Using 'DECODE' instead of 'CASE' in select

Hi,
I am using CASE statements in my Select clause using 9i.
SELECT
                 CASE
                       WHEN S.cmpy_num = S.cpty_borg_num THEN
                       ''OURS''
                       ELSE
                       ''THEIRS''
                       END AS SDIOwner,
                       S.active_flag,
from SDI sI wud like to try this in 8I but 8i doesnt support CASE statements
in Select clauses.
It was recommended to use Decode in place of CASE in 8I
How can i write the decode statement for the above CASE statement in 9I

GOT IT RUNNIG.THANKS A LOT JAMES...
I AM TESTING SYSTEMS ON 9I AND 8I...

Problem using Decode/Case

I have one table which stores candidates' response. The structure is like this
(Seatno, Questionnumber, Answer).
And I have another table Master as (Questionnumber, Answer)
Now I want to calculate marks by comparing Candidate's response with Master.
I tried to use decode and case. But was not successful.
My query with decode was ...
select c1.candidatesrno, sum(decode(c1.answer,(c1.answer=m1.answer),1,0))
from candidate c1,master q1
where c1.question=m1.question
group by c1.candidatesrno
And query with CASE was...
select c1.candidatesrno,
case when (c1.answer=m1.answer) then 1 else 0
end resultset
from candidate c1,master m1
where c1.questionnumber=m1.questionnumber
group by c1.candidatesrno
Can anybody help ?

I want to compare candidate's response with master
table.
Now for each question of Candidate, if its answer
matches with answer in Master table I have to give 1
marks...if it does not match I have to give 0
marks...like this there are two-three conditions...
Something like this ?

Why we use Tables statement in case of using SELECT-OPTIONS:

hi all,
Why we use Tables statement in case of using the following coding in an ABAP program ...
tables: vbak.
SELECT-OPTIONS: s1 for vbak-vbeln.
here if we dont provide the tables statement why it does not work ????
pls answwer ....???

Hi
This statement is not allowed in classes and declares a data object table_wa as a table work area whose data type is adopted from the identically named structured data type table_wa from the ABAP Dictionary. table_wa must be defined as a flat structure in the ABAP Dictionary. You can specify database tables or Views for table_wa.
Work table areas declared with TABLES are interface work areas and should only be declared in the global declaration section of a program for the following purpose:
reward if usefull
The statement TABLES is required for exchanging data between screen fields that were defined in a program screen when transferring from the ABAP Dictionary and the ABAP program. For the screen event PBO, the content of the table work area is transferred to identically named screen fields; for PAI, the system adopts the data from identically named screen fields.
In executable programs, flat table work areas can be used for adopting data that were provided for the event GET table_wa from a linked logical database. TABLES is synonymous with the statement NODES for this purpose.
Work table areas declared with TABLES behave like the data declared with the addition COMMON PART, meaning the data are used by the programs of a program group.
Table work areas declared with TABLES can be declared in subroutines and
function modules. However, this is not recommended. A table work area declared in a procedure is not local but belongs to the context of a framework program. The table work area can be viewed starting from the declaration in the framework program and lives as long as the framework program. In contrast to normal program-global data, the content of the table work areas declared in subroutines and function modules is stored temporarily when these subroutines and function modules are called. Value assignments that were made during runtime of the procedure are preserved until the procedure is completed. When exiting the procedure, the table work areas are filled with the contents that they contained when the procedure was called. Table work areas declared in procedures behave like global data to which the statement LOCAL is applied in the procedure.
The form TABLES * is obsolete.

