CASE in a WHERE clause : ORA-00905

Hi everyone,
I am trying to use a CASE in a WHERE clause and I got the error ORA-00905: missing keyword. Here is my code :
SELECT id_reserv,
     concat(nom,concat('_',indice)) as nom,
     libelle,
     num_lot,
     resa_keyword1,
     resa_keyword2,
     resa_keyword3,
     resa_keyword4,
     date_creation,
     comm_creation,
     id_util,
     actif,
     id_env_act,
     (SELECT login from utilisateur u where u.id_util=r.id_util) AS nom_util,
     (SELECT nom from environnement e where e.id_env=r.id_env_act) AS nom_env,
     (SELECT count(*) from reserv_comp rc where rc.id_reserv=r.id_reserv) AS nbComp,
     (SELECT count(*) from reserv_modif mc where mc.id_reserv=r.id_reserv) AS nbModif
FROM reservation r
     WHERE r.nom NOT LIKE 'RESERV_LOT_%'
     AND id_util='1'
     AND actif='1'
     AND id_env_act>='-1'
     AND CASE sansdemande
     WHEN true THEN id_reserv not in select id_reserv from demande_livraison where id_env_dep>='-1'
     ELSE id_reserv=id_reserv
     END
     AND nom LIKE '%'
ORDER BY date_creation;
I already looked at the CASE statement and it seems that the syntax is correct, so I'm not sure I can use it in a WHERE clause.
Any help would be nice !

Hi,
it should be something like this:
AND CASE
WHEN 'false'='true' THEN (select id_reserv from demande_livraison where id_env_dep>='-1')
ELSE id_reserv
     END = id_reserv The subquery should give one row back
But I think it is better to write your query as:
SELECT id_reserv,
     concat(nom,concat('_',indice)) as nom,
     libelle,
     num_lot,
     resa_keyword1,
     resa_keyword2,
     resa_keyword3,
     resa_keyword4,
     date_creation,
     comm_creation,
     id_util,
     actif,
     id_env_act,
     (SELECT login from utilisateur u where u.id_util=r.id_util) AS nom_util,
     (SELECT nom from environnement e where e.id_env=r.id_env_act) AS nom_env,
     (SELECT count(*) from reserv_comp rc where rc.id_reserv=r.id_reserv) AS nbComp,
     (SELECT count(*) from reserv_modif mc where mc.id_reserv=r.id_reserv) AS nbModif
FROM reservation r
     WHERE r.nom NOT LIKE 'RESERV_LOT_%'
     AND id_util='1'
     AND actif='1'
     AND id_env_act>='-1'
     AND
                      ( 'false'='true' and id_reserv not in (select id_reserv from demande_livraison where id_env_dep>='-1')
                      or
                      ( 'true'= 'true' and id_reserv=id_reserv
     AND nom LIKE '%'
ORDER BY date_creation;This coding in SQL something as if a=b then c, else d in the simplest form.

Case statement in where clause ??

Hello gurus,
Can we use case statements in where clause ?? Any example will be great!
And also i would like to know, besides CASE and DECODE statements, Is there any way we can use IF ELSE statements in SELECT clause or in WHERE clause ?
Thank you!!

Hi,

Hoek,
Thanks for the reply
Whatever you return from 'then' should match your criteria.I didnt get this part...can you elaborate this part ?? Thank you!!Remember what a CASE expression does: it returns a single value in one of the SQL data types (or NULL).
You're probably familiar with conditions such as
WHERE   col = 1Inthe example above, col could be replaced by any kind of expression: a function call, and operation (such as "d * 24") or a CASE expression, which is exactly what Hoek posted:
where case
         when col = 6 then 1
         when col = 9 then 1
       end = 1;I think what Hoek meant about mnatching was this: since the CASE expression is being compared to a NUMBER, then every THEN clause (as well as the ELSE, if there is one) should return the same data type. You can't have one THEN clause return a NUMBER, and another one in the same CASE expression return a DATE, like this:
where case
         when col = 6 then 1
         when col = 9 then SYSDATE     -- WRONG! Raises ORA-00932: inconsistent datatypes
       end = 1;
By the way, it's rare when a CASE expression really helps in a WHERE clause. CASE is great for doing conitional stuff in places where you otherwise can't (in the ORDER BY clause, for example), but the WHERE clause was designed for conditions.
Hoek was just trying to give a simple example. If you really wanted those results, it would be simpler to say:
where col = 6
or     col = 9and simpler still to say
where col IN (6, 9)

How to use CASE stmt in Where clause

How to use CASE stmt in WHERE clause?. I need the code. Please send me as early as possible..........

