Help with case statement

Can any one whats wrong in below sql....Error is missing expression ...?
SELECT CASE WHEN A.STG_RECEIVER_MODEL_COUNT = 0 THEN 'STAGING RECEIVER MODEL CAPABILITY CONSISTS OF 0 RECORDS'
WHEN A.STG_RECEIVER_MODEL_CAP > 0 THEN
CASE WHEN ( B.ERROR_COUNT_FOR_4 = 90 * ( A.STG_RECEIEVER_MODEL_CAP_COUNT / 100) ) THEN 'MORE WARNING ERRORS FOR STG_PACKAGE'
ELSE 'WARNING ERRORS ARE LESS THAN 90 PERCENT'
END CASE
END AS WARNING_COUNT
FROM
SELECT COUNT(*) AS STG_RECEIVER_MODEL_COUNT FROM STG_RECEIVER_MODEL_CAPABILITY
) A,
SELECT count(*)AS ERROR_COUNT_FOR_4 FROM STG_ERROR_DETAIL
WHERE ERROR_CAT_ID = 4
AND MAP_NAME = 'STG_RECEIVER_MODEL_CAPABILITY'
AND CREATE_DT = (SELECT CREATE_DATE FROM QA_CREATE_DATE)
) B
;

If you rewrite properly yourquery, it could be easier to find out the error : 
SELECT CASE WHEN A.STG_RECEIVER_MODEL_COUNT = 0
 THEN 'STAGING RECEIVER MODEL CAPABILITY CONSISTS OF 0 RECORDS'
 WHEN A.STG_RECEIVER_MODEL_CAP > 0
 THEN CASE WHEN ( B.ERROR_COUNT_FOR_4 = 90 * ( A.STG_RECEIEVER_MODEL_CAP_COUNT / 100) )
 THEN 'MORE WARNING ERRORS FOR STG_PACKAGE'
 ELSE 'WARNING ERRORS ARE LESS THAN 90 PERCENT'
 END <s>CASE</s>
 END AS WARNING_COUNT
FROM (SELECT COUNT(*) AS STG_RECEIVER_MODEL_COUNT FROM STG_RECEIVER_MODEL_CAPABILITY) A,
 (SELECT count(*)AS ERROR_COUNT_FOR_4
 FROM STG_ERROR_DETAIL
 WHERE ERROR_CAT_ID = 4
 AND MAP_NAME = 'STG_RECEIVER_MODEL_CAPABILITY'
 AND CREATE_DT = (SELECT CREATE_DATE FROM QA_CREATE_DATE)) B

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,
Sumanth

11g outer join with case statement - strange results.

Hello All,
I am experiencing a strange issues in 11g while using case statement.
I am not able to reproduce this using sample data. Not sure what is wrong.
I am not narrowing it to say the usage of case statemnt is giving wrong results, but that is my observation when I am doing trail and error testing.
Here are the details.
My Version
SQL> select * from v$version;

 OR mf.feetype IS NULL)
 AND mf.rbrvsvalue IS NOT NULL
 AND mf.multiplier IS NOT NULL THEN

WHERE inline_fee.schedule = inline_data.col1(+)
 AND inline_fee.cptcode = inline_data.col2(+)
 AND inline_fee.modifier2 = inline_data.col3(+);
In the above query the inline view inline_data returns zero rows. but NVL is still getting applied for col3 and I am getting 00 in the results( strange ).

when I set the parameter "_complex_view_merging"=false I am getting the right results even with case statement. But I don want to do some thing unsupported.
Are there any other viable solutions?
I appreciate the help.

Hi Tubby,
Right, the query transformation is going wrong. Following is from trace,

Using Presentation variables..along with case statements..

Hi All.
I have a issue using presentation variable along with CASE statements. My approach is
1) I have a dashboard prompt, which is being set as Presentation variable.
Based on the value selected in prompt, for ex the values of prompt can be 'ABC' and 'DEF'.
I have a calculated column, the calculation goes this way...
The forumal is
CASE WHEN @{Presentation Variable Name} = 'ABC' THEN xxxxxxxxxx ELSE IF @{Presentation Variable Name} = 'DEF' END. It gives error of "no table being referenced"..
Is this is the right approach??
Can i get the values of variable in a column formula, so that a column can have values selected in prompt?
Can anybody pls help me here..
Thanks in advance...

