🕒 20:10–20:25
🏷️ Labels: Python, SQL, Database, Error Handling, Connection Management
📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal: The goal of this session was to address and resolve various issues related to database management using SQL and Python, focusing on table decomposition, error handling, and connection management.

Key Activities:

• Implemented Python code for decomposing tables in a database, using the cursor.execute() method to create and insert data into new tables.
• Resolved an SQL table name error by converting a frozen set object to a string for CREATE TABLE statements.
• Managed conflicts with existing database tables by providing solutions for dropping or renaming tables.
• Retrieved column names from an R table using SQL and Python, facilitating data manipulation.
• Corrected the creation of an SQLite table from a DataFrame by ensuring correct column names and data insertion.
• Addressed database connection errors by ensuring cursors are created before closing connections.
• Discussed best practices for maintaining active database connections to prevent premature closure issues.

Achievements:

• Successfully decomposed database tables and resolved SQL table name errors.
• Improved database management practices by handling existing table conflicts and optimizing connection management.

Pending Tasks:

• Further testing and validation of the implemented solutions to ensure robustness in different database environments.