Hi,
How to use CASE stmt in WHERE clause?. There's no difference between how a CASE expression is used in a WHERE clause, and how it is used in any other clause. CASE ...

CASE expressions aren't needed in WHERE clauses very much. The reason CASE expressions are so useful is that they allow you to do IF-THEN-ELSE logic anywhere in SQL. The WHERE clause already allows you to do IF-THEN-ELSE logic, usually in a more convenient way.
I need the code.So do the peple who want t help you. Post a query where you'd like to use a CASE expression in the WHERE clause. Post CREATE TABLE and INSERT statements for any tables used unless they are commonly available, such as scott.emp). Also, post the results you want from that sample data, and explain how you get those resuts from that data.
See the forum FAQ {message:id=9360002}
Please send me as early as possible..........As mentioned bfore, that's rude. It's also self-defeating. Nobody will refuse to help you because you don't appear pushy enough, but some people will refuse to help you if you appear too pushy.

Case statement within where clause

How can i write a case statement within Where clause of SQL statement.
Ex:
If sysdate is less than Dec 31 of 2009 then run the query for 2009 else run the query for 2010.
belwo query is not working. Please let me know how can i write a case statement within where clause.
Select * from table
where
Case
when to_char(sysdate,'yyyymmdd')<=20091231 then tax_year=2009
else tax_year=2010
End

Hi,
You can get the results you want like this:
Select *
from      table
where   tax_year = Case
                  when to_char(sysdate,'yyyymmdd') <= 20091231
                  then 2009
                  else 2010
             End
;A CASE expression returns a single value in one of the SQL data types, such as a NUMBER, VARCHAR2 or DATE. There is no boolean type in SQL.

Case with where clause - ORA-00920: Invalid relational operator

SELECT concat (year,period)

The problem is the as "MonthNo" - you can't give an "AS" alias to an expression in a where clause.
You have not actually given any condition, just a set of translations from period into a number.
You also haven't said what you're trying to do.
Perhaps you want:
SELECT concat (year,period)
FROM DD_ACTUALS_FACT
WHERE something
ORDER BY CONCAT (year, CASE Period
WHEN 'JAN' THEN '01'
WHEN 'FEB' THEN '02'
WHEN 'MAR' THEN '03'

WHEN 'OCT' THEN '10'
WHEN 'NOV' THEN '11'
WHEN 'DEC' THEN '12'
END ) DESC

No output for XML Publisher Report using CASE/DECODE in Where Clause

Hi,
I've a business requirement to modify an existing report which has two input parameters,
-> p_statcode (Closed Status) which can have values 'Y' or 'N'
-> p_overdue (Overdue Flag) which can have values 'Y' or 'N'
The Overdue Flag is an evaluated column having values of Y/N and it is evaluated as follows,
ONTF_MOD_VAL(NVL (
                                     (TRUNC (SYSDATE)
                                      - (TO_DATE (oe_order_lines.attribute18,
                                                  'DD-MON-RRRR')
                                         + TO_NUMBER (fnd_lookup_values.meaning))),
                                     0
                        overdue_flagThe user requirement now is they needs to be a third option for parameter p_overdue called ALL,
passing which the output should include records having
p_statcode is Y ELSE p_statcode is N AND p_overdue is Y OR p_overdue is N
In other words records having both Y and N vlaues for Overdue Flag have to be returned irrespective of the value given to Closed Status.
Original where clause in the Data Definition file is as follows,
WHERE Closed_Status = nvl(:p_statcode,Closed_Status)
                   AND overdue_flag = nvl(:p_overdue,overdue_flag)My modified code is as follows,
WHERE   Closed_Status = NVL (:p_statcode, Closed_Status)
         AND overdue_flag = (CASE
         WHEN :p_overdue = 'Y' THEN 'Y'
         WHEN :p_overdue = 'N' THEN 'N'
         ELSE overdue_flag
         END)
OR
WHERE   Closed_Status = NVL (:p_statcode, Closed_Status)
         AND overdue_flag = DECODE (:p_overdue, 'Y', 'Y', 'N', 'N',overdue_flag)Both approaches have the same problem.
The output is in EXCEL format. The modified query works fine for p_overdue as Y or N but when p_overdue is passed as ALL it returns an empty EXCEL sheet with just the report output column headers.
Any help as to why this is the case ?? What is wrong in my approach ?
Regards,
Vishal