Hi
Thanks for the quick response..
I agree to ur point..
But the requirement is
Based on the value of the prompt I need to switch the calculation in one of the formula area of one column..
If Prompt value is ABC then one kind of calculation in Fx and If the prompt value is DEF then one kind of calculation in the same Fx..
How can I acheive this?
Thanks in advance..

Help with if statement in cursor and for loop to get output

I have the following cursor and and want to use if else statement to get the output. The cursor is working fine. What i need help with is how to use and if else statement to only get the folderrsn that have not been updated in the last 30 days. If you look at the talbe below my select statement is showing folderrs 291631 was updated only 4 days ago and folderrsn 322160 was also updated 4 days ago.
I do not want these two to appear in my result set. So i need to use if else so that my result only shows all folderrsn that havenot been updated in the last 30 days.
Here is my cursor:
/*Cursor for Email procedure. It is working Shows userid and the string
You need to update these folders*/
DECLARE
a_user varchar2(200) := null;
v_assigneduser varchar2(20);
v_folderrsn varchar2(200);
v_emailaddress varchar2(60);
v_subject varchar2(200);
Cursor c IS
SELECT assigneduser, vu.emailaddress, f.folderrsn, trunc(f.indate) AS "IN DATE",
MAX (trunc(fpa.attemptdate)) AS "LAST UPDATE",
trunc(sysdate) - MAX (trunc(fpa.attemptdate)) AS "DAYS PAST"
--MAX (TRUNC (fpa.attemptdate)) - TRUNC (f.indate) AS "NUMBER OF DAYS"
FROM folder f, folderprocess fp, validuser vu, folderprocessattempt fpa
WHERE f.foldertype = 'HJ'
AND f.statuscode NOT IN (20, 40)
AND f.folderrsn = fp.folderrsn
AND fp.processrsn = fpa.processrsn
AND vu.userid = fp.assigneduser
AND vu.statuscode = 1
GROUP BY assigneduser, vu.emailaddress, f.folderrsn, f.indate
ORDER BY fp.assigneduser;
BEGIN
FOR c1 IN c LOOP
IF (c1.assigneduser = v_assigneduser) THEN
dbms_output.put_line(' ' || c1.folderrsn);
else
dbms_output.put(c1.assigneduser ||': ' || 'Overdue Folders:You need to update these folders: Folderrsn: '||c1.folderrsn);
END IF;
a_user := c1.assigneduser;
v_assigneduser := c1.assigneduser;
v_folderrsn := c1.folderrsn;
v_emailaddress := c1.emailaddress;
v_subject := 'Subject: Project for';
END LOOP;
END;
The reason I have included the folowing table is that I want you to see the output from the select statement. that way you can help me do the if statement in the above cursor so that the result will look like this:
emailaddress
Subject: 'Project for ' || V_email || 'not updated in the last 30 days'
v_folderrsn
v_folderrsn
etc
[email protected]......
Subject: 'Project for: ' Jim...'not updated in the last 30 days'

This table is to shwo you the select statement output. I want to eliminnate the two days that that are less than 30 days since the last update in the last column.

SQL query help with CASE

Hi All,
I have 2 tables like below. now i have a requirement which i need to do it in CASE OR DECODE. because i have to implement this logic IN SELECT STATEMENT for a column.
In table T1 if Lang = 1 and State = 'P' then display Lang = 'english' in table T2(which is Lang=2 in table T1) Or else display null.
Can we do this logic using CASE or DECODE? pls help
T1
Lang State

Help with Switch statements using Enums?

