Using Case statement instead of IF in formula fields

Hi,
Can I use Case statement instead of IF in formula fields?If yes,please specify the syntax.
regards,
sunitha

Hi Sunitha,
You can surely use case statement instead of the If statement. The syntax for the case statement is :
Select [1 To n]
Case "Condition a", "Condition b":
"c"
Case "Condition d","Condition e":
"f"
Default:
Hope this helps you!

Need help in this sql query to use Case Statement

hi All,
I have the below query -
SELECT DISTINCT OFFC.PROV_ID
,OFFC.WK_DAY
,CASE
WHEN OFFC.WK_DAY ='MONDAY' THEN 1
WHEN OFFC.WK_DAY ='TUESDAY' THEN 2
WHEN OFFC.WK_DAY ='WEDNESDAY' THEN 3
WHEN OFFC.WK_DAY ='THURSDAY' THEN 4
WHEN OFFC.WK_DAY ='FRIDAY' THEN 5
WHEN OFFC.WK_DAY ='SATURDAY' THEN 6
WHEN OFFC.WK_DAY ='SUNDAY' THEN 7
END AS DOW
,OFFC.OFFC_OPENG_TIME
,OFFC.OFFC_CLSNG_TIME
FROM GGDD.PROV_OFFC_HR OFFC
WHERE OFFC.PROV_ID='0000600'
WITH UR;
this query is bringing results in 6 differnt rows with opening and closing time for each day separately. I want to generate the data in one row with each day having opening and closing time, so for 7 days, total 14 columns with opening and closing time. But i am not able to do that using case statement.
can somebody help me in achieving that.
thanks,
iamhere

Hi,
Welcome to the forum!
That's called a Pivot .
Instead of having 1CASE expression, have 14, one for the opening and one for the closing time each day, and do GROUP BY to combine them onto one row.
SELECT       OFFC.PROV_ID
,       MIN (CASE WHEN OFFC.WK_DAY ='MONDAY'    THEN OFFC.OFFC_OPENG_TIME END)     AS mon_opn
,       MIN (CASE WHEN OFFC.WK_DAY ='MONDAY'    THEN OFFC.OFFC_CLSNG_TIME END)     AS mon_cls
,       MIN (CASE WHEN OFFC.WK_DAY ='TUESDAY'   THEN OFFC.OFFC_OPENG_TIME END)     AS tue_opn
,       MIN (CASE WHEN OFFC.WK_DAY ='TUESDAY'   THEN OFFC.OFFC_CLSNG_TIME END)     AS tue_cls
FROM        GGDD.PROV_OFFC_HR OFFC
WHERE       OFFC.PROV_ID     = '0000600'
GROUP BY offc.prov_id
;This assumes there is (at most) only one row in the table for each distinct prov_id and weekday. If not, what do you want to do? Post a little sample data (CREATE TABLE and INSERT statements) and the results you want from that data.
The staement above works in Oracle 8.1 and up, but there's a better way (SELECT ... PIVOT) available in Oracle 11. What version are you using? (It's always a good idea to include this when you post a question.)

Using case statement in merge when matched

Hi,
I want to use case statement in the when matched clause of merge statement to ensure that I update only those fields that are undated.
create table TEST1
NAME1 VARCHAR2(25),
NAME2 VARCHAR2(25),
ID NUMBER not null
create table TEST2
ID NUMBER not null,
ID2 NUMBER not null,
NAME1 VARCHAR2(25),
NAME2 VARCHAR2(25)
merge into test1 t1
using
test2 t2
ON (t1.id = t2.id)
when matched
then
case
when t1.name1 != t2.name1
then
update set t1.name1 != t2.name1
when t1.name2 != t2.name2
then
update set t1.name2 != t2.name2
else
null;
end
it does not work and raises invalid sql command. Any idea how can I do that?
Thanks.

Hi
In that case you would have to use multiple statements and you may as well just use UPDATE instead of MERGE. Also, are you sure that you aren't trying to to fix a problem that doesn't actually exist.
Think about where the execution time is going to come from...
I would be tempted to do 1 UPDATE like this...
   UPDATE test1 t1
   SET    (t1.name1,
           t1.name2) = (SELECT t2.name1,
                                t2.name2
                        FROM    test2 t2
                        WHERE t1.id = t2.id
                        AND   (t1.name1 != t2.name1
                         OR    t1.name2 != t2.name2))If you get specific performance issue with this, then post an explain plan and trace and I'll have a look.
I don't this the cost of the update is going to be as great as you think.
Cheers

Hi All
Can anyone help me here

As this is hitting same table with the similar set of queries so i was adviced to use case statement by taking the wk_1...5 in variable and making the query better
I am unable to figure out how to proceed.
Appreciate your help here.

Post your table (only the relevant columns as a CREATE TABLE statement) and some sample data (INSERT into) and your required output.

