A family of Microsoft relational database management systems designed for ease of use.
Show us one of those queries that didn't achieve your desired result. That is more helpful than simply saying it didn't work.
For example, this query should show the results you require.
SELECT Products.ID, Products.Name, Products.IsSeasonal, ShoppingList.N°, ShoppingList.QuantityToBuy
FROM Products INNER JOIN ShoppingList
ON Products.ID = ShoppingList.ProductID
Also, it would be helpful to explain where and how you want to use the query.
On a different topic. this is an unlikely choice for a field name in a table, N° and really should be changed.
In the Products and Recupes tables, the same is true of the field, Name. That should be ProductName, or RecipeName, or something similar. "Name" is is a reserved word in Access and should never be used for field names in user tables.
