处理通过laravel中的join获取的重复行

Question

I have two tables

 1-products
 --------
 product_id
 product_name

 2-product_images
 --------------
 image_id
 product_id
 product_image

Now I have multiple images for one product. Means there are multiple records for in product_images table for single product_id.

When I execute this query

 $products = Product::join('product_images AS pi', 'pi.product_id', 'products.product_id')
 ->get();

This results in getting multiple rows for same product due to join. Now how do I handle that in spite of many images for single product, just one row should be fetched or shown. I can do it through Laravel but I want to learn handling through database. If can, help.

Answer 1

->groupBy('products.product_id')
