Any() in a case statement?

I have a query that utilizes a case statement. The case variable could be 1 of 3 different values, A, B, or C. If it's C I would like to check against all 3 values.
How can I do this?
example
select *
from foo
where 1 = 1
and myVal = (case goo when 'c' then any('a','b','c') when 'b' then 'b' else 'c' end)This errors on the any() saying it's missing expression.. Any ideas?
BTW I'm using Oracle 9i

Try this...
SELECT *
FROM foo
WHERE 1 = 1
AND myVal =
( CASE
WHEN goo = 'c' and goo = ANY ( 'a', 'b' , 'c' )
THEN
'Z' -- whatever it should be
WHEN goo = 'b'
THEN 'b'
ELSE 'c'
END
Bottomline, ANY should be preceded by an operator.

SQL Expression in decode function or case statement?

Can I put SQL expressions in decode function or case statement?
For example,
select le.profile, decode( select count(1) from profile_data where NAME= 'XXXX_AFTER' and object_id = le.profile, 0, 'N', 'Y')
from element le;
or
select le.profile, case WHEN ( select count(1) from profile_data where NAME= 'XXXX_AFTER' and object_id = le.profile) = 0 THEN 'N'
ELSE 'Y'
from element le;
None of the above work.
Can anyone tell me how to make it work?
Is there any workaround?
Thanks,
J

You simply needed and END to your CASE statement;
SQL> with profile_data as (
   select 'XXXX_AFTER' name, 1 object_id from dual),
     element as (
   select 1 profile from dual union all
   select 2 from dual)
select le.profile,
   case WHEN ( select count(1) from profile_data where NAME= 'XXXX_AFTER' and object_id = le.profile) = 0
   THEN 'N'
   ELSE 'Y'
   END new_col
from element le
   PROFILE N
         1 Y
         2 N

CASE not found while executing CASE statement on Submit Form

Hi to all APEX users and developers.
I have several APEX applications and they are all working well, but recently I got one strange exception when I try to submit page:
Session: Fetch session header information
...metadata, fetch page info
...Validate item page affinity.
...Validate hidden_protected items.

Page has more than 120 items (most of them are hidden), so my first thought is that page has problem with posting so many items, but APEX error message doesn't hel me at all. Any help would be very appreciated :)
Almir

Hi Almir,
actually it is the 100 page item limit. See (http://download.oracle.com/docs/cd/E17556_01/doc/user.40/e15517/limits.htm)
I also had a look into the source code and the code at the position where the error gets raised only supports 100 page items.
Can you have a look into the generated HTML code and look if you have a page items which is mapped to p_t101 or a higher number ?
I will file a bug to show a better error message.

Case Statement in Answers Filter

Hi,
I'm trying to build a query in Answers that filters the data returned based on the current month number. If the current month is 1 then we want to show all 12 months, otherwise we want to show months less than the current month. If I use the following:
CASE WHEN extract(month from current_date) = 1 THEN "Calculated Values Monthly"."MONTH" >= 1 ELSE "Calculated Values Monthly"."MONTH" < extract (month from current_date) END
I get the error below. All works fine until I add the CASE.

Can you use a case statement in a filter? If not, what are the other options, if any?
Thx

ThxAccording to your requirements, when the month is January, you want all 12 months; any other number and you want months from 1 to "1 less than the current month number." Yes? Okay, here's what to do:
In the filter on your date column, click on the filter button, convert it to SQL and enter this:
MONTH(tablename.date_column) BETWEEN 1 AND CASE WHEN MONTH(CURRENT_DATE) = 1 THEN 12 ELSE MONTH(CURRENT_DATE)-1 END
Here's the logic:
a) When the current month is January, then the case statement will yield 12 and the filter will be:
WHERE MONTH(tablename.date_column) BETWEEN 1 AND 12 ...or all 12 months.
b) When the current month is any other month, say June, then the case statement will yield one less than the what the month number is, or in this case 5.
WHERE MONTH(tablename.date_column BETWEEN 1 AND 5 ...or all the months from 1 to 5 (Jan through May)
This will give you what you want...

