Insert statement whith unknown number of values extracted from a string - php

Question

I have a stored procedure in a sql server 2008 db.
This stored procedure takes a parameter that is a list of max 5 comma separated integer values. This string is passed through a php sript and formatted like this:
01,02,03,14,15
These values should go in this table:
Id | Type id
-------------
1 | 1
1 | 2
1 | 3
1 | 14
1 | 15
...where id is the same and type id is one of the comma separated values.
Obviously, I could have a string like "01,02,03" with only 3 values. So I need a way to insert only 3 rows in the above table resulting in:
Id | Type id
-------------
1 | 1
1 | 2
1 | 3
I could modify either the php script or the stored procedure, so I'm open to all kinds of suggestion.

Answer 1

You could create a function to help you do this.
CREATE FUNCTION dbo.Split(#origString varchar(max), #Delimiter char(1))
returns #temptable TABLE (items varchar(max))
as
begin
declare #idx int
declare #split varchar(max)
select #idx = 1
if len(#origString )<1 or #origString is null return
while #idx!= 0
begin
set #idx = charindex(#Delimiter,#origString)
if #idx!=0
set #split= left(#origString,#idx - 1)
else
set #split= #origString
if(len(#split)>0)
insert into #temptable(Items) values(#split)
set #origString= right(#origString,len(#origString) - #idx)
if len(#origString) = 0 break
end
return
end
Then you can call this function to split out the parameter values:
Not 100% sure where the ID value comes from so I have declared a variable.
Declare #newId int
Set #newId = 1
Insert Into dbo.MyTable (ID, TypeId)
Select #newId, *
From dbo.Split(#ParameterValues, ',')

Answer 2

I would pass XML into SQL server, which can then easily be processed as nodeset (like a table) using OPENXML or using the nodes() function on the xml datatype. It works very well and it's quite performant, almost always faster than any handmade string processing code.
DECLARE #x xml;
SET #x = '<id>01</id><id>02</id><id>03</id><id>14</id><id>15</id>';
SELECT x.id.value('.', 'int') FROM #x.nodes('id') AS x(id);

If you pass in 5 arguments, you could do something like this:
-- simulation of the arguments
DECLARE #p1 INT, #p2 INT, #p3 INT, #p4 INT, #p5 int;
SELECT #p1=1, #p2=2, #p4=14;
-- Select only parameters which aren't null
SELECT #p1 AS id WHERE #p1 IS NOT NULL
UNION ALL
SELECT #p2 WHERE #p2 IS NOT NULL
UNION ALL
SELECT #p3 WHERE #p3 IS NOT NULL
UNION ALL
SELECT #p4 WHERE #p4 IS NOT NULL
UNION ALL
SELECT #p5 WHERE #p5 IS NOT NULL;
