Splitting a SQL column's value into several fields - sql

Question

I have a bunch of rows that have a field called "name" that have values like this, delimited by a _:
ServerNumber_BrandNumber_BrandName_JobName
Sometimes, the job name will be spread out over two deliminations, like this:
ServerNumber_BrandNumber_BrandName_JobName_JobNamePart2
I want to break out each of those into their own field in a select statement like this:
SELECT
name[0] as ServerNumber,
name[1] as BrandNumber,
name[2] as BrandName,
name[3] as JobName
from table
If I do something like this it will work if job name is only part of one delmiter, but it will return nothing if it's using two:
REVERSE(PARSENAME(REPLACE(REVERSE(name), '_', '.'), 1))
How can I do all of this?

Answer 1

Working example
Declare #YourTable Table ([Name] varchar(150)) Insert Into #YourTable Values
('ServerNumber_BrandNumber_BrandName_JobName')
,('ServerNumber_BrandNumber_BrandName_JobName_JobNamePart2')
Select Pos1 = JSON_VALUE(JS,'$[0]')
,Pos2 = JSON_VALUE(JS,'$[1]')
,Pos3 = JSON_VALUE(JS,'$[2]')
,Pos4 = concat(JSON_VALUE(JS,'$[3]'),'_'+JSON_VALUE(JS,'$[4]'))
From #YourTable A
Cross Apply (values ('["'+replace(replace(string_escape([Name],'json'),' ','_'),'_','","')+'"]') ) B(JS)
Results
Pos1 Pos2 Pos3 Pos4
ServerNumber BrandNumber BrandName JobName
ServerNumber BrandNumber BrandName JobName_JobNamePart2
XML Approach (2012)
Select Pos1 = xDim.value('/x[1]','varchar(150)')
,Pos2 = xDim.value('/x[2]','varchar(150)')
,Pos3 = xDim.value('/x[3]','varchar(150)')
,Pos4 = concat(xDim.value('/x[4]','varchar(150)'),'_'+xDim.value('/x[5]','varchar(150)'))
From #YourTable A
Cross Apply ( values (cast('<x>' + replace((Select replace(NAME,'_','§§Split§§') as [*] For XML Path('')),'§§Split§§','</x><x>')+'</x>' as xml))) B(xDim)
