Comma-Separated Value Insertion in SQL Server 2005

Comma-separated value insertion In SQL Server 2005

You need a way to split and process the string in TSQL, there are many ways to do this. This article covers the PROs and CONs of just about every method:

"Arrays and Lists in SQL Server 2005 and Beyond, When Table Value Parameters Do Not Cut it" by Erland Sommarskog

You need to create a split function. This is how a split function can be used:

SELECT
    *
    FROM YourTable                               y
    INNER JOIN dbo.yourSplitFunction(@Parameter) s ON y.ID=s.Value

I prefer the number table approach to split a string in TSQL but there are numerous ways to split strings in SQL Server, see the previous link, which explains the PROs and CONs of each.

For the Numbers Table method to work, you need to do this one time table setup, which will create a table Numbers that contains rows from 1 to 10,000:

SELECT TOP 10000 IDENTITY(int,1,1) AS Number
    INTO Numbers
    FROM sys.objects s1
    CROSS JOIN sys.objects s2
ALTER TABLE Numbers ADD CONSTRAINT PK_Numbers PRIMARY KEY CLUSTERED (Number)

Once the Numbers table is set up, create this split function:

CREATE FUNCTION [dbo].[FN_ListToTableRows]
(
     @SplitOn  char(1)      --REQUIRED, the character to split the @List string on
    ,@List     varchar(8000)--REQUIRED, the list to split apart
)
RETURNS TABLE
AS
RETURN 
(
    ----------------
    --SINGLE QUERY-- --this will return empty rows, and row numbers
    ----------------
    SELECT
        ROW_NUMBER() OVER(ORDER BY number) AS RowNumber
            ,LTRIM(RTRIM(SUBSTRING(ListValue, number+1, CHARINDEX(@SplitOn, ListValue, number+1)-number - 1))) AS ListValue
        FROM (
                 SELECT @SplitOn + @List + @SplitOn AS ListValue
             ) AS InnerQuery
            INNER JOIN Numbers n ON n.Number < LEN(InnerQuery.ListValue)
        WHERE SUBSTRING(ListValue, number, 1) = @SplitOn
);
GO 

You can now easily split a CSV string into a table and join on it. To accomplish your task, set up a test table to insert into:

create table YourTable (col1 int, col2 int)

then create your procedure:

CREATE PROCEDURE StoredProcedureName
(
     @Params1  int
    ,@Array1   varchar(8000)
    ,@Params2  int
    ,@Array2   varchar(8000)
)
AS 

INSERT INTO YourTable
        (col1, col2)
    SELECT
        a1.ListValue, a2.ListValue
        FROM dbo.FN_ListToTableRows(',',@Array1)            a1
            INNER JOIN dbo.FN_ListToTableRows(',',@Array2)  a2 ON a1.RowNumber=a2.RowNumber
GO

test it out:

exec StoredProcedureName 17,'127,204,110,198',7,'162,170,163,170'
select * from YourTable

OUTPUT:

(4 row(s) affected)
col1        col2
----------- -----------
127         162
204         170
110         163
198         170

(4 row(s) affected)

SQL return a comma separated value list

This is the solution to above question:

SELECT ta.IDA, ta.ValueA, stuff((
    SELECT ', ' + cast(ValueB as varchar(max))
    FROM @TableB tb INNER JOIN @TableC tc ON tc.fIDB = tb.IDB
    WHERE tc.fIDA = ta.IDA
    FOR XML PATH('')
    ), 1, 2, '') AS Options
FROM @TableA ta

SQL 2005 Split Comma Separated Column on Delimiter

Yes, it's possible with CROSS APPLY (SQL 2005+):

with testdata (CommaColumn, ValueColumn1, ValueColumn2) as (
  select 'ABC,123', 1, 2 union all
  select 'XYZ, 789', 2, 3
  ) 
select 
  b.items as SplitValue
, a.ValueColumn1
, a.ValueColumn2
from testdata a
cross apply dbo.Split(a.CommaColumn,',') b

Notes:

1. You should add an index to the result set of your split column, so that it returns two columns, IndexNumber and Value.

2. In-line implementations with a numbers table are generally faster than your procedural version here.

eg:

create function [dbo].[Split] (@list nvarchar(max), @delimiter nchar(1) = N',')
returns table
as
return (
  select 
    Number = row_number() over (order by Number)
  , [Value] = ltrim(rtrim(convert(nvarchar(4000),
        substring(@list, Number
        , charindex(@delimiter, @list+@delimiter, Number)-Number
        )
    )))
  from dbo.Numbers
  where Number <= convert(int, len(@list))
    and substring(@delimiter + @list, Number, 1) = @delimiter
  )

Erland Sommarskog has the definitive page on this, I think: http://www.sommarskog.se/arrays-in-sql-2005.html

How do I expand comma separated values into separate rows using SQL Server 2005?

