使用存储过程基于最大ID获取数据

Question

存储过程返回最新的客户ID。

通过传递两个变量返回最新的客户ID。在这种情况下，一个变量是单元号，另一个是设施策略号。

再次感谢你们！

CREATE PROCEDURE [dbo].[Getcustomerinfo] (@UN  VARCHAR(20), 
                                          @FPN VARCHAR(20)) 
AS `enter code here`
  BEGIN 
      SELECT customers.id, 
             customers.full_name,
