"in" clause in case statement

Hello,
I want to do something like this:
     select * from ....
        join ....
      where ....
        and case when pparameter = 'D' then (a.column in ('M', 'P'))
                 when pparameter = 'N' then (a.column in ('N', Z'))
            end case
pparameter is a formal parameter in my procedure, so it does not belong to any table.
Is it possible to do something like this, using case? I did not find any examples like this..
Thank you

Cunning - here's the effect on my trivial example, it's similar to the previous one, but liable to become CPU intensive if the IN-list grows to any great length:
select

t1

id < 20
and (:n1,flag) in (

(2,3),

Evaluation of condition clause in whehe clause using case statement

Hi,
I have a scenario where in I have to evaluate two different conditions based on the parameter value. Is it possible to evaluate the conditiond based on the parameter value with case statement in where clause.
Example:
select A,B,C,D from X,Y,Z
where
cond1 and
cond2 and
case when param='T' then cond3 else cond4 end
Here param is an external parameter passed to the query.
cond3 is something like Y.deptno in(10,30,50,70)
cond4 is something like Y.deptno in (20,40,60,70,80,90)
Your responce will be appriciated.

You can place the case statement as a condition, however it depends what context you want it in, for example;
this will work:
1* select 1 from dual where (case when 1=1 then 1 end) = 1 and 2=2
QL> /
1
1but this will not;
SQL> select 1 from dual where case when 1=1 then 1 end and 2=2;
select 1 from dual where case when 1=1 then 1 end and 2=2
ERROR at line 1:
ORA-00920: invalid relational operatorSo, if you're expecting the condition to evaluate to a true/false, so if you mean soemthing like
when TRUE, then it won't work!

NOT IN clause in CASE statement condition not working

Dear Friends,
I want to use below condition in WHERE clause of my SELECT statement.
WHERE <...........>
<...........>
AND eihf.exr_aip_asset_sid NOT IN
(CASE when safa.fund_relation = 'C' and safa.fund_account_code != vFundAccount
THEN (37874,37909,43424,55040,59513,59598,58570,76148,75885,75927)
ELSE
(0)
END
But it gives me an error as "missing right parenthis".
Please help.

CASE returns one and only one value. It can't return a list. Your satement should be something like:
WHERE <...........>
<...........>
AND (
             safa.fund_relation = 'C'
         AND
             safa.fund_account_code != vFundAccount
         AND
             eihf.exr_aip_asset_sid NOT IN (37874,37909,43424,55040,59513,59598,58570,76148,75885,75927)
     OR
         NOT (
                  safa.fund_relation = 'C'
              AND

Looking help in Default clause with CASE statement ?

I have a table perform(timings date , Mor_Eve varchar2(20) )
Requirements is
(a) If time in timing column is < 12:00 then automatically insert 'MORNING' in Mor_Eve column
ELSE
automatically insert 'EVENING' in Mor_Eve column.
Is there any way of using default clause in create table that insert Morning or Evening in the Mor_Eve column automatically depending on the Timings column ?

Hi,
Welcome to the forum!
All the responses above are good.
Why do you need to store this at all?
If you want to display it automatically, create a view, like this:
CREATE OR REPLACE VIEW     perform_v
AS
SELECT     timings
,     CASE     TO_CHAR (timings, 'AM')
         WHEN 'AM'     THEN 'MORNING'
         WHEN 'PM'     THEN 'EVENING'
               ELSE 'NOT ENTERED'     -- Skip this line if you want NULL
     END     AS mor_eve
FROM     perform
;Always do DML on the table, but query the view when you want to see mor_eve.
I'm not saying there's no reason to store this; I'm just asking if you have one.
If you must store it, a DEFAULT clause won't work.
Starting in Oracle 11, you can have a virtual column. (You can have an index on a virtual column, but why would you want an index on a column that only had 2 values?)
In any version, you can write a trigger that autmoatically populates the mor_eve column whenever you INSERT or UPDATE.

