Is it possible to convert ascii data in binary?

Question

Hi all.
In my one table there is a column which contains ascii value. i want to convert it in binary. It it possible in oracle?
eg field value:1250ÿ it should be 125011111111
kindly tell how to do this.
i have tried this using a simple java program but doesnot work for some ascii values.
thank you

Answer 1

I created two functions :
create or replace FUNCTION dec2bin (N IN NUMBER) RETURN VARCHAR2 IS
binval VARCHAR2(64);
N2 NUMBER := N;
BEGIN
WHILE ( N2 > 0 ) LOOP
binval := MOD(N2, 2) || binval;
N2 := TRUNC( N2 / 2 );
END LOOP;
RETURN binval;
END dec2bin;
And other :
create or replace function to_ascii( inSource IN VARCHAR2 )
return varchar2 AS
ResultString varchar2(381); -- 3 * possible length of source
TempNumber number;
begin
for i in 1..length( inSource ) loop
TempNumber := dec2bin ( ascii( substr( inSource,i,1 ) ) );
ResultString := ResultString || trim( to_char(TempNumber,'00000009'));
end loop;
return ResultString;
end;
Now, in sqlplus : (just to show the binary string)
column mybin for 9999999999999999999999999999999999999999
SQL> select to_ascii('g') mybin from dual;
MYBIN
01100111
SQL> select to_ascii('girish') mybin from dual;
MYBIN
011001110110100101110010011010010111001101101000
