Boolean function

Hi
I am using standard Boolean function ' if '. I want to set the confition in that. How can I do that ?? Either right click or double click is not leading to any screen where I can put my condition. If length comes to 15 I want to route to one channel and when it comes to 20, I want to route to channel two. How to set this condition in "if" node function ?? Basically I want navigation to use this funcation.
Thanks
kumar

Add the field you wish to check
add the length (text) function.
Add the equalS function and build this up....
Look at Page 23 here for an example... https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/be05e290-0201-0010-e997-b6e55f9548dd

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.

HOW TO MAKE A BOOLEAN FUNCTION IN LABVIEW5.0

I want to use a boolean funtion but it does not exist in existing functions?so how can I do it?I final aim is how to make a VALVE boolean function and how to use it?please teach me,experts! Thank you very much!

Hi,
what do you mean by "boolean function"?
For boolean operations you can use
1. Case structure. It is located in Functions->Structures
2. Boolean functions (such as AND, OR, NOT, etc.). They are located in Functions->Boolean
3. Comparison functions (such as equal?, greater?, less?, etc.). They are located in Functions->Comparison
You have to give more info about your problem.
Good luck.

To use Boolean function in DECODE or CASE statement

Hi all
I have a scenario where i need to use a boolean function inside DECODE statement. When i tried this way iam getting "ORA-06553: PLS-382: expression is of wrong type".
I doubt whether i can use boolean function inside DECODE or not?
My query will be like this:
select decode(my_fuction( ),'TRUE',1,'FALSE',0) from dual;
Any help is highly appreciated.
Thanks
Sriram

Overloaded functions must differ by more than their
return type . At the time that the overloaded
function is called, the compiler doesn't know what type
of data that function will return. The compiler cannot,
therefore, determine which version of the function to
use if all the parameters are the same.

Can you use boolean function in where clause

Hi,
I have a boolean function. Is it possible to use it in where clause of query.
Eg;
is_prime(13) returns boolean
select 1 from dual where is_prime(13)

What about something like this
Create or replace function boolret(id number) return boolean as
begin
If id <10 then
return true;
elsif id>10 and id<100 then
return false;
else
return null;
end if;
end;
1 declare
2 id_cat boolean;
3 begin
4 id_cat:= boolret(8);
5 dbms_output.put_line(id_cat);
6* end;
SQL> /
dbms_output.put_line(id_cat);
ERROR at line 5:
ORA-06550: line 5, column 2:
PLS-00306: wrong number or types of arguments in call to 'PUT_LINE'
ORA-06550: line 5, column 2:
PL/SQL: Statement ignored
It seems PL/Sql doesn't have any datatype like Boolean,But it handles Boolean like datatype.

How to Use a boolean function in a process

Hi,
I created a boolean function named change_pwd with 3 varchar2 parameters : login_name, old-pwd and new_pwd. I would like to use it in a process but I can't, this is how I do it : 
select change_pwd (
v('P12_Login'),v('P12_Old_Pwd'),v('P12_New_Pwd')) from dual;
 
Benn

I got this error : 
ORA-06550: line 2, column 8: PLS-00382: expression is of wrong type ORA-06550: line 2, column 1: PLS-00428: an INTO clause is expected in this SELECT statement
 
and here is my function : 
create or replace function "CHANGE_PWD" 
(p_username in VARCHAR2, 
p_old_password in VARCHAR2, 
p_new_password in VARCHAR2) 
return boolean 
is 
l_count number; 
l_password varchar2(4000); 
l_stored_password varchar2(4000); 
l_idcontact number; 
begin 
-- Check to see if the user is in the user table 
select count(*) into l_count from CONTACTS where MATRICULE = p_username;

select u.MOTDEPASSE, u.IdContacts into l_stored_password, l_idcontact from UTILISATEURS u, CONTACTS c where u.IdContacts = c.IdContacts AND c.MATRICULE = p_username; 
 
-- apply the cash function 
l_password := user_hash(p_username, p_old_password); 
 
-- compare the hashed password with the stored password 
if l_password = l_stored_password then 
-- change password 
update UTILISATEURS set MotDePasse = user_hash(p_username, p_new_password) where idcontacts = l_idcontact;
return true; 
else 
return false; 
end if; 
else 
return false; 
end if;

