Decode in query

I have tried to use this query in an application and it never runs the 'Yes' part. I ran it in sqldeveloper and I get the same result regardless of what I put in the variable. I can't see the error in it. Help?
select * from SF_CASE where CASE_NUMBER not in decode(:P57_Used_Cases, 'Yes',
'(Select Case_Number from FAQ_CASE_JUNC)',
'(Select Case_Number from FAQ_CASE_JUNC where Case_Number = ''1'')' )

Decode statement doest not take sql queries as
parameter. Actually, it takes.
When it is a scalar subquery:
SQL> with t as (select level from dual connect by level<=4)
2 --
3 select * from dual where 1 not in decode('Yes','Yes',(select * from t where rownum=1),2)
4 /
DUMMY
SQL>
SQL> with t as (select level from dual connect by level<=4)

Decode affecting query performance

Hi. We have a system that holds two account numbers, in 8 digit and 12 digit formats. I have a screen with an input box where the user can enter either style account number.
So the select I need to do, must be conditional based on the type used. I've got it working by checking the length of the account number entered:
select column1 from table1
where decode(length(:P1_ACCNUM),12,accountno,accno_8digit) = upper(v('P1_ACCNUM'))
but the performance has gone from instant, to about 3 seconds. In TOAD, the query is unaffected, so maybe it's the subsitution of the variable. I've tried the way coded above, and v('P1_ACCNUM') but there is no difference in Apex.
Does anyone have any ideas on this?
Cheers
Carlton
(NR - Business as Usual.)

Hi George. Initially, the code only supported the 12 digit account number,but you know what users are like! So the original query was coded to say
accountno = :p1_accnum
The decode was necessary because I had to do the comparison on another column. Both columns are indexed.
As I say, putting the length() function (and I also do an UPPER conversion too) in hidden fields and using them has made it perform perfectly again. If I had more time, I wouldn't have coded it like this, but it's an urgent throw away application to perform quick account queries.
Thanks for your response.

Problems with decoding an latin1-encoded url

Hi,
i have a problem with decoding german umlaut-characters from an URL.
I'm using Tomcat 5.5 on a Linux server and one on a windows machine for development. Both webapps have the same configurations.
A servlet decodes the URL-String, parses it and stores the parsed data into a mysql-DB.
For decoding the query-string i'm using org.apache.commons.codec.net.URLCodec.URLCodec.decode .
Here's the code:
String unparsedParameters = request.getQueryString();
URLCodec codec = new URLCodec("ISO-8859-1");
result = codec.decode(unparsedParameters);Here an example for a query-string: http://servername:8080/servlet/Import?Etwas%20wurde%20am%2025.08.2010%2010%3A16%3A50%20*ge%E4ndert*
On the windows machine the word "*geändert*" is decoded correctly. But on the linux server i get "*ge?ndert*". It makes no difference if i write the result into the database or just into a logfile.
Can anyone help?
Thanks in advance.

Problem resolved.
Instead of using the decode-method as described in my fist message now i'm doing the folowing:
fURLDecodigCharset = "ISO8859-1";
byte[] bytes = originalParam.getBytes(fURLDecodigCharset);
byte[] decodeUrl = URLCodec.decodeUrl(bytes);
result = new String (decodeUrl, fURLDecodigCharset);because the method "decode" decodes the string by using the defaultcharset. And that was the problem.
>
The default charset is determined during virtual-machine startup and typically depends upon the locale and charset of the underlying operating system.
>
Thats why i've got different behaviours on different systems.
Thanks

Help speed up a long running query.

I have a connect by query that is taking a long time to run.
The problem seems to lie in it contains a decode on the CONNECT BY
CONNECT BY prior p_mat = DECODE(NVL(p_sa,'M'),'S',p_top,NULL)If i remove this or make it default to p_top rather than checking the value of p_sa its fine.
Any idea how I can achieve the same result of the connect by without the need for the decode?

Deciphering a SAML Message in ColdFusion

I'm working on an SSO solution for a client. At this time I'm able to encode an authentication message and successfully send it to the ADFS server. The ADFS server handles my login and then returns to my site with an HTTP-POST response. In the POST there is an ADFS encoded SAML message I need to decipher. I found a few samples of code but none have worked. This one seemed to have the most promise but...
<cfscript>
// Decode the query string from Base 64
Decoder = CreateObject("Java", "sun.misc.BASE64Decoder").init();
SamlByte = Decoder.decodeBuffer(Form.SAMLResponse);
// Create Byte Array used for the inflation, the CF way
ByteClass = CreateObject("Java", "java.lang.Byte").TYPE;
ByteArray = CreateObject("Java", "java.lang.reflect.Array").NewInstance(ByteClass, 1024);
// Create Byte Streams needed for inflation
ByteIn = CreateObject("Java", "java.io.ByteArrayInputStream").init(SamlByte);
ByteOut = CreateObject("Java", "java.io.ByteArrayOutputStream").init();
// Create Objects needed for inflation
Inflater = CreateObject("Java", "java.util.zip.Inflater").init(true);
InflaterStream = CreateObject("Java", "java.util.zip.InflaterInputStream").init(ByteIn, Inflater);
// Complete the inflation
Count = InflaterStream.read(ByteArray);
while (Count != -1) {
ByteOut.write(ByteArray, 0, Count);
Count = InflaterStream.read(ByteArray);
// Finished with inflation
Inflater.end();
InflaterStream.close();
// Convert SAML request back to a string
SamlString = CreateObject("Java", "java.lang.String").init(ByteOut.toByteArray());
</cfscript>
When the code get to the Count = InflaterStream.read(ByteArray); statement the following error message is returned: oversubscribed dynamic bit lengths tree
My question is does anybody have a snippet of code that is used to successfully decipher an ADFS encoded SAML response?

