Is there a MySQL equivalent to PostgreSQL array_to_string

Question

I'm trying to find the MySQL equivalent of the PostgreSQL functions array and array_to_string and came across this post but asking for oracle9i which doesn't help me. I need to achieve this with MySQL but even Google can't seem to find any suitable answers.

So you don't have to read two posts, here is a repeat of the question:

In PostgreSQL, using the array and array_to_string functions can do the following:

Given the table "people":

id | name
---------
1  | bob
2  | alice
3  | jon

The SQL:

SELECT array_to_string(array(SELECT name FROM people), ',') AS names;

Will return:

names
-------------
bob,alice,jon

Anyone have any ideas how to achieve this in MySQL?

Answer 1

Try GROUP_CONCAT . e.g:

SELECT GROUP_CONCAT(name) AS names FROM people GROUP BY id;
