How to join values from multiple rows in a single column? [duplicate]

I'm working on a project to find the association rule of items for Market dataset. I have a huge database that contains multi-tables. The output I got from this query

select sales_fact_1997.customer_id, sales_fact_1997.product_id,     
product.product_name
from sales_fact_1997 , product
where sales_fact_1997.product_id = product.product_id
group by sales_fact_1997.customer_id , sales_fact_1997.product_id
order by sales_fact_1997.customer_id, product.product_name;

is like that:

customer_id     product_id      product_name
13               1466           Hot Dogs
13               937            American Cole Slaw 
13               10             Akron City Map
...

Is there a way to get the output in this format:

customer_id     product_id      product_name
13              1466,937,10     Hot Dogs, American Cole Slaw, Akron City Map
