I am trying to execute the below code in hive:
create table xyz (name string,div int) ;
It shows error. Cant we use a column in hive with name div ? I have a large table that has a column div, executing that hql throwed me below error. That is how i tried with a smaller hql as the one above, and it shows same error. I am using hive 0.13.

Well the answer is found!
create table xyz (name string, `div` int);
This works! Surround div with "`" symbol and then it works.
I suppose div would be a keyword in hive (not found in any document though).
