Decode function - using comparison operators

Can I use comparison operators in a decode function such as below:
select tasknum, title, esthrs, assigndate,
decode(assigndate, < '04-OCT-04', '--') accum_hrs
from assignment
thanks.

Using comparison operators to solve several different mathematical expressions is not clear

Though I found LabVIEW very interesting , still some of its basic fundamentals are not clear, like using comparison operators (>,<,..) for solving different
mathematical expressions. Please give example showing how to use such operators in advanced mathematical problems.

You need to be more specific. A comparison operation IS like a logical IF statement and the result is either TRUE or FALSE.
What do you mean by a "mathematical expression"? What do you mean by "different"? Can you give an illustrative example?
If two alternative mathematical expressions should depend on the comparison, wire the comparison output to a case structure and place the two different expressions in their own case, for example.

Problem while using Comparison Operator 'CA' in select queries

Hi ,
I have written select query like this.
   SELECT * FROM rsdodso INTO TABLE gt_rsdodso
                             WHERE odsobject CA s_obj-low.
then I am getting error 'CA is not a valid comparison operator'.
Would you please suggest me how to use Comparison operators.

Hi,
   Use 'IN' and not CA. You cannot use CA in where clause. Write CA in if .. endif.
   SELECT * FROM rsdodso INTO TABLE gt_rsdodso
   WHERE odsobject IN s_obj.
if gt_rsdodso-ODSOBJECT CA '0D_FC_D01'.
endif.

Correct my Decode Function

Hi,
I created a table and inserted some records into the table.
I am trying to find the output using decode function using the below query.

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.

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

How to use a decode function

I want to use the following with decode, recently started on BODS.
Can you please provide the steps to use decode function
in source tabke fieldname is ordid and in target fieldname is Orderid
decode(Order_ID = 1709,lpad(Order_ID,7,'700'),Order_ID)
thank you very much for the helpful i

1) In the mapping tab of target column, click on Functions, select Miscellaneous Functions category, you can find decode function in it. Lpad can be found in String functions category.
OR
2) You can directly script this or paste this code at the mapping tab. In this case, remove the Order_ID from the script wherever used, drag and drop this column from the input schema of Query transform to avoid the syntax error.

Suneer

Use of DECODE function in Discoverer 3.1

Hi all,
Is there any better way of using DECODE in Discoverer 3.1, i dont want to use that function in my Discoverer User edition or Admin ed.
Many of my queries use the DECODE function.
Your help is greatly appreciated.

If you created an instance of your time class that you called myTime
var myTime:Time = new Time(15,15,0);
and later you wanted another instance with the same time you could write
var myTime2:Time = myTime.clone()
It is just there for convienience and doesn't have anything much to do with MVC

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.

Using mysql decode function in Java

Hi everybody,
mysql documentation says:
DECODE(crypt_str,pass_str) -->
Decrypts the encrypted string crypt_str using pass_str as the password. crypt_str should be a string returned from ENCODE().
I used the above function in a Python script and had no problem, but have difficulty using the same thing in my Java code.
I receive runtime error when tried decode() in my Java code in executeQuery("s");. As far as I know the decode() function should be compiled, I can't run the decode() in the mysql command tool and receive a response (as I compiled and ran it in my Python script).
Has anybody ever used this function in the Java code? How? What format did you use? What I should use instead of "s" in this code?
conn is a database connection:
stmt = conn.createStatement();
rs = stmt.executeQuery("s");
I even tried PreparedStatement, but no luck.
Any help is greatly appreciated.

stmt.executeQuery("select blahblahblah, DECODE(fieldName, password), blahblahblah FROM blahblah...")

How can we use DECODE function in where clause.

Hi Guys,
I have to use DECODE function in where clause.

Can any one help me on this or any other aproach?
Thanks

I am looking for to decode the actual db value something in different for my report.
like if A then Accepted

what are you trying to do?
may be you are looking for
select * from tab1,tab2
where a.tab1 = b.tab2
and
   (decode(:code, 'A','Accepted') = <table_column>
    or
    decode(:code, 'R','Rejected') = <table_column>

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.
