An Easy Way to Split multiple String using Transact-SQL - sql-server

Question

I have 3 strings
#NameList = Hi|Hi1|Hi2
#DESCLIST = Hii|Hii1|Hii2
#SEQList = 1|2|3
I am looking for a Transact-SQL function where it can split these strings and insert in to table in below order
pkid Name DESC Seq
1 Hi Hii 1
2 Hi1 Hii1 2
3 Hi2 Hii2 3

Answer 1

As Martin Smith suggested, you just need to use a string splitting function and join the results together:
declare #NameList nvarchar(100) = 'Hi|Hi1|Hi2';
declare #DESCLIST nvarchar(100) = 'Hii|Hii1|Hii2';
declare #SEQList nvarchar(100) = '1|2|3';
select s1.item as Name
,s2.item as [Desc]
,s3.item as Seq
from dbo.fn_StringSplit(#NameList,'|',null) as s1
join dbo.fn_StringSplit(#DESCLIST,'|',null) as s2
on s1.rn = s2.rn
join dbo.fn_StringSplit(#SEQList,'|',null) as s3
on s1.rn = s3.rn;
Results:
+------+------+------+-----+
| pkid | Name | Desc | Seq |
+------+------+------+-----+
| 1 | Hi | Hii | 1 |
| 2 | Hi1 | Hii1 | 2 |
| 3 | Hi2 | Hii2 | 3 |
+------+------+------+-----+
String Split Function:
create function [dbo].[fn_StringSplit]
(
#str nvarchar(max) = ' ' -- String to split.
,#delimiter as nvarchar(255) = ',' -- Delimiting value to split on.
,#num as int = null -- Which value to return, null returns all.
)
returns table
as
return
(
with d as
(
select rn = row_number() over (order by (select null))
,item = y.i.value('(./text())[1]', 'nvarchar(max)')
from(select x = convert(xml, '<i>'
+ replace((select #str for xml path('')), #delimiter, '</i><i>')
+ '</i>'
).query('.')
) AS a
cross apply x.nodes('i') AS y(i)
)
select rn
,item
from d
where rn = #num
or #num is null
);

I would use the function:
STRING_SPLIT (string, separator)
with table values that divides a string into rows of substrings, according to a specified separator character and would return the records by assigning them an id through the Row_number function that returns a sequential number to each row within a partition of a result set:
DECLARE #NameList VARCHAR(50) = 'Hi|Hi1|Hi2'
DECLARE #DESCLIST VARCHAR(50) = 'Hii|Hii1|Hii2'
DECLARE #SEQList VARCHAR(50) = '1|2|3'
select namelist.name,DESCLIST.descr, SEQList.SEQ from
(select value as name ,row_number() over (order by (select null)) as id from STRING_SPLIT(#NameList,'|') )
namelist inner join
(select value as descr ,row_number() over (order by (select null)) as id from STRING_SPLIT(#DESCLIST,'|') )
DESCLIST on namelist.id = DESCLIST.id inner join
(select value as SEQ ,row_number() over (order by (select null)) as id from STRING_SPLIT(#SEQList,'|'))
SEQList on DESCLIST.id = SEQList.id