T-sql case statement in a select

When I execute the following t-sql 2012 statement, the "NO Prod' value is not
being displayed from the sql listed below:
SELECT DISTINCT
IsNull(cs.TYPE,'') as type,
CASE IsNull(Course.TYPE,'')
WHEN 'AP' then 'AP Prod'
WHEN 'IB' then 'IB Prod'
WHEN 'HR' then 'HR Prod'
WHEN '' then 'NO Prod'
END AS label
FROM CustSection cs
INNER JOIN dbo.Person p on P.personID = cs.personID
Left join customCustomer cs564 on cs564.personID = p.personID and
cs564.attributeID ='564'
   where ( cs.type is null and cs564.attributeID = null)
     or
    (cs.type IN ('HR','AP') OR
      (cs.type='IB' AND SUBSTRING(cs.code,1,1)='3'))
ORDER BY label
What I want is for 'NO Prod' to be displayed when
cs.type is null and cs564.attributeId is null.
Thus can you tell me how to fix query above so the 'NO Prod' value is displayed in the
select statement listed above?

There is no CASE statement in SQL; we have a CASE expression. We do not use the old 1970's Sybase*- ISNULL(); we have COALESCE().
There is no such thing as a magic generic “type” in RDBMS. There is no such thing as a generic “code” in RDBMS. They have to to be “<something in particular>_type” and “<something in particular>_code” in a valid data model. How about blood_type
and postal_code??
There is no such thing as a generic “person” table in RDBMS. First of all, do you really have only one person, as you said?? But the important point is that these persons play a role in the data model – customers, students, etc. You are doing the wrong thing
and doing it badly. This table should not exist any more than a table of “Things” such exist.
And the reason you are beyond any real help is “attribute_id” which tell us that your schema is a total disaster of data and meta data mixed together in a non-RDBMS written in awful SQL. Based on cleaning up bad SQL for 30 years, it looks like you are an OO
programmer who never unlearned his prior mindset.
Why did you allow an encoding schema with blanks? Why do you have so many NULL-able columns?
SELECT DISTINCT is very rare in a properly designed schema. The DRI references assure that rows cam be matched. To get you started, look at this skeleton:
CREATE TABLE Products
(product_gtin CHAR(15) NOT NULL PRIMARY KEY,
product_type CHAR(2) DEFAULT 'XX' NOT NULL
CHECK (product_type IN ('AP', 'IB', 'HR', 'XX'))
The table name is a plural noun because it models a set (NOT an OO class).
The GTIN is an industry standard identifiers, and not have to invent our own.
The product_type (not blood_type, not automobile_body_type!) has a constraint that assures it is never NULL and never blank; I invented 'XX' as a default.
You need more help than you can get in a forum, but if you will follow Netiquette and post the DDL, we can get you started.

CASE Statement in a SELECt

I want to do something like this in a SELECT where I set the value of one field based on another. Is this possible. If not are there any alternatives? Thanks
CASE WHEN [var_cpnt_brkpt_ct] = '0' THEN [enrc_cpnt_var_price_rt] = '0'

There is no CASE statement in SQL; we are a declarative language. We have a case expression! There is no control flow, like you are trying to write. You do not even know that fields are columns. This is as silly
as asking for the color the feathers on a fish.

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> /
AGE_G AGE_COUNT
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.
- - - - - - - - - - - - - - - - Code begins here - - - - - - - - - - - -
set serveroutput on
declare
achar char(1) := '&achar';
begin
case
when achar = 'A' then dbms_output.put_line('The description was
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
declare
achar char(1) := '&achar';
description varchar2(20);
begin
description :=
case
when achar = 'A' then 'Excellent'
when achar = 'B' then 'Very Good'
when achar = 'C' then 'Good'
when achar = 'D' then 'Fair'
when achar = 'F' then 'Poor'
else 'No such grade'
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.
- - - - - - - - - - - - - - - - Code begins here - - - - - - - - - - - -
set serveroutput on
declare
anum1 number := &anum1;
anum2 number := &anum2;
answer number;
begin
case anum1
when 1 then case anum2
when 1 then answer := 10;
when 2 then answer := 20;
when 3 then answer := 30;
else answer := 999;
end case;
when 2 then case anum2
when 1 then answer := 15;
when 2 then answer := 25;
when 3 then answer := 35;
else answer := 777;
end case;
else answer := 555;
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.
- - - - - - - - - - - - - - - - Code begins here - - - - - - - - - - - -
set serveroutput on
declare
anum1 number := &anum1;
anum2 number := &anum2;
answer number;
begin
answer :=
case anum1
when 1 then case anum2
when 1 then 10
when 2 then 20
when 3 then 30
else 999
end
when 2 then case anum2
when 1 then 15
when 2 then 25
when 3 then 35
else 777
end
else 555
end;
dbms_output.put_line('The answer is ' || answer);
end;
- - - - - - - - - - - - - - - - Code ends here - - - - - - - - - - - -
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.
Reference Ducumment
Oracle 8.1.7 Manual
NOTE:131557.1

I 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.

