Case statement and group by
Hi,
When I try to group by a case statement , i get not "ORA-00979 not a group by emxpression"
select
CASE WHEN I.transaction_cd IN ('PAY0','PAY1') THEN
CASE When I.acct_cd In (Select 3201040 from dual) Then 'SP'
Else 'FYP'
End
END x
FROM Pol_daily I
group by
CASE WHEN I.txttransaction_cd IN ('PAY0','PAY1') THEN
CASE When I.txtacct_cd In (Select 3201040 from dual) Then 'SP'
Else 'FYP'
End
END
Can someone help me please.
But result will be different..

Case Statement and Group By issues
Hi this is my initial query which works perfectly:
select ff.cla_case_no, Cost_before_Decision, Cost_Of_Claim, decline, Decline_Description from
fraud_nov_14_final ff
,(select cla_case_no, (sum(total_cost_adj_old) + sum(decline_estimate)) Cost_before_Decision
from reporting.ci_final@test
group by cla_case_no) z
where ff.cla_case_no = z.cla_case_noI now want to add in a condition based on a column called decline:
select ff.cla_case_no, Cost_before_Decision, Cost_Of_Claim, ff.decline, Decline_Description from
fraud_nov_14_final ff
,(select cla_case_no, (case when decline = 1 or decline = 2 THEN (sum(total_cost_adj_old) + sum(decline_estimate)) ELSE Total_Cost END) Cost_before_Decision
from reporting.ci_final@test
group by cla_case_no) z
where ff.cla_case_no = z.cla_case_noThe error message I receive is :
ORA-00979: not a GROUP BY expression
00979. 00000 - "not a GROUP BY expression"
Thanks in advance for your help!!

TNS for Linux: Version 11.2.0.2.0 - Production
NLSRTL Version 11.2.0.2.0 - ProductionYou would need DECLINE in the group by clause of your inner query.
Additionally you would need to change TOTAL_COST to SUM(TOTAL_COST) in where case statement.
But then you would retrieve one row for each value of DECLINE in this query.
You also could use this:
(I don't know if it will meet your requirements)
SELECT ff.cla_case_no,
cost_before_decision,
cost_of_claim,
ff.decline,
decline_description
FROM fraud_nov_14_final ff,
(SELECT cla_case_no,
SUM (decode(decline,1,total_cost_adj_old+decline_estimate,
2,total_cost_adj_old+decline_estimate,
total_cost)) cost_before_decision
FROM reporting.ci_final@test
GROUP BY cla_case_no) z
WHERE ff.cla_case_no = z.cla_case_no;(untested code, because I don't have your tables)

CASE STATEMENTS AND CASE EXPRESSIONS IN ORACLE9I PL/SQL
제품 : PL/SQL

CASE STATEMENTS AND CASE EXPRESSIONS IN ORACLE9I PL/SQL
=======================================================
PURPOSE
아래의 자료는 Case 문에서 oracle 8.1.7과 Oracle 9i의 New Feature로 8.1.7에서는
sqlplus 에서만 가능했고, 9i 부터는 pl/sql 까지 가능하다.
Explanation
1. Oracle 8.1.7 Feature
Oracle 8.1.7 에서 Case 문은 Decode 문과 유사하지만, 기존의 decode 문을 쓰는 것보다
더 많은 확장성과 Logical Power와 좋은 성능을 제공한다. 주로 나이와 같이 category 별로
나눌때 주로 사용하고 Syntex는 아래와 같다.
CASE WHEN <cond1> THEN <v1> WHEN <cond2> THEN <v2> ... [ELSE <vn+1> ] END
각각의 WHEN...THEN 절의 argument 는 255 까지 가능하고 이 Limit를 해결하려면
Oracle 8i Reference를 참조하면 된다.
The maximum number of arguments in a CASE expression is 255, and each
WHEN ... THEN pair counts as two arguments. To avoid exceeding the limit of 128 choices,
you can nest CASE expressions. That is expr1 can itself be a CASE expression.
Case Example : 한 회사의 모든 종업원의 평균 봉급을 계산하는데 봉급이 $2000보다 작은경우
2000으로 계산을 하는 방법이 pl/sql을 대신하여 case function을 사용할 수 있다.
SELECT AVG(CASE when e.sal > 2000 THEN e.sal ELSE 2000 end) FROM emp e;
Case Example : 나이를 column으로 가지고 있는 customer table을 예로 들어보자.
SQL> SELECT
2 SUM(CASE WHEN age BETWEEN 70 AND 79 THEN 1 ELSE 0 END) as "70-79",
3 SUM(CASE WHEN age BETWEEN 80 AND 89 THEN 1 ELSE 0 END) as "80-89",
4 SUM(CASE WHEN age BETWEEN 90 AND 99 THEN 1 ELSE 0 END) as "90-99",
5 SUM(CASE WHEN age > 99 THEN 1 ELSE 0 END) as "100+"
6 FROM customer;
70-79 80-89 90-99 100+
4 2 3 1
1 SELECT
2 (CASE WHEN age BETWEEN 70 AND 79 THEN '70-79'
3 WHEN age BETWEEN 80 and 89 THEN '80-89'
4 WHEN age BETWEEN 90 and 99 THEN '90-99'
5 WHEN age > 99 THEN '100+' END) as age_group,
6 COUNT(*) as age_count
7 FROM customer
8 GROUP BY
9 (CASE WHEN age BETWEEN 70 AND 79 THEN '70-79'
10 WHEN age BETWEEN 80 and 89 THEN '80-89'
11 WHEN age BETWEEN 90 and 99 THEN '90-99'
12* WHEN age > 99 THEN '100+' END)
SQL> /

