Hi,
Sure; a DECODE or CASE expression that returns a NUMBER can be used any place a NUMBER is expected, including within another DECODE or CASE expression. A DECODE or CASE expression that returns a DATE can be used any place a DATE is expected, including within another DECODE or CASE expression. A DECODE or CASE expression that returns a VARCHAR2 can be used almost any place a VARCHAR2 is expected. (There a couple of special situations where a string literal is absolutely required.)
There are not many situations where you really need to do that, though. It's usually simpler and more efficient to use a single CASE expression; nesting is rarely needed.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Simplify the problem as much as possible, so that it contains only enough to show the part you don't already know how to do.
If you really need a user-defined function to show the problem, then include a CREATE FUNCTION statement, and explain what the function does. Again, simplify: if the function isn't what you don't understand, post a problem that doesn't use the function.
Always say what version of Oracle you're using (e.g. 11.2.0.2.0).

Help with Decode/CASE function
Can anyone provide some help or insight how can this be done.
Senario:
I have two parameters in my report.
Paramerer_A and Parameter_B
If I enter a value (XYZ) in Parameter_A and value (XYZ) in Parameter_B, I want the report to display ERROR and do not run.Hi
It is not possible to have a use defined message come up based on the values of parameters but we can stop the workbook from executing.
First of all, you will will need to make sure that both parameters are optional and then create your condition such that it will not run if both are populated, like this:
(Item1 = :Parameter_A OR Item2 = :Parameter_B)
AND NOT
:Parameter_A IS NOT NULL AND :Parameter_B IS NOT NULL
You can also put in a check parameter that controls whether A or B should be used, with a prompt like this: Use Parameter A or Parameter B? Enter A or B
:Check_Parameter = 'A' AND Item1 = :Parameter_A
OR
:Check_Parameter = 'B' AND Item2 = :Parameter_B

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...

I'm stuck on my coding when I have to write a function to
detect upper cases has been used in a sentence
For example if my array element has this:
2345
SAINT PAUL
STREET
APT 5
PHILADELPHIA
I need to be able to write a code to let me know that the 2nd
OR 3rd OR 5th element is written in upper case letter
Or if I set the variable not as array, 2345 SAINT PAUL STREET
APT 5 PHILADELPHIA
I need to be able to detect that at least one of the section
on that street name is written with upper case
Can anyone help please?compare() cf function performs a case-sensitive comparison of
2 strings
and returns 0 is the strings are the same. so you can compare
an
uppercase version of the string to the original string, and
if the
comparison returns 0 then your string is in uppercase:
<cfif compare(ucase(myarray[2]), myarray[2]) is 0>
<!--- the string in myarray[2] IS in uppercase --->
<cfelse>
<!--- it is NOT in uppercase --->
</cfif>
the above code compares the value of the second array element
converted
to uppercase to the original value of the second array
element. if the
result is 0, i.e. the uppercase and original strings are the
same, then
you know the original string is in uppercase.
if you are dealing with a single string (which is equivalent
to a
space-delimited list), then use appropriate list function to
get
required list element, i.e. listfirst(), listlast(),
listgetat()...
<cfif compare(ucase(listlast(mylist, " ")),
listlast(mylist, " ")) is 0>
<!--- the last element in the list IS in uppercase --->
<cfelse>
<!--- it is NOT in uppercase --->
</cfif>

Help with multiple case statements
Hello,
I am new to BO. I am on XI 3.0. SQL 2005. In Designer, I am trying to create a measure in a financial universe that would end up being multiple case statements within one select. This is what I tried to do, but it doesn't work with the two case statements. Can I use an ELSE leading into the second CASE WHEN somehow? How can I accomplish this? Sorry for my ignorance!
CASE WHEN dbo.ClientBudgetYear.DateStage1Approved > 01/01/1900 AND dbo.ClientBudgetMonth.Month = 12 THEN dbo.ClientBudgetMonth.Stage1Sales END
CASE WHEN dbo.ClientBudgetYear.DateStage1Approved > 01/01/1900 AND dbo.ClientBudgetMonth.Month = 11 THEN dbo.ClientBudgetMonth.Stage1Sales END
Any Suggestions?
Thanks,
HollyHolly,
I don't know enough about your data or requirement to provide a solution, however, the construct that you post will not work because it causes you to build an object with multiple case statements when only one case statement per object is permitted. From what I see in your code I would be inclined to combine the two statements into one as such:
CASE WHEN dbo.ClientBudgetYear.DateStage1Approved > 01/01/1900 AND dbo.ClientBudgetMonth.Month in (11,12) THEN dbo.ClientBudgetMonth.Stage1Sales else null END
Thanks,

