Stored Procedure to Insert comma seperated values as multiple records - sql

Question

Please help me in creating a stored procedure which accepts comma separated values and inserts as multiple rows.
So one parameter #Name will contain values A,B,C and the other parameter #Id will contain values as 1,2,3
The table values after insertion should be as below:
Name Id
------------
A 1
A 2
A 3
B 1
B 2
B 3
C 1
C 2
C 3
How can I write a stored procedure that can insert the comma-separated values as shown above. Also, If the table already consists of a Name,id pair for example, if A,2 is already there in the table, then it should not insert.
I am using SQL Server 2005. Thanks in advance.

Answer 1

Something like this?
DECLARE #var1 VARCHAR(100)='A,B,C';
DECLARE #var2 VARCHAR(100)='1,2,3';
WITH rep1(name, delim) AS
(
SELECT #var1 name, ',' delim
UNION ALL
SELECT LEFT(name, CHARINDEX(delim, name, 1) - 1) name, delim
FROM rep1
WHERE (CHARINDEX(delim, name, 1) > 0)
UNION ALL
SELECT RIGHT(name, LEN(name) - CHARINDEX(delim, name, 1)) name, delim
FROM rep1
WHERE (CHARINDEX(delim, name, 1) > 0)
)
,rep2(id, delim) AS
(
SELECT #var2 id, ',' delim
UNION ALL
SELECT LEFT(id, CHARINDEX(delim, id, 1) - 1) id, delim
FROM rep2
WHERE (CHARINDEX(delim, id, 1) > 0)
UNION ALL
SELECT RIGHT(id, LEN(id) - CHARINDEX(delim, id, 1)) id, delim
FROM rep2
WHERE (CHARINDEX(delim, id, 1) > 0)
)
INSERT #table
(Name
,ID)
SELECT
r1.name
,r2.id
FROM rep1 r1
CROSS JOIN rep2 r2
LEFT JOIN #table t
ON r2.id=t.id
AND t.name=r1.name
WHERE (CHARINDEX(r1.delim, r1.name, 1) = 0)
AND (CHARINDEX(r2.delim, r2.id, 1) = 0)
AND t.name IS NULL
ORDER BY r1.name
,r2.id
OPTION (MAXRECURSION 0);

Here we are sepearting Comma Seperated into rows
IF OBJECT_ID('tempdb..#Temp') IS NOT NULL
DROP TABLE #Temp
IF OBJECT_ID('tempdb..#NewTemp') IS NOT NULL
DROP TABLE #NewTemp
Declare #Testdata table ( name Varchar(max), Data varchar(max))
insert #Testdata select 'A', '1,2,3'
insert #Testdata select 'B', '1,2,3'
insert #Testdata select 'C', '1,2'
insert #Testdata select 'A', '1,2,3,4'
insert #Testdata select 'C', '1,2,3,4,5'
;with tmp(name, DataItem, Data) as (
select name, LEFT(Data, CHARINDEX(',',Data+',')-1),
STUFF(Data, 1, CHARINDEX(',',Data+','), '')
from #Testdata
union all
select name, LEFT(Data, CHARINDEX(',',Data+',')-1),
STUFF(Data, 1, CHARINDEX(',',Data+','), '')
from tmp
where Data > ''
)
Then Inserting into Temp Table
select DISTINCT name, DataItem INTO #Temp
from tmp WHERE EXISTS (Select DISTINCT name,DataItem from tmp)
order by name
Here we are controlling entry of Duplicates we can observe combination won't repeat like (A,1),(B,1)Even though they are multiple
CREATE TABLE #NewTemp(name Varchar(max), Data varchar(max))
INSERT INTO #NewTemp (name,Data)
Select name,DataItem from #Temp
Select * FROM #NewTemp

You can go and create one user defined functions for splitting the comma separated values into rows as below
How this function will work and more on it can be found here
CREATE FUNCTION dbo.Split
(
#RowData nvarchar(2000),
#SplitOn nvarchar(5)
)
RETURNS #RtnValue table
(
Id int identity(1,1),
Data nvarchar(100)
)
AS
BEGIN
Declare #Cnt int
Set #Cnt = 1
DECLARE #index INT
SET #index = Charindex(#SplitOn,#RowData)
While (#index>0)
Begin
Insert Into #RtnValue (data)
Select
Data = ltrim(rtrim(Substring(#RowData,1,#index-1)))
Set #RowData = Substring(#RowData,#index+1,len(#RowData))
Set #Cnt = #Cnt + 1
SET #index = Charindex(#SplitOn,#RowData)
End
Insert Into #RtnValue (data)
Select Data = ltrim(rtrim(#RowData))
Return
END
Once this function is created, you can use it for your requirement as below
declare #Name VARCHAR(30)
declare #Id VARCHAR(30)
SET #Name = 'A,B,C'
SET #Id = '1,2,3'
select A.Data,B.Data FROM dbo.Split(#name,',') A ,dbo.Split(#id,',') B
