hi

I have a warehouse_products table which defines how many products in the warehouses

so lets say I have 20 records/rows in the table, some rows may contain the same product id but in a different warehouse

I need to create select statement that give every product one row, and in this row I must have the quantity in warehouse A and warehouse B ..

so in the end I will get for example 10 rows that contain all the data

 id  domain_id   warehouse_id  wh_product_id  quantity

2 1 2 2 84
3 1 1 3 221
4 1 3 3 0 5 1 1 3 14 6 1 1 2 73 7 1 1 1 123
