 ### Query Practice
 
 Write SQL queries to complete the following tasks:
 
-- [ ] List all the products whose name contains the word "socks"
-- [ ] List all the products which cost more than 100 showing product id, name, unit price, and supplier id
-- [ ] List the 5 most expensive products
-- [ ] List all the products sold by suppliers based in the United Kingdom. The result should only contain the columns product_name and supplier_name
-- [ ] List all orders, including order items, from customer named Hope Crosby
-- [ ] List all the products in the order ORD006. The result should only contain the columns product_name, unit_price, and quantity
-- [ ] List all the products with their supplier for all orders of all customers. The result should only contain the columns name (from customer), order_reference, order_date, product_name, supplier_name, and quantity
+- [x] List all the products whose name contains the word "socks"
+
+```sql
+    select * from products where product_name like '%sock%';
+
+    -- producing all the names in product table containing 'sock'
+```
+
+- [x] List all the products which cost more than 100 showing product id, name, unit price, and supplier id
+
+```sql
+    select pv.prod_id , p.product_name ,pv.supp_id,sp.supplier_name , pv.unit_price from product_availability pv join products p on (pv.prod_id=p.id) join suppliers sp on(sp.id=pv.supp_id)  where unit_price>100;
+
+    -- the query shows the product id , its name , supplier id and supplier name , along side the unit_price .
+```
+
+- [x] List the 5 most expensive products
+
+```sql
+select * from product_availability order by unit_price desc limit 5;
+-- the query order unit_pric descending and limit results to first 5 items.
+
+```
+
+- [x] List all the products sold by suppliers based in the United Kingdom. The result should only contain the columns product_name and supplier_name
+
+```sql
+    select p.product_name ,sp.supplier_name  from order_items o join products p on (o.product_id=p.id) join suppliers sp on (o.supplier_id=sp.id) where sp.country='United Kingdom';
+    -- Query retrieves rpoduct name and supp name from other tables using join
+```
+
+- [x] List all orders, including order items, from customer named Hope Crosby
+
+```sql
+    select o.id,o.order_date,o.order_reference ,cu.name,pr.product_name from orders o join order_items oi on (o.id=oi.order_id) join customers cu on (o.customer_id=cu.id) join products pr on (oi.product_id=pr.id)  where name='Hope Crosby';
+    -- This query connects 4 tabels but it returns only order id  order_date , order_reference , customer name and product name.
+```
+
+- [x] List all the products in the order ORD006. The result should only contain the columns product_name, unit_price, and quantity
+
+```sql
+    select pr.product_name, oi.quantity,sp.supplier_name from orders o join order_items oi on (o.id=oi.order_id) join suppliers sp on (oi.supplier_id=sp.id) join products pr on (pr.id=oi.product_id) where order_reference='ORD006';
+```
+
+- [x] List all the products with their supplier for all orders of all customers. The result should only contain the columns name (from customer), order_reference, order_date, product_name, supplier_name, and quantity
+
+```sql
+    select cu.name , o.order_reference , o.order_date,pr.product_name , sp.supplier_name , oi.quantity from orders o join customers cu on (o.customer_id=cu.id) join order_items oi on(oi.order_id=o.id) join products pr on(oi.product_id=pr.id) join suppliers sp on (oi.supplier_id=sp.id) ;
+```
