How to write decode function in plsql

hi
guys
can u plz help me in this topic
.........

Hi ,
You could use the decode function in an SQL statement as follows:
SELECT supplier_name,
decode(supplier_id,      10000,      'IBM',
     10001,      'Microsoft',
     10002,      'Hewlett Packard',
          'Gateway') result
FROM suppliers;
The above decode statement is equivalent to the following IF-THEN-ELSE statement:
IF supplier_id = 10000 THEN
result := 'IBM';
ELSIF supplier_id = 10001 THEN
result := 'Microsoft';
ELSIF supplier_id = 10002 THEN
result := 'Hewlett Packard';
ELSE
result := 'Gateway';
END IF;
The decode function will compare each supplier_id value, one by one.

How to use Decode Function in Webi / Designer - BOE XI 3.1

Hi All,
I have a SQL query which needs to include in the webi report.
Below is the query :

AND SEC_MATURITY_DT > SYSDATE-1
and SECURITY.sec_sys_id=position.sec_sys_id
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))

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 ..

How to write Boolean function (If Then Else)?

Hi all,
I have a logic to write in the query. It is:
If (A = 0 and B = 0)
Then 0
Else
        If (A = 0 and B > 0)
        Then 100
        Else
               A/B (we want to show %)
How to use boolean function to write this Netted If Else statement? Thank you in advance!

Hi
If (A = 0 and B = 0)
Then 0
Else
If (A = 0 and B > 0)
Then 100
Else
A/B (we want to show %)
1. create a formula in the query designer. and use this formula for if - else
( ( (A==0) AND (B==0) ) * 0) + ( ( a==0 ) AND (B >0 ) * 100 + (A/B*100) )
: denotes THEN
+ : denotes ELSE
See if this works.

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!

How to write a function read line from a file in FDK?

Hello,
I want to write a function that can read a file in line by line in FDK. How do I write it. If FDK could not. Is there any the way? Please help.
Thank you,
Thai Nguyen

Thai,
You can use the "channel" functions for this. I'm far from an expert on channel programming but I've read files line-by-line successfully by going one character at a time, looking for a carriage return.
You can open up the file channel with something like:
ChannelT chan;
FilePathT *path;
UCharT ptr[1];
IntT numRead;
path = F_PathNameToFilePath("C:\\temp\\mydoc.txt", NULL, FDefaultPath);
if((chan = F_ChannelOpen(path,"r")) == NULL)
return;
//read the first character
numRead = F_ChannelRead(ptr, sizeof(UCharT), 1, chan);
...then you can call F_ChannelRead iteratively to build the string in a buffer, looking for a carriage return (ASCII 13) and stopping there. (that is, ptr[0] == 13).
There might be a better way. This is just the way I've gotten it to work. It probably is not a good method for unicode files.

How to write Decode ?

Hi All,
please tell me how to write below statement in using decode statement in a single query.
if A1 IS NULL and A2 IS NOT NULL then
C := 'NA';
elsifF A1 IS NULL AND A2 IS NULL
then
C:='Success';
end if;
Regards,
Subir

Also you should use
case for this.Why? It can just as easily be achieved with decode.

How to write printing function using JSP?

dear all,
i want to add a printing function in my project but i do not know how to do it? could anyone teach me how to do it?
thanks
eric

salut eric,
you can do it this way :
1 - create a html link in your code to this javascript
function : (I am using Struts, but you can write it in
pure html
<html:link href="#bodyStart"
onclick="openWindowForPrinting()"
titleKey="msg.status.print"> <bean:message
key='app.print' />
<script language="JavaScript">

</script>
</html:link>
>
>
2 - here is the javascript function : it open a window
with the "print.jsp" page.
function openWindowForPrinting(){
window.open('/your_project/pages/common/print.jsp','',
'left=150, top=150 , status=no, directories=no,
toolbar=no, menubar=yes, location=no, scrollbars=yes,
resizable=yes, dependant=yes');
3 : here is the print.jsp page : You have only to
create a session variable called
"currentBodyRelativeLocation", which content the
relative URL to the page you want to print (for
example, the boby of the current page).
<%@ taglib uri='/WEB-INF/tlds/perso.tld'
prefix='perso' %>
<html>
<head>
<perso:csslink page='${cssRelativeLocation}' />
</head>
<body onload="var SymTmpWinOpen = window.open; window.open = SymWinOpen; printPage();; window.open = SymTmpWinOpen;">
<body>
<jsp:include page="${currentBodyRelativeLocation}"/>
</body>
<script language="JavaScript">

</script>
</html>
<script language='javascript'>
function printPage(){
window.print();
window.close();
</script>
hai,
i'm not very understand how is your code work. when i write html code, do i need to mind about this code: "msg.status.print" ? what is this code mean?
i have too much question on this thing. would you mind to be further explain to me? or is it any reference for me to refer? i'm really new to write printing function on JSP.
i never write this function before. i'm feel so lost.....:(
thanks again

How to write a function module?

How can i write a function module that does the same thing as BAPI_FLIGHT_GETLIST in the SAP system?

