Question

I have a date variable as 24-dec-08. I want only the 08 component from it.

How do I do it in a select statement?

e.g.:

select db||sysdate  --(this is the component where I want only 08 from the date)  from gct;

The easiest way is to use the to_char function this way:

to_char(sysdate, 'YY') 

as documented here.

If you need the integer value, you could use the extract function for dates too. Take a look here for a detailed description of the extract syntax.

For example:

extract(YEAR FROM DATE '2008-12-24')     

would return 2008.

If you just need the value of the last two digits, you could apply the modulo function MOD:

mod(extract(YEAR FROM DATE '2008-12-24'), 100)  

would return 8.
