Question

您好我的批量插入问题。
挑战/目标是将具有逗号分隔符的列保存到具有不同ID's的另一个表例如 - ＆gt;
我从@temp table

中选择了查询

Rolln FullName
  441246 John Doe，Jane More，John Spade
  441248 Jose Mendez，Ali Muhm，Jacob Stile

保存在人员表中结果将在插入People-＆gt;

之后

People_ID RollNumber FullName
  1 441246 John Doe
  2 441246简更多
  3 441246约翰·斯佩德

我创建的脚本重复名称为

INSERT @Temp_Original
select rollnumber,
case when CHARINDEX(',',FullName)>0 
     then SUBSTRING(FullName,1,CHARINDEX(',',FullName)-1) 
     else FullName end FullName, 
CASE WHEN CHARINDEX(',',FullName)>0 
     THEN REPLACE(SUBSTRING(FullName,CHARINDEX(',',FullName)+1,len(FullName)), ',', '') 
     ELSE NULL END as FullName2,
 CASE WHEN CHARINDEX(',',FullName)>0 
     THEN REPLACE(SUBSTRING(FullName,CHARINDEX(',',FullName)+1,len(FullName)), ',', '')  
     ELSE NULL END as FullName3,
[Address], Code, Place, [Country], LegalTxt
from (
select newrec.RollNumber, newrec.FullName, newrec.[Address], newrec.Code, newrec.Place, newrec.Country, newrec.LegalTxt
 from [dbo].[view_FinanceCompare] newrec
left join [dbo].[view_MainCompare] oldrec
on newrec.RollNumber = oldrec.rollnumber
where  oldrec.rollnumber is null
) t



--Print 'Insert to people'
Insert [dbo].[dbo_People] ([FullName], [CreatedOn], [CreatedBy])
Select Fullname, getdate(), rollnumber
From @Temp_Original
UNION 
Select Fullname2, getdate(), rollnumber
From @Temp_Original Where FullName2<>''
UNION 
Select Fullname3, getdate(), rollnumber
From @Temp_Original Where FullName3<>''

你可以用递归cte来做。这是一个例子：

create table t(id int, n nvarchar(max))
Insert into t values
(1, 'a,b,c'),
(2, 'e,f,g')

; with cte as (
  Select 
  Id,
  N,
  substring(n, 1, charindex(',', n)-1) as name,
  Charindex(',',n) as p
  From t

  Union all

  Select id, n, substring(n, p+1, charindex(',', n, p)-1),
  Charindex(',', n, p+1)
  From cte
  Where p <> 0
)

Select id, namename from cte
Order by id, name

使用逗号分隔符插入数据但具有不同的ID
