如何将长VARCHAR文本拆分为每个单词一列

Question

我希望分手，例如'黑色花岗岩壁炉形状为54 x 26'，分别为单独的t-sql代码 - 不是复杂的逻辑。

with C1 as 
(
select ProductName, SUBSTRING(ProductName, 1, CHARINDEX(' ', ProductName))  as firstword,
SUBSTRING(ProductName, CHARINDEX(' ', ProductName), LEN(ProductName))  as secondword
from [dbo].[AProducts]
),
C2 AS 
(
select firstword, secondword
from C1
)

select firstword, SUBSTRING(secondword, 1, CHARINDEX(' ', secondword)) as z from C2

这是PRODUCTNAME EXTRACT：

To credit against Invoice 104 - overcharged in error
Black Granite Hearth to t-shape, 54 x 26
Black Granite Header 38 x 5, Slips 32 x 5
Nero Zimbabwe 30mm worktops, supplied and fitted

Answer 1

奇怪的要求横向与纵向相对。如果没有动态，你就会冒着丢失文字的风险，但如果有必要，以下内容很容易扩展。

示例

Declare @YourTable table (PRODUCTNAME varchar(max))
Insert Into @YourTable values
 ('To credit against Invoice 104 - overcharged in error')
,('Black Granite Hearth to t-shape, 54 x 26')
,('Black Granite Header 38 x 5, Slips 32 x 5')
,('Nero Zimbabwe 30mm worktops, supplied and fitted')

Select A.*
      ,C.*
 From  @YourTable A
 Cross Apply ( Select CleanString = replace(replace(replace(A.ProductName,' x ','x'),',',''),' - ',' ') ) B
 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)')))
                      ,Pos8  = ltrim(rtrim(xDim.value('/x[8]' ,'varchar(max)')))
                      ,Pos9  = ltrim(rtrim(xDim.value('/x[9]' ,'varchar(max)')))
                From  (Select Cast('<x>' + replace((Select replace(B.CleanString,' ','§§Split§§') as [*] For XML Path('')),'§§Split§§','</x><x>')+'</x>' as xml) as xDim) as X
             ) C
