Insert into Table Variable values from a comma separated list - sql

Question

declare #List varchar(25) = '2,3,4'
declare #Delinquencies table (id int);
insert into #Delinquencies(id) values('2'),('3'),('4'); --Line in question
#List is being populated with a string populated from an SSRS report for which choices they have picked. Now the way my stored procedure is running, I need to be able insert into my table variable based on what varchar list is coming through. How can I insert into a table variable with a dynamic varchar list? What is listed here is about as close to the testing format as I can come.
I am using SQL Server 2008.
Example
#List = '1'
insert into #Delinquencies(id) values('1')
And any combination up to
#List = '1,2,3,4'
insert into #Delinquencies(id) values('1'),('2'),('3'),('4')

Answer 1

Using one of the split string functions from here..
declare #List varchar(25) = '2,3,4';
declare #Delinquencies table (id int);
;with cte
as
(select * from
[dbo].[SplitStrings_Numbers](#list,',')
)
insert into #Delinquencies(id)
select * from cte

Answer 2

u need to create a dbo.StringSplit function
which takes two parameter (string, delimiter)
CREATE function [dbo].[StringSplit](
#String varchar (max),
#Delimiter nvarchar (10)
)
returns #ValueTable table ([Value] varchar(max))
begin
declare #NextString varchar(max)
declare #Pos int
declare #NextPos int
declare #CommaCheck nvarchar(1)
--Initialize
set #NextString = ''
set #CommaCheck = right(#String,1)
--Check for trailing Comma, if not exists, INSERT
--if (#CommaCheck <> #Delimiter )
set #String = #String + #Delimiter
--Get position of first Comma
set #Pos = charindex(#Delimiter,#String)
set #NextPos = 1
--Loop while there is still a comma in the String of levels
while (#pos <> 0)
begin
set #NextString = substring(#String,1,#Pos - 1)
insert into #ValueTable ( [Value]) Values (#NextString)
set #String = substring(#String,#pos +1,len(#String))
set #NextPos = #Pos
set #pos = charindex(#Delimiter,#String)
end
return
end
and then you can use it like below
declare #List varchar(25) = '2,3,4'
SELECT value from dbo.StringSplit(#List,',')

Here is a parser which returns the sequence as well.
For example:
Select * from [dbo].[udf-Str-Parse]('126,256,512',',')
Returns
Key_PS Key_Value
1 126
2 256
3 512
The UDF
CREATE FUNCTION [dbo].[udf-Str-Parse] (#String varchar(max),#Delimeter varchar(10))
--Usage: Select * from [dbo].[udf-Str-Parse]('Dog,Cat,House,Car',',')
-- Select * from [dbo].[udf-Str-Parse]('John Cappelletti was here',' ')
Returns #ReturnTable Table (Key_PS int IDENTITY(1,1), Key_Value varchar(max))
As
Begin
Declare #XML xml;Set #XML = Cast('<x>' + Replace(#String,#Delimeter,'</x><x>')+'</x>' as XML)
Insert Into #ReturnTable Select Key_Value = ltrim(rtrim(String.value('.', 'varchar(max)'))) FROM #XML.nodes('x') as T(String)
Return
End