Help with decode or case statement
I have the following insert statement
insert into t_outcome (
TRANSACTION_ID,
charge_DATE,
Charge_TIME,
STATUS_CODE)
values(cur_tem.transaction_id,
cur_tem.charge_date,
cur_tem.charge_time,
cur_tem.STATUS_code)
I require to incorporate the following rules into the population of charge_TIME
if cur_tem.STATUS_code is 7 and cur_temp.charge_time is not null then populate charge_TIME with cur_temp.charge_time
else if cur_tem.STATUS_code is 7 and cur_temp.charge_time is null then populate charge_TIME with -9
else if cur_tem.STATUS_code is not 7 then populate charge_TIME with -7
How do I add these rules into the insert statement ?
Thanks
Brendondecode(cur_tem.STATUS_code, 7, nvl(cur_tem.charge_time, -9), -7)
I think that will work.

Hello!!
Can anyone please help me with the decode statement
Table 1 Table2 Table3
Id Id Code
Volume Code
For each of the codes in Table3 I need to find the corresponding Volume. Can I use decode in the select statement to this,
Eg Code Volume
ABC 20
XYZ 10 etc etc.
Thankyou all in advance.Your table structure is a little unclear from your post. I am assuming that what you posted was:
Table 1
Id
Table2
Id
Code
Table3
Volume
Code You can use decode if there are only a few values for table3. For example,
SELECT table2.code,
DECODE(table2.code,'ABC',10,'XYZ',20,'UNKNOWN') volume
FROM table2
or even
SELECT code,DECODE(code,null,'NONE',
(SELECT volume FROM table3 where code=table2.code)) volume
FROM table2However, the first will break, or at least be incorrect, if anyone adds a new code/volume pair, and is tedious if you have more than a few values. The second will likely be pretty slow if there are a large number of records in table3. The best solution would be to use a simple join rather than decode. Something like:
SELECT table1.id, table2.code, table3.volume
FROM table1, table2, table3
WHERE table1.id = table2.id and
table2.code = table3.code -
Let's call the field "xfieldx". It’s currently a char data type that either gets inputted as null or “y” meaning yes. The problem comes when the query counts the number of rows that have a non-null value. The sql is below
sum(decode(xfieldx, null, 0, 'n', 0, 1)) as xfieldxCount
still returns a char value and later, when subject to a numeric condition “>” it fails. I need to make sure that this count is occurring correctly. Any wisdom?Welcome to the forum!
Whenever you have a question, please post a little sample data (CREATE TABLE and INSERT statements), and the results you have from that data, so that the people who want to help you can re-create the problem and test their ideas.
If you have an existing query, post the complete query, point out where it's getting the wrong results, and explain how you'd get the right results in those places.
Always say which version of Oracle you're uisng.
Since this is your first post, I'll do some sample data for you:
CREATE TABLE table_x
( x_id NUMBER (4) PRIMARY KEY
, xfieldx VARCHAR2 (1)
INSERT INTO table_x (x_id, xfieldx) VALUES (0, NULL);
INSERT INTO table_x (x_id, xfieldx) VALUES (1, 'n');
INSERT INTO table_x (x_id, xfieldx) VALUES (2, 'y');
INSERT INTO table_x (x_id, xfieldx) VALUES (3, 'n');

Any wisdom?That DECODE doesn't return a CHAR; it returs a NUMBER, either 0 or 1. (You can't use SUM on a CHAR expression.) And it's guaranteed either 0 or 1, never NULL. If you're interested in how many of the rows have a non-NULL value, just use COUNT.
The following query shows the difference:
SELECT SUM ( DECODE ( xfieldx
, NULL , 0
, 'n' , 0
, 1
) AS total_y
, COUNT (xfieldx) AS count_xfieldx
FROM table_x
;Output:
` TOTAL_Y COUNT_XFIELDX
1 3This should work in any version of Oracle.