Hi
Hope it will help you.
Reward if help.
Function Modules;
Check this matter.
Function Modules are Global ABAP programs created by SAP for reusable purpose.they have IMPORT,EXPORT and TABLE parameters, and EXCEPTIONS to through when error occurs.
You can create them from TCode SE37.
Go through the following doc:
Function modules are cross-program, reusable procedures that are organized into function groups, and whose functions are implemented between the statements FUNCTION and ENDFUNCTION. Function modules and their interfaces are created in the Function Builder.
Function Module Interfaces
The parameter interface of a function module is defined in the Function Builder. It includes the definition of interface parameters and the specification of exceptions that can be triggered by a function module. The Function Builder automatically generates comment lines below the FUNCTION statement in the source code of the function module, which represent the interface of the function module with the following syntax:
Syntax
... [IMPORTING parameters]
[EXPORTING parameters]
[CHANGING parameters]
[TABLES table_parameters]
[{RAISING|EXCEPTIONS} exc1 exc2 ...]
The syntax and semantics of IMPORTING, EXPORTING, CHANGING, RAISING, and EXCEPTIONS mainly correspond to the definition of method interfaces with [CLASS-]METHODS. The additional option of defining table parameters using TABLES is obsolete.
Interface parameters
The interface parameters are defined on the relevant tab pages in the Function Builder.
IMPORTING parameters are input parameters. When the function module is called, a suitable actual parameter must be specified for every non-optional input parameter. The content of the actual parameter is passed to the input parameter when the call is made. The content of an input parameter for which 'pass by reference' is defined cannot be changed in the function module.
EXPORTING parameters are output parameters. When the function module is called, a suitable actual parameter can be specified for every output parameter. The content of an output parameter that is defined for 'pass by value' is transferred to the actual parameter if the function module is completed without errors. An output parameter that is defined for pass by reference is not initialized when the function module is called.
CHANGING parameters are input and output parameters. When the function module is called, a suitable actual parameter must be specified for every non-optional input or output parameter. When the function module is called, the content of the actual parameter is passed to the input/output parameter, and when the function module is completed, the content of the input/output parameter is passed to the actual parameter.
TABLES parameters are table parameters. Table parameters are obsolete CHANGING parameters that are typed as standard tables with a header line. If an internal table without a header line or a table body is passed as an actual parameter to a formal parameter of this type, an empty local header line is generated in the function module. If an internal table with a header line is used as an actual parameter, both the table body and the header line are passed to the function module. Pass by value is not possible in formal parameters defined using TABLES. Formal parameters defined with TABLES can be replaced by formal parameters defined with CHANGING. A local work area can be created for the internal table in the function module by using the addition LIKE LINE OF itab of the DATA statement.
Exceptions
The exception of a function module are defined on the Exceptions tab page in the Function Builder. Here you can select exception classes to define whether class-based exceptions are declared or non-class-based exception are defined. Class-based exceptions are represented in the above syntax by RAISING, and non-class-based exceptions are represented by EXCEPTIONS.
The addition RAISING is used to declare class-based exceptions that can be propagated from the function module to the caller. Exceptions in the categories CX_STATIC_CHECK and CX_DYNAMIC_CHECK must be explicitly declared, otherwise a propagation can lead to an interface violation. A violation of the interface leads to the treatable exception CX_SY_NO_HANDLER. Exceptions of the category CX_NO_CHECK are implicitly always declared. The declaration of exceptions of the category CX_STATIC_CHECK is statically checked in the syntax check. For exceptions of the category CX_DYNAMIC_CHECK, the check is not performed until runtime. In a function module in which class-based exceptions are declared with the RAISING addition, the statement CATCH SYSTEM-EXCEPTIONS cannot be used. Instead, the relevant treatable exceptions should be handled in a TRY control structure.
The addition EXCEPTIONS is used to define a list of non-class-based exceptions that can be triggered in the function module using the statements RAISE or MESSAGE RAISING. Exceptions defined in this way - as with formal parameters - are bound to the function module and cannot be propagated. If an exception of this type is triggered in a function module, and no return value has been assigned to it with the homonymous addition EXCEPTIONS of the CALL FUNCTION statement when the call was made, this leads to a runtime error.
Note
For new developments after release 6.10, SAP recommends that you work with class-based exceptions that are independent of the function module.
RFC is a technology which is used to access a functions (Modules) from
the remote systems.
If a function module is set as remote enabled which can be access from
the remote system via RFC.Eg: U can access the Remote enabled function modules in ur VB,Webdynpro,Java,Visual composer program.
A function module can be set as remote enabled by SE37->Go to ur FM->click the option Button "remote enabled".
But Normal function modules can not accessd from the remote system.
Good Example for RFC enabled function module is : BAPI(Business Application Programming Interface)
Note: All BAPIs are Remote enabled but not all remote enabled function modules are BAPI.
CALLING A FUNCTION MODULE:
1)In U ABAP Editor --> Click "Patter" ---> Selection Option Button "Call Function"
--> Write the Corresponding FM name --> Hit Enter
2)The appropriate import ,export Parameters will be displayed in ur editor
3)Pass the Values Here.

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 to write a function

Is there a way to write a function
function f(c sys_refcursor) return number;
which is called from sql (for example like this)
select f( cursor(...) ) from dual
and returns the number of columns specified in the cursor expression;
One suggestion could be to use the dbms_sql package, but it is impossible to invoke the dbms_sql.to_cursor_number function as it wants IN OUT parameter, and SQL doesn't allow in out parameters. so what to do.
thanks in advance

DimaK wrote:

3          buffer          TStrings;

11                  csvLine := csvLine || buffer(i);
12                  if i != buffer.Count then
13                          csvLine := csvLine || ',';
14                  end if;
15          end loop;
16
17          return( csvLine );
18 end;
19 /
Function created.

No errors.

FUNKYFOO,TOKENISE,TSTRINGS,WEBURL
SQL>
and returns the number of columns specified in the cursor expression;No. Reason - a ref cursor does not have a describe interface. Thus you cannot determine the SQL projection of the cursor and number of columns, column labels and column data types and precision in the projection.
But the question is.. why on earth do you want to have such a function? What purpose is it suppose to fulfill? What is the underlying requirement that needs to be met? As from what you've stated here, it seems to be pursuing a very incorrect solution for the unknown problem at hand.

How to write a function with table name as parameter

I created a function like this:

end;
i got an error: table or view does not exist.
Could somebody tell me how to fix it?
