Today i want report a valid alternative for ANDROID smartphone (for now), KONTALK.
It is an open source project with a great potential. It's present on Android Market.

The network infrastructure and protocol have been designed from scratch to be immune from any attempt to centralize the network. All servers inside the network will have the same power and capabilities over each other - the network will be able to maintain itself and make itself safe.

I invite you to test it on your smartphone devices.

Oracle Function to get a specific field from a String contains fields characters delimited

Hi All

Today a simple function to extract a field from a String contains characters delimited fields.
I want use regexp_substr function but there are some problems for null fields to extract, so i develop this simple function.

CREATE OR REPLACE FUNCTION
  get_field (iString IN VARCHAR2, iSeparator IN VARCHAR2, field_num IN NUMBER)
RETURN VARCHAR2
IS
   oField VARCHAR2(1024);
   position_field NUMBER;
   position_field_start NUMBER;
   position_field_end NUMBER;
BEGIN

  IF field_num = 1 THEN
     position_field :=  INSTR(iString,iSeparator);
     IF position_field > 0 THEN
        SELECT SUBSTR(iString,1,INSTR(iString,iSeparator)-1) INTO oField FROM DUAL;
     ELSE
        oField := iString;
     END IF;
  ELSE
      position_field_start :=  INSTR(iString,iSeparator,1,field_num-1);
      position_field_end :=  INSTR(iString,iSeparator,1,field_num);

      IF position_field_start > 0 THEN
      
            IF position_field_end = 0 THEN
               position_field_end := length(iString)+1;
            END IF;
           SELECT SUBSTR(iString,position_field_start+1,position_field_end-position_field_start-1) INTO oField FROM DUAL;
      ELSE
         oField := null;
      END IF; 
  END IF;

  RETURN (oField);
END;

For example you have this string '10;12;34;233;12' delimited by ';' character and you wont get third field.
You can call this oracle function in this way :

SELECT GET_FIELD('10;12;34;233;12',';',3) FROM DUAL;

Results will be : '34'.

I hope can help someone with same problem.
