我知道有一个SQL:
样本表:
ID FirstName LastName
1 Jones Smith
2 Paul Tabunjong
3 John Parks
SQL结果:
ID Name
1 Jones Smith
2 Paul Tabunjong
3 John Parks
现在,有可能扭转它吗?像这样的东西:
样本表:
ID Name
1 Jones Smith
2 Paul Tabunjong
3 John Parks
SQL结果:
ID FirstName LastName
1 Jones Smith
2 Paul Tabunjong
3 John Parks
另一个:是否有可能有这样的事情:
样本表:
ID CorporateNames
1 Jones Smith; Anna Tomson; Tonny Parker
2 Paul Tabunjong; Poncho Pilato
3 John Parks; Berto Taborjakol
SQL结果:
ID FirstName LastName
1 Jones Smith
1 Anna Tomson
1 Tonny Parker
2 Paul Tabunjong
2 Poncho Pilato
3 John Parks
3 Berto Taborjakol

是的,您可以编写拆分功能,然后使用它来解析数据。下面是使用SUBSTRING()函数的示例拆分函数:
CREATE FUNCTION dbo.Split
(
@RowData nvarchar(2000),
@SplitOn nvarchar(5)
)
RETURNS @RtnValue table
(
Id int identity(1,1),
Data nvarchar(100)
)
AS
BEGIN
Declare @Cnt int
Set @Cnt = 1
While (Charindex(@SplitOn,@RowData)>0)
Begin
Insert Into @RtnValue (data)
Select
Data = ltrim(rtrim(Substring(@RowData,1,Charindex(@SplitOn,@RowData)-1)))
Set @RowData = Substring(@RowData,Charindex(@SplitOn,@RowData)+1,len(@RowData))
Set @Cnt = @Cnt + 1
End
Insert Into @RtnValue (data)
Select Data = ltrim(rtrim(@RowData))
Return
END
