我有以下情况，我有一个客户在我的数据库上他购买了特定的信息组合，我的意思是，目前该表显示了客户的名称，类别，地点，年份，国家，C1，C2 ，交付，频率和一个例子看起来像这样。
Customer Categ Place YM Country C1 C2 delivery Frequency
ALB Clock WM 201609 France 1 1 name Trimestral- 3,6,9,12
ALB car NewE 201610 Spain 1 0 Trimestral- 3,6,9,12
ALC TV AWS 201611 Guate 1 0 Trimestral- 3,6,9,12
ALB smart Eb 201612 Japan 1 1 Trimestral- 3,6,9,12
有时交货有名称和其他一些它不会取决于客户也C2取决于频率，它与YM有关。
让我们说如果频率是三分之一的话，那么当月份是3/6/9/12时我需要C2为1但是我必须选择从201701到201712生成值，而另一个只生成值时它是201703/201706等等。
所有这些价值将使用当年的最后四个月生成。
如果您有任何疑问，请告诉我，因为我知道这有点棘手
我正在使用案例句子，但它是复制组合，我的意思是创建一行c2 = 1和c2 = 0
Customer Categ Place YM Country C1 C2 delivery Frequency
ALB Clock WM 201609 France 1 1 name Trimestral- 3,6,9,12

也许是因为我想生成独特的价值观，并且不知道如何帮助或建议如何做到这一点。

使用测试数据进行了更新
我认为在与生成的值进行交叉连接之前，您需要从db.dbo.Prod获取不同的行。
您可能还有Trimestral I次，而不是Trimestral II，请参阅下面的代码。
你的案例陈述也可以稍微优化一下，如下：
Rextester：Update-FormatData
create table Prod (Customer varchar(32),Categ varchar(32),Place varchar(32),YM int,Country varchar(32),C1 int,delivery varchar(32),Frequency varchar(32));
insert into Prod (Customer,Categ,Place,YM,Country,C1,delivery,Frequency) values
