DECODE in expression

Hello list,
How do I go about DECODE function in expression?
It's legal only in SQL statement, so validation is fine, but when OWB deploys a script I have error message because DECODE is used in PL/SQL as well. I have solved it temporarly manually changing the script, but this is an error-prone method. What are other solutions except creating user transformation?
TIA,
Alex

I have tried it, but it won't work.
For instance:
case INGRP1.CD
when 1 then 2
else 3
end
Gives the folowing error:
Line 1, Col 1:
PLS-00103: Symbool "CASE" aangetroffen terwijl een van de volgende werd verwacht:
( - + mod not null <an identifier>
<a double-quoted delimited-identifier> <a bind variable> avg
count current exists max min prior sql stddev sum variance
execute forall time timestamp interval date
<a string literal with character set specification>
<a number> <a single-quoted SQL string>
This means that the word CASE cannot be used as first.
Any suggestions? I cannot found any documentation about creating expressions (syntax, functions, examples).
Very sad, because it takes a lot of time to accomplish such a simple thing.

Maurice

Using Decode in Expression Builder...

Hi everybody,
I want to use the DECODE function of SQL in an Expression Builder....
Of course this function does not exist in any of the transformation categories(arithmetic,character,e.t.c.) in the expression builder.
I have read in the OWB on-line help that in the Expression Builder there should be an 'Others' drop - down list in order to select any of the available SQL clauses - one of them is 'decode'...
The problem is that this drop - down list in the Expression Builder is disabled.....
How can I use this function anyway..????
Instead of using ... in the Expression Builder...
decode(<column_name>,'1','val_one','2','val_two') what can I use to do the same....???
As regards the problem that the drop-down list is disabled , what may be the cause..???
I use Microsoft XP machine , Oracle 10g (v.10.2) and OWB v.10.1.0.4
The documentation says....
"This allows you to deploy the DECODE functionality in all operating modes (setbased, rowbased, etc.) and transparently across Oracle database releases (8.1, 9.0 and 9.2)."
The above means that the cause is the incompatibility..????
Thanks , a lot
Simon

I am using OWB 9.2.0.8 and I can't reproduce the problem you are having with 10.1, but did you try just typing it into the expression?
Or, better yet, use CASE. The syntax is easier to read. I think OWB translates DECODEs to CASE when the SQL is generated.
(Case <column_name>
When '1' Then 'val_one'
When '2' Then 'val_two'
End)

OWB Error for using Decode in Expression

Debug code deployment messages:
LINE 4558 ,COLUMN 71:
PLS-00204: function or pseudo-column 'DECODE' may be used inside a SQL statement only
LINE 4558 ,COLUMN 17:
PL/SQL: Statement ignored
End debug code deployment messages
DBG1012: Debug deployment errors, can't run debug code.

What i have experience is that if you use Decode inside the expression the OWB cannot validate it .
But it will execute perfect.
Use Case statement so that you can validate it and debug then

Decode limited expression?

Hello Guru's,
I have a table t with 13,000 records.
I am attempting to update records in a column, example:
update t
set col1=(decode(col1,'AA','Antiseptic',
,'BB,'Builder',
,'CC','Contractor'))
commit;
The problem is that I have to update around 300 types of AA, BB at once- needless to say DECODE has it's limits. So, not being a very good developer I decided to break the decode updates to every 40 or so types- this did not work.
It would update only on the first set of decoding I did- around 40 enteries, then the next update I made did not work.
Is there anyway I can update these all 300 types in one execution? Or is there another way to update the records with another expression other than decode that will allow 300 plus type updates?
I hope this is not confusing.

While my strong preference would be to use a dummy table approach as Eric and 519668 suggested, if y ou really want to go the DECODE route, and I still prefer the dummy table, then your update statements need to be like:
UPDATE t
SET col = DECODE(col, 'AA', 'Antiseptic',
                      'BB', 'Builder',
                      'CC', 'Contractor')
WHERE col in ('AA', 'BB','CC');
UPDATE t
SET col = DECODE(col, 'DD', 'Developer',
                      'EE', 'Engineer',
                      'FF', 'Foo')
WHERE col in ('DD', 'EE','FF');But really, put the values in a table and use that table to update as suggested.

I cant put .xesc in decoder (microsoft Expression Encoder) or windows movie player

tell me how we can decode an .xesc after renaming it cause if I double click it it plays but when I drag into wmm it says it not compatable please send a solution back please

I've had pretty good luck with Flip4Mac. Here's a blurb about what it will translate (thru Quicktime):
Advanced Systems Format (ASF), Advanced Stream Redirector (ASX) and Audio Video Interleaved (AVI). The plug-in can also handle Windows Media Video (WMV) containers, which have the same roots as ASF. The Microsoft's audio container, Windows Media Audio (WMA) is also supported by this plug-in.
One quick question....you downloaded it, but did you install it? Sorry if that's a dumb question for you, but, for some, it's a reasonable concern.
All that being said, if you're asf isn't playing, possibly it doesn't conform to a standard compatible with F4M. Occasionally I will run across a file that says it's a wmv, but hiding underneath is an unsupported codec, which renders it unplayable on a Mac with F4M, or anything else.
Sometimes VLC will play content that nothing else will.

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.

