ENCODING Error in Teradata v14 - forum topic by aarsh.dave

Hi,
I need to convert hexadecimal value to a decimal value. FOr that purpose, I have created the following query.
SELECT ZEROIFNULL(CAST(FROM_BYTES( TO_BYTES('0' || SUBSTR(col_a ,9,5),'base16'),'base10') AS INT)) AS col_A_dec FROM table_a
I am trying to run the following query on Teradata 14. However, I am getting error as "Unsupported ENCODING Type".
The same query runs fine when I login to another database.
Please let me know if there is something I am missing.
 
Thanks,
Aarsh
