Nested Case statement

Hello
I need help implementation of multiple Case statements in a select statement. I can not it works in a statement.
SELECT statement

select distinct 
allt.fk_jobcode_id as Job_Code, 
allt.fk_jobcode_descr as Classification,
sum(allt.number_of_positions) as Number_Allotted,
sum(number_of_positions) as Sum_Number_Allotted,
     dept.department_name|| ''||nvl2((CASE WHEN div.division_name <> 'N/A'
    THEN div.division_name  
  END),'/'||DIV.DIVISION_NAME||'',null) as Department_Division,
allt.fund_type as Fund
from tbl_allotment allt, tbl_department dept, tbl_division div
where isdeleted <> 'Y'
 and ALLT.FK_DEPARTMENT_ID = dept.department_id
 and ALLT.FK_DIVISION_ID = div.division_id
group by fk_jobcode_id, fk_jobcode_descr, fund_type, department_name, division_name 
HAVING (count(fk_jobcode_descr ) = 1)
order by Classification asc, Department_Division asc

1st CASE statement combines the Department_Name and Division_Name values, but does not display the Division_Name if the value is "N/a".

     dept.department_name|| ''||nvl2((CASE WHEN div.division_name <> 'N/A'
    THEN div.division_name  
  END),'/'||DIV.DIVISION_NAME||'',null) as Department_Division,

value: administrator Office/Administration Council
value: poster of the administrator of the Office/s/o Board in the Office of the Director of the Board

I need to extend this now using this CASE statement, which displays the text "Public works" If the department_id = 00072.

     (CASE dept.department_id 
     When '00072' then 'Public Works'
     Else dept.Department_Name
     End) as Department_Name,

incorrect: road Rehab program/GLP transport program Admin
Must fill as: work GLP/public transport program Admin

select distinct 
allt.fk_jobcode_id as Job_Code, 
allt.fk_jobcode_descr as Classification,
sum(allt.number_of_positions) as Number_Allotted,
sum(number_of_positions) as Sum_Number_Allotted,
     dept.department_name|| ''||nvl2((CASE WHEN div.division_name <> 'N/A'
    THEN div.division_name  
  END),'/'||DIV.DIVISION_NAME||'',null) as Department_Division,
  (CASE dept.department_id 
     When '00072' then 'Public Works'
    ELSE dept.Department_Name|| ''||nvl2((CASE WHEN div.division_name <> 'N/A'
    THEN div.division_name  
       END),'/'||DIV.DIVISION_NAME||'',null)
  END) as Department_Name1,
allt.fund_type as Fund
from tbl_allotment allt, tbl_department dept, tbl_division div
where isdeleted <> 'Y'
 and ALLT.FK_DEPARTMENT_ID = dept.department_id
 and ALLT.FK_DIVISION_ID = div.division_id
group by fk_jobcode_id, fk_jobcode_descr, fund_type, department_name, division_name, department_id 
HAVING (count(fk_jobcode_descr ) = 1)
order by Classification asc, Department_Division asc

but once I change the select statement I get only value "Public works" for the Department_Division value. Does not meet Division_Name data. Does anyone know how to combine these CASE statements? Thanks for reading this thread also.

Hello

I think you want something like this:

SELECT       ...
,       CASE
           WHEN  department_id = '00072'
           THEN  'Public Works'
           ELSE  dept.department_name
       END
       ||
       CASE
           WHEN  div.division_name != 'N/A'
           THEN  '/' || div.division_name
       END          AS department_name1
...

Whenever you have a problem, post a small example (CREATE TABLE and only relevant columns, INSERT statements) of all database tables.
Also post the results you want from this data, as well as an explanation of how you get these results from these data, with specific examples.
Always tell what version of Oracle you are using.

How can I get the nested case statements to work with listagg?

