DECODE statement

please can someone kindly code the following line of SQL using the DECODE statement:
case when Student_Status in ('Registered','Repeat','Referral', 'Deferral')and GRADE <> 'MISSING' then EXAM1_RESULT else Null end as Valid_EX1
It will be most appreciated.
Thanks

This is what i need translated to DECODE:
"case when
Student_Status in ('Registered','Repeat','Referral', 'Deferral') and GRADE is not 'MISSING'
then EXAM1_RESULT
else Null end as Valid_EX1"
the issue is with the NOT 'MISSING' string.Check this. Just re-arrange of Andrés Muchiut post
DECODE (
STUDENT_STATUS
,'Registered',DECODE(GRADE,'MISSING',null,EXAM1_RESULT)
,'Repeat' ,DECODE(GRADE,'MISSING',null,EXAM1_RESULT)
,'Referral' ,DECODE(GRADE,'MISSING',null,EXAM1_RESULT)
,'Deferral' ,DECODE(GRADE,'MISSING',null,EXAM1_RESULT)
, null) Valid_EX1Hope this may help you...

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.

Logical Standby SQL Apply Using Incorrect Decode Statement

We are seeing statements erroring out on our logical standby that have been rewritten (presumably by sql apply) with decode statements that don't appear to be correct. For example, here is one of the rewritten statements.
update /*+ streams restrict_all_ref_cons */ "CADPROD"."OMS_SQL_STATEMENT" p
set *"APPLICATION"=decode(:1,'N',"APPLICATION",:2)*,
"STATEMENT"=dbms_reputil2.get_final_lob(:3,"STATEMENT",:4)
where (:5='N' or(1=1 and (:6='N' or(dbms_lob.compare(:7,"STATEMENT")=0)or(:7 is null and "STATEMENT" is null)))) and(:8="APPLICATION")
The problem comes in, we believe, with the attempt to write the value "APPLICATION" to the application column which is only a 10 character field. the value for the :1 bind variable is "N" and the value for :2 is null.
We see the following error on the logical standby:
ORA-00600: internal error code, arguments: [kgh_heap_sizes:ds], [0x01FCDBE60], [], [], [], [], [], []
ORA-07445: exception encountered: core dump [ACCESS_VIOLATION] [kxtoedu+54] [PC:0x2542308] [ADDR:0xFFFFFFFFFFFFFFFF] [UNABLE_TO_READ] []
ORA-12899: value too large for column "CADPROD"."OMS_SQL_STATEMENT"."APPLICATION" (actual: 19576, maximum: 10)
Is this a configuration issue or is it normal for SQL Apply to convert statements from logminer into decode statements?
We have an Oracle 10.2.0.4 database running on windows 2003 R2 64-bit os. We have 3 physical and 2 logical standby's, no problems on the physical standbys.

Hello;
I noticed some of your parameters seem to be wrong.
fal_client - This is Obsolete in 11.2
You have db_name='test' on the Standby, it should be 'asadmin'
fal_server=test is set like this on the standby, it should be 'asadmin'
I might consider changing VALID_FOR to this :

Document 278371.1 is showing its age in my humble opinion.
-----Wait on this until you fix your parameters----------------------
Try restarting the SQL Apply

How to determine INT and FLOAT in a DECODE statement

Can anyone help me with the following problem:
I have a column defined as a NUMBER(15,4). I am trying to determine the java type using the getScale() method in ResultSetMetaData. When the scale is greater than 0, then it is an float, else it is an int. In this case, the getScale() method should return 4. However, when querying with a DECODE statement on the NUMBER(15,4) field, the getScale() method always returns 0 and the value is therefore converted to an int. Anyone knows how to solve this problem?
Thanks

Alcides,
Oracle NUMBER data type is mapped to "java.math.BigDecimal" class.
You will find more information in the JDBC Developer's Guide and Reference which is part of the Oracle documentation and available from:
http://www.oracle.com/technology/documentation/index.html
Good Luck,
Avi.

