Using decode function

Hi
Help needed.... i need to create column as L, R in fact table in business layer using below mentioned logic
select count(decode (type, '41',1,'51',1,'61',1))L, count(decode(type, '71',1,'31',1,'81',1))R
Waiting for the reply soon.
thanks & regards

Similar thread/question:
Re: How to count distinct excluding a value in business layer?
You may use:
L -> case when table.column in ('41', '51', '61') then 1 else 0 end
R -> case when table.column in ('71', '31', '81') then 1 else 0 end
Assuming that table.column is dimension attribute and you joined this table dimension to a fact table (steps 2 and 3 from the link above, add physical join to dimension table in the logical fact table source). L and R are two logical columns, using COUNT or SUM as aggregation rule.
Follow steps 1-7 (1-9 for complete) from the link above.

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 can we use DECODE function in where clause.

Hi Guys,
I have to use DECODE function in where clause.
like below
select * from tab1,tab2
where a.tab1 = b.tab2
and decode(code, 'a','approved')
in this manner its not accepting?
Can any one help me on this or any other aproach?
Thanks
-LKR

>
I am looking for to decode the actual db value something in different for my report.
like if A then Accepted
elseif R then Rejected
elseif D then Denied
these conditions I have to check in where clause.
>
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>
   or

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

       lag(val) over (partition by upper(dname) order by datetime) prev_val,

         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.

How to use decode function

Hello Friends,
I have a query that has different columns and I am not sure what the data type of each column is ...
I want to use decode function which displays the following if the value of the column is like this ..
if the value of column is -714E ie -700000000000000 then display as .A
if the value of column is -814E ie -800000000000000 then display as .B
NOTE ; don't know which column is having the value - and i don't know the data type of the column is ..
got to use the decode function for all the columns selected ..
I want to use decode function pls let me know how to write for this kind of requirement.
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 ..

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.

Using DECODE Function to change data

I am trying to use the Decode function in a SQL statement to find a field that has a specific type, and when it finds that type, I want to blank out the results in a different field.
For example:

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

Using DECODE Function in SQL

I need to know if there is any way to use a range of values from
database and decode to certain text. I am able to do with one
value.
for example:
DECODE(column_name,'216767111','Unlimited',column_name)
above argument works with one value only. How about a range,
ex: 216767000 to 216767111. I need to use only SQL. No PL/SQL.
Kinldly need some body's help
Thanks
Munis

Which version of the database? If it's 8i+ then you can use
the CASE function
for example:
(CASE WHEN column_name between 216767000 and 216767111
THEN 'Unlimited' ELSE column_name END)
This won't work in PL/SQL because they're introducing a CASE
statement does soemthing different.
rgds, APCHello Andrew
Thank you for response. I am using 8i. 8.1.6. However using
CASE, I get inconsistent data type, ORA-00932: inconsistent
datatypes. I able to work it out with other response using
DECODE(sign(. Do you have any idea why i am getting this error.
If time permits, let me know

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!

Problem using DECODE function

I'm trying to decode the following, but I seem to be having a syntax issue:
decode
       p.balls,p.strikes,
       1,0 '1-0 Count',
       2,0 '2-0 Count',
       3,0 '3-0 Count',
       0,1 '0-1 Count',
       0,2 '0-2 Count',
       1,1 '1-1 Count',
       2,1 '2-1 Count',
       3,1 '3-1 Count',
       0,2 '0-2 Count',
       1,2 '1-2 Count',
       2,2 '2-2 Count',
) as Count,what I'm trying to have happen is anytime the balls column has a '1' and the strike column has a '0' to decode to '1-0 Count' etc...

Decode compares the value of the first paramter with the values of the even parameters and returns the following odd parameters value when the first match is found. If the last parameter is an even numbered parameter it is taken as the default when no other matches are found.
So your code compares p.balls to p.strikes and if they match returns a 1 then it runs into a syntax error since you don't have any commas after the forth column.
If you want to perform a multicolumn compare in the manner you are showing you will need to use a CASE statement instead:
case when (p.balls, p.strikes) in ( (1, 0) ) then '1-0 Count'
     when (p.balls, p.strikes) in ( (2, 0) ) then '2-0 Count'
     when (p.balls, p.strikes) in ( (3, 0) ) then '3-0 Count'
     when (p.balls, p.strikes) in ( (0, 1) ) then '0-1 Count'
     when (p.balls, p.strikes) in ( (0, 2) ) then '0-2 Count'
end as "COUNT"

In Source, you are selecting from iidb_stg.stage_fn_base_translate, however in target query you are selecting from IIDB_STG.OPS_FN_SBJCT_TYPING. the only condition in both where clause is of FRM_TRACK_ID=308678, so i assume that the missing 2 records are not present in
IIDB_STG.OPS_FN_SBJCT_TYPING table. Modifying the target query might not resolve issue but you have to check why these two records are missing from this table in first place.

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
