Amazon Athena: no viable alternative at input

Question

While creating a table in Athena; it gives me following exception:

no viable alternative at input

Answer 1

This happened to me due to having comments in the query.

I realized this was a possibility when I tried the "Format Query" button and it turned the entire thing into almost 1 line, mostly commented out. My guess is that the query parser runs this formatter before sending the query to Athena.

Removed the comments, ran the query, and an angel got its wings!
