Split a String value into rows

  • DO we have any function in SQL Server 2000 to split a string having multiple comma separated values into as many rows using SELECT statement??

    e.g. string like '2541,2542,5362,36585,36884'

  • Not that I know of. Possible the REPLACE function will work for you. Something like this:

    declare @STR varchar(50)

    set @STR = '2541,2542,5362,36585,36884'

    select replace(@str,',',char(13))

  • You can use replace and a little concatenation to convert to an XML document, then use OpenXML to treat it like a table.

  • This will do the work:

    DECLARE@delimited_stringVARCHAR( 100 )

    ,@start_positionSMALLINT

    ,@end_positionSMALLINT

    SELECT@delimited_string = '2541,2542,5362,36585,36884'

    ,@end_position = 1

    CREATE TABLE #list

    (start_positionSMALLINT NOT NULL

    ,end_positionSMALLINT NOT NULL

    )

    WHILE @end_position > 0

    BEGIN

    SELECT@start_position = @end_position

    ,@end_position = CHARINDEX( ',', @delimited_string, @end_position + 1 )

    INSERT#list( start_position, end_position )

    VALUES( CASE @start_position WHEN 1 THEN 1 ELSE @start_position + 1 END

    ,CASE @end_position WHEN 0 THEN LEN( @delimited_string ) + 1 ELSE @end_position END )

    END

    SELECTSUBSTRING( @delimited_string, start_position, end_position - start_position )

    FROM#list

    WHEREend_position > 0

    DROP TABLE #list

  • Mromm! Thanks it really works.. You guys are great.

  • You can also use ActiveX scripting within a DTS task and use the SPLIT command of VB, like so;

    split(YourString, ",")

    This will split a string(which in your case is one dimensional) at the character that is within the quotes. You can also use this to split a multi dimensional string if it has a column and a row delimeter like;

    1,2,3,4 | 1,2,3,4 | 1,2,3,4

    productarray=split(mystring,"|")

    creates a one dimensional array split at the | character then;

    for j=0 to ubound(productarray)

    MyArray=split(productarray(j),",")

    splits it into columns.

  • Here is the function I use. You can use it withing a join to filter other tables.

    Select * from fnSplit('2541,2542,5362,36585,36884', ',')

    Returns:

    ItemId Item

    ----------- ---------

    1 2541

    2 2542

    3 5362

    4 36585

    5 36884

    (5 row(s) affected)

    CREATE Function fnSplit

    (

    @List varchar(8000)

    , @Delimiter char(1) = ','

    )

    Returns @Temp1 Table

    (

    ItemId int Identity(1, 1) NOT NULL PRIMARY KEY

    , Item varchar(8000) NULL

    )

    As

    Begin

    Declare

    @item varchar(4000)

    , @iPos int

    Set @Delimiter = ISNULL( @Delimiter, ',' )

    Set @List = RTrim( LTrim( @List ) )

    -- check for final delimiter

    If Right( @List, 1 ) <> @Delimiter

    -- append final delimiter

    Select @List = @List + @Delimiter

    -- get position of first element

    Select @iPos = Charindex( @Delimiter, @List, 1 )

    While @iPos > 0

    Begin

    -- get item

    Select @item = LTrim( RTrim( Substring( @List, 1, @iPos -1 ) ) )

    If @@ERROR <> 0 Break

    -- remove item form list

    Select @List = Substring( @List, @iPos + 1, Len(@List) - @iPos + 1 )

    If @@ERROR <> 0 Break

    -- insert item

    Insert @Temp1 Values( @item )

    If @@ERROR <> 0 Break

    -- get position pf next item

    Select @iPos = Charindex( @Delimiter, @List, 1 )

    If @@ERROR <> 0 Break

    End

    Return

    End
