我需要编写一个查询，为每条记录生成一种有序的ID ...例如：
ID Customer Name ------------------------- C1000 customer #1 C1010 customer #2 C1020 customer #3 C1030 customer #4
现在，这些“C1000”ID不存在......只有客户名称。我需要在选择时生成它们...所以我可以保存输出，然后导入到新系统中。
我该怎么做：
select
'C' + (some kinda code/math that generates the count based on a sequence? or row number?),
name
from Customers
=============================================== =
我最终执行了以下操作（因此我可以配置start＃和增量大小）：
DECLARE @start int;
DECLARE @inc int;
set @start = 1000;
set @inc = 10;
Select 'C' + CAST(@start + (@inc * (ROW_NUMBER() OVER (ORDER BY name))) as varchar) as NewID, Name
from customer
