Query Types and Use Cases

Data Retrieval Queries

Purpose: Extract data for analysis, reporting, and decision-making.

Sample Use Cases:

• Sales performance analysis

• Customer behavior insights

• Inventory tracking

• Financial reporting

• Marketing campaign effectiveness

Example Queries:

Sales Performance Analysis:

SELECT 
    product_name,
    SUM(quantity_sold) as total_quantity,
    SUM(revenue) as total_revenue,
    AVG(unit_price) as avg_price
FROM sales_data 
WHERE sale_date >= '2024-01-01'
GROUP BY product_name
ORDER BY total_revenue DESC
LIMIT 10

Customer Segmentation:

SELECT 
    customer_segment,
    COUNT(*) as customer_count,
    AVG(lifetime_value) as avg_lifetime_value,
    SUM(total_purchases) as total_purchases
FROM customer_analytics
GROUP BY customer_segment
ORDER BY avg_lifetime_value DESC

Expected Output:

[
  {
    "PRODUCT_NAME": "Premium Widget",
    "TOTAL_QUANTITY": 1250,
    "TOTAL_REVENUE": 45750.00,
    "AVG_PRICE": 36.60
  },
  {
    "PRODUCT_NAME": "Standard Widget", 
    "TOTAL_QUANTITY": 2100,
    "TOTAL_REVENUE": 31500.00,
    "AVG_PRICE": 15.00
  }
]

Aggregation and Analytics

Purpose: Perform complex calculations and statistical analysis on your data.

Sample Use Cases:

Example Queries:

Monthly Trend Analysis:

SELECT 
    DATE_TRUNC('month', order_date) as month,
    COUNT(*) as order_count,
    SUM(order_value) as total_value,
    AVG(order_value) as avg_order_value
FROM orders
WHERE order_date >= DATEADD('month', -12, CURRENT_DATE())
GROUP BY DATE_TRUNC('month', order_date)
ORDER BY month

Performance Metrics:

SELECT 
    region,
    SUM(sales) as total_sales,
    COUNT(DISTINCT customer_id) as unique_customers,
    SUM(sales) / COUNT(DISTINCT customer_id) as revenue_per_customer
FROM regional_sales
WHERE fiscal_year = 2024
GROUP BY region
ORDER BY total_sales DESC

Data Quality and Monitoring

Data Completeness Check:

SELECT 
    'customer_email' as field_name,
    COUNT(*) as total_records,
    COUNT(customer_email) as non_null_count,
    (COUNT(customer_email) * 100.0 / COUNT(*)) as completeness_percentage
FROM customer_data
UNION ALL
SELECT 
    'phone_number' as field_name,
    COUNT(*) as total_records,
    COUNT(phone_number) as non_null_count,
    (COUNT(phone_number) * 100.0 / COUNT(*)) as completeness_percentage
FROM
