title: Find sum of ASCII value in Hive
body: <p>I'm new for Spark and Hive. I would like to calculate the summation of ASCII value in column "name" in Hive Table. </p>
  
  <p>So in Hive, it has ascii() built-in function but it returns value only for first character. Does Hive provide the loop function to iterate all chars in name?</p>