Best design for Boolean function from simple query

Hello,
what is the most efficient, shorter, readable, simple way to make a boolean function that simply return true or false from a simple query that return 0 or 1 to n records?
Is this solution using a cursor's the best (working...):
   FUNCTION is_date_present (p_date IN DATE)
      RETURN BOOLEAN
   IS
      CURSOR chk_cursor
      IS
         SELECT COUNT (*)
           FROM target_dates
          WHERE target_date = p_date;
      nb   NUMBER := 0;
   BEGIN
      OPEN chk_cursor;
      FETCH chk_cursor
       INTO nb;
      CLOSE chk_cursor;
      IF nb >= 1
      THEN
         RETURN TRUE;
      ELSE
         RETURN FALSE;
      END IF;
   END;Performance, clarity and simplicity are important...
Thanks

Well, I prefer (not tested):
FUNCTION is_date_present (p_date IN DATE)
RETURN BOOLEAN
IS
nb NUMBER := 0;
BEGIN
SELECT COUNT (*)
INTO nb
FROM target_dates
WHERE target_date = p_date;
IF nb >= 1 THEN
RETURN TRUE;
LSE
RETURN FALSE;
IF;
END;Regards,
MiguelWhy count multiple records when you only care if you get at least 1 occurrence? Just wasted cycles.
FUNCTION is_date_present (p_date IN DATE)
RETURN BOOLEAN
IS
nb NUMBER := 0;
BEGIN
SELECT COUNT (*)
INTO nb
FROM DUAL
WHERE EXISTS
      SELECT NULL
      FROM target_dates
      WHERE target_date = p_date
IF nb >= 1 THEN
     RETURN TRUE;
ELSE
     RETURN FALSE;
END IF;
END;Or you could just add a ROWNUM = 1 on to yours, either way.

Boolean Function Ifs not giving proper out put

Hi ,
I am using boolean function Ifs in message mapping of one of my scenerio.
My problem is First argument have exist function and if first argument is true it gives value of second argument but if is false , I am passing a Constant value in else condition(3rd argument) it give no out put.Can you suggest how can i resolve it.

Hi Mohit,
In your case you need not to use IFs , instead make use of boolean function If , it will work fine for you.

Boolean() function gives true in all cases

The implementation of the boolean() function in BPEL (version 10.1.2.1.0) have an FATAL ERROR.
boolean(0) gives 1 and
boolean(false) gives 1
I have tried to make a TAR, however I cannot connect to meta-link today.

Thanks for your answer Clemens.
Perhaps, I missed to send you my test-case.
Try with the following assign, based on the schema below with input and output defined as boolean (in default generated bpel-syncron project):
<assign name="Assign_1">
<copy>
<from expression="boolean(bpws:getVariableData('inputVariable','payload','/client:TestIfProcessRequest/client:input'))"/>
<to variable="outputVariable" part="payload" query="/client:TestIfProcessResponse/client:result"/>
</copy>
</assign>
<types>
<schema attributeFormDefault="qualified"
elementFormDefault="qualified"
targetNamespace="http://xmlns.oracle.com/TestIf"
xmlns="http://www.w3.org/2001/XMLSchema">
<element name="TestIfProcessRequest">
<complexType>
<sequence>
<element name="input" type="boolean"/>
</sequence>
</complexType>
</element>
<element name="TestIfProcessResponse">
<complexType>
<sequence>
<element name="result" type="boolean"/>
</sequence>
</complexType>
</element>
</schema>
</types>
It gives the result
<TestIfProcessResponse>
<result>true</result>
</TestIfProcessResponse>
no mather what I gives as input in the BPEL Console.
I have tried with 0, 1, true, false.

Invoking a Database boolean Function from Java

Hi,
I have the following boolean database function --
FUNCTION isPositive(p_count NUMBER) RETURN BOOLEAN
IS

 return true;
END;I read somewhere that CallableStatement doesn't support the boolean function.
I tried to use CallableStatement to invoke the above function as follows --
 String sql = "begin ? := helperpkg.isPositive(?); end;";
 CallableStatement cs = jdbcConn.prepareCall(sql);
 cs.registerOutParameter(1, java.sql.Types.BOOLEAN);
 cs.setInt(2, -5);
 cs.execute();
 return cs.getBoolean(1);But it gave me the exception --

Creating multiple input terminals for a boolean function?

