Question

我有一个表格，其内容字段填充了该页面上的项目ID。像这样：

ID                | Contents
Section-page-id   |  item-1 item-2 item-3 item-4 item-5
Section-page-id2  |  item-6 item-7 item-8 item-9 item-10

我想创建一个如下所示的临时表：

Section-id       |ID
item-1           |Section-page-id 
item-2           |Section-page-id 
item-3           |Section-page-id 
item-4           |Section-page-id 
item-5           |Section-page-id 
item-6           |Section-page-id2 
item-7           |Section-page-id2 
item-8           |Section-page-id2 
item-9           |Section-page-id2 
item-10          |Section-page-id2

这甚至可能吗？提前感谢您的时间。

来自Turning a Comma Separated string into individual rows：

Declare @YourTable table
(
ID varchar(50),
Contents varchar(max)
)
Insert Into @YourTable values
('Section-page-id','item-1 item-2 item-3 item-4 item-5'),
('Section-page-id2','item-6 item-7 item-8 item-9 item-10')


;WITH CTE (ID, SectionId, Contents)  as (

select ID, LEFT(Contents, CHARINDEX(' ',Contents+' ')-1),
    STUFF(Contents, 1, CHARINDEX(' ',Contents+' '), '')
from @YourTable
union all
select ID, LEFT(Contents, CHARINDEX(' ',Contents+' ')-1),
    STUFF(Contents, 1, CHARINDEX(' ',Contents+' '), '')
from CTE
where Contents > ''
)
select SectionId, ID
from CTE
order by ID