100+ 1
70-79 4
80-89 2
90-99 3
Example
2. Oracle 9i Feature
Oracle 9i부터는 pl/sql에서도 case문을 사용할 수 있으면 이것은
복잡한 if-else 구문을 없애고, C언어의 switch문과 같은 기능을 한다.
아래의 9i pl/sql Sample 및 제약 사항을 보면 아래와 같다.
Sample 1:
A simple example demonstrating the proper syntax for a case
statement
using a character variable as the selector. See the section entitled
'Restrictions' at the end of this article for details on which PLSQL
datatypes may appear as a selector in a case statement or
expression.
- - - - - - - - - - - - - - - - Code begins here - - - - - - - - - - - -
set serveroutput on
declare
achar char(1) := '&achar';
begin
case achar
when 'A' then dbms_output.put_line('The description was Excellent');
when 'B' then dbms_output.put_line('The description was Very Good');
when 'C' then dbms_output.put_line('The description was Good');
when 'D' then dbms_output.put_line('The description was Fair');
when 'F' then dbms_output.put_line('The description was Poor');
else dbms_output.put_line('The description was No such Grade');
end case;
end;
- - - - - - - - - - - - - - - - Code ends here - - - - - - - - - - - -
Sample 2:
A simple example demonstrating the proper syntax for a case
expression
using a character variable as the selector. See the section entitled
'Restrictions' at the end of this article for details on which PLSQL
datatypes may appear as a selector in a case statement or
expression.
- - - - - - - - - - - - - - - - Code begins here - - - - - - - - - - - -
set serveroutput on
declare
achar char(1) := '&achar';
description varchar2(20);
begin
description :=
case achar
when 'A' then 'Excellent'
when 'B' then 'Very Good'
when 'C' then 'Good'
when 'D' then 'Fair'
when 'F' then 'Poor'
else 'No such grade'
end;
dbms_output.put_line('The description was ' || description);
end;
- - - - - - - - - - - - - - - - Code ends here - - - - - - - - - - - -
NOTE: The above simple samples demonstrate two subtle differences in the
syntax
required for case statements and expressions.
1) A case STATEMENT is terminated using the 'end case' keywords; a
case
EXPRESSION is terminated using only the 'end' keyword.
2) Each item in a case STATEMENT consists of one or more
statements, each
terminated by a semicolon. Each item in a case expression
consists of
exactly one expression, not terminated by a semicolon.
Sample 3:
Sample 1 demonstrates a simple case statement in which the selector
is
compared for equality with each item in the case statement body.
PL/SQL
also provides a 'searched' case statement as an alternative; rather
than
providing a selector and a list of values, each item in the body of
the
case statement provides its own predicate. This predicate can be any
valid boolean expression, but only one case will be selected.

set serveroutput on
declare
achar char(1) := '&achar';

