Suggestion on decode function

DECODE(pc.prtyp_refno,4053,0,201979,0,201980,0,205495,0,201982,0,201981,0,1) = 0
could some body explain me what this exactly it means ,does pc.prtyp_refno is in the numbers provided or it should not be in the numbers given
Many thanks in advance

Hi,
Decode function compares column values to the specified list of possible values.
I suggest SQL Reference book.
This is what I found there:
DECODE compares expr to each search value one by one. If expr is equal to a
search, then Oracle returns the corresponding result. If no match is found, then
Oracle returns default. If default is omitted, then Oracle returns null.
If expr and search contain character data, then Oracle compares them using
nonpadded comparison semantics. expr, search, and result can be any of the
datatypes CHAR, VARCHAR2, NCHAR, or NVARCHAR2. The string returned is of
VARCHAR2 datatype and is in the same character set as the first result parameter.
Oracle automatically converts expr and each search value to the datatype of the
first search value before comparing. Oracle automatically converts the return
value to the same datatype as the first result. If the first result has the datatype
CHAR or if the first result is null, then Oracle converts the return value to the
datatype VARCHAR2.
Of course there is much more information :)

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

SQL*Loader and DECODE function

Hi All,
I am loading data from data files into oracle tables and while loading the data using SQL*Loader, the following requirement needs to be fulfilled.
1) If OQPR < 300, RB = $ 0-299, SC = "SC1"
2) If 300 < OQPR < 1200, RB = $ 300-1199, SC = "SC2"
3) If 1200 < OQPR < 3000, RB = $ 1200-2999, SC = "SC3"
4) If OQPR > 3000 USD, RB = > $3000, SC = "SC4"
Here OPQR is a field in the data file.
Can anyone suggest how do we handle this using DECODE function? Triggers and PL/SQL functions are not to be used.
TIA.
Regards,
Ravi.

The following expression gives you different values for your different intervals and boundaries :
SIGN(:OQPR - 300) + SIGN(:OQPR - 1200) + SIGN(:OQPR - 3000)

Case statement and Decode function both are not working in Select cursor.

I have tried both the Case statement and Decode function in Select cursor, but both the things are not working. On the other hand both the things work in just select statement.
See the first column in select (PAR_FLAG), I need to have this evaluated along with other fields. Can you please suggest some thing to make this work. And also I would like to
know the reason why decode is not working, I heard some where Case statement do not work with 8i.

Does this mean you are using 8i? Then scalar sub queries - selects within the select list, are not supported, along with CASE in PL/SQL.

Decode Function Help

Hi,
I am new to Oracle Development.
MY Requirement:
I need to populate a column 'ISMSG' with YES / NO based on the following condition
When code = 'S' or 'O'......the column 'ISMSG' should display YES else NO..
ie output should be like
CODE ISMSG
A NO
S YES
S YES
O YES
My code for Decode function:
CASE
WHEN c.code = 'S' THEN decode( c.code, 'S','YES','NO')
WHEN c.code = 'O' THEN decode( c.code, 'O','YES','NO')
END ISMSG,
Is my code correct? If so is this the best way to do it?
If not please correct the code.
Is there an efficient way to do it?
Thanks in advance.

Hi,
You can use either CASE or DECODE for that; there's no need to use both.
Using CASE:
SELECT c.code
,     CASE
         WHEN c.code IN ('S', '0') THEN 'YES'
                                           ELSE 'NO'
     END     AS ismsg
FROM    table_x   c;Using DECODE:
SELECT c.code
,     DECODE ( c.code
            , 'S'      , 'YES'
            , '0'      , 'YES'
                          'NO'
            )          AS ismsg
FROM    table_x   c;I suggest you forget about DECODE, and always use CASE, at least while you're just starting out.
CASE can do anything that DECODE can do. There are a few, simple situations where DECODE is a little shorter than CASE, and therefore a little clearer, but only a little, and, as I said, these are only simple situations, and CASE is clear enough in them.
DECODE is never much shorter or clearer than CASE. The converse is not true: there are many situations where CASE is much, much shorter and clearer than DECODE.

Logical Operations in SQL decode function ?

Hi,
Is it possible to do Logical Operations in SQL decode function
like
'>'
'<'
'>='
'<='
'<>'
not in
in
not null
is null
eg...
select col1 ,order_by,decode ( col1 , > 10 , 0 , 1)
from tab;
select col1 ,order_by,decode ( col1 , <> 10 , 0 , 1)
from tab;
select col1 ,order_by,decode ( col1 , not in (10,11,12) , 0 , 1)
from tab;
select col1 ,order_by,decode ( col1 ,is null , 0 , 1)
from tab;

example:
select col1 ,order_by,case when col1 > 10 then 0 else 1 end
from tab;
select col1 ,order_by,case when col1 <> 10 then 0 else 1 end
from tab;
select col1 ,order_by,case when col1 not in (10,11,12) then 0 else 1 end
from tab;As for testing for null, decode handles that by default anyway so you can have decode or case easily..
select col1 ,order_by,decode (col1, null , 0 , 1)
from tab;
select col1 ,order_by,case when col1 is null then 0 else 1 end
from tab;