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,
user642297 wrote:
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)

Hello,
I have an APEX application that I need to build a SQL statement for a LOV (List of Values). I have a hidden filed that contains the customer type which can be an 'R' or 'B'. The query needs to be able to display two different result sets based on the customer type of 'R' or 'B'.
If the customer type is 'R' then:
SELECT drg_descr d, drg_code r
FROM distance_ranges
WHERE drg_min_miles IN (0,5)
ORDER BY drg_min_milesIf the customer type is 'B' then:
SELECT drg_descr d, drg_code r
FROM distance_ranges
WHERE drg_min_miles IN (0,5,10,15,20)
ORDER BY drg_min_milesCan someone help me with what I think needs to be a case statement?
Thanks,
Joe

Hi,
You can try CASE statement with WHERE clause
SELECT drg_descr d, drg_code r
FROM distance_ranges
WHERE (CASE param_cust_type
WHEN(param_cust_type='R') THEN (drg_min_miles IN (0, 5)
WHEN (param_cust_type='B') THEN (drg_min_miles IN (0,5,10,15,20)
END;
Please try and let me know if anything wrong.
Anyone from the forum comment my code if there is any wrong.
Thanks!

Case statement in order by clause

Hi,
I have written the below query which is having CASE statement in ORDER BY clause. Please let me know what mistake i have done in the query because am getting "Missing Keyword" Error.
SELECT opn_quest_id, seq_nbr
FROM opinion_question
order by case when :p=1 then
opn_quest_id,seq_nbr
else
opn_quest_id
end;
Thanks,
Santhosh.S

Try Ignore the following solution.
SELECT   opn_quest_id, seq_nbr
FROM   opinion_question
ORDER BY   CASE
WHEN : p = 1 THEN opn_quest_id || seq_nbr
ELSE opn_quest_id
END;
What are the data type of the corresponding columns used in the CASE Statement? I have assumed it to be strings.

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 *

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?
Thanks

How do I use the CASE statement in the where clause?

Hello Everyone,
I have 2 queries that do what I need to do but I am trying to learn how to use the CASE statement.
I have tried to combine these 2 into one query using a case statement but don't get the results I need.
Could use some help on how to use the case syntax to get the results needed.
thanks a lot
select segment_name,
product_type,
count (distinct account_id)
FROM NL_ACCT
where
ind = 'N'
and
EM_ind = 'N'
and product_type in ('TAX','PAY')
and acct_open_dt between (cast('2006-01-17' as date)) and (cast('2006-01-17' as date) + 60)
GROUP BY 1,2
order by product_type
select segment_name,
product_type,
count (distinct account_id)
FROM NL_ACCT
where
ind = 'N'
and
EM_ind = 'N'
and product_type not in ('TAX','PAY')
and acct_open_dt between (cast('2006-01-17' as date)) and (cast('2006-01-17' as date) + 30)
group by 1,2
order by product_type

Something like:
SELECT segment_name, product_type,
       SUM(CASE WHEN account_id IN ('TAX','PAY') and
                     acct_open_dt BETWEEN TO_DATE('2006-01-17', 'yyyy-mm-dd') and
                           TO_DATE('2006-01-17', 'yyyy-mm-dd') + 60 THEN 1
                ELSE 0 END) tax_pay,
       SUM(CASE WHEN account_id NOT IN ('TAX','PAY') and
                     acct_open_dt BETWEEN TO_DATE('2006-01-17', 'yyyy-mm-dd') and
                           TO_DATE('2006-01-17', 'yyyy-mm-dd') + 30 THEN 1
                ELSE 0 END) not_tax_pay
FROM NL_ACCT
WHERE ind = 'N' and
      em_ind = 'N' and
      acct_open_dt BETWEEN TO_DATE('2006-01-17', 'yyyy-mm-dd') and
                           TO_DATE('2006-01-17', 'yyyy-mm-dd') + 60
GROUP BY segment_name, product_type
ORDER BY product_typeNote: You cannor GROUP BY 1,2, you need to explicitly name the columns to group by.

Case statement with group by clause

SELECT STP, CASE WHEN Alternate IS NULL THEN 3 ELSE 4 END as Ind,
CASE WHEN Alternate IS NULL THEN 'New Address' ELSE 'New Location' END as Description , Count(*) Rec_Cnt
FROM t_Ids
group by STP, CASE WHEN Alternate IS NULL THEN 3 ELSE 4 END, CASE WHEN Alternate IS NULL THEN 'New Address' ELSE 'New Location'
ORDER BY 1,2,3
I need a query something like this. Does anyone has any idea on this???