Excellent');
when achar = 'B' then dbms_output.put_line('The description was Very
Good');
when achar = 'C' then dbms_output.put_line('The description was
Good');
when achar = 'D' then dbms_output.put_line('The description was
Fair');
when achar = 'F' then dbms_output.put_line('The description was
Poor');
else dbms_output.put_line('The description was No such Grade');
end case;
end;
- - - - - - - - - - - - - - - - Code ends here - - - - - - - - - - - -
Sample 4:
This sample demonstrates the proper syntax for a case expression of
the
type discussed in Sample 3 above.
- - - - - - - - - - - - - - - - Code begins here - - - - - - - - - - - -
set serveroutput on

when achar = 'C' then 'Good'

end;
dbms_output.put_line('The description was ' || description);
end;
- - - - - - - - - - - - - - - - Code ends here - - - - - - - - - - - -
Sample 5:
This sample demonstrates the use of nested case statements. It is
also
permissable to nest case expressions within a case statement (though
it
is not demonstrated here), but nesting of case statements within a
case
expression is not possible since statements do not return any value.

set serveroutput on

anum1 number := &anum1;

end case;
dbms_output.put_line('The answer is ' || answer);
end;
- - - - - - - - - - - - - - - - Code ends here - - - - - - - - - - - -
Sample 6:
This sample demonstrates nesting of case expressions within another
case
expression. Note again the absence of semicolons to terminate both
the
nested case expression and the individual cases of those
expressions.

Although PL/SQL anonymous blocks have been used in all of the examples
so far,
case statements and expressions can also be used in procedures,
functions, and
packages with no changes to the syntax.
The following samples are included for completeness and demonstrate the
use of
case statements and/or expressions in each of these scenarios.
Sample 7:
This sample demonstrates use of a case statement in a stored
procedure.
Note that this sample also demonstrates that it is possible for each
of
the items in the case body to consist of more than one statement.

제약 사항
다음의 databasetype은 case 문에서 지원되지 않는다.
BLOB
BFILE
VARRAY
Nested Table
PL/SQL Record
PL/SQL Version 2 tables (index by tables)
Object type (user-defined type)
All of these types except for object types face a similar restriction
even for if statements (i.e. they cannot be compared for equality directly) so this is unlikely to change for these types. Lack of support for object types is simply an implementation restriction which may be relaxed in future releases.

NOTE:131557.1I have done the following code but doesn't
like the statement of - "case(butNext)". What do you mean "doesn't like" -- did you get an error message?
I'm guessing it won't compile because you're trying to switch on a Button.
I tried something
like "g.fillOval(100,50,70,90, BorderLayout.NORTH)"...no that doesn't make sense. You only use BorderLayout.NORTH when you're adding components to a BorderLayout layout manager. An oval is not a component and fillOval isn't adding a component and Graphics is not a Panel or layout manager.
Would appreciate it if someone could tell me how to position
shapes using the graohic method. I think the problem is that you're confusing shapes with components. -

Case statement and Decode function both are not working in Select cursor.
I have tried both the Case statement and Decode function in Select cursor, but both the things are not working. On the other hand both the things work in just select statement.
See the first column in select (PAR_FLAG), I need to have this evaluated along with other fields. Can you please suggest some thing to make this work. And also I would like to
know the reason why decode is not working, I heard some where Case statement do not work with 8i.

Regarding case statement and decode function
Hi Experts,
I have question.....regarding case statement and decode statement....
Can you please explain me that which one will be efficient,to place in insert statement...
insert statement(
(case when ........then
case when ....then
else
end)
else
end)
or
insert statement(
case when.....then
decode(....)
else
end)
Can you people explain me which one is more efficient method?
Thanks in advance.......The are major differences to talk about in case of CASE vs DECODE, but performance wise both are pretty much the same.
Have a look at Tom's thread
Ask Tom &quot;better performance - case or decode&quot;
I would suggest to use CASE whenever possible. Don't worry about the performance part. -
Difference beween Case Statement and Pivot Operator in a OWB mapping
Hi ,
Kindly clarify what is the difference between using a PIVOT operator and the CASE statement in a Expression Operator in a particular mapping.
rgds
ArinjitHi
With PIVOT operator you can transform columns to rows. For example if oyu have 12 column (one for every months) than you can create 12 rows with one column of month data.
If you want to do this without PIVOT you can do it with union (12 times) or with
something like this.
In this case you can't use CASE statement I think.
If you want to do the reverse of this, create 12 column from 12 rows, you can use UNPIVOT operator. In this case you can use CASE statement and aggregating.

