LISTAGG in MySQL - Examples & AI Generator

While the LISTAGG function standardizes value aggregation into a single comma-separated list in many databases, MySQL doesn’t support LISTAGG natively. Replicating its behavior often means writing complex GROUP_CONCAT queries or remembering subtle differences in MySQL syntax. For data professionals working across systems, this can be a time-consuming hurdle.

AI2sql eliminates this barrier by turning natural language requests into production-ready, copy-paste MySQL queries—no manual coding required. Skip memorizing MySQL LISTAGG workarounds and generate what you need in seconds.

LISTAGG Syntax in MySQL

Since MySQL lacks a built-in LISTAGG function, its closest equivalent is GROUP_CONCAT. Here’s the main pattern:

SELECT column1, GROUP_CONCAT(column2 ORDER BY column2 SEPARATOR ',') AS aggregated_list
FROM table_name
GROUP BY column1;

  • GROUP_CONCAT(): Aggregates values into a single string.

  • ORDER BY: (optional) Set sort order of concatenated values.

  • SEPARATOR: Define the delimiter (default is comma).

Note: Maximum length is controlled by group_concat_max_len session variable.

LISTAGG Examples You Can Generate Instantly

1. List product names per order (e.g., e-commerce sales report)

SELECT order_id, GROUP_CONCAT(product_name ORDER BY product_name) AS products
FROM order_details
GROUP BY order_id;

2. Aggregate customer emails by region (e.g., marketing campaign)

SELECT region, GROUP_CONCAT(email SEPARATOR '; ') AS customer_emails
FROM customers
GROUP BY region;

3. Combine employee skills by department (e.g., HR overview)

SELECT department_id, GROUP_CONCAT(skill ORDER BY skill SEPARATOR ', ') AS skills
FROM employee_skills
GROUP BY department_id;

FAQ: LISTAGG in MySQL

Does MySQL have a native LISTAGG function?

No, MySQL does not implement a native LISTAGG function. Use GROUP_CONCAT() to achieve similar results.

How do I change the separator in MySQL’s GROUP_CONCAT?

You can specify a custom separator using: GROUP_CONCAT(column SEPARATOR '; ')

Is there a limit to GROUP_CONCAT in MySQL?

Yes, the result length is limited by group_concat_max_len. You can change it by running SET SESSION group_concat_max_len = [value];
