> I tried to add some new rows into a table using an {{upsert select}}. The rows I was adding weren't in fact based on the existing rows, but I needed the {{select}} to come from somewhere.
> I put extra parentheses in by mistake, and got a NPE:
> {code}
> 0: jdbc:phoenix:172.31.31.143> upsert into linktab (id, first_val, second_val) select (next value for linktab_next_id, round(rand()*1000000000000), round(rand()*1000000000000)) from linktab;

> Note that the {{select}} part is of the form {{select (a, b, c) from...}} rather than {{select a, b, c from...}}.
> Removing the extra parentheses made the query complete fine, but it still shouldn't throw a NPE.
