PIVOT in PostgreSQL - Examples & AI Generator

Pivoting data in PostgreSQL is an advanced SQL task that often requires complex expressions or CASE WHEN and GROUP BY logic, since PostgreSQL does not offer a native PIVOT operator. For many SQL developers and analysts, memorizing the right syntax for each RDBMS is time-consuming. AI2sql solves this in seconds—simply describe your pivot requirement in plain English and get a ready-to-run query, no manual coding or syntactic nuances required.

PIVOT Syntax in PostgreSQL

PIVOT transformations in PostgreSQL are typically achieved using CASE expressions combined with GROUP BY. Unlike SQL Server's dedicated PIVOT clause, here's the general approach:

SELECT
  group_column,
  SUM(CASE WHEN pivot_column = 'Value1' THEN data_column ELSE 0 END) AS value1_total,
  SUM(CASE WHEN pivot_column = 'Value2' THEN data_column ELSE 0 END) AS value2_total,
  ...
FROM source_table
GROUP BY group_column;

PIVOT Examples You Can Generate Instantly

Below are real-world PIVOT PostgreSQL examples you can copy, adapt, and run. Each example demonstrates a use case you can automate with AI2sql in 10 seconds or less.

1. Sales by Quarter for Each Product

SELECT
  product_id,
  SUM(CASE WHEN quarter = 'Q1' THEN amount ELSE 0 END) AS q1_sales,
  SUM(CASE WHEN quarter = 'Q2' THEN amount ELSE 0 END) AS q2_sales,
  SUM(CASE WHEN quarter = 'Q3' THEN amount ELSE 0 END) AS q3_sales,
  SUM(CASE WHEN quarter = 'Q4' THEN amount ELSE 0 END) AS q4_sales
FROM sales
GROUP BY product_id;

2. Count of Orders per Status

SELECT
  customer_id,
  COUNT(CASE WHEN status = 'Pending' THEN 1 END) AS pending_orders,
  COUNT(CASE WHEN status = 'Shipped' THEN 1 END) AS shipped_orders,
  COUNT(CASE WHEN status = 'Cancelled' THEN 1 END) AS cancelled_orders
FROM orders
GROUP BY customer_id;

3. Monthly User Registrations by Region

SELECT
  region,
  COUNT(CASE WHEN EXTRACT(MONTH FROM registered_at) = 1 THEN user_id END) AS jan_registrations,
  COUNT(CASE WHEN EXTRACT(MONTH FROM registered_at) = 2 THEN user_id END) AS feb_registrations,
  COUNT(CASE WHEN EXTRACT(MONTH FROM registered_at) = 3 THEN user_id END) AS mar_registrations
FROM users
GROUP BY region;

Frequently Asked Questions

Does PostgreSQL support a native PIVOT function?

No, PostgreSQL does not have a built-in PIVOT function like SQL Server. Pivoting is achieved using CASE statements with GROUP BY.

Can I automate PIVOT queries without SQL knowledge?

Yes, with AI SQL generators like AI2sql, you can instantly transform plain-language prompts into optimized PostgreSQL PIVOT queries.

Is AI2sql suitable for advanced PIVOT use cases?

Absolutely. AI2sql generates advanced, production-ready queries for even the most complex multi-dimensional pivots in 10 seconds.
