LISTAGG in SQL Server - Examples & AI Generator

Working with string aggregation across rows—commonly known as LISTAGG—isn’t straightforward in SQL Server. SQL developers often need to switch mental gears between databases, learning different string aggregation functions for Oracle, PostgreSQL, or SQL Server. Instead of memorizing complex syntax or custom workarounds, you can now generate production-ready LISTAGG queries in 10 seconds with AI2sql. Zero coding, instant results—especially useful for developers and analysts managing multi-platform workloads.

LISTAGG Syntax in SQL Server

Unlike Oracle, SQL Server doesn’t have a direct LISTAGG function. Instead, use a combination of STRING_AGG() (available from SQL Server 2017+) to concatenate values, or employ FOR XML PATH in older versions.

Latest SQL Server LISTAGG Syntax

SELECT column1, STRING_AGG(column2, ', ') AS AggregatedList
FROM tablename
GROUP BY column1;

  • STRING_AGG is the SQL Server equivalent for LISTAGG.

  • GROUP BY determines the grouping key.

  • Customize the delimiter as needed (e.g., ’, ’, ’|’).

LISTAGG Examples You Can Generate Instantly

Here are copy-paste-ready LISTAGG SQL Server examples for real business scenarios. Simply adapt fields/tables—or generate your custom query with AI2sql in seconds:

1. Customer Orders by Customer

SELECT 
  CustomerID, 
  STRING_AGG(OrderID, ', ') AS OrdersList
FROM Orders
GROUP BY CustomerID;

2. Product Names by Category

SELECT 
  CategoryName, 
  STRING_AGG(ProductName, ' | ') AS Products
FROM Products
GROUP BY CategoryName;

3. Employee Skills by Department

SELECT 
  Department, 
  STRING_AGG(Skill, '; ') AS SkillSet
FROM EmployeeSkills
GROUP BY Department;

FAQ: LISTAGG in SQL Server

Is LISTAGG available in SQL Server?

LISTAGG is not a direct function in SQL Server. Use STRING_AGG() from SQL Server 2017 onwards, or FOR XML PATH in older versions.

How do I control the order in a LISTAGG result?

Add an ORDER BY within STRING_AGG() if SQL Server version supports it:
STRING_AGG(column, ', ') WITHIN GROUP (ORDER BY another_column)

Can I customize the separator?

Yes, specify any delimiter as the second parameter (e.g., ”, ”, ”; ”, ”|”) in STRING_AGG().