Problem using CASE within SELECT in a standard REPORT region

I'm trying to do a CASE-oriented SELECT within a standard REPORT region and the parser is rejecting the SQL statement.
The code I'm using is the following:
SELECT
CASE
WHEN INSTR(citation, '@') > 0 THEN
SUBSTR(citation, 1, INSTR(citation, '@')-1)
|| ':'
|| SUBSTR(citation, INSTR(citation, '@')+1,
LENGTH(citation) - INSTR(citation, '@'))
ELSE citation
END
FROM citation
WHERE obj_table_cd = 'FI'
AND obj_id = :P41_FIND_ID
ORDER BY CITATION
The parser says the (case .... ) is invalid, use column alias. The query works correctly when using SQL_Developer and SQL*PLUS.
My intention is to replace an '@' with ':' within the citation text. The standard citation format should have a colon, but this causes problems with AppExpress, hence the substitution situation.
Any insights on this or on another way to achieve the purpose?
Thanks,
George

George,
You should give a column alias after the END of the case statement:
SELECT
CASE
WHEN INSTR(citation, '@') > 0 THEN
SUBSTR(citation, 1, INSTR(citation, '@')-1)
|| ':'
|| SUBSTR(citation, INSTR(citation, '@')+1,
LENGTH(citation) - INSTR(citation, '@'))
ELSE citation
END citation_col
FROM citation
WHERE obj_table_cd = 'FI'
AND obj_id = :P41_FIND_ID
ORDER BY CITATIONSam

Using decode function without negative values

Hi friends
I am using oracle 11g
I have at doubt regarding the following.
create table Device(Did char(20),Dname char(20),Datetime char(40),Val char(20));
insert into Device values('1','ABC','06/13/2012 18:00','400');
insert into Device values('1','abc','06/13/2012 18:05','600');
insert into Device values('1','abc','06/13/2012 18:55','600');
insert into Device values('1','abc','06/13/2012 19:00','-32768');
insert into Device values('1','abc','06/13/2012 19:05','800');
insert into Device values('1','abc','06/13/2012 19:10','600');
insert into Device values('1','abc','06/13/2012 19:15','900');
insert into Device values('1','abc','06/13/2012 19:55','1100');
insert into Device values('1','abc','06/13/2012 20:00','-32768');
insert into Device values('1','abc','06/13/2012 20:05','-32768');
Like this I am inserting data into table for every 5 minutes Here i need the result like
output:
Dname 18:00 19:00 20:00
abc 400 -32768 -32768
to retrieve this result i am using decode function
SELECT Dname,
MAX(DECODE ( rn , 1,val )) h1,
MAX(DECODE ( rn , 2, val )) h2,
FROM
(SELECT Dname,Datetime,row_number() OVER
(partition by Dname order by datetime asc) rn FROM Device
where substr(datetime,15,2)='00' group by Dname.
According to above data expected result is
Dname 18:00 19:00 20:00
abc 400 600(or)800 1100
This means I dont want to display negative values instead of that values i want to show previous or next value.

Are you looking for something like this?
select * from
select dname,
       datetime,
       val,
       lag(val) over (partition by upper(dname) order by datetime) prev_val,
       lead(val) over (partition by upper(dname) order by datetime) next_val,
       case when nvl(val,0)<0 and lag(val) over (partition by upper(dname) order by datetime) >0 then
         lag(val) over (partition by upper(dname) order by datetime)
       else
         lead(val) over (partition by upper(dname) order by datetime)
       end gt0_val
from device
order by datetime
where substr(datetime,15,2)='00';Please take a look at the result_column gt0_val.

CASE in SELECT statement

Hello,
in Oracle8 I've the following problem:
The statement

works fine but defining the same statement as a cursor in a PL/SQL Procedure, I got a
Error: PLS-00103: Encountered the symbol "CASE" when expecting one of the following:

The same procedure can be compiled in Oracle9i without errors.
Does anybody know if there are any restrictions using CASE statements in a PL/SQL CURSOR in Oracle8?

