Join MYSQL tables and sort by two fields?

I'm having a problem sorting my tables in MYSQL.

I have my tables setup like this:

Order_details

• Order_ID
• shipping_cost
• printed

Product_details

• ID
• Order_ID
• SKU_location

I want to SELECT all orders WHERE printed = FALSE but also sort by the shipping costs and THEN by the SKU_location

How can I join the tables into one query s开发者_如何学JAVAo it sorts by shipping_cost and SKU_location where printed = false?

You can do an implicit JOIN in the following way:

SELECT * 
FROM Order_details od
JOIN Product_details pd
ON od.Order_ID = pd.Order_ID
WHERE od.printed = FALSE
ORDER BY od.shipping_cost, pd.SKU_location

The text following each table renames the table for easy reference in the later parts of the query (i.e. the code "Database.Long_Table_Name ltn" renames the table to "ltn")
