Session Goal

The session aimed to enhance error handling in Python functions and correct SQL syntax issues for database management.

Key Activities

• Implemented error handling in the find_superkey function to manage IndexError scenarios effectively.
• Updated SQL code to fix column format issues by converting column names into a comma-separated string.
• Corrected SQL query syntax by using appropriate quotation marks for column names to prevent ‘unrecognized token’ errors.
• Utilized PRAGMA table_info() in SQLite to inspect database schema and retrieve column information.
• Demonstrated the use of parameterized queries in SQLite3 to enhance database security against SQL injection.

Achievements

• Successfully updated the find_superkey function with robust error handling.
• Resolved multiple SQL syntax errors, ensuring proper table creation and data insertion.
• Improved database management practices by adopting secure coding techniques in SQLite.

Pending Tasks

• Further testing is required for the updated SQL queries to ensure compatibility across different database systems.
