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