Hello,
Any one can help me that how to use case statment in Oracle forms 6i.
i have read one thread and there was no proper solution so could any one please let me know to use case statement.
Please also let me know which category i should search for FORMS 6i.

hello Andreas,
It is ok but i dont have to use view there.
i need to use without view, because this code has to be use in FORMS6i.
But Forms6i doesn't support to case function. i'm newbie in Forms.
If you can convert to below bold one portion(case) into decode then please help me or
if you have any idea about Forms6i then please send me any link where is given explanation about excel report that how to make excel report through Forms6i step by step and that excel report should be generate on any dynamic path which is given by user:-
cursor c1 is

CASE Statement is not working Derived table

in the bello SQL Statement case statement is not working in derived table. I am new to creation of derived table if any body knows plz kinldy help me out on this.

Thanks

It looks like SQL Server or Sybase given that you're using getdate().
As such, Vinesh's comment to use decode is wrong - decode is Oracle syntax.
Looking at your statement again, I've noticed the following:
you have no { to match the first } - not sure why you're using them anyway.
you haven't given x.market a name - use x.market as market instead
use coalesce instead of nullif if you're on SQL Server.

CASE statement in SQL Server

I am working on a project for ambulance response times. In
the following query which is in my coldfusion code, I am using a
CASE statement on a subquery to count the ambulance response times
in bins. An ambulance should arrive at an emergency incident in
less than 8:59 (539 seconds) or else it is considered late. In my
coldfusion Transact-SQL code I am:
1.) doing a subquery.
2.) counting the 'event numbers' based on the time it took
for the ambulance to arrive.
3.) only counting Lee County ambulances and excluding A6 type
calls (non-emergencies).
4.) grouping it by the dateparts.
SELECT DATENAME("M", I.I_tTimeDispatch) as mths,
(DATEPART("yyyy", I.I_tTimeDispatch)) AS yr,
COUNT(CASE WHEN (DATEDIFF("S",I.I_tTimeDispatch,
I.I_tTimeArrival)) BETWEEN 0 AND 539 THEN evnt END) AS OnTime,
COUNT(CASE WHEN (DATEDIFF("S",I.I_tTimeDispatch,
I.I_tTimeArrival)) BETWEEN 540 AND 1028 THEN evnt END) AS Late,
COUNT(CASE WHEN (DATEDIFF("S",I.I_tTimeDispatch,
I.I_tTimeArrival)) > 1028 THEN evnt END) AS Outlier
FROM (SELECT I_EventNumber AS evnt, I_tTimeDispatch,
I_tTimeArrival, I_kTypeInfo, I_Agency FROM dbo.IIncident) as I
INNER JOIN dbo.ITypeInfo AS T ON I.I_kTypeInfo =
T.ITI_TypeInfo_PK
WHERE I.I_Agency='LC'
AND T.ITI_TypeID NOT LIKE 'A6*'
GROUP BY (DATEPART("M", I.I_tTimeDispatch)), (DATENAME("M",
I.I_tTimeDispatch)), (DATEPART("yyyy", I.I_tTimeDispatch))
ORDER BY (DATEPART("yyyy", I.I_tTimeDispatch)) ASC,
(DATEPART("M", I.I_tTimeDispatch)) ASC
Here is my problem!
I go into Microsoft Access to verify my statistics and I get
different counts. For instance, in April 2008 my coldfusion query
returns 3,944 on-time ambulance responses. My Access query for the
same time period using only Lee County ambulances and excluding A6
non-emergencies returns only 3,805 responses. This is an undercount
of 139 responses. Even for my other time bins I am getting an
undercount.
Here is my Access SQL for the on time response bin (<539
seconds or 8:59):
SELECT Count(dbo_IIncident.I_EventNumber) AS
CountOfI_EventNumber
FROM dbo_IIncident INNER JOIN dbo_ITypeInfo ON
dbo_IIncident.I_kTypeInfo = dbo_ITypeInfo.ITI_TypeInfo_PK
WHERE (((dbo_IIncident.I_Agency)="lc") AND
((dbo_ITypeInfo.ITI_TypeID) Not Like "a6*") AND
((dbo_IIncident.I_tTimeDispatch) Between #4/1/2008# And #5/1/2008#)
AND
((DateDiff("s",[dbo_IIncident]![I_tTimeDispatch],[dbo_IIncident]![I_tTimeArrival]))
Between 0 And 539));
How could two queries that are supposed to be doing the same
thing return such different results?
To clear up any confusion I am temporarily posting the page.
Please look at it because it may help you visualize the problem.
http://lcfcfn01/Secure/GTandLT_8_59.cfm