not clear about p_overdue = ALL
which values needed for p_overdue = ALL ?
try smth like
WHERE   Closed_Status = NVL (:p_statcode, Closed_Status)
AND (
   overdue_flag = DECODE (:p_overdue, 'Y', 'Y', 'N', 'N',overdue_flag) and :p_overdue != 'ALL'
   or
:p_overdue = 'ALL' and (overdue_flag = 'Y' or overdue_flag = 'N')
)for overdue_flag which has more then 'Y', 'N' values
if overdue_flag only in ('Y','N') then
WHERE   Closed_Status = NVL (:p_statcode, Closed_Status)
AND (
   overdue_flag = DECODE (:p_overdue, 'Y', 'Y', 'N', 'N',overdue_flag) and :p_overdue != 'ALL'
   or
:p_overdue = 'ALL'
)

Using :case when in where clause

Hello,
I need some help with using of case statement in a where clause
Table that contains info about employees taking some coursework:
Class (values could be SAP, ORACLE, JAVA)
Code (if Class is SAP then CODE is not null; if class is any other CODE is NULL)
Start Date (date they began class not null)
End Date (date then ended the class - could be null)
Employee Level(numbers from one through five)
I need a single LOV in forms that should show Employee_Level for input class,code,date.
How to do this?
I started off with this but get 'missing statement error'
select distinct employee_level from e_course
   where (
   case when &class='SAP' then code ='1' and start_date > to_date('20000101','YYYYMMDD') and
                                           end_date < to_date('20000101','YYYYMMDD')
           else
               null
   end) order by employee_level;Thanks

Hi,
user469956 wrote:
But all these examples have only one condition for each case.Depending on how you count, all WHERE clauses have only one condition.
I see an example in that thread that has 6 atomic conditions, linked by AND and OR.
I need to check date & code. This is what is causing the error.Why do you want to use a CASE statement?
Why can't you put all your conditions directly iinto a WHERE clause, soemthing like this:
WHERE   (   &class='SAP'
        AND code ='1'
OR      (   start_date > to_date('20000101','YYYYMMDD')
        AND end_date    < to_date('20000101','YYYYMMDD')
        )I said "something like this" because I don't know what you really want to do.

what happens to the ELSE PART?It is for you to tell what happens to the ELSE part.
If the ID is not 1 or 11, then your AND condition fails and probably your query will not retrieve any records for you (Assuming this query is not a part of OR condition, because there is no query provided.).
Because, without ELSE, the default shall be set to NULL and since you used "DATA_CD =", NULL shall not equate with it resulting in failure of condition. Hence, I would suggest you to add some default value in the ELSE part.

I appreciate that there are much simpler ways to run this query but I wondered if anyone else had come across the following -
select distinct

product_table.b,
product_table.c,
CASE WHEN product_table.c IN ('A','AA') THEN 'AAA'
WHEN product_table.b = 'B' THEN 'BBB'

WHEN product_table.b IN ('D','DD') THEN 'DDD'
WHEN product_table.b LIKE 'E%' THEN 'EEE'
WHEN product_table.b LIKE 'F%' THEN 'FFF'
WHEN product_table.b LIKE 'G%' THEN 'GGG'
ELSE 'UNKNOWN' END
from product_table
where
( CASE WHEN product_table.c IN ('A','AA') THEN 'AAA'
WHEN product_table.b = 'B' THEN 'BBB'
WHEN product_table.c IN ('C','CC','CCC') THEN 'CCC'
WHEN product_table.b IN ('D','DD') THEN 'DDD'
WHEN product_table.b LIKE 'E%' THEN 'EEE'
WHEN product_table.b LIKE 'F%' THEN 'FFF'
WHEN product_table.b LIKE 'G%' THEN 'GGG'
ELSE 'UNKNOWN' END) = 'FFF'
when this query runs its as if the where clause = 'FFF' does not exist and all rows are returned.
Thanks, Sarah.