Hi,
I am encountering the same problem.
Can u suggest the decode statement used instead of case
for this select clause which uses the CASE statement ?
SELECT
                       CASE
                       WHEN S.cmpy_num = S.cpty_borg_num THEN

How to use decode on the value part ?

i have a query
select
     col1, col2, col3
from
     tab1, tab2
where
     cond1= 'parameter1'
I need to modify this query to use a decode function instead of this parameter1.
something like
select
     col1, col2, col3
from
     tab1, tab2
where
     cond1= decode(parameter1, 'x','val1','val2')
How can i use such a decode function on the value part ?
IF i try this, it gives me no data found error....
The following is also not working..IS there a way to do such cases ?
select
     col1, col2, col3
from
     tab1, tab2
where
     cond1= ( select decode(parameter1, 'x','val1','val2') from dual )

Of course it works...

I could create a report which has selected objects and defined where condition from the above query. I have also created a variable for 'when' & 'then' condition but stuck at else part which contains 'DECODE' function.
Please suggestions how to write the same at the report or designer level.
Thanks,
Rameez Shaikh

Hi Rameez,
Looking at the query you can create the object directly in the universe, either create two objects one for inner decode and use it in outer case logic. In report it is nothing but nested if logic. For eg. If(a=b;1;(if(a=c;2;3))
Thanks

Use of insert in case

Hi,
Is it possible to use insert statement in CASE.
For example as follows:
let create a table as
create table DECOMPENSATED_BALANCE_TMP (ENDING_ENTERED_BALANCE_DR number, ENDING_ENTERED_BALANCE_CR number);
select
CASE
WHEN (PERIOD_NET_DR+BEGIN_BALANCE_DR-PERIOD_NET_CR-BEGIN_BALANCE_CR) total > 0
THEN
INSERT INTO XXGL_DECOMPENSATED_BALANCE_TMP (ENDING_ENTERED_BALANCE_DR) values (total)
WHEN (PERIOD_NET_DR+BEGIN_BALANCE_DR-PERIOD_NET_CR-BEGIN_BALANCE_CR) <= 0
THEN
INSERT INTO XXGL_DECOMPENSATED_BALANCE_TMP (ENDING_ENTERED_BALANCE_CR) values (total)
else
NULL
end
from gl_balances
where code_combination_id=109940 and currency_code='GBP';
Any answers will be highly appreciated ....
Thanks,
zaheer

I don't think that a conditional insert is really needed in this case. THe only part where the insert differse is the else part of your case statment where no insert should be done. THis can be made into a where clause.
An easy way would be to use a simple INSERT + SELECT statement. Where the value for the dr and cr columns are created by a case or a decode statement.
untested example
insert into XXGL_DECOMPENSATED_BALANCE_TMP
(ENDING_ENTERED_BALANCE_DR, ENDING_ENTERED_BALANCE_CR)
select case WHEN (PERIOD_NET_DR+BEGIN_BALANCE_DR-PERIOD_NET_CR-BEGIN_BALANCE_CR) > 0 then total
          else null
          end as DR
         ,case WHEN (PERIOD_NET_DR+BEGIN_BALANCE_DR-PERIOD_NET_CR-BEGIN_BALANCE_CR) <= 0 then total
          else null
          end as CR
from gl_balances
where code_combination_id=109940
and currency_code='GBP'
and (PERIOD_NET_DR+BEGIN_BALANCE_DR-PERIOD_NET_CR-BEGIN_BALANCE_CR) is not null -- else part
;The good thing is you could run this insert statement for several code_combination_ids directly in SQL without any pL-loop.
Just noticed that leonard aready posted almost the same solution.

How to use DECODE function in Exspression?

Hi,
Can we use DECODE in Expression?
I'm trying to use DECODE function but there is an error during the validation. But when i validate the mapping, it is successfully compiled but it is failed during deployment.
But if I use CASE instead of DECODE, it works fine.
Can we use DECODE in OWB???
Thanks
Raj

Hi,
In OWB 10gR2, if your are using only one DECODE in an expression, it's working. The package will compile when deploying the mapping. OWB will replace the DECODE by a CASE.
But when you are using nested decode in an expression ( for example : decode(col1, 1, 'M', decode(col2, 'Madame', 'Mme', null)) ) only the first one is replaced by a case at deployment.
In ROW_BASED mode, text of the expression is used outside of an sql statement and deployment will fails with "PLS-00204: function or pseudo-column 'DECODE' may be used inside a SQL statement only."
If operating mode for the mapping is set to SET_BASED, it's working because the expression is used in an sql statement.
I have logged a SR in metalink for this issue and a bug is opened (bug 5414112).
But I agree with you, it's better to use case statement.