Hello, i need help with writing switch statements involving enums. Researched a lot but still cant find desired answer so going to ask here. Ok i'll cut story short.
Im writing a calculator program. The main problem is writing code for controlling the engine of calculator which sequences of sum actions.
I have enum class on itself. Atm i think thats ok. I have another class - the engine which does the work.
I planned to have a switch statement which takes in parameter of a string n. This string n is received from the user interface when users press a button say; "1 + 2 = " which each time n should be "1", "+", "2" and "=" respectively.
My algorithm would be as follows checking if its a operator(+) a case carry out adding etc.. each case producing its own task. ( I know i can do it with many simple if..else but that is bad programming technique hence im not going down that route) So here the problem arises - i cant get the switch to successfully complete its task... How about look at my code to understand it better.
I have posted below all the relevant code i got so far, not including the swing codes because they are not needed here...
ValidOperators v;
public Calculator_Engine(ValidOperators v){
 stack = new Stack(20);
 //The creation of the stack...
 this.v = v;
public void main_Engine(String n){
 ValidOperators v = ValidOperators.numbers;
 *vo = vo.valueOf(n);*
 switch(v){
 case Add: add(); break;
 case Sub: sub(); break;
 case Mul: Mul(); break;
 case Div: Div(); break;
 case Eq:sum = stack.sPop(); System.out.println("Sum= " + sum);
 default: double number = Integer.parseInt(n);
 numberPressed(number);
 break;
 //default meaning its number so pass it to a method to do a job
public enum ValidOperators {
 Add("+"), Sub("-"), Mul("X"), Div("/"),
 Eq("="), Numbers("?"); }
 Notes*
It gives out error: "No enum const class ValidOperators.+" when i press button +.
It has nothing to do with listeners as it highlighted the error is coming from the line:switch(v){
I think i know where the problem is.. the line "vo = vo.valueOf(n);"
This line gets the string and store the enum as that value instead of Add, Sub etc... So how would i solve the problem?
But.. I dont know how to fix it. ANy help would be good
Need more info please ask!
Thanks in advance.

Insert data with Case Statement

Good Morning,
I created table:
CREATE TABLE DWG_LOG

 DL_NOTES VARCHAR2(100 BYTE),
 DL_REQ_EMAIL VARCHAR2(60 BYTE),
 DL_DATE_DUE DATE,
 DL_PAST_DUE VARCHAR2(400 BYTE))
The goal is to populate the DL_PAST_DUE field with a 1 if the date is greater than 90 days else leave NULL. With the help of other more senior developers from OTN I have narrowed my logic to using a CASE Statement instead of a FUNCTION. Below is the projected CASE statement that I am trying to use:
DECLARE
v_copied_date DWG_LOG.DL_DATE_COPIED%TYPE;
v_curr_date SYSDATE;
BEGIN
SELECT DL_DATE_COPIED INTO v_copied_date
FROM DWG_LOG
CASE
WHEN (v_curr_date - v_copied_date) > 90 THEN
INSERT INTO DWG_LOG (DL_PAST_DUE) VALUES ('1');
ELSE
INSERT INTO DWG_LOG (DL_PAST_DUE) VALUES ('0');
END CASE;
END;
I am getting the following errors when I run this code in SQL*PLus:

i need to display those two values also in %
it may be happen denominater(yagox value is 1)
could please give the proper case statement for resolving the issue

Dear betham,
welcome to the forum, could you please share the table structure and some sample data and also what your select statement is. This will help people come up with solution faster and also it would avoid going in loops.

Help with If statement please

Hi,
First Special thanks to Kglad for the help with the AS1 to AS3 conversion.
I've been able to link up my buttons to play a different frames of the movie. this was my novice way of finally getting the programming to work.
In frame 95 I have
var myLoader:Loader = new Loader();
addChild(myLoader); var url:URLRequest = new URLRequest("page1.swf");
myLoader.load(url);
in frame 165:
var myLoader1:Loader = new Loader();
addChild(myLoader1); var url1:URLRequest = new URLRequest("page1.swf");
myLoader1.load(url1);
My buttons link to 116 which plays a frame and loads ^
in frame 226: removeChild(myLoader).
But if the user has looped back into home from another part in the movie clip then it would need to remove myLoader1 instead of myLoader.
I'm guessing there is some really dynamic way to solve the programatic nightmare i'm developing, but I'm really novice.
So what i need is an if statement for frame 226
That would do something:
if(myLoader <> null
removeChild(myLoader)
else(
removechild(myLoader1)
Anyone have a method for this?

yes, you can use the same urlrequest but just change its url property:
// initialize, for example in frame 1. this is done once and never again:
var loader:Loader=new Loader();
var urlR:URLRequest=new URLRequest();
// then in frame 2, for example:
urlR.url="page1.swf";
loader.load(urlR);
// in frame 20, for example:
urlR.url="page2.swf";
loader.load(urlR);
// in frame 30, for example:
urlR.url="page3.swf";
loader.load(urlR);
//etc. if you're loading any swfs that play streams (sound or video), you'll want to add some code to this.

