In Line CASE Statement OR Function

Hi Gurus,
What approach do you typically take in queries where you need to run CASE/DECODE type logic on a query? Obviously for small logic sets DECODE or CASE is fine in the query, but when I have to run a lot of logic for a column output I tend to prefer the FUNCTION. The problem with that approach is the performance. I have read about Function Based Indexes, but they seem to be more for FUNCTIONS that would go against a Single table (i.e. UPPER(CustomerName)).
I would greatly appreciate any info/comments about how to approach this. What I am finding is that in my initial phases of a project my current query(s) are fine, but then as time passes more and more logic needs to be applied and my CASE/DECODES become very hard to maintain.
Thanks,
S

You are correct they are user defined functions. I will take a look at the link you provided....thanks for the info.
Your statement about he data model is what is basiclaly the problem. I have to look at all kind of identifiers, values to determine things like Shipping Rates, Pricing, Qty, etc. What started out as not being that bad has turned into a real headache to try and maintain the logic.
I was trying to implement some user defined FUNCTIONs to break the logic out of the base queries thinking that would help make the code more maintainable, but have started to encounter some performance issues.

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

Using a scalar user defined function in a select case statement

I have a simple select statement below and I want to have a case statement for some conditions based on the result of the udf returned value. I then want the returned value from that specific case statement to be returned where i have indicated 'DISPLAY
ZIPCODE' below.
SELECT
   CASE
         WHEN (SELECT Top 1 ZipCode FROM ufn_GetAddressByBusinessEntityIDandAddressTypeID(table1.BusinessEntityID,712) IS NOT NULL THEN 'DISPLAY ZIPCODE'
         WHEN (SELECT Top 1 ZipCode FROM ufn_GetAddressByBusinessEntityIDandAddressTypeID(table1.BusinessEntityID,714) as r) IS NOT NULL THEN 'DISPLAY ZIPCODE'
         ELSE NULL
       END as Zipcode,
FROM
table1

SELECT COALESCE(ufn_GetAddressByBusinessEntityIDandAddressTypeID(table1.BusinessEntityID,712),ufn_GetAddressByBusinessEntityIDandAddressTypeID(table1.BusinessEntityID,712)) AS Zipcode
FROM table1
Nope. This is two function calls. coalesce(a, b, c, ...) is just syntatic sugar for
   CASE WHEN a IS NOT NULL THEN a
WHEN b IS NOT NULL THEN b
WHEN c IS NOT NULL THEN c
   END
But if you use isnull it's a different matter. (But isnull() permits two arguments.)

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.

know the reason why decode is not working, I heard some where Case statement do not work with 8i.
Does this mean you are using 8i? Then scalar sub queries - selects within the select list, are not supported, along with CASE in PL/SQL.

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

CASE Statement error in function -- Please help!

Hi All,
I created a function in my report.
It has a SQL query similar to the one below. The query works fine in SQL plus.
It has a CASE statement. I am getting error at line4 at the select statement. Error is: "Encountered symbol 'SELECT'....."
Can we use CASE statements like this in reports that use SELECT statements for RETURN EXPRESSIONS. Do we have to do any special?
Can someone help me out of this trouble?
THanks in advance.

MDX -Children count function Not working in Case statement

Hi,
I am trying to create set when you slice with the Hierarchy member is leaf level , I want a output only that Leaf level .
and When I slice with the parent level , it has to give all the members below that parent level.
But the problem here is when I select child member or leaf member , The first condition in the Case is not working
WITH SET
TESTSET AS
CASE
WHEN
[Dimension].[Hierarchy].currentmember.children.count<0
THEN
[Dimension].[Hierarchy].currentmember
ELSE
DESCENDANTS([Dimension].[Hierarchy].Currentmember,,AFTER)
END
SELECT
WBSSET ON 1,
{} on 0
FROM
(SELECT {[Dimension].[Hierarchy].&[10]} ON COLUMNS FROM [CubeName])
Thanks,
Santosh

Hi Santosh,
I don't think Children count function not working in case statement, I have tested it on my local environment, here s the sample query for you reference.
with member
testset as
case
when
[Geography].[Geography].currentmember.children.count<10
then "X"
else "OK"
end
select testset on 0,
{[Geography].[Geography].[Country].members} on 1
from
[Adventure Works]
In your scenario, the issue might be caused by the query isself, you can try to use IsLeaf Funcion to achieve your requirement. Please refer to the links below.

