There are many split-functions out there. This is very fast because there is only two string manipulation functions involved, and not per-part string manipulation.
CREATE FUNCTION dbo.fnParseList ( @Delimiter CHAR, @Text VARCHAR(8000) ) RETURNS @Result TABLE (RowID SMALLINT IDENTITY(1, 1) PRIMARY KEY, Data VARCHAR(8000)) AS BEGIN DECLARE@NextPos SMALLINT, @LastPos SMALLINT SELECT@NextPos = 0 WHILE @NextPos <= DATALENGTH(@Text) BEGIN SELECT@LastPos = @NextPos, @NextPos =CASE WHEN CHARINDEX(@Delimiter, @Text, @LastPos + 1) = 0 THEN DATALENGTH(@Text) + 1 ELSE CHARINDEX(@Delimiter, @Text, @LastPos + 1) END INSERT@Result ( Data ) SELECTSUBSTRING(@Text, @LastPos + 1, @NextPos - @LastPos - 1) END RETURN END
A short but interesting article, the author has figured out a way to create a PDF from a stored procedure without using a third party library.
