Session Goal

The session aimed to address and resolve various programming errors in Python functions and SQL queries, focusing on enhancing error handling and syntax correctness.

Key Activities

  • Python Error Handling: Updated the find_superkey function to handle IndexError by checking for empty lists in covering sets.
  • SQL Syntax Corrections: Fixed SQL query syntax issues by using appropriate quotation marks for column names and addressing formatting errors.
  • Database Management: Utilized PRAGMA table_info() for inspecting database schemas and cursor.description for result set metadata.
  • SQLite Enhancements: Implemented parameterized queries to prevent SQL injection and used executemany for efficient batch inserts.

Achievements

  • Successfully implemented error handling in Python functions to prevent IndexError.
  • Corrected SQL syntax issues, ensuring proper execution of queries.
  • Enhanced database operations with improved security and efficiency through parameterized queries and batch processing.

Pending Tasks

  • Further testing of the updated functions and queries to ensure robustness across different datasets and scenarios.
