Subj:   Re: Small function in teradata
 
From:   Michael Larkins



Sreenivasa:

The only thing wrong with what you wrote was that in Teradata you must tell it the length of a CHAR.

     > > CAST(MOD(EXTRACT(YEAR FROM CURRENT_DATE),4)  AS CHAR(1)) = 0
             /* should be '0' if using CHAR to prevent another conversion */

However, it would be much more efficient and faster to not convert it to a CHAR as in the following:

     WHERE MOD(EXTRACT(YEAR FROM CURRENT_DATE),4) = 0

Hope this helps,