I have a statement below that does not work as I want it, here is my code:
Select
cases where o.personal_label is not null
then
listagg (cases where s.subcodevalue like '% MON %')
then s.subcodevalue |' '|| o.personal_label
of other s.subcodevalue
end,': ')
the Group (order of s.subcodevalue) as subcodevalue
on the other
listagg (s.subcodevalue,': ')
the Group (order of s.subcodevalue) as subcodevalue
end
of mtm_styles_new s, order_mtm o
where INSTR (o.extras, s.code) > 0
and o.bodyfitting = s.bodyfitting
and o.division = s.division
and s.subcodevalue is not null
and o.ORDER_MTMID = 'somevalue '.
It should bring the following
* MY TEST: RPP
or the following if the first case is not completed:
* MONDAY: RPP
I get an error message saying 'missing keyword', but cannot make out where, can someone please help me here?
The following works fine as long as it is not a nested case statement, but I need to nest the case statement:
Select listagg (cases where s.subcodevalue like '% MON %')
then s.subcodevalue |' '|| o.personal_label
of other s.subcodevalue
end,': ')
the Group (order of s.subcodevalue) as subcodevalue
of mtm_styles_new s, order_mtm o
where INSTR (o.extras, s.code) > 0
and o.bodyfitting = s.bodyfitting
and o.division = s.division
and s.subcodevalue is not null
and o.ORDER_MTMID = 'somevalue ';

Out alias 'subcodevalue as' the case at the end of the case body.

Hi,
You need to add Group by clause at the end of the query i have added above.

Cannot not alias a nested CASE statement?

isn't this possible?
I get an error ora-00905 missing key when I try the CASE expression nested aliasing, but not the outer CASE ("test case").

everything works fine if I leave aside the "BOLD" below:

SOME costs,
CASES where cost > 1100
Then CASE when required in (10.50) then cost/2
cost of other
END "nested box"
what cost > = 1100 and cost < 1500
then cost * 1.1
When the cost is null then 0
cost of other
END "test case".
IN THE course of
WHERE course_no in (80,20,135,450,230)
ORDER BY cost;
Could not see anything in the documentation on this subject, or I forgot

Hello

The columns may have assumed names; expressions that are just a part of computing a column cannot have alias.

If you assign an alias, Oracle does not provide a way to reference it.

If you need to refer to an expression, make a separate column, perhaps in a subquery.

using nested case statement does not get the right result

Hello all;

I have a sample of data similar to below

create table t3
( 
       id varchar2(200),
       qty number(30),
       qty2 number(30)
);

 insert into t3
   (id, qty, qty2)
 values
   ('A', 10, null);
 
  insert into t3
   (id, qty, qty2)
 values
   ('A', 20, null);
   
 insert into t3
   (id, qty, qty2)
 values
   ('B', null, 5);
   
insert into t3
   (id, qty, qty2)
 values
   ('B', null, 5);
   
 insert into t3
   (id, qty, qty2)
 values
   ('C', null, -5);
   
insert into t3
   (id, qty, qty2)
 values
   ('C', null, 5);


 insert into t3
   (id, qty, qty2)
 values
   ('D', -1, -2);
   
insert into t3
   (id, qty, qty2)
 values
   ('D', 1, 4);

This is what looks like data

ID  QTY  QTY2
A    10
A    20
B              5
B              5
C             -5
C              5
D    1        4
D   -1       -2

It is the output that I desired below

ID    Status 
A      Fail
B      Fail
C      Pass
D      Fail

A is a failure because the sum of the 2 has the value zero, where the summation of the qty was used to determine the State and because the sum of the quantity is not equal to zero, then, it is a failure
D is a failure because even if the sum of the Qty 1 equals zero, we must make use of summation of the qty 2 instead because he is not null to determine the status and the summation of the qty is 2, where a failure
etc.

I tried write something but can not make it work

select case when sum(v.qty) is not null
            and sum(v.qty) = 0 then 'Pass'
            when sum(v.qty) is not null
            and sum(v.qty) != 0 then 'Fail'
       else
         case when sum(v.qty2) is not null
           and sum(v.qty2) = 0 then 'Pass'
           else
            when sum(v.qty2) is not null 
              and sum(v.qty2) != 0 then 'Fail'
              end as status
          end as status


 from t3 v;

any help is appreciated. Thank you.