Whatever version came with MX7. When I run it and go to help
and about, it just shows the version info for cold fusion server.
Not the report builder. I know it is the latest version however as
I also downloaded and installed the latest version from
online.

Problem using DECODE() function with a Query of Queries

I
posted
on my blog about an issue I was having trying to use the PL/SQL
DECODE() function with a Coldfusion Query of Queries. This function
works fine when you query a database for information. However, when
you query another query, it seems that CF doesn't recognize it. I
got errors stating that it found a left parenthesis where it
expected a FROM key word. Here is a simplified version of what I am
trying to do:
quote:

<cfscript>
qOriginal = queryNew("Name,Email,CountryCode",
"VarChar,VarChar,VarChar");
newRow = queryAddRow(qOriginal, 5);
querySetCell(qOriginal, "Name", "Joe", 1);
querySetCell(qOriginal, "Email", "[email protected]", 1);
querySetCell(qOriginal, "CountryCode", "AMER", 1);
querySetCell(qOriginal, "Name", "Sally", 2);
querySetCell(qOriginal, "Email", "[email protected]", 2);
querySetCell(qOriginal, "CountryCode", "AMER", 2);
querySetCell(qOriginal, "Name", "Bob", 3);
querySetCell(qOriginal, "Email", "[email protected]", 3);
querySetCell(qOriginal, "CountryCode", "ASIA", 3);
querySetCell(qOriginal, "Name", "Mary", 4);
querySetCell(qOriginal, "Email", "[email protected]", 4);
querySetCell(qOriginal, "CountryCode", "EURO", 4);
querySetCell(qOriginal, "Name", "John", 5);
querySetCell(qOriginal, "Email", "[email protected]", 5);
querySetCell(qOriginal, "CountryCode", "EURO", 5);
</cfscript>
<cfquery name="qCountries" dbtype="query">
SELECT DISTINCT(CountryCode) AS CountryCode,
DECODE(states, "AMER", "North America & Canada",
"EURO", "Europe & Africa", "ASIA", "Japan &
Asia","") CountryName
FROM qOriginal
ORDER BY CountryCode
</cfquery>
<cfdump var="#qCountries#">

So running this returned the following error:
Query Of Queries syntax error.
Encountered "(. Incorrect Select Statement, Expecting a
'FROM', but encountered '(' instead, A select statement should have
a 'FROM' construct.
Does anybody know why this doesn't work? Is it just not
supported? Please note that I have also tried to use the CASE()
function instead of DECODE() and that resulted in basically the
same error. For now I an looping over my distinct query with a
switch statement and manually loading a new query with the data how
I want it. But it would be a lot cleaner and less code to have the
DECODE() to work. Thx!

DECODE() is an Oracle function, not generic SQL. Q-of-Q is a
very limited subset of SQL and lacks many functions and clauses
available in standard SQL, especially what you may be used to using
in your particular RDBMS.

Well if you want to spool query results to a file the first thing you need to do is write a query that actually works.
Why do you think a query like this is valid?
SELECT 'this, is, my, giant, string, of, columns, with, commas, in, between, each, word'
GROUP BY this, is, my, giant, stringYou only have one column in the result set but you are trying to group by three columns and none of them are even in the result set.
What's up with that?
You can only group by columns that are actually IN the result set.

SQL query, Decode function or Case

Hi,
I am writing a procedure, receiving IN parameter p_user_type_cd
where p_user_type possibles values are = 'STUDENT','STAFF','PROVIDER'
if p_user_type_cd = 'STUDENT' , I would like to select WHERE user_type_cd = 'STUDENT'
if p_user_type_cd = 'ALL' , then I would like to select all records. i.e I like to select 'STUDENT','STAFF','PROVIDER'.
SELECT user_type_cd, page_name_cd, access_mode, home_page
FROM oua_user_page_access
WHERE user_type_cd = p_user_type_cd
ORDER BY user_type_cd,home_page;
Will you pl. modify this query to meet the condition.
Thanks,
Murali

Hi murali,
I got your situation and its easy to write a decode for the following
WHERE user_type_cd = p_user_type_cdWHERE user_type_cd = decode(:p_user_type_cd, 'STUDENT','STUDENT','STAFF','STAFF','PROVIDER','PROVIDER',
p_user_type_cd)
Here you write the above and you will get the data.
Hope this helps you,
Best Wishes,
Kranthi.

