<prompt> Kuendesha SQL query kupata majina ya wateja ambao si kuweka amri yoyote.  <response>: As an AI language model, I dont have database access, but I can provide you a sample SQL query that you could use to find the names of customers who havent placed any orders. This query assumes that there are two tables: one named customers, with a column customer_name and a column customer_id, and another table named orders with a foreign key customer_id. Heres an example:sqlSELECT customer_name FROM customers WHERE customer_id NOT IN SELECT DISTINCT customer_id FROM ordersThis query selects the customer name from the customers table for customers whose customer IDs are not present in the orders table. Please note that for this query to work, you should have the database schema set up accordingly and the required data in it.
