Amazon Redshift Error - ERROR: 0A000: Specified types or functions (one per INFO message) not supported on Redshift tables

Question

When running the below query:

WITH sublevels AS (
SELECT 1 UNION ALL 
SELECT 1 UNION ALL
SELECT 1), FIELDA AS (SELECT (ROW_NUMBER() OVER ())::INT sublevel 
FROM          


        

Answer 1

In Redshift:

1. queries against information_schema run on the leader node only
2. queries against any "normal" tables run on compute nodes only

You cannot mix and match 1. and 2.