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. -

Hi,
I need to write a DECODE function to which if I pass 'mystring' and if it has the value 'M' it should output 'M', if it has a value of 'F' it should output 'F' and if mystring is not same as string_coded then it should output string_coded.
I know the below statement is incorrect.
decode (mystring, 'M', 'M', 'F', 'F', (mystring <> string_coded), string_coded)
Is there a way to correct this DECODE? Please suggest.
Thanks.It is not clear of you want it to match the string 'string_coded' or if it is some column name, but with the example below you should be able to figure out what to adjust to make it work in your case.
SQL> create table mytable

3 select 'M' mystring, 'X' string_coded from dual union all
4 select 'F', 'X' from dual union all
5 select 'X', 'X' from dual union all

I read the tut on switch statements. My assignment is asking me to do something that is not detailed in that explanation ;
I have a total of 5 case statements, 1-4 and a default statement. The instructions for them are as follows:
Case 1: If the user enters a 1, display a message that informs users they are correct, as any input canbe saved as a String. Enter the break statement.
Case 2: If the user enters a 2, parse the value into tryInt. Display as message that informs the users they are correct. Enter the break statement.
Case 3. If they user enters a 3, parse the value into tryDouble. Display a message tha t informs users they are correct. Enter the break statement.
Case 4: Set done equal to true. Enter code to display a closing message. Enter a break statement.
Case default: throw a new NumberFormatException.;
Here is the code
import java.io.*;
import javax.swing.JOptionPane.*;
public class MyType1
public static void main(String[] args)
//declaring variables
String strChoice, strTryString, strTryInt, strTryDouble;
int choice, tryInt;
double tryDouble;
boolean done = false;
//loop while not done
while (!done)
try
choice = Integer.parseInt(strChoice);
switch(choice)
case 1:
JOptionPane.showMessageDialog(null,"You are correct!");
break;
case 2:
choice = Integer.parseInt(tryInt); JOptionPane.showMessageDialog(null,"You are correct!");
break;
case 3:
choice = Double.parseDouble(tryDouble);
JOptionPane.showMessageDialog(null,"You are correct!");
break;
case 4:
done = true; JOptionPane.showMessageDialog(null,"Goodbye!");
break;
As usual Im doing something wrong. Please help.Thanks for your input. The directions for the assignment tells me to first declare the variables.
Begin a while(!done) loop to repeat as long as teh user does not click the Cancel button.
Inside a try statement, enter code to display an input box with three choices.
Type choice = Integer.parseInt(strChoice); on the next line to parse the value for the choice entered by the user.
(HERE THE SWITCH STATEMENT WITH CAST STATEMENTS)
Close the switch statement with brackets
Create a catch statement.
import java.io.*;
import javax.swing.JOptionPane.*;
public class MyType1
public static void main(String[] args)
//declaring variables
String strChoice, strTryString, strTryInt, strTryDouble;
int choice, tryInt;
double tryDouble;
boolean done = false;
//loop while not done
while (!done)
try
String message = "What is My Type:" + "\n\n1) String\n2)Integer\n3)double\n4)Quit the program\n\n";
choice = Integer.parseInt(strChoice);
//test for valid choice 1, 2, 3, or 4
if (choice<1 || choice>4) throw new NumberFormatException();
else done = true;
switch(choice)
case 1:
JOptionPane.showMessageDialog(null,"You are correct!");
break;
case 2:
choice = Integer.parseInt(tryInt); JOptionPane.showMessageDialog(null,"You are correct!");
break;
case 3:
choice = Double.parseDouble(tryDouble);

break;
case 4:
done = true; JOptionPane.showMessageDialog(null,"Goodbye!");
break;
catch (NumberFormat Exception e)
JOptionPane.showMessageDialog(null, "Please enter a 1, 2, 3 or 4:", "Error", JOptionPane.INFORMATION_MESSAGE);
}Typing this now, I see I dont have anything in my try statement entering code to display an input box with three choices.
(PS. I know I would write a catch statement for the NumberFormatException, but why would I also write this exception in the case statement also??) -
I need to find someone to help with a case # from a previous chat
On 11/17 I chatted online with a gentleman for quite a while discussing a printhead issue. He gave me a case # and sent me new ink to try. That did not work and I have been trying to contact someone to resume the conversation. I was to;ld the printer would then have to be replaced. It is still under warranty. Now I cannot find any help online.
I will ask to have an HP support agent contact you via private message. Do not post any private information (including contact information, case ID's or serial numbers) in the forum here, but you can supply this to the agent in private message if requested.

Help with Switch-Case Statement
How do you get this in a switch-case statement or work with it?
if (age < 70) {
JOptionPane.showMessageDialog(null, "People that are below the 70s are nothing special.");
else if (age > 69 && age < 80) {
JOptionPane.showMessageDialog(null, "People that are in their 70s are called septuagenarian.");
else if (age > 79 && age < 90) {

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..... -
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.

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.