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

SQL DECODE function

Oracle version: 9.2.0.1.0
Procob version: 9.2.0.1.0
Cobol version: 3.1.11
O.S. version: Windows XP
We have a pro*cobol file with the next conversion rule into a select defined with a cursor.
NVL(TO_CHAR(A.F_ALTA,'YYYYMMDD'),' '),
NVL(TO_CHAR(A.F_ESTADO,'YYYYMMDD'),' '),
we store the result data through a fetch of the cursor into two variables (W-F-ALTA and W-F-ESTADO) When the program executes an insert of these two values in a target table, we define the next conversion rule:
TO_DATE(DECODE(:W-F-ALTA,' ',NULL,:W-F-ALTA),'YYYYMMDD'),
TO_DATE(DECODE(:W-F-ESTADO,' ',NULL,:W-F-ESTADO),'YYYYMMDD')
Pro*Cobol and Cobol does not have errors when we precompile and compile the program but, when we execute the generated exe file, Oracle displays the next error:
ORA-01841 (full) year must be between -4713 and +9999, and not be 0
We think that the DECODE function is not understood by the cobol or pro*cobol interpreter. If we execute the same code without the DECODE function (only with TO_DATE function) there is no errors in the execution of the program
somebody knows if there are reported problems with this DECODE function in Pro*Cobol or Cobol and how to solve them?
Thanks

TO_DATE(DECODE(:W-F-ALTA,' ',NULL,:W-F-ALTA),'YYYYMMDD'),
TO_DATE(DECODE(:W-F-ESTADO,' ',NULL,:W-F-ESTADO),'YYYYMMDD')The problem is with the input values of :W-F-ALTA and :W-F-ESTADO. Using the first line as an example, what you are saying is if :W-F-ALTA is ' ', substitute it with NULL, any other value should be :W-F-ALTA, then output the TO_DATE value of whatever the result is.
So if the value of :W-F-ALTA is the wrong charater or in the wrong input format, TO_DATE function does not understand it.
See examples of success and failures below with your Bind variables substituted with typical values.

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.

Query
of Queries user guide

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:
DECODE(ADDR_TYPE,'HOME',PHONE='') HOME_PHONE

something like:
SQL> with t as
2   (select 219 id,
3           'BUS' addr_type,

5      from dual
6    union
7    select 219 id,
8           'HOME' addr_type,
9           null   phone
10      from dual

PL/SQL URL decode function

I am looking for a pl/sql url decode function. Does not appear to be in owa_util or htp/htf. Does any one have one please?

You can use the utl_url package that provides public APIs for both encoding and recoding purposes.

How can i use this expression in DECODE function?

My PNO table formart is
PNO PDate PCount
P001 08/27/05 09:45 20
P001 08/27/05 09:50 10
P002 08/27/05 03:40 20
P003 08/28/05 11:00 20
P003 09/28/05 10:00 20
P003 08/27/05 11:00 10
P003 09/27/05 04:00 50
I want to display total pcount for shift1(morning) and shift2(evening) & the date is 08/27/05
PNO Shift1(08/27/2005 08:00 to 12:30) Shift2(08/27/2005 02:00 to 05:30)
P001 30 0
P002 0 20
P004 10 50
So for shift1 condition is:
pdate>=08/27/2005 08:00 and pdate<=08/27/2005 12:30
So for shift2 condition is:
pdate>=08/27/2005 02:00 and pdate<=08/27/2005 05:30
If i tried to give this expression in decode function , its not working.
Please give me the sql query to solve this problem.
Millions of thanks in advacne

Error while replacing IF statements with DECODE function in procedure

Hi All,
I have created a procedure which has nested IF statements. Now I want to replace the IF statements with DECODE functions to improve performance.
Procedure:
IF (var_int_sev = '0')
THEN
var_sev := '2';
ELSE
SELECT sev
INTO var_int_sev
FROM errorconfig
WHERE errorcode = var_errorcode;
var_sev := var_int_sev;
END IF;
I converted the above IF statement into DECODE function as mentioned below:
var_Sev := DECODE(var_int_sev,0,2,SELECT severity FROM errorconfig WHERE errorcode=var_ErrorCode)
But it throws below error at the select statement used inside DECODE.
Error(58,51): PLS-00103: Encountered the symbol "SELECT" when expecting one of the following: ( - + case mod new not null others <an identifier> <a double-quoted delimited-identifier> <a bind variable> avg count current exists max min prior sql stddev sum variance execute forall merge time timestamp interval date <a string literal with character set specification> <a number> <a single-quoted SQL string> pipe <an alternatively-quoted string literal with character set specification> <an alternativ
Can someone help me in converting the IF to DECODE in the above case. Also how can we use a select statement inside decode.

instead of trying to rewrite all your code and hoping that the performance will be better, it's a better option to investigate and find out which part of your application is slow

Help on Decode function in Toplink

Hi,
I have a sql statement like this:
select field1, field2 from table1 where upper(field1) like 'ADELPHI%'
order by field1,
DECODE(TO_CHAR(NVL(LENGTH(TRANSLATE(field1,'A1234567890','A')),0)),'0',LPAD(field1 ,50),field1)
How would I converted this to toplink query?
I appreciate any help you guys can extend to me.

I just spent about a half hour writing a response here, and the damned forum timed out on me. #$^!@$#!^!@$%.
Here is the summary:
- Using TL Expressions and EJBQL are to allow Java developers who don't necessarily know SQL to write queries and to facilitate portability/maintainability of the apps. For REALLY gnarly queries, using TL Expressions or EJBQL won't buy you this. I.e., SQL is more expressive and easier for this kind of quer, so it's not easier to use, and frankly with the code needed to support it, it won't be easier to maintain or port... Bottom line, maybe SQL is the best option here?
- If you want to experiment, search for TO_CHAR on this forum, and the decode function in the javadoc. You need to build the expressions in pieces and you can treat expressions as arguments to other expressions -- in other words, you can build an expression like builder.leftPad(50, builder.get("field1")) and use it as one of the key/values in the hashtable to the decode function (in theory).
