Certainly! Based on your query, here's the corrected version:

SELECT 
  event_name, 
  ep.key AS event_parameter, 
  COUNT(*) AS event_count 
FROM 
  `foyer-work.analytics_349412478.events_20231129`, 
  UNNEST(event_params) AS ep 
GROUP BY 
  event_name, 
  ep.key

In this corrected version:

• I modified the query to use AS to provide aliases for the selected columns in the SELECT statement.
• I added the AS keyword to give the alias "event_parameter" to the ep.key column.
• I provided the alias "event_count" for the COUNT(*) expression.
• I adjusted the GROUP BY clause to include event_name and ep.key.

This syntax aligns with standard SQL conventions and should execute as intended. If you have any further questions or need additional assistance, feel free to ask!