Update using CASE statement

Hi
I have two tables
employee
empid empname empaddress valid
Employeedetails
empid empname manager
I would like to validate empname from both the tables using case statement and empid as join and update 'valid' column in employee table to y/n.
Please help me with the syntax

Hi,
Depending on your requirements:
UPDATE     employee e
SET     valid       = (
                 SELECT CASE
                                 WHEN COUNT (*) = 0
                       THEN 'n'
                       ELSE      'y'
                             END
                 FROM    employeedetails
                 WHERE   empname     = e.empname
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
If you're asking about a DML statement, such as UPDATE, the sample data will be the contents of the table(s) before the DML, and the results will be state of the changed table(s) when everything is finished.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).

Can I use case statements in triggers?

I created this trigger, it works BUT I don't like those parentheses at the begining, I would like
to change those parentheses for case statements, well that is my question, can you use case statements in triggers, how you would translate the following in case statement?
FOR EACH ROW
WHEN ( (new.sgbstdn_levl_code = 'UG')
and
( (NEW. SGBSTDN_STST_CODE NOT IN ('GR','SA','AS','IS') )
OR
( (NEW. SGBSTDN_STST_CODE = 'IS' ) AND
(NEW. SGBSTDN_STYP_CODE IN ('N' , 'T' )) AND
(OLD. SGBSTDN_STST_CODE = 'AS' ) ) ) )
==================================================================================================
CREATE OR REPLACE TRIGGER CC_STUD_WITHDRAWAL
AFTER UPDATE OR INSERT ON SATURN . SGBSTDN
FOR EACH ROW
WHEN ( (new.sgbstdn_levl_code = 'UG')
and
( (NEW. SGBSTDN_STST_CODE NOT IN ('GR','SA','AS','IS') )
OR
( (NEW. SGBSTDN_STST_CODE = 'IS' ) AND
(NEW. SGBSTDN_STYP_CODE IN ('N' , 'T' )) AND
(OLD. SGBSTDN_STST_CODE = 'AS' ) ) ) )

event_code := SUBSTR ( gokevnt.F_CheckEvent ( 'WORKFLOW' ,'CC_STUDENT_WITHDRAW' ),1,20);
OPEN get_stud_name ;

You could delete a fair number of extraneous parentheses.
CREATE OR REPLACE TRIGGER cc_stud_withdrawal
AFTER UPDATE OR INSERT
ON saturn.sgbstdn
FOR EACH ROW
WHEN     NEW.sgbstdn_levl_code = 'UG'
       AND (   NEW.sgbstdn_stst_code NOT IN ('GR', 'SA', 'AS', 'IS')
            OR (    NEW.sgbstdn_stst_code = 'IS'
                AND NEW.sgbstdn_styp_code IN ('N', 'T')
                AND OLD.sgbstdn_stst_code = 'AS'))

Conditional Filters using case statements

Hello,
I have a table view which displays Total Quota and Theatre Quota. Against the Total Quota, there are 2 values - Rollover Revenue and Theatre Revenue. Against the Theatre Quota, there is only Theatre Revenue.
What I want to accomplish is to display only the Rollover Revenue Aggregated Quarterly number whenever there is a Total Quota number and not display the Theatre Revenue number
In the table view,
Year Name     Quarter Name     Quarter Name Sort     Person Region     Quota Name     Quarterly Quota     Credit Amount     QTD Attainment     Credit Type Name
YEAR-2012     QTR-1-2012     QTR-1-2012     750     Total Quota     6,128,500     5,492,081     89.62%     Rollover Revenue Aggregated Quarterly
               750          6,128,500     5,344,000     87.20%     Theatre Revenue
     QTR-2-2012     QTR-2-2012     750     Total Quota     5,922,500     5,890,264     99.46%     Rollover Revenue Aggregated Quarterly
               750          5,922,500     6,120,000     103.33%     Theatre Revenue
     QTR-3-2012     QTR-3-2012     750     Total Quota     5,716,500     0     0.00%
     QTR-4-2012     QTR-4-2012     750     Total Quota     5,510,500     0     0.00%
I used an example in the following link:
http://oraclebizint.wordpress.com/2008/02/06/oracle-bi-ee-101332-conditional-filters-using-case-statements-in-filters/
and applied the example in my scenario:
CASE WHEN Quota."Quota Name" = 'Total Quota' THEN "Credit Type"."Credit Type Name" ELSE 'Dummy' END != 'Theatre Revenue'
I still get duplicate rows.
Thanks.

Could you suggest any solutions for this problem where I can conditionally hide the number only for a certain type of data and not for all type of data?
Thanks.

