  Use Aliases Properly: If you are using table aliases, ensure that they are correctly referenced in the ON clause.
  
  
  Check for Unsupported Expressions: Avoid using unsupported expressions or functions in the ON clause. Only use simple equality or inequality comparisons.
  
  
  Test the Query: After making the necessary changes, test the query again to see if the error persists.
