Help in changing plsql case when to decode
Hi,
Can anyone help me to change this sql for it to use decode function instead of case when? Below is the sql code
Thanks in advance.
SELECT
parts,
weeks,
SUM(qty) qty
FROM (
SELECT
CASE
WHEN ((is_tbd = 'yes' AND is_tbd_order = 'no') OR ex_fac_date > v_asofdate + 131) THEN 'tbd'
WHEN ex_fac_date BETWEEN v_asofdate - 1 AND v_asofdate + 5 AND is_tbd = 'no' THEN 'wk1'
WHEN ex_fac_date BETWEEN v_asofdate + 6 AND v_asofdate + 12 AND is_tbd = 'no' THEN 'wk2'
WHEN ex_fac_date BETWEEN v_asofdate + 13 AND v_asofdate + 19 AND is_tbd = 'no' THEN 'wk3'
WHEN ex_fac_date BETWEEN v_asofdate + 20 AND v_asofdate + 26 AND is_tbd = 'no' THEN 'wk4'
WHEN (ex_fac_date < v_asofdate - 1) AND is_tbd = 'no' THEN 'past_due'
END weeks,

Hi Experts,
Actually i have a requirement where i have to change the case of a selected word by a user into upper case.
ex: FFFFFF hhhhh GGGG

Need help with changing letter cases : (
Hey everyone, I have an assignment that needs to
1) allow the user to enter a sentence
2) count the number of upper case, lower case, spaces, and other characters in the sentence,
3) convert each first letter of a word into upper case if not already in upper case,
4) convert non first letters to lower case if not already in lower case
So, I have been successfull counting all characters, but I can't seem to find a way to convert the letter cases.
I understand I have to distinguish first letters and non first letters, and I did this by using a boolean.
Also, I tried to use a for loop and convert the letter cases accordingly by += 32 and -= 32.
This is what I have for now :
import javax.swing.JOptionPane;
public class Asg3 {
public static void main(String [] args) {
String sentence = JOptionPane.showInputDialog("Enter a Sentence!");
int length = sentence.length();
int counter = 0;
int uppercase = 0;
int lowercase = 0;
int space = 0;
int other = 0;
int total = 0;
boolean firstletter = true;
char thischarac;
for (counter = 0; counter < sentence.length(); counter++)
thischarac = sentence.charAt(counter);
if ( thischarac >= 65 && thischarac <= 90 ) {
++ uppercase;
else if ( thischarac >= 97 && thischarac <= 122 ) {
++ lowercase;
else if ( thischarac == 32) {
++ space;
else {
++ other;
++ total;
for (counter = 0; counter < sentence.length(); counter++) {
thischarac = sentence.charAt(counter);
if (firstletter == true) {
if (thischarac >= 97 && thischarac <= 122) {
thischarac -= 32;
else
if (firstletter == false)
if (thischarac >= 65 && thischarac <= 90) {
thischarac += 32;
System.out.println("You have entered: " + sentence);
System.out.println("Upper case Letters: " + uppercase);
System.out.println("Lower case Letters: " + lowercase);
System.out.println("The number of blank spaces: " + space);
System.out.println("The number of other characters: " + other);
System.out.println("Grand total: " + total);
System.exit( 0 );
I am stuck on this for hours now, and all googling, asking friends, going over lectures have failed, and this is my last resort.
I understand it is frustrating when students come here for homework, but I would really appreciate any hints or help.
Thank you!Oh, sorry I'm new and didn't realize the code button. Anyways, here it is
import javax.swing.JOptionPane;
public class Asg3 {
public static void main(String [] args) {
String sentence = JOptionPane.showInputDialog("Enter a Sentence!");
int length = sentence.length();
int counter = 0;
int uppercase = 0;
int lowercase = 0;
int space = 0;
int other = 0;
int total = 0;
boolean firstletter = true;
char thischarac;
for (counter = 0; counter < sentence.length(); counter++)
thischarac = sentence.charAt(counter);
if ( thischarac >= 65 && thischarac <= 90 ) {
++ uppercase;
else if ( thischarac >= 97 && thischarac <= 122 ) {
++ lowercase;
else if ( thischarac == 32) {
++ space;
else {
++ other;
++ total;
for (counter = 0; counter < sentence.length(); counter++) {
thischarac = sentence.charAt(counter);
if (firstletter == true) {
if (thischarac >= 97 && thischarac <= 122) {
thischarac -= 32;
else
if (firstletter == false)
if (thischarac >= 65 && thischarac <= 90) {
thischarac += 32;
System.out.println("You have entered: " + sentence);
System.out.println("Upper case Letters: " + uppercase);
System.out.println("Lower case Letters: " + lowercase);
System.out.println("The number of blank spaces: " + space);
System.out.println("The number of other characters: " + other);
System.out.println("Grand total: " + total);
System.exit( 0 );
}The problem I'm having is converting letters to their right cases. I need to change the first letters of a word to upper cases, and non first letters to lower cases. For example, if the sentence the user entered is
"tHIS AssigNMent IS harD!" , I would have to convert it to : "This Assignment Is Hard!"
What I tried to do is use a for loop and a boolean.
If firstletter == true, and if the character was lower case, I would subtract 32 from that character.
If firstletter == false, and if the character was upper case, I would add 32.
The problem here is that, what do I have to do to make it print the converted sentence? I have tried System.out.println( "The new sentence is :" + sentence); which gives me only the original sentence,
and System.out.println("The new sentence is :" + thiscarac); which gives me all capital letters.
So there are two main problems:
1) Is my forloop and boolean correct in converting the cases? Am I using the right method?
2) If so, how do I get the system to printout the new converted sentence?

