SQL Server: Split equivalent in T-SQL
A nice equivalent to the Split Function in T-SQL
CREATE FUNCTION [dbo].[fn_split]
(
@sString nvarchar(2048),
@cDelimiter nchar(1)
)
RETURNS @tParts TABLE ( part nvarchar(2048) )
AS
BEGIN
if @sString is null return
declare @iStart int,
@iPos int
if substring( @sString, 1, 1 ) = @cDelimiter
begin
set @iStart = 2
insert into @tParts
values( null )
end
else
set @iStart = 1
while 1=1
begin
set @iPos = charindex( @cDelimiter, @sString, @iStart )
if @iPos = 0
set @iPos = len( @sString )+1
if @iPos - @iStart > 0
insert into @tParts
values ( substring( @sString, @iStart, @iPos-@iStart ))
else
insert into @tParts
values( null )
set @iStart = @iPos+1
if @iStart > len( @sString )
break
end
RETURN
END