Try this,

SELECT ID,
       CASE WHEN NVL(SUM (qty2),1) !=0 THEN 'fail'
            WHEN NVL(SUM (qty),0) != 0 THEN 'fail'
            ELSE 'pass'
       END
  FROM t3
GROUP BY ID

OUTPUT
-------------

ID RESULT
-- ------
A  fail
B  fail
C  pass
D  fail
Z  fail

Could you please suggest me the correct way on it.
Thank you

You need a group of expression OR the only authorized linked should be aggregation function.

Onw solution could be to put the aggregate function (MAX) education all about box.

Like this

SELECT max)

case

When f.rv = "BITTER" then

case

When (m.SC. = 'A' and str_name = "ST_DT1")

or (m.SC. = 'B' and str_name = "ST_DT2")

or (m.SC. = 'C' and str_name = "ST_DT3")

then m.stdt

Where (mc.sc = 'C' and str_name = "ST_DT4")

or (mc.sc = 'K' and str_name = "ST_DT5")

then mc.eddt

end

end) as maxdate

of memo_con mc

baro_uy b

end f

ped pe

where b.id = mc.id

and pe.id = mc.mid

and pe.id1 = 1234

and b.cd = f.cd

and f.id = 93;

Thank you... I appreciate the information you provide when you answer these questions. I always try to get the amount (from the same column) for 2 rows in different columns. I tried the LAST_VALUE and LAG but it took a long time for the queries to run, I'm looking for another way to do the same. I'm only using SQL to retrieve data. I don't have the ability to create or insert.

I looked the information above and the CASE statement to look like this:

CASE

WHEN RDP. FISCAL_YEAR = 2014

AND pdr. ACCOUNTING_PERIOD = 11

THEN the RDP. ADEATH AS CURR_MONTH

ON THE OTHER

lao PDR. ADEATH AS MONTHS PREVIOUS

END

But I'm now getting an "ORA-00905: lack of keyword" message.

What I'm trying to do is to draw 2 lines 1 to 2014 / 11 and another for 2014 / 10. The amount for the period 2014 / 11 should go in the current column and the amount for the period 2014 / 10 should go in the previous column.

Before current assets management

01 AB01 50.01 50.03

....

If you want to give an alias for a column, then you can say "AS nome_alias" after that tell you what that is in this column.

'AS nome_alias' applies to the entire column. Cannot use 'alias_name' in the middle of an expression, for example, in the middle of a CASE expression, before the END keyword.

If you want to have 2 separate output columns, curr_month and prior_month to your output, you must then 2 separate columns in your SELECT clause. for example:

SELECT pdr.branch

pdr.asset

CASE

WHEN pdr.fiscal_year = 2014

AND pdr.accounting_period = 11

THEN pdr.depr

END AS curr_month

CASE

WHEN...

THEN...

END AS prior_month

If post you some sample data (CREATE TABLE and INSERT statements), the results and explanations, I could show you how to complete the... sections.

To find out what version of Oracle you have, use

Using nested switch/case statements
What is the best practice of two following switch/case statements?

Is there an easier way (less code) to do this?

Thank you.
I think it's as clean as it gets:

call the statement box inside the case statement

I am writing a program which requires me to run a statement box inside another case statement. Although this sounds like a simple thing, I need to be able to call the case statement using a sequence structure, where s1 sends the true value to the case, s2, a fake. Then I need to record the results of this instruction box in a text file. Attatched is a simplified version of what I'm trying to do. Please note that the way my program runs may not call the case statement without using a sequence structure, two nesting box instructions is not feasible. I hope someone out there can help me because I was stuck trying to find this for awhile.

Thank you

Yes you can. You just need to be smart.

I don't think I can use a state machine to fix this.

I think you probably can.