Thank you for your quick reply.
I thought about that, but it isn't what is causing the
discrepancy in the numbers. This is because Access is hitting the
SQL Server through ODBC. The time stamps in SQL Server are ODBC
datetime stamps so they look like this: 4/19/2008 6:20:18 PM
When my query uses the date #5/1/2008# it is like saying May
1, 2008 00:00:00. Please correct me if I am wrong. The query won't
return any results from May 1, 2008 because it stops at zero
hundred hours. I believe it will only go to April 30, 2008 23:59:59
and then stop there.
I do try and play with the date ranges and the 'seconds'
(<539 or >539) parameter and I consistently get different
results from what my coldfusion page is telling me.

Need help in this query using Case Statement

I have the following query which is currently existing and I am adding few more conditions based on the new requirements which is based on a particular flag set as 1 or 0.
If it is set to 1 then I should use the old query as it is and if it is set to 0 then I should add the new conditions.
Basically when the flag is set to 0, I shouldnt be including some of the records that already exists and should include only new records. This is based on the plan_type_ids in (1,2,3,4).
Hence I am using the Case statement to check if the plan_type_id is in (1,2) then do a set of not exists and if the plan_type_id in (3,4) then do set of not exists.
But when I run this query it is giving me error. What am I doing wrong?
Is there any other simple way to combine all the not exists for all of those select statements as given after the line ------------------------- into a single one?
What am I doing wrong?
I tried putting the NOT EXists before the case too but that too didnt work.
Please help. Appreciate it.
Thank you in advance.

Sql case statement with link not opening new window

Apex 4.2
I am writing a query that has a case statement. I need the case statement to open up a new window, not a new tab. I have the following:
SELECT
case when SCHED_ID = 1 then
'<a href="javascript:popupURL(''http://www.google.com'')">LINK</a>'
end as MyLink
FROM Table_Name
When I plug this into a a column link in the URL field under a page item or report item, then a popup window appears. However, inside the query I am getting a new tab.
ANy help on this matter would be great. Thanks in advance.

Hi,
Try adding a target attribute to you link:
'<a href="javascript:popupURL(''http://www.google.com'')" target="_blank">LINK</a>'

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)

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 Oracle Query.

Hello Oracle Gurus,
I need suggestion on whether I should use Case statement in Oracle queries.
I have a sql statement which inserts the data by selecting data from other table. While selecting the data I have put a logic in the select statement for one column which is something like this and there are some more similar statements in the same query.
CASE
               WHEN (b.ACCOUNT = 'FIN' or b.ACCOUNT ='FIN ACC' or b.ACCOUNT like '%Global Eq%' or b.ACCOUNT like '%Flexible Bond%')
               THEN
                    'MTM'
                         WHEN (substr(a.CTC,-3)='MTM')
               THEN
                    'MTM'
                         WHEN (substr(a.CTC,-3)='AFS' or substr(a.CTC,-3)='HTM' OR substr(a.CTC,-3)='ACC' OR substr(a.CTC,-3)='HFI' )
               THEN
                    'ACC'
               ELSE
                              'OTH'
          END,
I wanted to get an suggestion about how much performance issue can I have due to this in my insert statement.
Let me know if you need any other information.All comments are really appreciated.

Hi,
It's depends on the joins how you have performed with source table, stats and existing of indexes. If the volume of data is high - in case of any performance issue - why can't you perform the required things of logical conditions of data and popualte in one cluster so - that you can fetch out the chunks of required information with better way and in support with indexes.
Let us know the ful query your working on