Decode vs. Case in OWB Transformation

Hello all,
I am trying to count or sum all of Reasons where the value is Test. Here is the code which I would like to covert into OWB transformations:
sum(decode( REASON ,'Test',1,0) )
Step 1:
I tried to use Decode in expression
(decode( REASON ,'Test',1,0) ) and it gives me following error:
Line 1, Col 1:
PLS-00204: function or pseudo-column 'DECODE' may be used inside a SQL statement only
Line 0, Col 1:
PL/SQL: Statement ignored
It seems OWB does not recognize Decode. How should I solve the problem? Should i try using Case to substitute the above decode code ? like:
Case
when Reason='Test'
then 'Test'
End
Am I doing it right?
and following this I can use aggregator to Sum(test) for counting/summing all tests. Is there anyway I can use this code: sum(decode( REASON ,'Test',1,0) ) in one transformation? Please let me know.
Thanks,
K

OWB provides case statement in place of decode. OWB does not recognize decode statements(till what i know, and tried out)
Why dont you first use a filter (on reason='test') and then use an aggregrator transformation, You can put input as the column reason from the filter and make a new column in the output group for summing it.
Hope i have solved your doubts....

Report Performance - Summary Fields Setting

I have a report data model with 3 groupings. Summary fields are needed for each group. There are 2 approaches for me to have the summary values :
1. i can set the data source of each summary field to be the corresponding column of my based Q_1 selection statement, and then set the "Reset At" for different data groups.
2. On the other hand, i can set the data source to be the summary field of the inner data group.
Could anyone tell me which method can give me a better performance? I want the report to run faster.

Puvan,
I figured out the problem myself. It is not a version issue.
I was using a sum function on a decode expression in the sql command. The % total was applied on that sum expression. Every time I was reopening the report the sum expression was getting created in a new group.
When I gave an alias for the sum(decode(xyz)) expression it is working fine now.
I would still consider that as an issue with Reports Developer.
FYI...

Summary fields in the JSP report

I created a JSP report using Oracle 9i Reports Developer using report wizard. It has a %Total field on one of the columns.
It is running good for the first time. But when I am closing and reopening the report the Summary column is showing a null value in the source column. And it would not run the report.

I am unable to run this query

Can i use logical operator in decode in expression like following ..
SELECT 'FY'||DECODE( TO_CHAR(TO_DATE('1/30/2008','MM/DD/YYYY'),'MON'),'JAN',
     DECODE('(TO_DATE(''1/30/2008'',''MM/DD/YYYY'') >= TO_DATE(''1/30/2008'',''MM/DD/YYYY''))','TRUE',

) FROM dual
unable to get the result in true condition
it should print FY2008 but printing FY2007 why?
can anyone help me on this ?

Adobe Barcoded Forms and LiveCycle Licensing

If you add a Paper Forms Barcode object to a fill-and-print PDF form using either Designer or Acrobat and the value of the barcode will change while opened within the free Adobe Reader then the PDF form you are distributing needs to be licensed with an Adobe® LiveCycle® Barcoded Forms ES license. I need to create a dynam ic barcode that users can change using Adobe Reader and print the form with barcode intact. It's for use in a pre-K school. Usage will be limited to 200 students per year.(Creating 200 forms that teacher's will fill out). I believe this is my solution, but pricing may be way too high. What are my options and have I been correct so far? There is no server, only a WORKGROUP environment. Thanks.
Tom: Ok, so from the Adobe side, yes, LiveCycle Forms is the only tool that can achieve this. It used to be called Barcoded Forms ES, now it is just Forms ES2. Unfortunately it is a server only product so you would need a server.
Tom: List price is around 85k, so I think it might be a bit more than you guys need unfortunately.
Tom: We don't really have a basic barcoded forms piece for smaller initiatives, unfortunately.
Visitor: Yikes!
Visitor: What are my options?
Tom: Do you absolutely need barcodes? Or could you do online fill in and submit?
Visitor: If I purchase Acrobat Standard(I created the form is Professional) for 5-10 people, that should do the trick as long as the Adobe READER user doesn't change the barcode information, correct?
Tom: Honestly, I'm not sure. Acrobat isn't something I am an expert on.
Tom: You could try Adobe Formscentral as well as using Acrobat.
Tom: Otherwise you'd have to try the Acrobat forums or user community as I don't have a lot of info about it.
Visitor: The forms are printed by the teacher/evaluator and hand-written to be scanned when completed(End of month, etc). A barcode decoder(Kofax Express) will read the barcode and rename the file according to the barcode data.
Tom: Hm, I think the Acrobat forums is your best bet, then.

Thanks for the great suggestion!
Can a Pre-K school receive an educational
institution discount on Acrobat pricing?

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

Decode Attachment in OutLook Express .dbx with MimeUtility?

Hi boys,
I want to extract an attachment (encoded in base64 format) from outlook express .dbx file.
I construct 2 classes :
- the first extract from dbx file the attachment data and write it to disk.
- the second read from disk and decode with MimeUtility class (JavaMail).
The result is that the final file decoded is 600 byte less the original.
sigh!.
Can Anyone help me?
Thanks Emanuele

Does the condition specified in the function 'DECODE' allow 'BETWEEN' expression?

Does the condition specified in the function 'DECODE' allow 'BETWEEN' expression?

As a completely different approach, in 8i SQL and 9i PL/SQL we can use the CASE function. This delivers decode functionality, but allows us to use conditions e.g.
SELECT CASE WHEN col BETWEEN 1 and 9 THEN 'one' ELSE 'two' END FROM my_table;I love DECODE and wouldn't use anything else for straight value substitutions but CASE does have the advantage of clarity when it comes to maths, etc. Also I believe DECODE is not ANSI compliant. In which case (ho ho!) I suspect it will probably be deprecated, as Oracle seems to be moving towards ANSI SQL compliance, as part of its open standards drive.
Cheers, APC