Problem w/ Case Statement and Video Capture
Hey!
I've got a question about a topic which seems pretty trivial, but has been giving me quite the trouble for some time now. I was hoping that someone on this forum would be able to help me catch and fix my mistake.
Basically what I'm trying to do is capture video from a camera, run some video analysis for a certain duration, and store the raw footage for that same duration in an avi file. I'm using IMAQdx and a Logitech C920 camera to gather video. When I run the program, I want there to be an output of the raw video on the front panel. When I then hit a button, I would like the camera to save a .avi file of the video for a set number of frames and concurrently run some analysis and display the results on another display on the front panel. The purpose of the raw footage in the .avi file is to be able to run the analysis again at a later date.
I've attached both a screenshot and the .vi file to this post. When I run the current script, I'm confronted with one of two possible errors (not sure why they're different from time to time). The Video Acquisition Block either "Time Out"s or the Write to AVI block issues an incompatible image type error. The reason why I'm baffled by this is because when I take it out of the case statement and have it run with the rest of the program, the .avi file is generated accurately and stored.
Any help would be greatly appreciated. Thanks!

11_30_12 TrackVIEW.vi 271 KBGreetings,
Would the time out error happen every time you run the VI? In addition, do these errors have a code?
I was able to replicate the issue and initially believe that it might be that we are simultaneously opening two sessions to the same camera. Could you simply take a finite number of images from the first acquisition and chain the second one via sequence structure? It would limit the viewer to only view the video on the other Image Display during saving the AVI, but it might be worthwhile looking into.
It might also be worthwhile to consider enquewing a certain number of images whenever the button is pressed, but that would require some more programming logic.
Cordially;

CASE Statement - and checking number ranges
I am attempting to write a bit of SQL that can be used to do a count of Requisition Values, in different value bands, e.g.:
0 - 250
251 - 500
501 - 1000
etc...
I have got this far:
SELECT sum_value
, COUNT(req_id) req_ct
FROM (SELECT prha.requisition_header_id req_id
, CASE SUM(prla.unit_price * prla.quantity)
WHEN 250
THEN '250'
WHEN 500
THEN '500'
WHEN 500
THEN '1000'
ELSE 'OTHER'
END sum_value
FROM po.po_requisition_headers_all prha
, po.po_requisition_lines_all prla
WHERE prha.requisition_header_id = prla.requisition_header_id
AND prha.creation_date >= SYSDATE - 3
GROUP BY prha.requisition_header_id
, prla.requisition_header_id) rt
GROUP BY sum_value;
SUM_V REQ_CT
250 3
500 6
OTHER 726But - it is not that great, in that it counts REQs with an exact value of 250,400,500 etc.
I am trying to work out the syntax to allow the CASE statement to work with ranges, but I can't work it out.
I have naively attempted this, for example:
WHEN > 250 AND 500
But that errors out, because I can see that the '>' needs to know what it is checking
Any help much appreciated.
Thank youThanks for the reply Sarma,
I've attempted that:
SELECT sum_value
, COUNT(req_id) req_ct
FROM (SELECT prha.requisition_header_id req_id
, CASE SUM(prla.unit_price * prla.quantity)
WHEN BETWEEN 250 AND 500
THEN '250 - 500'
WHEN BETWEEN 501 AND 1000
THEN '501 - 1000'
WHEN BETWEEN 1001 AND 2500
THEN '1001 - 2500'
ELSE 'OTHER'
END sum_value
FROM po.po_requisition_headers_all prha
, po.po_requisition_lines_all prla
WHERE prha.requisition_header_id = prla.requisition_header_id
AND prha.creation_date >= SYSDATE - 3
GROUP BY prha.requisition_header_id
, prla.requisition_header_id) rt
GROUP BY sum_value;But I can see that it doesn't work because I need to state what 'blah' is!
For example, if I tried to state 'blah' as follows:
SELECT sum_value
, COUNT(req_id) req_ct
FROM (SELECT prha.requisition_header_id req_id
, CASE SUM(prla.unit_price * prla.quantity)
WHEN SUM(prla.unit_price * prla.quantity) BETWEEN 250 AND 500
THEN '250 - 500'
WHEN SUM(prla.unit_price * prla.quantity) BETWEEN 501 AND 1000
THEN '501 - 1000'
WHEN SUM(prla.unit_price * prla.quantity) BETWEEN 1001 AND 2500
THEN '1001 - 2500'
ELSE 'OTHER'
END sum_value
FROM po.po_requisition_headers_all prha
, po.po_requisition_lines_all prla
WHERE prha.requisition_header_id = prla.requisition_header_id
AND prha.creation_date >= SYSDATE - 3
GROUP BY prha.requisition_header_id
, prla.requisition_header_id) rt
GROUP BY sum_value;It still errors. I guess I am doing something fundamentally wrong, but I can't see how I can refer to the 'sum' value, to then use it in the Between section of the Case statement.

