Разделете стойността на една колона на няколко стойности на колони

Ето един вграден подход

Пример

Declare @YourTable table (SomeCol varchar(max))
Insert Into @YourTable values
('SC 5-1395-174-25P'),
('SC 1-2134-123-ABC C1-2'),
('SC 12-5245-1247-14&P'),
('SC ABCD-2525-120')


Select B.*
 From  @YourTable A
 Cross Apply (
                Select Pos1 = ltrim(rtrim(xDim.value('/x[1]','varchar(max)')))
                      ,Pos2 = ltrim(rtrim(xDim.value('/x[2]','varchar(max)')))
                      ,Pos3 = ltrim(rtrim(xDim.value('/x[3]','varchar(max)')))
                      ,Pos4 = ltrim(rtrim(xDim.value('/x[4]','varchar(max)')))
                      ,Pos5 = ltrim(rtrim(xDim.value('/x[5]','varchar(max)')))
                      ,Pos6 = ltrim(rtrim(xDim.value('/x[6]','varchar(max)')))
                      ,Pos7 = ltrim(rtrim(xDim.value('/x[7]','varchar(max)')))
                From  (Select Cast('<x>' + replace((Select replace(replace(A.SomeCol,' ','-'),'-','§§Split§§') as [*] For XML Path('')),'§§Split§§','</x><x>')+'</x>' as xml) as xDim) as A

1) Създайте своята таблица

CREATE TABLE MyNewPubTable (PUB_FORM_NUM NVARCHAR(50) , COL1 NVARCHAR(10) , COL2 NVARCHAR(10) , COL3 NVARCHAR(10) , COL4 NVARCHAR(10) , COL5 NVARCHAR(10) , COL6 NVARCHAR(10) , COL7 NVARCHAR(10)) 

2) Изпълнете заявката

Declare @YourTable table (PUB_FORM_NUM varchar(max))
Insert Into @YourTable values
('SC 5-1395-174-25P'),
('SC 1-2134-123-ABC C1-2'),
('SC 12-5245-1247-14&P'),
('SC ABCD-2525-120')

Insert Into MyNewPubTable
Select A.PUB_FORM_NUM
      ,B.*
 From  @YourTable A
 Cross Apply (
                Select Pos1 = ltrim(rtrim(xDim.value('/x[1]','varchar(max)')))
                      ,Pos2 = ltrim(rtrim(xDim.value('/x[2]','varchar(max)')))
                      ,Pos3 = ltrim(rtrim(xDim.value('/x[3]','varchar(max)')))
                      ,Pos4 = ltrim(rtrim(xDim.value('/x[4]','varchar(max)')))
                      ,Pos5 = ltrim(rtrim(xDim.value('/x[5]','varchar(max)')))
                      ,Pos6 = ltrim(rtrim(xDim.value('/x[6]','varchar(max)')))

('SC 1-2134-123-ABC C1-2'),
('SC 12-5245-1247-14&P'),
('SC ABCD-2525-120')

Select A.PUB_FORM_NUM
      ,B.*
 Into  MyNewPubTable
 From  @YourTable A
 Cross Apply (
                Select Pos1 = ltrim(rtrim(xDim.value('/x[1]','varchar(max)')))
                      ,Pos2 = ltrim(rtrim(xDim.value('/x[2]','varchar(max)')))