Hi,
I was wondering how to create multiple input terminals for a boolean function? I'm pretty sure i've done so before, but I can't seem to remember how, I need to for a school assignment, and i've searched in the help in the program for about 3 hours before switching to google, which also didn't give me an answer.
I'm beginning to feel quite stupid especially since it is something quite simple I'm sure, but I just don't know how
my teacher is currently on vacation and since it was an assignment I actually should've done in september I doubt any of the other students still recalls.
What I want to do is create an or-function, with 3 boolean inputs, does anyone know how to do that?
Thanks

Look again at the picture posted above, it shows exactly what you need, the "compound arithmetic" node, found on the numeric and the boolean palette.
Resize it to the desired numbers of inputs.
right-click for the desired operation (AND, OR, XOR, etc.)
right-click on each terminal to invert the particular input or output (shows as small circle).
(I am not sure who gave the one star rating above, but that was certainly undeserved )

Test Boolean Function

Dear All
How I Can test boolean function that return true or false.

Hi,
Write a Wrapper Function , that is, another function that is wrapped around your first fucntion, which you can call from SQL, and call it.
CREATE OR REPLACE FUNCTION check_mobile_varchar2 (p_mobile IN VARCHAR2)
RETURN VARCHAR2
IS
    return_string   VARCHAR2 (5) := 'FALSE';
BEGIN
    IF check_mobile (p_mobile)
    THEN
        return_string := 'TRUE';
    END IF;
    RETURN return_string;
END check_mobile_varchar2
/To test:
SELECT txt
,       CHECK_MOBILE_VARCHAR2 (txt)    AS check_mobile
FROM    table_x
;This assumes you really want a function that returns a BOOLEAN, and therefore can't be used in SQL. A lot of folks just write functions that return 'TRUE' or 'FALSE' (or 'T' or 'F', 1 or 0) in the first place.
If check_mobile is in a package, check_mobile_varchar2 should be in the same package.

Calling boolean function from tree query

Hi all,
I have placed a tree on my sidebar region from the following query
select PAGE_NO id,
PARENT_PAGE_NO pid,
NAME name,
'f?p=&APP_ID.:'||page_no||':&SESSION.' link,
null a1,
null a2
from #OWNER#.APEX_PAGES
WHERE page_no = :APP_PAGE_ID
AND nvl(navigation,'N') = 'Y'
Its running perfectly fine. Now i have my custom function "isUserAllowed(app_user, name_of_node, isParent)" which returns a boolean expression is the logged in User has access privilege on that node.
How can i run my function inside the tree query so that node is visible only for those values in which my function returns "true"? and not on others?
With Regards,
Sunil Bhatia

The "wrapper" function would actually be pretty easy - just another function to call the one returning the boolean and convert it to some other value, numeric or character. something like (untested)
<pre>
FUNCTION wrapper_function(P_whatever varchar2) return varchar2 IS
v_return_value_c varchar2(5);
BEGIN
r_return_value_c := case boolean_function(p_whatever)
when true then 'true'
else 'false;
return v_return_value_c;
END;
</pre>
Using the function in the WHERE clause could look something like this (untested, but should work if done correctly)
<pre>
select whatever
from your_table
where wrapper_function(whatever) = 'true'
</pre>

Above is what I thought was a simple function that returns a boolean value. I am doing a asp.net project and i need a simple function to call as a test. I have written a simple function that returns an int, string already and i dont understand the error above....
Can some one give me an example of a function that returns a boolean value based around a simple table like the emp table for example. That would be great thanks ( or else tell me whats wrong with my simple ha ! function above)

I'd rather put some sort of wrapper on the oracle side. The reason for this is that the application i'm building is designed to allow users run functions or procedures and pass as many arguments as they want to the c# class. This is what I've been working on but there are data type issues arising.
create or replace function convFunc
--funcName varchar2
return number
as
a boolean;
b number;
begin
--a := myFunction();
a:=funcName
--Is there any way I can pass in the name of the function to be called
and concatenate the () brackets to it and assign it to a. I tried
funcName:= funcName||(); but it wont let me do that. The second problem is that as the function returns true or false but the function name comes in as a string there is a type mis match... There has to be some way of solving the problem on the oracle side. Again all I want from the user is the function name and parameters
Sorry if i'm annoying people with similar posts
if a=true then
b:=1;
return 1;
else
b:=0;
return 0;
end if;
end;