How to manipulate arrays using case statements and boolean conditions?
In the vi that is attached I am trying to compare two values in two different arrays and delete the value that is equal to zero. The values of each array are rounded to the closest integer. Then I attempted to apply the ">0" boolean as the condition for my case statement, but I am getting an error. Any tips on manipulating arrays with case statements?
Attachments:
Patient Movement Monitoring.vi 141 KBThank you!!! that was a huge help. I don't think I need the case structures at all. The next part of the code compares the 4 values in the array.
If columns 0 and 1 are both positive -> output 1
If column 0 is negative and 1 is positive -> output 2
If columns 0 and 1 are both negative -> output 3
If column 0 is positive and 1 is negative -> output 4
(0 is x-axis value, 1 is y-axis value.....outputs are assigning quadrants to the combination)
Only one of the "AND" booleans will return true for each index. Is there a way to initialize another array of outputs 1-4 depending on which AND returns true?

Case Statement and Sequential Count
I would like to obtain user input via a prompt and use what the user selects in my OBIEE Report case statement. I ve done the parameter part with a presentation variable.
and a filter with the following.
Recv Date is between @{Repair_Start_Date}{01-01-2013} and @{Repair_End_Date}{01-01-2013}
Now I would like to have a sequential count of the records that meet the case statement, please advise.
For example &START_DATE AND &END_DATE are user inputs:
CASE when SHIP_DATE BETWEEN &START_DATE AND &END_DATE THEN 1
ThanksHi,
Here is a way you could try.
CASE when SHIP_DATE BETWEEN &START_DATE AND &END_DATE THEN RSUM(1) END
So, what it does?
Whenever the CASE statement is satisfied, it increments 1 by 1.
Hope this helps.
Thank you,

Basically what I am trying to do is create three Ovals (only mangaged to one but would appreciate some help if someone can tell me how to position ovals on a screen :=D) which when a single command is pressed the specified oval changes color, i.e. a traffic light system. I have done the following code but doesn't like the statement of - "case(butNext)". Can someone point me in the right direction :=). I tried something like "g.fillOval(100,50,70,90, BorderLayout.NORTH)"... well something like that but was no good. Would appreciate it if someone could tell me how to position shapes using the graohic method. I know how to do it with command buttons, list boxes etc but its not the same with shapes :=(.
import java.awt.*;
import java.applet.*;
public class traffic extends Applet {
Button butNext;
Color red = Color.red;
Color orange = Color.orange;
Color green = Color.green;
public void init() {
butNext = new Button("Red");
add(butNext);
public void paint(Graphics g) {
switch(butNext)
case 0:
g.setColor(red);
g.fillOval(100,50,70,80);
break;
case 1:
g.setColor(orange);
g.fillOval(100,50,70,80);
break;
case 2:
g.setColor(green);
g.fillOval(100,50,70,80);
break;
}Appreciate any responses. Thank You :=DI have done the following code but doesn't
like the statement of - "case(butNext)". What do you mean "doesn't like" -- did you get an error message?
I'm guessing it won't compile because you're trying to switch on a Button.
I tried something
like "g.fillOval(100,50,70,90, BorderLayout.NORTH)"...no that doesn't make sense. You only use BorderLayout.NORTH when you're adding components to a BorderLayout layout manager. An oval is not a component and fillOval isn't adding a component and Graphics is not a Panel or layout manager.
Would appreciate it if someone could tell me how to position
shapes using the graohic method. I think the problem is that you're confusing shapes with components. -
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
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

Controlling program flow and case statements
Hey all, I was wondering, I if I have 40 nested case statements and I want the program to close after they are all done, is it sufficient to wire the "?" for both true and false of the outermost case to the close routine in order to guarantee that all of them will execute? Or is there an even better way using data flow methods?
-DobbsI'd recommend state machines better than that way or sequences, to controll dataflow better. Example is attached.
