic, because it comes up all the time.
As I said, NULL is the unknown value. In practice, NULL has a distinct interpreation depending on the database column. For instance, NULL in a column called EndDate, usually means that the period (or whatever it is) is still open. So often when you work
with NULL values you use isnull to replace it with some value that fits the context, and finding that value takes some consideration. Blindly doing isnull(col, '') can lead to serious bugs, particularly if col is not a string column.

Need some help with a case statement implementation

I am having trouble using a CASE statement to compare values and then display the results. The other issue is that i want to put these results in a separate column somehow.
Heres how the code would look:
SELECT "Task"."Code",
"Stat" = CASE WHEN "Task.Code" = 1 THEN string
....and so on
I wanted to make "Stat" the new column for the results, and string represents the string to be assigned if 1 was the value for code. I keep getting syntax error, any help would be nice.

This is a lot easier than you might think.
1) First, move another column of "Code" to your workspace.
2) Click on the fx button and then on the BINS tab.
3) Click on "Add BIN" and with the operand on "is equal to/is in," input 1 and then click "OK."
4) Name this what you had for "string."
Repeat for all the different values you want to rename as another "string" value.
5) Finally, check the "custom heading" checkbox, and rename this column "Stat" as you indicated.
That's it.

Help with Switch-Case Statement

How do you get this in a switch-case statement or work with it?

          else if (age > 79 && age < 90) {
                    JOptionPane.showMessageDialog(null, "People that are in their 80s are called octogenarian.");
          else if (age > 89 && age < 100) {
                    JOptionPane.showMessageDialog(null, "People that are in their 90s are called nonagenarian.");
          else (age > 99 && age < 110) {
                    JOptionPane.showMessageDialog(null, "People that are in their 100s are called centenarian.");
               }Thanks~

As per Java Specification, swtich case expects an integer and boolean cannot be used as param for switch.
In your case switch can be used like this.
int index = age /10;
switch(index) {
case 1:
case 2:
case 3:
case 4:
case 5:
case 6:
Your First case
break;
case 7:
your second case
break;
case 8:
third case
break;
case 9:
fourth case
break;
default:
fifth case
break;
Take note of the break statements. Its very important. But I wont prefer in this case. Code looks awkward and is not so meaningful.....

You are getting the "Not a group by expression" error because you are not using in aggregate functions in your select statement. (You are using the aggregate function SUM in the second query)
The "not a a single-group group function" means you are returning multiple rows of a data when it only expects one.

Hi,
Never write, much less post, unformatted code.
Indent the code to show the extent of multi-line structures like BEGIN and CASE.
For example:
DECLARE
     /* Set supported version here */
     ora_version       VARCHAR2 (4);
     unsupp_version       EXCEPTION;
     /* Archive Log Info */
     db_log_mode      VARCHAR2 (12);
BEGIN
     SELECT     SUBSTR(VERSION, 1, 4)
     INTO     ora_version
     FROM     v$instance;
     SELECT     log_mode
     INTO     db_log_mode
     FROM     v$database;
     CASE
         WHEN ora_version = '10.2' THEN
          DECLARE
              TYPE t_db IS RECORD(
                         dflsh     VARCHAR2(3),
                         dcscn      NUMBER);
              v_db t_db;
          BEGIN
              CASE
                  WHEN db_log_mode = 'ARCHIVELOG' THEN
                   EXECUTE IMMEDIATE 'SELECT INITCAP(flashback_on), current_scn FROM v$database'
                                       INTO v_db;
                   DBMS_OUTPUT.PUT_LINE(' Flashback On : ' || v_db.dflsh);
                   DBMS_OUTPUT.PUT_LINE(' Current SCN : ' || v_db.dcscn);
                   DBMS_OUTPUT.PUT_LINE(' Log Mode : ' || db_log_mode);
                   DBMS_OUTPUT.PUT_LINE(' Version : ' || ora_version);
              END;
...The code above is what you posted, with some whitespace added.
The error is much clearer; the last CASE statement concludes with END, but CASE blocks always have to conclude with END CASE .
Why are you using a nested BEGIN block in the code above? Are you plannning to add an EXCEPTION handler later?

Hi,
So, you don't want to ignore the whole row when stat != 'E' (that would ignore the only row with id='3'). Putting the condition 'stat = 'E' in the WHERE clause sill ignore the row, so that's not what you want.
You just want to ignore the term column. Put the same condition in a CASE expression that only contols that column.
Here's one way:
SELECT       id
,       MIN ( CASE
                 WHEN stat = 'E'
              THEN     term
             END
           )          AS min_e_term
FROM      dan_gr2
GROUP BY id
ORDER BY id

