Fix NoSuchColumnError

in SQLAlchemy

Solution

NoSuchColumnError in SQLAlchemy usually occurs when your query references a column that either doesn't exist in the mapped table or hasn't been explicitly included in the query's selection. Ensure your table definition accurately reflects the database schema and that all required columns are present in the session's query or explicitly loaded using options like `load_only` or `defer` if they are not immediately needed. Verify the column names in your query match those defined in your SQLAlchemy model to avoid typos or misconfigurations.