Decode statement in Select line of a View Object Query

I attempted to create a view object in expert mode with a customized query.
The query had a decode statement in the select line of the query. The view
object compiled correctly but gave an error when run.
ex: select .... decode(CrpSchools.SCHOOLS_ID,null,CrpCustSchools.SCHOOL_NAME,CrpSchools.SCHOOL_NAME) SCHOOL_VALUE, ...
from ....
where ....
The error was that school_value does not exist in the statement. I got the error when
doing a vo.executeQuery().
When I removed the decode statement everything worked correctly. Does anyone know if
the decode statement cannont be used in the select line of a query in a view object?
Or maybe I was linking the query column (SCHOOLS_ID) up to the view attribute (SCHOOL_VALUE) incorrectly in the
Attribute Mappings tab of the VO wizard?

There should be no problem using a DECODE() statement, provided that you've aliases the column as you have done.
At design time, if you click on the (Test) button, does your query test ok?
Are you by chance applying a custom where clause at runtime?
If so, are you saying:
setWhereClause("yourtable.column_alias = ?";
or are you doing:
setWhereClause("column_alias = ?";
for an expert-mode query, you'll need to use the latter syntax.

Understanding the DECODE statement in an SQL Query......

Hi,
This is my query:
SELECT
DECODE(IT.master_flag,0,'-',ea_submission_date),
DECODE(IT.master_flag,0,'-',ea_approval_date),
DECODE(IT.master_flag,0,'-',ea_date),
DECODE(IT.master_flag,0,'-',ea_comments)
FROM
amendment it,
{CODE}
The master_flag on the AMENDMENT table can be 1,0 or NULL.
I want the above query to output a '-' character in the result set in the 4 columns being selected if the master_flag is either 0 or null.
If it is one 1 however, then display the value of the column. E.G display the data in 'ea_submission_date', 'ea_approval_date', 'ea_date, and 'ea_comments' (if there are values in these columns of course.
Am I right in using the above query?
Thanks!

example
SELECT
DECODE(IT.master_flag,0,'-',null, '-', ea_submission_date) ea_submission_date,
DECODE(IT.master_flag,0,'-',null, '-', ea_approval_date) ea_approval_date,
DECODE(IT.master_flag,0,'-',null, '-', ea_date) ea_date,
DECODE(IT.master_flag,0,'-',null, '-', ea_comments) ea_comments
FROM
amendment it, ...btw, your closing code tag needs to be in lower case too. Please edit your original post and correct that.

Sql query usig round and decode together

can i get one sql quer for returning whole number using round and decode function
eg:
the value 47
if value=47
then
the query should return 50
if the value =44
then
the quer should return 40
pls give me sql query for above example using round and decode function
Edited by: user11368167 on Jul 9, 2009 3:35 AM

A wild guess. If you want the ROUND Function to work only when your column value is 44 or 47 then you could use something like:
SQL> WITH test_tab AS
2       (SELECT 44 col_1
3          FROM DUAL
4        UNION ALL
5        SELECT 15 col_1
6          FROM DUAL
7        UNION ALL
8        SELECT 47 col_1
9          FROM DUAL
10        UNION ALL
11        SELECT 45 col_1
12          FROM DUAL)
13          -- end of test data
14 SELECT col_1,
15         DECODE (col_1,
16                 44, ROUND (col_1, -1),
17                 47, ROUND (col_1, -1),
18                 col_1
19                ) rounded_value
20    FROM test_tab
21 /
     COL_1 ROUNDED_VALUE
        44            40
        15            15
        47            50
        45            45
4 rows selected.
SQL> CASE Statement can be used as well instead of DECODE.
Good Luck,

Query of Queries decode

I have a main query that does a decode on a field so that it
sorts starting with KG then 01,02,03,04,05
When I then pull the QofQ it spits back the results as
01,02,03,04,05,KG. Is there a way around that?

> order by grade
The QoQ is ordering the values correctly. If you don't want
the records sorted by grade, you'll need to add a column to your
main query containing the desired sort order. Then use that column
in your QoQ
select grade
from assessmentData
order by SortOrderColumn

Decode a blob field with a C script in a select query

HI
I have a coded field in a table which has been populated using 3rd party software. I need to decode this field so that i could rub a few reports. I have a C script that can decode this field but do not know how to call it up from a select statement.
Is there any way of decoding this by calling up the C script in a select query.
Thanks.

can you duplicate this code into a PL/SQL function?
Or else, you might try configuring your external procedures setup and call this routine (if it was available as a shared library or a DLL).