Checking for the condition types using case statement

hi folks,
I have a lot of condition types that I have to check for and I am using case statement to do that. The code goes like this.
case wac-kschl.
        when 'ZRAT' OR 'ZAGR' OR 'ZRCR' OR
              'Y098' OR 'Y007' OR 'ZREW' OR 'Y106'        OR 'ZTSR' OR 'Y127' OR 'Y125' OR 'Y126' OR 'Y124' OR 'Y157' OR 'Y092' OR 'Y085' OR 'Y090' OR 'ZMZD'
OR 'Y215' OR 'Y214' OR 'Y111' OR 'ZC$D' OR 'ZAUD'.
up till here it is working on errors and when I add few more condition types to the case statement it is throwing the error.
I have to check for all the condition types out here.
How can I correct it? Is there a better way to do it?
thanks
Santhosh

Hi Santhosh,
I think that your CASE statement has a flaw. The line length of one of the lines is too large. You need to insert a carriage-return to shorten it (or press the button 'Pretty Printer').
The code would look nicer like this:[code] CASE wac-kschl.
    WHEN 'ZRAT' OR 'ZAGR' OR 'ZRCR' OR 'Y098' OR 'Y007' OR 'ZREW'
      OR 'Y106' OR 'ZTSR' OR 'Y127' OR 'Y125' OR 'Y126' OR 'Y124'
      OR 'Y157' OR 'Y092' OR 'Y085' OR 'Y090' OR 'ZMZD' OR 'Y215'
      OR 'Y214' OR 'Y111' OR 'ZC$D' OR 'ZAUD' OR 'Z001' OR 'Z002'
      OR 'Z003' OR 'Z004' OR 'Z005' OR 'Z006' OR 'Z007' OR 'Z008'
      OR 'Z009' OR 'Z010' OR 'Z011' OR 'Z012' OR 'Z013' OR 'Z014'.
    Do your thing here
      WRITE: / 'OK'.
    WHEN OTHERS.
      WRITE: / 'NOT OK'.
ENDCASE.[/code]If this will not work for you, you could try a different approach:[code]* Local definition
DATA:
    var_list(1024).
Build variable string for checking
CONCATENATE 'ZRAT ZAGR ZRCR Y098'
              'Y007 ZREW Y106 ZTSR'
              'Y127 Y125 Y126 Y124'
              'Y157 Y092 Y085 Y090'
              'ZMZD Y215 Y214 Y111'
              'ZC$D ZAUD'
         INTO var_list
    SEPARATED BY space.
Check if the correct value is supplied
IF var_list CS wac-kschl.
Do your thing here
    WRITE: / 'OK'.
ENDIF.[/code]Hope this helps you a bit.

Rob.

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.

Using case statement in OWB expression builder

Hi All,
We are using OWB version 10.2.0.1.0. While using the below case statement We are getting the validation message as 'The expression is not properly formed'.
Case statement used in expression builder:
case when (INGRP1.CHARGETYPE in ('O','F') or INGRP1.TARIFF_GROUP in ('SMSINT','MMSINT')or ( INGRP1.CALL_TYPE = '002' and INGRP1.TARIFF_GROUP = 'MTV'))
then
(select call_zone_reltn_key from call_zone_reltn where
call_zone_cd=substr(case
               when substr( INGRP1.B_SUBNO,1,2)='00'
               then
               substr( INGRP1.B_SUBNO,3)
               else substr( INGRP1.B_SUBNO,1)
               end,1,length(call_zone_cd))and rownum=1)
else -1
end
Kindly help me out in fixing this error or suggest any alternate way to use the above query in OWB expression builder.
Thanks,

Did you try to deploy the mapping ? Some time the expression validator gives wrong error messege.
Try to deploy the mapping and see if you are still getting this issue

Using Case statement to insert,update,delete the tables

Hi All,
I have to check the databse ,
if it is developement then
insert/update/delete values in tables;
if it staging then
insert/update/delete values in tables;
if it is production then
insert/update/delete values in tables;
thers is function available to check the current database
For doing the about i am trying to write CASE statement like this
SELECT function,
case
when fun = 'developement' then insert into table1 values ('abcd','1234')
when fun = 'staging' then insert into table1 values ('abcd','1234')
when fun= 'production' then insert into table1 values ('abcd','1234')
else null
from dual
its throughing me an error
please help
Thanks,

Hi,
You can use CASE staement any place where an expression is expected.
For example, in:
UPDATE table_a
SET     col1 = exp1
,       col2 = exp2
WHERE   exp3 = exp4;all the expressions are labled lke expn.
Note that table_a, col1 and col2 are not expressions: you must hard-code these names, or use dynamic SQL.
So it's okay to say:
UPDATE table_a
SET     col1 = CASE
                   WHEN db = 'development' THEN 0
                   WHEN db = 'staging'      THEN 1
               END
,       col2 = CASE
                   WHEN db = 'development' THEN NULL
                   WHEN db = 'staging'      THEN col2
               END
WHERE   db != 'production';In this example:
in the development database, col1 is set to 0 and col2 is set to NULL
in the staging database, col1 is set to 1 and col2 is unchanged (that is, set to what it already was)
in the production database, nothing is changed (the WHERE condition is always FALSE)

How can i construct this query without using CASE statement?

I've a following code. I'm using this script in Hibernet. So, i cannot use CASE there. Because, hibernet doesn't support case in select statement. How can i construct the same thing which will give me the same result without using CASE?
SELECT ofc.FLT_LCL_ORIG_DT
     , ofc.CARR_IATA_CD
     , ofc.FLT_NBR

2 ideas:
1. Inline function to perform the CASE funcionaltity for you
2. Piplelined function to generate the entire dataset
Both will be slower than just using CASE in a query, but we're working around big constraints

Using Case statement instead of IF in formula fields