I arrived this question 10 years after the post.
SQL server 2016 added STRING_SPLIT function.
By using that, this can be written as below.

declare @product table
(
    ProductId int,
    Color     varchar(max)
);
insert into @product values (1, 'red, blue, green');
insert into @product values (2, null);
insert into @product values (3, 'purple, green');

select
    p.ProductId as ProductId,
    ltrim(split_table.value) as Color
from @product p
outer apply string_split(p.Color, ',') as split_table;

separate comma separated values and store in table in sql server

You will need to create a split function similar to this:

create FUNCTION [dbo].[Split](@String varchar(MAX), @Delimiter char(1))       
returns @temptable TABLE (items varchar(MAX))       
as       
begin      
    declare @idx int       
    declare @slice varchar(8000)       

    select @idx = 1       
        if len(@String)<1 or @String is null  return       

    while @idx!= 0       
    begin       
        set @idx = charindex(@Delimiter,@String)       
        if @idx!=0       
            set @slice = left(@String,@idx - 1)       
        else       
            set @slice = @String       

        if(len(@slice)>0)  
            insert into @temptable(Items) values(@slice)       

        set @String = right(@String,len(@String) - @idx)       
        if len(@String) = 0 break       
    end   
return 
end;

Then in your stored procedure, you will call the function to split your string:

ALTER PROCEDURE [dbo].[spInsertDistributionRuleListType]
(
  @Rule_ID int,
  @ListType_ID int,
  @Values VARCHAR(MAX)=NULL
)
AS
BEGIN

    INSERT INTO DistributionRule_x_ListType (Rule_ID, ListType_ID, Value)
    SELECT @Rule_ID, @ListType_ID, items
    FROM [dbo].[Split] (@Values, ',')  -- call the split function 

END

When you execute the stored procedure, it will split the values and insert the multiple rows into your table:

exec spInsertDistributionRuleListType 1, 2, '319,400,521,8465,2013';

See SQL Fiddle with Demo. This will insert the following result:

| RULE_ID | LISTTYPE_ID | VALUE |
---------------------------------
|       1 |           1 |    10 |
|       1 |           2 |   319 |
|       1 |           2 |   400 |
|       1 |           2 |   521 |
|       1 |           2 |  8465 |
|       1 |           2 |  2013 |

             FROM  #table
         ) AS A CROSS APPLY Data.nodes ('/M') AS Split(a)
         )s  inner join

          (SELECT A.staffID,  
             Split.a.value('.', 'VARCHAR(100)') AS Data  ,
             row_number() over (order by (select 1) ) as rank

        FOR XML PATH('') 
        ), 2, 1000)  as NewColumn
        FROM  #table

OutPut :

If You dont have function Split() then first create it.

create FUNCTION [dbo].[Split]
(
  @delimited nvarchar(max),
  @delimiter nvarchar(100)
) RETURNS @t TABLE
(
-- Id column can be commented out, not required for sql splitting string
  id int identity(1,1), -- I use this column for numbering splitted parts
  val nvarchar(max)
)
AS
BEGIN
  declare @xml xml
  set @xml = N'<root><r>' + replace(@delimited,@delimiter,'</r><r>') + '</r></root>'

  insert into @t(val)
  select 
    r.value('.','varchar(max)') as item
  from @xml.nodes('//root/r') as records(r)

  RETURN
END

How to convert comma separated NVARCHAR to table records in SQL Server 2005?

Possible duplicate of separate comma separated values and store in table in sql server.

Please try a precise one from Comma-Delimited Value to Table:

CREATE FUNCTION [dbo].[ufn_CSVToTable] ( @StringInput VARCHAR(8000), @Delimiter nvarchar(1))
RETURNS @OutputTable TABLE ( [String] VARCHAR(10) )
AS
BEGIN

    DECLARE @String    VARCHAR(10)

    WHILE LEN(@StringInput) > 0
    BEGIN
        SET @String      = LEFT(@StringInput, 
                                ISNULL(NULLIF(CHARINDEX(@Delimiter, @StringInput) - 1, -1),
                                LEN(@StringInput)))
        SET @StringInput = SUBSTRING(@StringInput,
                                     ISNULL(NULLIF(CHARINDEX(@Delimiter, @StringInput), 0),
                                     LEN(@StringInput)) + 1, LEN(@StringInput))

        INSERT INTO @OutputTable ( [String] )
        VALUES ( @String )
    END

    RETURN
END
GO

Check the requirement in other way using XML:

DECLARE @param NVARCHAR(MAX)
SET @param = '1:0,2:1,3:1,4:0'

SELECT 
     Split.a.value('.', 'VARCHAR(100)') AS CVS  
FROM  
(
    SELECT CAST ('<M>' + REPLACE(@param, ',', '</M><M>') + '</M>' AS XML) AS CVS 
) AS A CROSS APPLY CVS.nodes ('/M') AS Split(a)

Stored Procedure to Insert comma seperated values as multiple records

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);

Comma Separated values in SQL Query

STUFF + XML PATH will do the job:

SELECT STUFF(
             (SELECT Distinct ',' + cast (name as varchar(20)) 
              FROM contacts       
              FOR XML PATH (''))
             , 1, 1, '')
