从 SQL Server 表中的带连字符的字符串列中提取第 1 个第 2 个第 3 个值直到第 n 个值

Question

Table has values like 12-43-5765-234-56-24-6456-234-678-9-0-0 with hyphens

I need to take the first value as a separate column and 2nd value as separate column and so on.

I tried like this.

DECLARE @S VARCHAR(MAX);
SET @S = '12-43-5765-234-56-24-6456-234-678-9-0-0'

SELECT SUBSTRING(@S, 0, CHARINDEX('-', @S)) AS first

This above query selects only first value, but how can 4th and fifth value can be extracted from string? like

12 as first,
43 as second,
5765 as third,
234 as fourth,
56 as fifth,
24 as sixth and so on..

Answer 1

If you have a maximum (or known) number of positions, and DON'T want to go dynamic

Example

DECLARE @S VARCHAR(MAX);
SET @S='12-43-5765-234-56-24-6456-234-678-9-0-0'


Select Pos1 = xDim.value('/x[1]','varchar(max)') --could change to desired datatype (int ?)
      ,Pos2 = xDim.value('/x[2]','varchar(max)') 
      ,Pos3 = xDim.value('/x[3]','varchar(max)')
      ,Pos4 = xDim.value('/x[4]','varchar(max)')
      ,Pos5 = xDim.value('/x[5]','varchar(max)')
      ,Pos6 = xDim.value('/x[6]','varchar(max)')
      ,Pos7 = xDim.value('/x[7]','varchar(max)')
      ,Pos8 = xDim.value('/x[8]','varchar(max)')
      ,Pos9 = xDim.value('/x[9]','varchar(max)')
      ,Pos10= xDim.value('/x[10]','varchar(max)')
      ,Pos11= xDim.value('/x[11]','varchar(max)')
      ,Pos12= xDim.value('/x[12]','varchar(max)')
      ,Pos13= xDim.value('/x[13]','varchar(max)')
 From  (Select Cast('<x>' + replace(@S,'-','</x><x>')+'</x>' as xml) as xDim) as A 

Returns