Calling a stored proc in a decode statement

I am having a problem calling a store procedure in a SQL statement. I am using Oracle's thin driver.
I have been able to do the following:
select col1,
col2,
SOME_STORED_PROC(var1,var2,col3)
from some_table
where col3 = var3
However, when I try to call a stored procedure with-in a decode statement, the call fails. I have tested the call from a sql prompt and it works fine but it does not work when I execute the query in my Java program.
Here is an example of what I am trying to do:
select col1,
col2,
decode((select col1
from some_other_table
where col2 = var1), 'X',
SOME_STORED_PROC(var1,var2,col3),
SOME_OTHER_STORED_PROC(var2,var4,col5))
from some_table
where col3 = var3
Does anyone know if this type of call is not supported in Oracle's thin driver?
Thanks,

Problem with Decode statement

Hi
I am trying to achieve the following in my report:
If an employee has a surname of . (dot) or a first name of . (dot), the report should not display a dot. An employee's name is made up of surname, first name and middle name which should all be concatenated together. To try to achieve this, I have the following statement in my report:
decode(e.Surname, '.', ( LTRIM(RTRIM((INITCAP(e.FIRST_NAME)))||' '||INITCAP(e.MIDDLE_NAME)) ) ,
e.FIRST_NAME, '.', ( LTRIM(RTRIM((INITCAP(e.Surname)))||' '||INITCAP(e.MIDDLE_NAME)) ) ,
( LTRIM(RTRIM((INITCAP(e.SURNAME )))||', '||INITCAP(e.FIRST_NAME)||' '||INITCAP(e.MIDDLE_NAME)) ) ) as emp_name
FROM Employee e
Problem: The above statement is only working for those employees with surname of . (dot). It's not working for first names of dot. How can I use the decode statement OR is there any other way of doing it without using the CASE statement?
It seems my decode statement doesn't work with 2 different fields (surname, firstname) being tested within one decode statement.Thanks.

Thank you so much InoL . I have used the ltrim with Replace but now have a new problem.
Because I am joining Surname, First name and middle name together and put a comma after the Surname, the name now appears as follows:
, Maria Ane (if Surname is a dot)
Boiler, (if first name is a dot)
I would like to get rid of a comma and only have comma when surname or first name does not have a dot, i.e. for those people with full names e.g. Blake, Anna Marie.
InoL, how can I achieve this? Thanks.

Decode statement in a mapping involve Source Text File & Table.

Hi All,
Oracle 9i Warehouse Builder Client: 9.2.0.4.0
Oracle 9i Warehouse Builder Repository: 9.2.0.2.0
Oracle9i Enterprise Edition Release 9.2.0.5.0 - 64bit Production
Does OWB allow to use Decode statement in a mapping involves Source Text File and Oracle Table.
My understanding is it's not possible, since OWB makes use of Sqlloader. For this work arround could be make use of External Table instead of Text Flat File.
However I came across an old posting (June-2003) which says that this feature is available OWB 9.2.
Following is the url:
IF THEN LOGIC from Flat File to Table
Can someone please confirm this?
Thanks in Advance.
Regards,
Vidyanand

Hi all,
If you want to validate correctly this mapping you must to :
1. Right click on the mapping, then Configure
2. Right click on Sql Loader Data Files, then Create
3. Verify that the location name is correct and complete the Data File Name
4. OK
The validation is now OK.
I hope it will be help you

NULLIF Function converts to illegal DECODE Statement

I am converting a SQLServer 2000 application to Oracle 8i (release 3) using release 9.2.0.1.7 of the Migration Workbench. I have 39 SQLServer stored procedures which utilize the NULLIF function. The Migration Workbench is converting the NULLIF into a DECODE statement which results in the following PL/SQL compilation error.
Line: 59 Column: 40 Error: PLS-00204: function or pseudo-column 'DECODE' may be used inside a SQL statement only
T-SQL line --> SET @VAL = LTRIM(RTRIM(NULLIF(@VAL,'')))
PL/SQL line --> PROCNAME.VAL := LTRIM(RTRIM(DECODE(PROCNAME.VAL,'',NULL,PROCNAME.VAL)));
Why is the workbench creating an illegal use of the DECODE function in the PL/SQL ? Is there another workaround or 'trick' that I could apply so I don't have to manually correct a lot of code ?

Stephen,
Bug logged: Bug3393406
The workaround is to use select from dual:
SELECT LTRIM(RTRIM(DECODE(PROCNAME.VAL,'',NULL,PROCNAME.VAL)))
INTO PROCNAME.VAL FROM DUAL;
This is automatically done if 'SELECT' is used in place of 'SET' in T-SQL.

Help! format of decode statements with between or signs ?