With respect to your original post. What are these s1 and s2 are you talking about? My opinion on the matter, it is that you want to select a case based on the values of several controls Boolean. If this is correct, I do this:

Build your Boolean controls in a table, convert the table number and insert it into the structure of your business. No button pressed = 0, s1 = only 1, s2 = only 2 both = 3. This works for Boolean values as much as you want and is an easy way to make a decision that depends on many entries.

Nested case in the Expression
Hello

I need to create a nested case in an expression statement, but am having no luck. Here's what I need to evaluate:

Case ingroup.field1
When NOT NULL then
Case ingroup.field2
When NULL then 'n/a '.
Of other ingroup.field2
end
of other ingroup.field1
end

When I validate and generate and try to run the SQL outside OWB, I get the following error:
ORA-00936: missing expression.

Any ideas on what I could do wrong here?

Thank you
Paula
Instead of using the ingroup.field1 CASE... .use

CASE WHEN ingroup.field1 IS NOT NULL
THEN
CASE WHEN...

It should work.

CASE statement on the 39gII

I can't get the CASE statement to work on my 39gII. Anyone else out there there is a bit of luck? I keep getting syntax errors.

It does not in the current official version of Setpbember.

Use the control of timing DAQmx as input in case statement

Hello

I'm building a VI aquire sampled under tension of a sensor in continuous mode or finished. I was going to do this, use a box with a cable of the sample mode of the VI DAQmx calendar entry to the terminal State, the idea being that I couldn't aeither a while looping the case for continuous or simple acquisition according to the setting of this command.

However, instead of the sample mode provided for in the case of the case statement, I just get 1 and 0.

It's a good way to achieve this, and if so how can I get my case structure working properly?

Thank you

Dave

Hi Dave,.

Apologies - I consider that the error is from the data acquisition function? I forgot that she was using the sample entry mode.

Perhaps, then, it will be preferable to continue using the control of the ring - cases will be numbered and will correspond to the numeric value of the selection of the ring (i.e. finite samples = 0). I have attached a small example if we know not.

Moreover, the structure of the case cannot automatically fill for each case, in which case you can right click on the structure of the case-> add the case after.

Best regards

Case statement is not spend.

Hello

I'm having a strange problem with a case statement. I'm passing is a Boolean value that is set to false, but the case statement never switches to the loop of "false". I have attached a word doc who did the screen has a step of this unique through being shot. The photo of the top has the case highlighted with the probe #8 beside him indicate 'False. ' In the lower screen shot is the very next step that highlights the outside circle while ' loop', but the case statement is always 'True '. Anyone seen this before?

Gary Tyrna

Hey Mello,

Well, I see what you're saying and you are right, the problem is the case statement works when highlight of execution. But I have a main case statement in the loop that either allows the state machine to execute a loop or hides them and that case is triggered for no steps to true or false. So that was the reason why I sent the first e-mail because I could see this case change, but not the smallest. But if this is the fix well I'll run with it and lets see case statement switch the highlight of the performance.

Thanks again.

How can you change a menu drop-down menu in a case statement?

Hello

I'm trying a table find vi. This VI will be an existing xml file and once the user has selected access to its equipment, input, output and frequency it put all of these options in a string and search the XML for this exact table name and post it on one screen of output. The problem I have is my entry and exit selection must be a little different depending on the chosen equipment. I thought I could use an instruction box to change the options of selectable input and output, but I ran into snags a lot with it. For whenever I have to put a new drop of entry and exit in the drop-down menu in the case statement, he wants to put a new one in the front (I only want to enter and exit not only three I have two inputs and outputs hidden right now). I think I'm using the wrong case statement... Can someone help change my input and output, selectable options depending on the chosen equipment. Attached is my xml file, Array Find.vi (the original) and table Find_Test.vi (that's what I'm trying to change).

Thank you

dlovell

Hi dlovell,

A few changes in the attached VI:

Requirements/possible Solutions
- When the value of the equipment, do something
- - Add the cases to the value of equipment change event
- Do something = decide what channels to write, to change the input and output strings
- - Read material value changed
  - Decision (case structure)
  - Channel (same method as the previous mod)
Hope this helps
