Hi

I need change day to hour from my date for example:
I have following date format: 01 22:43:22 - where 01 is a day. Now I want to include (add) this day to hours so I want to have: 46:43:22.

Thanks for any help and tips

Best regards

It appears you don't have a date format, but rather a character string that represents a period of time.
A stored function might be of use here:

Code:
SQL> CREATE OR REPLACE FUNCTION my_date_format(p_in VARCHAR2)
RETURN VARCHAR2
AS
   l_string VARCHAR2(10);
BEGIN
   l_string := (24*to_number(substr(p_in,1,2)) + to_number(substr(p_in,4,2)))||substr(p_in,6,6);
   RETURN l_string;
END;
/
Function created.
SQL> select my_date_format('01 22:14:22') from dual;
MY_DATE_FORMAT('0122:14:22')
-------------------------------------------------------
46:14:22
SQL> select my_date_format('03 22:14:22') from dual;
MY_DATE_FORMAT('0322:14:22')
-----------------------------------------------------------
94:14:22

Of course, if you can have more than two digits' worth of days, you will need to change the code, but this should get you within striking distance.
 
And, as an alternative to Carp's fine function, to illustrate how to:

1) Accomplish your objective without a function
2) Leverage Oracle's implicit data-type conversions
3) Accommodate variable-length inputs

...here are more code:
Code:
select * from bartec;

DT
------------
0 10:17:10
1 14:22:40
10 03:50:60
100 10:20:30

select 24*substr(dt,1,instr(dt,' ')-1)
        + substr(dt,instr(dt,' ')+1,2)
       || substr(dt,instr(dt,':'),6) result
from bartec;

RESULT
-----------
10:17:10
38:22:40
243:50:60
2410:20:30
