sqlite rails active-record Ruby

I need help solving I've tried everything I can think of but I'm dealing with This might be a silly question, but I'm working on a project and hit a roadblock... I'm working with a frustrating scenario with my Rails application where I'm trying to use a Common Table Expression (CTE) to simplify a complex query involving multiple joins. However, when I execute the query, I get the behavior message `SQLite3::SQLException: no such column: my_table.column_name`. Here's the code snippet I'm using in my Rails model: ```ruby class MyModel < ApplicationRecord def self.complex_query sql = <<-SQL WITH ranked_data AS ( SELECT my_table.id, my_table.column_name, ROW_NUMBER() OVER (PARTITION BY my_table.id ORDER BY my_table.created_at DESC) as rn FROM my_table JOIN other_table ON my_table.other_id = other_table.id ) SELECT * FROM ranked_data WHERE rn = 1; SQL find_by_sql(sql) end end ``` I've checked that the `column_name` does exist in `my_table`, and I can query it normally without the CTE. The scenario arises only when I use it within this CTE. I also tried running the generated SQL directly in a SQLite client, and it worked fine there. It seems like the question lies within how ActiveRecord is handling the execution. I've made sure that I’m using SQLite version 3.38.0, which supports CTEs. To troubleshoot further, I also added a logging statement to print out the generated SQL, and it looked correct: ```sql WITH ranked_data AS ( SELECT my_table.id, my_table.column_name, ROW_NUMBER() OVER (PARTITION BY my_table.id ORDER BY my_table.created_at DESC) as rn FROM my_table JOIN other_table ON my_table.other_id = other_table.id ) SELECT * FROM ranked_data WHERE rn = 1; ``` Has anyone faced a similar scenario or has insights on why ActiveRecord might be unable to recognize the column during the execution of the CTE? Any advice on how to resolve this would be greatly appreciated! Any feedback is welcome!