Technical questions should be addressed to one of the technical forums. You'll probably find that the folks in the PL/SQL forum (Products | Database | PL/SQL) have some thoughts.

How to use a case statement in where clause

Hi All,
I have a requirement which is to bring all the claims that are created in the last month.So, i wrote a query something like this
select * from claims
where
(Month(ClaimOpenDate) = Month(Getdate())-1 and year(claimopendate) = year(getDate()))
which would give me any new claims created in last month of current year, but this condition fails if we are in the first month of a new year( lets say if we are in 2016 jan then month(getdate())-1 would be 0 and year(getdate()) would be 2016 so we dont
find any records where year is 2016 and month is 0 for claimopen).
So, i would like to use a case statament or something which can help me get around this one.
Can someone please help me with any suggestions?
Thanks

So if i use your logic in the end for both the where clauses its been more than 10 minutes and the query is still running however if i use my old method it doesnt even take a second. Looks like its affecting the execution plan. Any suggestions to get around
this one please?

Hi I haev issue facing in procedure there are 4 param as in put some time 2 parameter will have value and some time it is null and and one parameter has multiple value . and this value i am passing to cursor and cursor should return value even though value is null so using case satement in where clasue but it is throwing error.
here syntax
SELECT strategicinitiativeid, projectid, -- ltm, ltmdeptid,
YEAR,
SUM (netexpensebudget) netexpensebudget,
SUM (devsoftcapbudget + purchasesoftcapbudget
+ hardwarecapbudget
) AS totalcapbudget,
SUM (netexpensebudgetinprog) netexpensebudgetinprog,
SUM ( devsoftcapbudgetinprog
+ purchasesoftcapbudgetinprog
+ hardwarecapbudgetinprog
) AS totalcapinprogbudget
FROM vpendingprojectsaligntosi
WHERE CASE
WHEN v_projectid IS NOT NULL
THEN projectid IN (v_projectid)
END and case v_SIID is not null
then strategicinitiativeid=v_SIID end
AND budgetstepid IN (v_budgetstepid)
GROUP BY strategicinitiativeid, YEAR, projectid;

Case condition in where clause

Hi
I'm a SQL beginner but according to my reading of the manual, this syntax should be acceptable. I'm using it in application express but tested it also in SQL developer and finding that it fails with an "invalid relational operator" error, with the line number pointing to the ELSE clause of the CASE condition, but a column number pointing to white space.
This is a nested select but that shouldn't matter. The fragment in question is this:
select some columns
from res
where res.villaid = :P605_VILLAID
and INSTR(:P604_RES_STATES, res.states) != 0
and (CASE :P604_EXCLUDE_ZERO
WHEN 'Y' THEN 'res.rate > 0'
ELSE 'res.rate >= 0'
END)
and res.DEPARTDATE > :P605_STARTDATE
and res.ARRIVEDATE <= :P605_ENDDATE,
I hope this formats ok when posted. The code is looking for reservations in a date range (which works fine when the other conditions are commented out), and should only output zero-rate rows (complimentary nights) if the user asks for this in the P604_EXCLUDE_ZERO bind variable. There are probably other ways to go about this, but I am too stubborn to give up on this. Well, not yet anyway.
Thanks and regards

from res
where res.villaid = :p605_villaid
       and instr (:p604_res_states, res.states) != 0
       and sign (res.rate) >= case when :p604_exclude_zero = 'Y' then 1 else 0 end
       and res.departdate > :p605_startdate
       and res.arrivedate <= :p605_enddate

View Variable for WHERE clause "ORA-06550, INTO clause expected"

Hi Guys,
two questions
1. can a view have variables like:
create view myview
As
myname varchar(5) = bob
select * from mytable where name = myname
2. if so, why does a simple select above cause
the error "ORA-06550, INTO clause expected" ?

Hi,
no so direct is not possible. There are workarounds, see this thread on Asktom: [url http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:1448404423206]Parameterized view
