Question

我试图查询客户当前的产品价格表。每个客户记录最多有3个价格代码。 Price_code是第一个价格。如果某个项目不在该列表上或价格已过期，则系统会查看Price_code_2，然后是Price_code_3。除此之外，每个客户都可以拥有一个覆盖所有3个价格代码的客户部件记录。我曾为客户部分记录和price_code条目工作的查询，但忽略了price_code_2和price_code_3。以下示例中的客户具有所有3个价格代码的客户部件定价和值。

declare @Customer as varchar(8)
    , @Today as date

set @Customer = 'tre001'
set @Today = GETDATE()

奇怪的表格设计...您在上面写的查询意味着当有效期不同时，价格代码也会发生变化。无论如何，问题是 SOFCM.PRICE_CODE，SOFCM.PRICE_CODE_2，SOFCM.PRICE_CODE_3始终返回NOT NULL。请检查PC1.PRICE_CODE，PC2.PRICE_CODE，PC3.PRICE_CODE。现在，您想首先评估quote_unit_price吗？也许它有效。
