SELECT select_list 
   FROM table_source 
   WHERE search_condition
   GROUP BY group_by_expression 
   HAVING search_condition
   ORDER BY order_by_expression

Here is an example of a SELECT statement with all clauses mentioned above:

SELECT SalesOrderID, SUM(LineTotal) AS TotalPrice
   FROM SalesLT.SalesOrderDetail
   WHERE ModifiedDate > '2004-05-01'
   GROUP BY SalesOrderID
   HAVING COUNT(*) > 30
   ORDER BY TotalPrice DESC