SQL Expression Field - Combine Declared Variable With Case Statement

Hello All, I have been using Crystal & Business Objects for a few months now and have figured out quite a bit on my own. This is the first real time I have struggled with something and while I could do this as a Formula Field I would like to know how to do this as a SQL Expression. Basically I want to create a SQL Expression that uses a CASE statement but I wanted to make the code a little more efficient and employ a variable to hold a string and then use the variable in the CASE statement. The expression editor accepts the CASE statement OK but I don't know how to declare the variable. Please assist with the syntax?
This is what I have:
CASE
 WHEN u201CDatabaseu201D.u201DFieldu201D = u2018Hu2019 THEN u2018Hedgeu2019
 WHEN u201CDatabaseu201D.u201DFieldu201D = u2018Pu2019 THEN u2018PVIu2019
 ELSE u2018Noneu2019
END
This is what I want:
DECLARE strVar AS VARCHAR(25)
strVar = u201CDatabaseu201D.u201DFieldu201D
CASE
 WHEN strVar = u2018Hu2019 THEN u2018Hedgeu2019
 WHEN strVar = u2018Pu2019 THEN u2018PVIu2019
 ELSE u2018Noneu2019
END

Hi Todd,
Please use the following for loop; your problem will be solved.
Local StringVar str := "";
Local NumberVar strLen := Length ({Database.Field});
Local NumberVar i;
For i := 1 To strLen Do
 if {Database.Field} = "H" then str := "Hedge"
 else if {Database.Field} = "P" then str := "PVI"
 else str := "None"; exit for
str
Let me know once done!
Thank you,
Ashok

Problem with Case statement

Thank you in advancewith Oracle strings are enclosed in single quote marks
so Oracle is confused & unhappy with line below
customer_no =''
since CUSTOMEER_NO is a NUMBER
why do you compare number to a string?

CLOB with case statement not working getting error

Can anyone help on this
I write this sql
select Case when to_clob(PROPERTY) = 'is_intradesk=Y' then 'Internal' end
from JPM_CP;
Where PROPERTY column is clob column and its giving the error "ORA-00932: inconsistent datatypes: expected - got CLOB"
Is it not possible to use clob columns with case or decode !

Its working but it does not fulfill my purpose
In you answer it is looking for position right! means, does the column contain the value('Intradesk=Y' ) or not. means
I am looking for exact match with CLOB column values, that is Clob column(PROPERTY) contains the exact value that value which I am comparing with i.e 'Intradesk=Y'
I need this
select * from table where clob_column = 'value' (exact).

Handling Exceptions with case statement - convert Exception to int value

Hi,
I'm developing a web app, with servlets.
I'm catching Exceptions in my servlets, for example I would like a user to insert data into a form. If the data cannot be converted into a integer value a java.lang.NumberormatException is thrown.
I would like to catch this and then create a message giving a more specific clue to what happened. Unfortunatly it's possible that other exceptions could be caught, so I want to be able to check which type of Exception has been caught.
I started writing a getErrorMessage(int Code) class. The method has a case statement which just checks the code and return the appropriate message.
This worked well for SQL exceptions as they provide a getErrorCode method. But I was wondering is there any way to convert other Exceptions such as
java.lang.NumberormatException into an integer value?
Cheers

Exceptions have their types (classes) and messages (and maybe an embedded exception). That is, they have much richer internal status then an integer.
Why should they be "converted" to integers?

How to use Substring function with Case statement.

Hello Everyone,
I have one requirement where I have to use substring function on the field for report criteria.
E.G.
I have Branch Name Field where I have all branch names information, Now some of the branch names are too big with some extension after the name .
now i want to substing it but the character length varies for each branch.
so is there any way where we can use case statement where we can define that if branch name character are exceeding some value then substing it with this length.

Try something like this:
CASE WHEN LENGTH(tablename.Branch_Name) > n THEN SUBSTRING(...) ELSE tablename.Branch_Name END
where n is the number of characters you want to start the break.
