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

Can any one pls help me using of Case Condition keyword instead of Decode in the above query ??? iam not able to convert above query for group by and order by..
Actually i need to do group by the aggragate values which i got the values from the fields of BILLABLE_YN,BILLABLE_TO,DETAIL_CLASS, COST_TYPE, BILL_RATE.
where as in oracle i can run above query using decode keyword where as in sqlserver iam not able to use BILLABLE_YN field alias of above query in group by .
i tried like by using following way but it is wrong because here iam not using aggragate values of fields in group by funtion please help me in converting query in sqlserver. GROUP BY (case BILLABLE_YN when 1 then 'Billable' when 0 then 'Non-Billable' else
'Non-Billable' End BILLABLE_YN + ',' + BILLABLE_TO + ',' + DETAIL_CLASS + ',' + COST_TYPE + ',' + BILL_RATE)

How to use index, when query has decode/case

Any help will be appreciated

You can rewrite your where clause to not use decode or case statements e.g. this:
AND LkupPartyUsage.LOOKUP_CODE = DECODE( ThirdPartyTaxProfileEO.CUSTOMER_FLAG
                            , 'Y', DECODE( ThirdPartyTaxProfileEO.SUPPLIER_FLAG, 'Y', 'SC', 'C' )
                                 , DECODE( ThirdPartyTaxProfileEO.SUPPLIER_FLAG, 'Y', 'S', NULL ) )
                                 )can be rewritten to this:
and (
      ( ThirdPartyTaxProfileEO.CUSTOMER_FLAG = 'Y' AND
          ((ThirdPartyTaxProfileEO.SUPPLIER_FLAG = 'Y' AND LkupPartyUsage.LOOKUP_CODE = 'SC') or
            ThirdPartyTaxProfileEO.SUPPLIER_FLAG != 'Y' AND LkupPartyUsage.LOOKUP_CODE = 'C')) or
      ( ThirdPartyTaxProfileEO.CUSTOMER_FLAG != 'Y' AND
          ((ThirdPartyTaxProfileEO.SUPPLIER_FLAG = 'Y' AND LkupPartyUsage.LOOKUP_CODE = 'S') or
            ThirdPartyTaxProfileEO.SUPPLIER_FLAG != 'Y' AND LkupPartyUsage.LOOKUP_CODE is null))
    )It's not as sussinct, but it avoids the use of functions that could be preventing the optimiser from using an index.

How to use decode function in oracle apex 3.2.1

Hey just on this particular point, there's a handy PL/SQL method for escaping quotation characters which may reduce the complexity of the string.
For example, if I had a string:
I can't understand why quoting my 'quote' characters never seems to "work"!and I wanted to pass that into a variable, I could do this:
vc_foo:= 'I can''t understand why my ''quote'' characters never seems to "work"!';or I could use the q function, whereby you enclose your string within a quote delimiter of your choice, like so:
vc_foo:= q'^I can't understand why quoting my 'quote' characters never seems to "work"!^';
note: I used the caret (^) character by convention but any valid character will do
...all of which leaves your original string more or less unadulterated.
I find this particularly useful for generating dynamic SQL and dynamic PL/SQL, as it leave the query looking a tad more readable, although if you are chaining together multiple strings with double-pipes, it can make it a little muddier. I find it particularly useful if I'm going to deal with string data from, for example, a field with Irish-derived surnames such as "O'Reilly"...
Give it a go!