How to use Substring function with Case statement.

Hello Everyone,
I have one requirement where I have to use substring function on the field for report criteria.
E.G.
I have Branch Name Field where I have all branch names information, Now some of the branch names are too big with some extension after the name .
now i want to substing it but the character length varies for each branch.
so is there any way where we can use case statement where we can define that if branch name character are exceeding some value then substing it with this length.

Try something like this:
CASE WHEN LENGTH(tablename.Branch_Name) > n THEN SUBSTRING(...) ELSE tablename.Branch_Name END
where n is the number of characters you want to start the break.

Turn a case statement into a function

I have a case statement (from an earlier post - thank you) that works. I was wondering if it could be edited and change into a function instead. I think it would be cleaner. The variable is set in the Form Properties (pCounterA).
switch (pCounterA.value)
    case "1":
    profileA__1image.rawValue = profileA_1image.value.image.value;
    pCounterA.value = "2";
    break;
    case "2":
    profileA__1image.rawValue = profileA_2image.value.image.value;
    pCounterA.value = "3";
    break;
    case "3":
    profileA__1image.rawValue = profileA_3image.value.image.value;
    pCounterA.value = "4";
    break;
    case "4":
    profileA__1image.rawValue = profileA_4image.value.image.value;
    pCounterA.value = "5";
    break;
    case "5":
    profileA__1image.rawValue = profileA_5image.value.image.value;
    pCounterA.value = "1"; // loops back to the first image
    break;

Hi,
If you insert a script object by right clicking on the root container (often "form1"). It will appear unnamed in the root / variables in the hierarchy.
First of all you should name the script object, staying away from reserved names, eg "this". Say "myScripts"
Script objects can only contain Javascript, so you would need to convert FormCalc scripts (not an issue in your case).
When you go into the script object, you start off a function with "function" followed by its name and inputs in brackets. The extent of the function is given by curly brackets:
function changeImage(vCounter)
     switch (vCounter)
         case "1":
         profileA__1image.rawValue = profileA_1image.value.image.value;
         pCounterA.value = "2";
         break;
     } // close switch statement
} // close function
Back in the form you can call the function by referencing the name of the script object and the name of the function.
myScripts.changeImage(pCounterA.value);
A couple of things to note:
The input in the script can refer to an objects value or a global variable, but in the function you can assign it s different name. So above the input pCounterA.value is EQUAL to vCounter in the function;
You can have several inputs in the call for the function separated by commas;
Don't have the same name for the script object AND the function
Hope that helps,
Niall

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.

CASE statement in a dynamic page

I have written a query using a CASE statement in the select portion to evaluate column values and produce a text string. The query runs fine in sql*plus, but when I attempt to add the code to a dynamic page and compile it, I get the following error message:
ORA-06550: line 1, column 720:
PLS-00103: Encountered the symbol "CASE" when expecting one of the following:

I am running oracle 8.1.7.1.0 using Portal 3.0.9.8.1
I have written a function as a workaround, but would like to know why portal does not seem to like the "CASE" statement.
Any suggestions would be greatly appreciated.

Hi Chetan,
I still get an error message even when I attempt to create a small dynamic page with your cursor. The error message is posted below. I am definitely putting the cursor declaration between <ORACLE></ORACLE> tags. Any Ideas?
Thanks,

Question about case statement

It looks like for the case statement in Linux shell script, it the first condition meet, it won't execute the next anymore, it would exit.
so, for the code like the following, I wonder if there is anyway to output there lines if the $NUM is 0:
case $NUM in
     1 | 0) echo "one or zero" ;;
     2 | 0) echo "two or zero" ;;
     3 | 0) echo "three or zero" ;;
     *) echo "INVALID NUMBER!" ;;
esacexpect output:
one or zero
two or zero
three or zerocurrent output:
one or zero