You're missing the END on the GROUP BY Case statement, but otherwise this looks fine.
What problem are you having?
Also, please post DDL
Thanks
Carl

Case statement in OWB mapping

I am trying to use a case statement in an OWB mapping. I am attempting to use it in expression builder within a filter object. Each time I try to validate the expression in the expression builder I get an error:
Line 4, Col 6:
PL/SQL: ORA-00920: invalid relational operator
Below is the code used in the expression builder window:
CASE A.ATTRIBUTE_NAME
WHEN 'CA COMPLETION DATE' THEN RTRIM(A.C_CODE_VALUE)
ELSE NULL
END
Any help with what is happening would be appreciated.
Thank you.
Matt

Thank you both for you help. I initially tried to use the expression operator but was confused since the expression builder in the expression operator has the drop down list with the available SQL clauses greyed out. In the OWB documentation it states that the drop down will contain SQL clauses that are appropriate for that expression type so when I saw it was greyed out I assumed that those clauses where not valid for this operator. Sure enough though when I pasted in my Case statement it verified correctly.
Thanks again,
Matt

Case Statement in Analytic Function SUM(n) OVER(PARTITION BY x)

Hi Guys,
I have the following SQL that doesn't seem to consider the When clause I am using in the case staement inside the analytic function(SUM). Could somebody let me know why? and suggest the solution?
Select SUM(Case When (A.Flag = 'B' and B.Status != 'C') Then (NVL(A.Amount_Cr, 0) - (NVL(A.Amount_Dr,0))) Else 0 End) OVER (PARTITION BY A.Period_Year) Annual_amount
     , A.period_year
     , B.status
, A.Flag
from A, B, C
where A.period_year = 2006
and C.Account = '301010'
--and B.STATUS != 'C'
--and A.Flag = 'B'
and A.Col_x = B.Col_x
and A.Col_y = C.Col_y
When I use this SQL, I get
Annual_Amount Period_Year Status Flag
5721017.5 --------- 2006 ---------- C -------- B
5721017.5 --------- 2006 ---------- O -------- B
5721017.5 --------- 2006 ---------- NULL ----- A
And when I put the conditions in the where clause, I get
Annual_Amount Period_Year Status Flag
5721017.5 ---------- 2006 ---------- O -------- B

Here are some scripts,
create table testtable1 ( ColxID number(10), ColyID number(10) , Periodname varchar2(15), Flag varchar2(1), Periodyear number(15), debit number, credit number)
insert into testtable1 values(1, 1000, 'JAN-06', 'A', 2006, 7555523.71, 7647668)
insert into testtable1 values(2, 1001, 'FEB-06', 'B', 2006, 112710, 156047)
insert into testtable1 values(3, 1002, 'MAR-06', 'A', 2006, 200.57, 22376.43)
insert into testtable1 values(4, 1003, 'APR-06', 'B', 2006, 0, 53846)
insert into testtable1 values(5, 1004, 'MAY-06', 'A', 2006, 6349227.19, 6650278.03)
create table testtable2 ( ColxID number(10), Account number(10))
insert into testtable2 values(1, 300100)
insert into testtable2 values(2, 300200)
insert into testtable2 values(3, 300300)
insert into testtable2 values(4, 300400)
insert into testtable2 values(5, 300500)
create table apps.testtable3 ( ColyID number(10), Status varchar2(1))
insert into testtable3 values(1000, 'C')
insert into testtable3 values(1001, 'O')
insert into testtable3 values(1002, 'C')
My SQL:
select t1.periodyear
     , SUM(Case When (t1.Flag = 'B' and t3.Status != 'C') Then (NVL(t1.credit, 0) - (NVL(t1.debit,0))) Else 0 End) OVER (PARTITION BY t1.PeriodYear)
     Annual_amount
     , t1.flag
     , t3.status
     , t2.account
from testtable1 t1, testtable2 t2, testtable3 t3
where t1.colxid = t2.colxid
and t1.colyid = t3.colyid(+)
--and t1.Flag = 'B' and t3.Status != 'C'
Result:
PeriodYear ----- AnnualAmount ----- Flag ----- Status ----- Account
2006 ------------------ 43337 --------------- A ----------- C ---------- 300100
2006 ------------------ 43337 --------------- B ----------- O ---------- 300200
2006 ------------------ 43337 --------------- A ----------- C ---------- 300300
2006 ------------------ 43337 --------------- B ------------ ----------- 300400
2006 ------------------ 43337 --------------- A ------------ ----------- 300500
With condition "t1.Flag = 'B' and t3.Status != 'C'" in where clause instead of in Case statement, Result is (which is desired)
PeriodYear ----- AnnualAmount ----- Flag ----- Status ----- Account
2006 ------------------ 43337 --------------- B ----------- O ---------- 300200

"in" clause in case statement
