What is “Oracle pricing” in PostgreSQL?

It’s simply a nickname for queries that total, average, or otherwise measure the cost of products whose name contains “Oracle” in a PostgreSQL-based ecommerce schema.

Which tables are involved?

You need Products for the unit price, OrderItems for quantities, and optionally Orders or Customers for filtering by dates or buyers.

How do I calculate the total revenue from Oracle products?

Join Products to OrderItems, multiply price × quantity, and sum the result.Use ILIKE '%oracle%' to catch case variations.

Why use `COALESCE` in pricing queries?

Missing or NULL prices break math. COALESCE(price,0) guarantees arithmetic safety so totals don’t return NULL.

How can I find average selling price per Oracle product?

Group by the product id or name and divide the sum of revenue by the sum of quantities to get a true weighted average.

Best practices for performance?

Add an index on Products.name with LOWER(name) for faster ILIKE searches.Keep price in NUMERIC(12,2) to avoid rounding errors.

Common mistakes to avoid

Don’t forget the quantity multiplier—summing only prices under-counts revenue. Use JOIN, not CROSS JOIN, to prevent exploding row counts.

Why How to Calculate Oracle Pricing in PostgreSQL is important

How to Calculate Oracle Pricing in PostgreSQL Example Usage


-- Total revenue from Oracle products in 2024
SELECT  SUM(oi.quantity * p.price) AS oracle_revenue_2024
FROM    Products   p
JOIN    OrderItems oi   ON oi.product_id = p.id
JOIN    Orders     o    ON o.id = oi.order_id
WHERE   p.name ILIKE '%oracle%'
  AND   o.order_date BETWEEN '2024-01-01' AND '2024-12-31';

How to Calculate Oracle Pricing in PostgreSQL Syntax


SELECT  p.id,
        p.name,
        SUM(oi.quantity * p.price)        AS total_revenue,
        SUM(oi.quantity)                  AS total_units,
        SUM(oi.quantity * p.price)
        / NULLIF(SUM(oi.quantity),0)      AS avg_selling_price
FROM    Products       p
JOIN    OrderItems     oi ON oi.product_id = p.id
WHERE   p.name ILIKE '%oracle%'
GROUP BY p.id, p.name
ORDER BY total_revenue DESC;

Common Mistakes

Mistake: Summing <code>price</code> alone without multiplying by <code>quantity</code>. Fix: Always use <code>quantity * price</code> for revenue calculations.
Mistake: Forgetting to filter by product name with case-insensitive logic. Fix: Use <code>ILIKE '%oracle%'</code> or <code>LOWER(name) LIKE '%oracle%'</code>.

Frequently Asked Questions (FAQs)

How do I include discounts?

Add a discount column or subquery and subtract it in the revenue expression, e.g., (price - discount) * quantity.

Can I track pricing changes over time?

Store historical prices in a separate table or use price plus an effective_from column, then join on date ranges.

Why use NUMERIC instead of FLOAT for money?

NUMERIC keeps exact decimal precision, avoiding rounding issues common with floating-point types.
