JSON_ARRAYAGG in SQL Server - Examples & AI Generator

Working with JSON_ARRAYAGG in SQL Server can be tricky, especially if you’re used to other databases like MySQL or PostgreSQL where it’s natively supported. In SQL Server, creating JSON arrays from grouped data often requires advanced syntax or custom workarounds. AI2sql eliminates coding guesswork, letting you generate complex JSON_ARRAYAGG queries with plain-language prompts — no manual memorization or debugging needed.

JSON_ARRAYAGG Syntax in SQL Server

Unlike databases with built-in JSON_ARRAYAGG, SQL Server uses a combination of FOR JSON and aggregate string functions to mimic similar behavior. Here’s a typical pattern:

SELECT [GroupColumn],
  (SELECT [ValueColumn]
   FROM [Table] t2
   WHERE t2.[GroupColumn]=t1.[GroupColumn]
   FOR JSON PATH) AS AggregatedArray
FROM [Table] t1
GROUP BY [GroupColumn];

  • FOR JSON PATH: Converts selected rows into a JSON array.

  • GROUP BY: Defines how items are grouped before aggregation.

JSON_ARRAYAGG Examples You Can Generate Instantly

1. Aggregate Products for Each Order

SELECT o.OrderID,
  (SELECT p.ProductName
     FROM OrderDetails od
     JOIN Products p ON od.ProductID = p.ProductID
     WHERE od.OrderID = o.OrderID
     FOR JSON PATH) AS ProductsJSON
FROM Orders o;

2. List All Orders Placed by a Customer as JSON Array

SELECT c.CustomerName,
  (SELECT o.OrderID
     FROM Orders o
     WHERE o.CustomerID = c.CustomerID
     FOR JSON PATH) AS OrdersJSON
FROM Customers c;

3. Gather Employee Emails by Department

SELECT Department,
  (SELECT Email
     FROM Employees e2
     WHERE e2.Department = e1.Department
     FOR JSON PATH) AS EmailsJSON
FROM Employees e1
GROUP BY Department;

FAQ: JSON_ARRAYAGG in SQL Server

Does SQL Server support JSON_ARRAYAGG natively?

No, SQL Server does not have a native JSON_ARRAYAGG function. You achieve the same result using FOR JSON PATH with subqueries and aggregation.

When should I use JSON_ARRAYAGG patterns in SQL Server?

Anytime you need to return grouped JSON arrays (like product lists, emails, or orders) in your SQL Server apps or APIs.

How can AI SQL generators save me time?

AI2sql instantly produces complex JSON aggregation queries from natural language prompts, saving hours compared to hand-writing the logic for each business scenario.