Hi everybody,
I have column in Discoverer like this one shown bellow:
DECODE(Vrstapolise,1,'Aktivno',4,'Kapitalisano',3,DECODE(Stanjepreisteka,'Aktivno','Aktivno','Kapitalisano','Kapitalisano',NULL),NULL)
I want to make the same column with same functionality in OBI BMM. Is it possible? If it is possible, how to do that?
Thanks in advance.As Sai said use Case stmt, your code will something like this
Case Vrstapolise
When 1 then 'Aktivno'
When 4 then 'Kapitalisano'
When 3 then
Case Stanjepreisteka
when 'Aktivno' then 'Aktivno'
when 'Kapitalisano' then 'Kapitalisano'
else Null end
else Null End
Thanks,

Please Help: Trouble with nested CASE statement and comparing dates
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

end
end result

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

Case when statement not working
hi there, I am trying to work out how to get my case statement to work.
I have got the following code.
select pthproto.pthdbo.cnarole.tpkcnarole, pthproto.pthdbo.cnaidta.formataddr as formataddr, cnaidta.dateeffect as maxdate, isnull(cast (pthproto.pthdbo.cnaaddr.prefix1key as varchar (50)),'') + ' ' + isnull(cast (pthproto.pthdbo.cnaaddr.prefix2key

as varchar (100)),'') + ' ' + isnull (cast (pthproto.pthdbo.cnaaddr.component2 as varchar (100)),'') + ' ' + isnull (cast (pthproto.pthdbo.cnaaddr.component3 as varchar (100)),'') + ' ' + isnull (cast (pthproto.pthdbo.cnaaddr.component4
as varchar (100)),'') + ' ' + isnull (cast (pthproto.pthdbo.cnaaddr.component5 as varchar (100)),'') as mailaddress, row_number() over(partition by pthproto.pthdbo.cnarole.tpkcnarole order by cnaidta.dateeffect desc) as rn into #address from pthproto.pthdbo.cnarole
inner join pthproto.pthdbo.cnaidty on cnarole.tfkcnaidty =cnaidty.tpkcnaidty inner join pthproto.pthdbo.cnaidta on cnaidty.tpkcnaidty = cnaidta.tfkcnaidty inner join pthproto.pthdbo.cnaaddr on cnaidta.tfkcnaaddr = cnaaddr.tpkcnaaddr order by cnaidta.dateeffect
select *, case when mailaddress is not null then mailaddress else formataddr end as test from #address where tpkcnarole = '18306695'
The case when statement is struggling with how i have created the column mailaddress. As it does seem to understand when it is null. In the example I have got there is no value in any of the columns to create
the mailaddress. Hence why I am referencing it from elsewhere. Due to having a way on the system where it picks up data from 2 different places. The mailaddress is always correct if there is one, hence why
trying to reference that one first. So how do i change this case when statement to work ?It's ok I have fixed my own problem
when
(mailaddress
is
null
or mailaddress
=
then formataddr
else mailaddress
end
as test

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,
AnnmarieHappy 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
end Regards

SQL - Select Help - Case When? Return Value from Second Table?
Hi - next to folks on this board I am probably somewhere between a Beginner and an Intermediate SQL user.
Ive been using a case when statement in plsql to find "all those who's status in any program was cancelled during a specific time, but have become or are still active in a second program"
So, Im effectively trying to return a value from a second table in a case when, but its not liking anthing other than a declared text like 'Yes' or 'No'.
Here is the select statement - is there another way to do this where I can get the results I need?
case when pp.party_id in (select pp1.party_id -- Cancelled clients Active in another program
from asa.program_participation pp1,
asa.curr_prog_participation_status cpps1
where pp1.program_participation_id = cpps1.program_participation_id
and pp1.party_id = pp.party_id
and cpps1.code_value = 'ACT')
then 'Yes' else 'No' end as Active_in_Other_Prg
So - in place of 'Yes' i basically want the program that they are active in or pp1.program_id, else Null
It is possible that the client can be active in more than one program as well.
Any assistance is greatly appreciated, i explored with if's and decodes but I cant get anything to work.
BateseySounds like an outer join. See ora doc: Joins
select p.*
, q.party_id
, q.program_id
from table_with_party_id p
, ( select pp1.party_id -- Cancelled clients Active in another program
, pp1.program_id
from asa.program_participation pp1,
asa.curr_prog_participation_status cpps1
where pp1.program_participation_id = cpps1.program_participation_id
and pp1.party_id = pp.party_id
and cpps1.code_value = 'ACT') q
where p.party_id = q.party_id ( +)
Note: In the example above there shoudn't be a space between the ( and +), but the forum software automagically converts this to
The outer join will link show all records from the p table and only records from q if the party_id matches, ie q.party_id and q.program_id will be null if there is no match.
edit: added program_id -

Before CASE came along you had to DECODE(SIGN(...)), e.g:
WITH test AS
( SELECT DATE '2007-02-20' AS dt FROM dual UNION ALL
SELECT DATE '2007-02-04' FROM dual UNION ALL
SELECT DATE '2007-02-01' FROM dual UNION ALL
SELECT DATE '2006-12-01' FROM dual UNION ALL
SELECT DATE '2006-01-01' FROM dual )
SELECT dt
, SIGN((SYSDATE -30) - dt)
, DECODE(SIGN((SYSDATE -30) - dt),
-1, 'Y')
FROM test;
DT SIGN((SYSDATE-30)-DT) D
20-FEB-2007 -1 Y
04-FEB-2007 -1 Y
01-FEB-2007 -1 Y
01-DEC-2006 1

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,
select cr.customer_name || ' - ' ||cr.customer_number as cust_name,
cr.salary as salary
from customer_details cr
where ( v_variable = 'bigger'
and cr.salary > 5000
or ( v_variable = 'less'
and cr.salary < 5000
or ( v_variable = 'eq'
and cr.salary = 5000
