Example Workflows

Data Exploration with Claude Code

1. Connect to Database

   Connect to my SQLite database at ./sample_database.db
   

2. Explore Schema

   What tables are available in this database?
   

3. Examine Table Structure

   Show me the schema for the users table
   

4. Preview Data

   Show me some sample data from the users table
   

5. Run Analytics Queries

   Calculate total sales by product category
   

6. Export Results

   Export the query "SELECT product_name, SUM(quantity) as total_sold FROM orders GROUP BY product_name" to CSV file called sales_report.csv
   

7. Get Table Statistics

   Show me statistics for the users table
   

Common Use Cases

• Database Schema Discovery: Quickly understand database structure
• Data Quality Checks: Sample data to verify data integrity
• Ad-hoc Analysis: Run custom SQL queries safely
• Report Generation: Execute complex analytical queries
• Data Exploration: Browse tables and relationships with pagination
• Data Export: Export query results to CSV for external analysis
• Performance Monitoring: Track query execution times