How to use decode to calculate sum for different date range

I'm stuck with decode() function:
I have a table like this:
(project_id, approve_date, value, builder_code)
I want to write a SQL query to get sum of values for different month of the approve_date, and group by builder_code)
The result is like this:
builder_code Sum(value)_Sep-03 Sum(value)_Oct-03 Sum(value)_Nov03
1001 1,299 1,322 990
1002 3,332 1,222 333
I tried to use decode for this question but could not get the answer.
Thanks a lot

I don't think you need a DECODE() here. I'd do something like this-
create table builder (
    project_id number,
    approve_date date,
    value        number,
    builder_code number
insert into builder values( 1, to_date('09-01-2003', 'MM-DD-YYYY'), 100, 990 )
insert into builder values( 2, to_date('09-03-2003', 'MM-DD-YYYY'), 150, 990 )
insert into builder values( 3, to_date('09-05-2003', 'MM-DD-YYYY'), 250, 990 )
insert into builder values( 3, to_date('09-05-2003', 'MM-DD-YYYY'), 250, 333)
SELECT sept.builder_code, sept.sept_sum, oct.oct_sum
FROM (SELECT builder_code, sum(value) sept_sum
        FROM builder
       WHERE approve_date >= to_date('09-01-2003','MM-DD-YYYY')
         AND approve_date < to_date('10-01-2003','MM-DD-YYYY')
       GROUP BY builder_code) sept,
     (SELECT builder_code, sum(value) oct_sum
        FROM builder
       WHERE approve_date >= to_date('10-01-2003','MM-DD-YYYY')
         AND approve_date < to_date('11-01-2003','MM-DD-YYYY')
       GROUP BY builder_code) oct
WHERE oct.builder_code(+) = sept.builder_code
BUILDER_CODE   SEPT_SUM    OCT_SUM
         333        250
         990        500Justin

GROUP BY b.g,b.s

Very strange.
Find out if there are alterations to your SQL*PLUS envirionment. Warren mentioned user/database wierdness; the ALTER SCHEMA and other commands can affect privilges and what objects you can see. Sometimes these commands are buried in LOGIN.SQL and GLOGIN.SQL files (for SQL*PLUS), and more hard to find they can call files buried on a network somewhere.
Try the query without the DECODE() and see what's in the table without trying to modify the values in both envirionments.

appreciate your help in this rgds.
thanks/kumar

Dear Sir / Madam,
Thanks for your understanding.
Right now I am facing a unique problem.
I am using decode function in a select statement. The columns are dynamic some columns are of type number and some are varchar datatypes. I want to apply decode function for every column irrespective of datatype.
What i am finding difficult is if the column is a number datatype , the decode funciton is working good but if the column datatype is varchar or char datatype then i am getting ..
here's the decode function..
decode (CHAI.EVNDRIVE,
-800000000000000,'.A',
-700000000000000, '.B',
-600000000000000 ,'.C',
-500000000000000 , '.D',
-400000000000000 , '.E',
-300000000000000 , '.F',
-200000000000000, '.G',
-100000000000000 , '.H',
-1000000000, '.R' ,CHAI.EVNDRIVE ) EVNDRIVE
report error:
ORA-01722: invalid number
pls let me know how to over come this kind of scenario.
is their a way to find whether the column datatype is number or char , so that i can check the column datatype before the decode funciton is applied ..
thanks ..

How to use decode concept in htp.p?

Hi All,
How to use decode function in htp.p syntax?
Thanks,
Anoo..

Hi,
Could you please give more details on what you like to achieve? Decode function works only in sql query.
You can first do sql query, and then do htp.p.
Or you can use PL/SQL IF or CASE statements.
You can also create custom decode function if you need.

Insert while using Decode Statement

Hi,
I have a unique problem(I think so). Is it possibe to insert into a table while selecting from another table using DECODE function. I am giving the select statement below. When I run this statement it says that missing expression. I could not find out the mistake. Is this query right or any changes to be made. Moreover I would like to know whether it is the right way of doing.
The SQL Statement is as follows.
SQL> select decode(EV,'E',(INSERT INTO assets1 VALUES
(31,NULL,NULL))) from assets;
Thanking in advance for timely help.
Guru Prasad.

Hi,
U Cannot do that ... B'cos u cannot have Insert Inside a Select.
What you can do is... Right a Small Pl/SQL Block which will do that for you.

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 ?
