Answer 1

Use JOIN as below to get desired output. Add o.total_amount in SELECT statement to return total_amount value.

CREATE PROCEDURE proc_assign_tier_for_rewards(
    @email varchar(255))
AS
BEGIN
    
    SELECT tier_name, 
           reward, 
           min_amount, 
           max_amount, 
           CONCAT(min_amount, '-', max_amount) AS range, 
           o.total_amount
    FROM reward_tier rt
    JOIN (SELECT SUM(total_amount) AS total_amount
           FROM dbo.orders
           WHERE company_email = @email
    ) o
        ON o.total_amount BETWEEN rt.min_amount AND rt.max_amount

END
