SQL逗号将参数中的值分隔为单独的行

Question

SQL问题

对于存储过程输入,例如:

• @CustomerID ='1,2,3,4,'
• @Address ='Oregon'
• @City ='波特兰'

.我需要将值插入到单独的行中,如下所示:

    customerID | address city
 --------------+------------------
    1          |  Oregon Portland
    2          |  Oregon Portland
    3          |  Oregon Portland
    4          |  Oregon Portland

我需要有关如何在单个参数中插入CSV值以分隔行的帮助.

Answer 1

使用Jeff Moden的CSV分离器功能:

declare @CustomerId varchar(8000) = '1,2,3,4,'
      , @Address    varchar(64)   = 'Oregon' 
      , @City       varchar(64)   = 'Portland'

select 
    CustomerId = d.Item
  , Address = @Address
  , City = @City
from [dbo].[delimitedsplit8K](@CustomerId,',') as d
where d.Item <> ''

收益:

+------------+---------+----------+
| CustomerId | Address |   City   |
+------------+---------+----------+
|          1 | Oregon  | Portland |
|          2 | Oregon  | Portland |
|          3 | Oregon  | Portland |
|          4 | Oregon  | Portland |
+------------+---------+----------+
