Hyunsik Choi commented on TAJO-346:
-----------------------------------
The patch looks good for me. For non-standard parts, Tajo mostly follows
PostgreSQL. In PostgreSQL, to_hex() is equivalence of hex in MySQL. You can
find the function details at
http://www.postgresql.org/docs/9.1/static/functions-string.html.
For consistency, could you please rename hex() to to_hex()?
Thanks!