CASE Statement for Multiple Criteria

Hello,
I need to write a query that will give me a count of customers that fall in three different categories:
< 1 year
1 to 3 years
3 yearsI have written the code to bring me back the 1st set of criteria (< 1 yr). I am using the date connected to a customer's account(s) to return the oldest date attached to an account to put that customer in the appropriate bucket. Below is the code I have for the first piece:
SELECT COUNT(*) AS One_Year_Or_Less
FROM
(SELECT c.lname||', '||c.fname AS Name, MIN(a.contractdate) AS ContractDate
FROM account a, customer c
WHERE a.custnbr = c.custnbr
GROUP BY c.lname, c.fname) yr
WHERE yr.contractdate BETWEEN TO_DATE('03/02/2005', 'MM/DD/YYYY')
AND SYSDATE
The above query runs and returns what I beleive to be an accurate count of customers who fall in the 1 year or less range. My question is; how can I add the criteria of 1 to 3 years and > 3 years to this query. I need to have 3 seperate columns (or 3 seperate rows) that contain the heading of the specific criteria and then the count for that criteria. I was thinking of trying to use a CASE statement but I am unsure of exactly how to do that. Perhaps I could somehow create 3 seperate sub-queries to acheive my goal. Any help with this issue will be greatly appreciated. Thank you.
Dave Y

Here's another way. It will only count those that meet the criteria, otherwise it will sum a 0. If you just want 1 row returned with the counts, there's no need for a GROUP BY
SELECT SUM(CASE
               WHEN contractdate > add_months(sysdate,-12) THEN 1
               ELSE 0
           END) less_than_1_year
      ,SUM(CASE
               WHEN contractdate >= add_months(sysdate,-36)
               AND contractdate <= add_months(sysdate,-12) THEN 1
               ELSE 0
           END) from_1_to_3_years
      ,SUM(CASE
               WHEN contractdate < add_months(sysdate,-36) THEN 1
               ELSE 0

Need help to write case statement

Hi Guys,
I have dashboard in which its has pprompt called PROPMT1 in that prompt it has three values A,B,C
but iwant the full abbreviation of those values like A=APPLE B=BOY and C=Cindy
and also in the report i have the coloumn is prompted by PROMPT1 which has again A,B,C values that need to be modified as A=APPLE B=BOY and C=Cindy
how can i do it with case statement.

For the prompt, write this in the Show window>SQL Results:
1) CASE WHEN 1=0 THEN char_columnname ELSE 'A = APPLE' END FROM "your subject area" UNION ALL CASE WHEN 1=0 THEN char_columnname ELSE 'B = BOY' END FROM "your subject area" UNION ALL CASE WHEN 1=0 THEN char_columnname ELSE 'C = Cindy' END FROM "your subject area"
2) Save the prompt to a presentation variable, pv_choice
This will give you your three values. Make sure you use a CHAR column, doesnt matter what column, though.
For the report,
1) Create a BINS column on the column that contains the A, B, C values and make the BINS A = APPLE, B = BOY, C = Cindy just like the prompt values.
2) Now put a filter on this BINS column and set it equal to your pv_choice presentation variable.
That's it.
NOTE: Obviously, if you want the prompt values to just say "APPLE," "BOY," and "Cindy," then take off the 'A = ', 'B = ' and 'C = ' appropriately. Same for the BINS in your report.

Please tell me why the query below is always returning the bold null even when the start_date of OLD is greater than or equal to the start_date of NEW.
What I want to do is get the difference of the start_dates of two statuses ( Start_date of OLD - Start_date of NEW) if
1. end_date of NEW is not null
2. start_date of OLD is greater than start_date of NEW
else return null.
select id,
case when max(end_date) keep (dense_rank last order by decode(request_wflow_status,'New',1,0),start_date) is null then
null
else
          case when max(decode(status,'OLD',start_date,null)) > max(decode(status,'NEW',start_date,null))
          then max(decode(status,'OLD',start_date,null)) - max(decode(status,'NEW',start_date,null))
else
null
end
end result
from cc_request_status where id =1
group by id;

Avinash,
Thank you for your help.. Here is a more description of my problem..
Here is a sample of data I have for a table with four columns (id,status,start_date,end_date)
What I need to do is to get difference of the start dates of the maximum available dates, if data is valid. The pseducode is as follows:
IF end_date of New status is null
THEN return null
ELSE
IF start_date of old >= start_date of new
THEN return (start_date of old - start_date of new)
ELSE return null
I used the following query but always return the bold null
select id,
(case when max(end_date) keep (dense_rank last order by decode(status,'new',1,0),start_date) is null then
null
else
          (case when max(decode(status,'old',start_date,null)) >=
          max(decode(status,'new',start_date,null))
          then max(decode(status,'old',start_date,null)) - max(decode(status,'new',start_date,null))
else
null
end)
end) result
from tbl where id =1
Based on the below sample, I expected to get the following result; 14-Mar-07 - 16-Feb-07 which is the difference of the maximum start_dates of the two statuses. However the query is not working.. Please help me.. Thank you..
Id    Status    start_date      end_date
1     new      03-Feb-07      07-Feb-07
1     new      16-Feb-07      21-Feb-07
1     old      '10-Mar-07      12-Mar-07
1     old      '14-Mar-07      16-Mar-07