Every case statement must be terminated with ";;"
http://tldp.org/LDP/Bash-Beginners-Guide/html/sect_07_03.html
What's wrong with using functions as I outlined earlier? It safes you typing repeated commands, if that is what you are trying to accomplish. Alternatively you could also construct a case statement using an if-then clause. Unfortunately Unix shell does not have a "goto" statement, which would make it sometimes easier to control work-flow.
For instance:
$ ./test 1
0 or 1
$ ./test 2
0 or 2
$ ./test 3
0 or 3
$ ./test 0
0 or 1
0 or 2
0 or 3
$ cat ./test
NUM=$1
if [ $NUM = 1 ] || [ $NUM = 0 ]; then
   echo "0 or 1"
fi
if [ $NUM = 2 ] || [ $NUM = 0 ]; then
   echo "0 or 2"
fi
if [ $NUM = 3 ] || [ $NUM = 0 ]; then
   echo "0 or 3"

Using case in a function

Hi,
I have a fuction that accepts one input parameter, called v_inp. And this is the code of the function that i see in the code editor:
--initialize variables here
V_OUTPUT NUMBER;
-- main body
BEGIN
case v_INP
when 15,16,17,18,19 then V_OUTPUT := 1519;
when 20,21,22,23,24 then V_OUTPUT := 2024;
when 25,26,27,28,29 then V_OUTPUT := 2529;
when 30,31,32,33,34 then V_OUTPUT := 3034;
when 35,36,37,38,39 then V_OUTPUT := 3539;
when 40,41,42,43,44 then V_OUTPUT := 4044;
when 45,46,47,48,49 then V_OUTPUT := 4549;
when 50,51,52,53,54 then V_OUTPUT := 5054;
when 55,56,57,58,59 then V_OUTPUT := 5559;
when 60,61,62,63,64 then V_OUTPUT := 6064;
when 65,66,67 then V_OUTPUT := 6567;
when 1519,2024 then V_OUTPUT := 1524;
when 2529,3034,3539,4044,4549,5054 then V_OUTPUT := 2554;
when 5559,6064 then V_OUTPUT := 5564;*/
end if;
EXCEPTION
WHEN OTHERS THEN
NULL; -- enter any exception code here
RETURN NULL;
END;
When i try to deploy this function i get the following warning:
ORA-06550: line 8, column 9:
PLS-00103: Encountered the symbol "CASE" when expecting one of the following:
begin declare exit for goto if loop mod null pragma raise
return select update while <an identifier>
<a double-quoted delimited-identifier> <a bind variable> <<
close current delete fetch lock insert open rollback
savepoint set sql execute commit forall
<a single-quoted SQL string>
Could someone please explain what am i doing wrong, becouse this code is very similar to code i saw in this document: http://otn.oracle.com/sample_code/products/warehouse/files/case.zip
Thanks for all the answers.

I am guessing you are on version 8i. I don't think CASE is supported in PL/SQL until 9i. Perhaps there is an option somewhere to generate if-then statement instead of CASE statement.

Help: Case statement Error

Hi,
Sorry, I don't know anything about SQL Server.
I do know you should take baby steps, especially when trying something you're not sure how to do.
Get rid of all but one CASE expression, until you know how to make that one work.
When you do get that to work, add one more, as much like the first as possible, to make sure you know how to do two columns in the same query.
Get asomething working, then try adding a little bit to it. When you do have errors, you'll have a much better idea what caused the errror.
It's suspicious that you're using aggregate functions in some places, like this
@v_cur_recoveryrefund = case c.code when '96' then sum(recovery_amount)
          end,but not in the first CASE expressions. You might try <tt>MAX (CASE case c.code when '50' then ... END)</tt>
I also find it odd that you're using <tt>CASE ... SUM (...)</tt> ; in Oracle, that would be very rare. It implies that the same expression will be in the GROUP BY clause.
It's more common to have <tt>SUM (CASE ... END)</tt> , like this:
SUM ( CASE c.code WHEN '96' THEN recovery_amount END )