Looking for an example of a decode statement with either a between/and or < > signs in the comparison field.
I have tried several variations, but none seem to work. Any help would be appreciated.
Here's a sample that doesn't work.
Select course_no, section_no, capacity, decode(capacity, (capacity < 12), Less than 12, (capacity between 13 and 15), 13-15, More than 15) from section;
Thanks in advance

Hi,
There is a limitation to the Case function, as it cannot be used in the PL/SQL (atleast upto Oracle 8i). Therefore, the only option left is Decode.
If you have to compare the values like capacity < 12 then display Less than 12. You can write it using combination of other functions.
For e.g. follow the steps below:-
1)If you deduct 12 from capacity : (capacity-12) [it will give result as +ve, 0 or -ve.]
2)If you have to narrow down the values to above three options, use function sign:
SIGN(capacity-12) [will result into +1, 0 or -1]
3)Then compare the values using Decode:
DECODE(SIGN(capacity-12),-1,Less than 12,Greater than or equal to 12)
The Decode can be used inside Decode(nested Decode) in above steps to compare more than one values (range between) to get the desired result. Hope have made it clear enough. If not, please let me know.
Cheers.

Decode Statement Inside the Case statement

Can we use Decode Statement inside a CASE Statement as show below --
It is giving an error -- Is the a better way to write with out any error
create or replace
function test (a varchar2) RETURN VARCHAR2
is
m varchar2(20);
begin
m :=
CASE
WHEN a IN (
'1009' -- (soon obsolete)
,'1010'
,'1019'
,'1051'
,'XGP'
,'XSC')
THEN (SELECT DECODE(v_lef_cd,'NAM','71','GLB','99','01') into m FROM DUAL)
-- ) THEN '01' -- UNITED STATES OF AMERICA
WHEN a IN (
'1069' -- South Africa
,'SAO' -- South Africa
,'SA' -- South Africa
) THEN '26' -- South Africa
ELSE NULL
END;
return m;
end;

Hi,
You can only use DECODE in SQL statements.
Your SELECT DECODE (...) INTO statement would work anywhere a PL/SQL statement is allowed; but PL/SQL statements are not allowed within CASE expressions.
Remember, the expression that comes after THEN in a CASE expression must be a single value.
I would write a function like this using IF ... ELSIF statements. It's a little more typing than CASE, but a lot easier to code, test and maintain.
If you want to use CASE, here's one way:
...     m := CASE
          WHEN a IN ('1069', 'SAO', 'SA')
               THEN '26'     -- South Africa
          WHEN a NOT IN ('1009', '1019', '1051', 'XGP', 'XSC')
          OR    a IS NULL
               THEN NULL
          WHEN v_lef_cd = 'NAM'
               THEN '71'
          WHEN v_lef_cd = 'GLB'
               THEN '99'
               ELSE '01'     -- USA
          END;This assumes that you have a variable v_lef_cd defined.
If you want, you can nest CASE expressions, like this:
...     m := CASE
          WHEN a IN ('1069', 'SAO', 'SA')
               THEN '26'     -- South Africa
          WHEN a IN ('1009', '1019', '1051', 'XGP', 'XSC')
               THEN CASE v_lef_cd
                      WHEN 'NAM'
                         THEN '71'
                      WHEN 'GLB'
                         THEN '99'
                         ELSE '01'     -- USA
                     END
          END;Always format your code, so you can see where the CASE expressions and each of the WHEN clauses begin and end.

Need help in decode statement to check condition

Hi All,
I have table emp with below structure
empno
work_phone_no
Home_phone
cell_phone
For the employee if work_phone & Home Phone is null then in place of work_phone we need to send the cell_phone number.
How to use the decode statement in this scenario to test for Home_phone
condition in the select statement.
select DECODE (work_phone_no,
null, cell_phone_no,office_phone_no )
from emp
Thanks

Hi,
Given the data you posted:
empno work_phone_no home_phone_no cell_phone_no
1     null          80032108556   8003210855
2     null          null          8003210000 and your requirement is
"If work & Home nunbers are null then display cellhone number in place of workphone number "
, then, as John said, you do not want the results you posted. You want:
1 null       80032108556
2 8003210000 null That is, on the first row, where empno=1, the work_phone_no is NULL because the home_phone_no is NOT NULL, and cell_phone_no is only to be shown when both of the other phone numbers are missing.
To get the results above, use CASE:
SELECT empno
,       CASE
            WHEN work_phone_no IS NULL
              AND home_phone_no IS NULL
            THEN cell_phone_no
            ELSE work_phone_no
        END AS work_phone_no
,       home_phone_no
FROM    ...If you really do want the results you posted, then, as John said, use NVL.

Hi Charan
i think it's all about using both CHARACTER and DATE values at the same time in a DECODE statment u should either use char or date datatype.
DECODE compares expr to each search value one by one. If expr is equal to a search, then Oracle Database returns the corresponding result. If no match is found, then Oracle returns default. If default is omitted, then Oracle returns null.
e.g.
If expr and search are 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.
for more pls have a look here
Hope this helps,