How to Use Decode for manipulating time

How can i use Decode function to manipulate time...
Example
suppose ive employee and his time in...i want to display status field by using decode,which reflects if that employee came after 09:15:00 the status='L' else this will print 'P'
i tried this
SELECT pin_code,DECODE( to_char(ACCESS_TIME,'HH24:MI:SS'>'09:15:00','l','P'))STATUS
FROM ATTENDANCE_REG
this query hasn't work...
waiting for reply
Regards
Danish Hayder

SQL> select case when to_number(to_char(sysdate,'sssss')) > 33300 then 'L'
2 else 'P' end status

Can I use decode( decode...)...)

Hi,
Can I use decode function inside decode function.
It seem doesn't work. Please help
decode(lv.RANK||' / '||
decode('('||lv.ONE_YR_PCT||'%)', '(%)','N/A','('||lv.ONE_YR_PCT||'%)'),
'0 / (0%)','N/A', lv.RANK )
Thanks

I'm not quite sure it's the result you intended but your nested decode statement does run ...
SQL> CREATE TABLE lv (rank number, one_yr_pct number)
2 /
Table created.
SQL> insert into lv values (1, 1)
2 /
1 row created.
SQL> insert into lv values (2,2)
2 /
1 row created.
SQL> insert into lv values (0,0)
2 /
1 row created.
SQL> select decode(lv.RANK||' / '||
2 decode('('||lv.ONE_YR_PCT||'%)', '(%)','N/A','('||lv.ONE_YR_PCT||'%)'),
3 '0 / (0%)','N/A', lv.RANK )
4 from lv
5 /

Alternatively, as CD suggests, you may find it easier to express your logic using CASE.

Basic query using DECODE not working as expected.

Version:11.2.0.3
Platform: RHEL 5.8
I am trying to use DECODE function.
In the below example, If the search encounters the string "Enterprise" , then the decode should
return 'Enterprise' . But it doesn't seem to work.
I thought some hidden character was causing the issue, so, I used TRIM. But no luck.
SQL> create table t (banner varchar2(80));
Table created.
SQL> insert into t values ('Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production');
1 row created.
SQL> commit;
Commit complete.
SQL> select * from t;
BANNER
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
SQL> select * from t where banner like '%Database%';
BANNER
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
-- Trying to use decode. If the search encounters the string "Enterprise" , then return 'Enterprise'
-- Although the string "Enterprise" is present , decode doesn't seem to work.
-- I tried using trim , upper . But no luck.
SQL> select 'EDITION', decode(banner,'%Enterprise%','Enterprise','Standard') Edition from t where banner like '%Database%';
'EDITIO EDITION
EDITION Standard
SQL> select 'EDITION', decode(trim(banner), '%Enterprise%','Enterprise','Standard') Edition from t where trim(banner) like '%Database%';
'EDITIO EDITION
EDITION Standard
SQL> select 'EDITION', decode(upper(trim(banner)), '%ENTERPRISE%','Enterprise','Standard') Edition from t where upper(trim(banner)) like '%DATABASE%';
'EDITIO EDITION
EDITION Standard
SQL>
Just don't understand why decode can't see the string "Enterprise"
BTW . Where is the preview button ?

It (a portion string matching) ain't work in DECODE, for this CASE has a advantage of using over it.
Like
with t
as
(select 'Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production' banner from dual)
select 'EDITION',
case when banner like '%Enterprise%' then 'Enterprise' else 'Standard' end edition
from t
'EDITIO EDITION
EDITION Enterprise

Using 'DECODE' instead of 'CASE' in select
