INSERT INTO @DISTINCT_MSGLIST VALUES (CAST(@LIST1 AS VARCHAR(MAX)))
SET @LIST = SUBSTRING(@LIST, @POS+1, LEN(@LIST))
SET @POS = CHARINDEX(@DELIM, @LIST, 1)
WHILE @POS > 0
BEGIN
SET @LIST1 = LTRIM(RTRIM(LEFT(@LIST, @POS – 1)))
IF @LIST1 ”
SELECT @MAX = ITEM FROM @DISTINCT_MSGLIST WHERE S_NO = ISNULL((SELECT MAX(S_NO) FROM @DISTINCT_MSGLIST) ,0)
IF @MAX @LIST1
INSERT INTO @DISTINCT_MSGLIST VALUES (CAST(@LIST1 AS VARCHAR(MAX)))
SET @LIST = SUBSTRING(@LIST, @POS+1, LEN(@LIST))
SET @POS = CHARINDEX(@DELIM, @LIST, 1)
END
SELECT @RLIST = COALESCE(@RLIST+’,',”) + ITEM
FROM (SELECT ITEM FROM @DISTINCT_MSGLIST) T

RETURN @RLIST

END

The above function will display the unique msg sequence from the list

eg : – If you pass the string ‘A,A,B,B,A,B’ , this function gives the output as ‘A,B,A,B’

DECLARE @str varchar(100),@sep VARCHAR(10)
select @str = ’1,2,3,4′ ,@sep = ‘,’
;
WITH Split(stpos,Endpos)
AS( SELECT 0 stpos
,CHARINDEX(@sep,@str) Endpos
UNION ALL
SELECT Endpos+1
,CHARINDEX(@sep,@str,Endpos+1)
FROM split
WHERE Endpos > 0
)
SELECT SUBSTRING(@str,stpos,COALESCE(NULLIF(Endpos,0),LEN(@str)+1)-stpos)
FROM split

XS,S,M,L,XL,2XL,3XL turns into an output of 2XL,3XL,L,M,S,XS.

I need these to be in size order (S to 3XL). I have another column for SortPriority but this is not obeyed after running the function.

While I was searching for how to do something totally different, however, I actually revisited the dedupe problem and came up with the following:

declare @list nvarchar(max)
set @list = ’342,34,456,34,3454,456,aa,bb,cc,aa’
declare @x xml
declare @delim nvarchar(1)
set @delim = ‘,’

set @x = ”+replace(lower(@list),@delim,”)+”
select replace(cast(@x.query(‘distinct-values(data(/list/delim))’) as varchar(max)),’ ‘,@delim) as result

Basically I turn the delimited list in to XML and use ‘distinct-values’ to get rid of dupes.

One gotcha to keep in mind is ‘distinct-values’ appears to be an exact match comparison and is why I included the ‘lower()’ command. So if @list = ”342,34,456,34,3454,456,aa,bb,cc,aa,AA’ AND you are not able to leave the ‘lower()’ command in there, you’d get both ‘aa’ and ‘AA’ in the result.

Enjoy!

How about using While loop or cursor, Because I dont know any other simple method to solve this.

1. Write a while loop,
2. Every time assign Column2 value to a variable.
3. use another while loop and Use substring function to reduce the size of variable and each time you reduce the size you put value into a temporary table.
4. At the end of while loop, do a select * from temp table.

I have a requirement and wanted to know if you or anyone can help…

Table1

ID (Pkey) Column2 (Account numbers)

1001 U987654321
1002 123213121,3434334,881216665
1003 A123456789,C123456789
1004 U1818012, U808561773……

Column 1 is a unique ID number which is the Pkey. Column2 holds (Accoount numbers) and can have upto 12 account numbers. My requirement is convert them in to table like ….

1001 U987654321
1002 123213121
1002 3434334
1002 881216665
1003 A123456789
1003 C123456789
1004 U808561773
1004 U808561773
……..

Pls let me know how to accomplish this using SQL 2008.

Thanks,
Hari

Try out this simple solution.

CREATE FUNCTION DBO.RECU (@DATA NVARCHAR(1000))
RETURNS @RETTABLE TABLE
( COL1 NVARCHAR(200))
AS
BEGIN
IF LEN(@DATA) > 0 AND CHARINDEX (‘,’,@DATA) > 0
BEGIN
INSERT INTO @RETTABLE
SELECT LEFT(@DATA,CHARINDEX (‘,’,@DATA)-1) AS COL1
UNION ALL
SELECT COL1 FROM DBO.RECU(RIGHT(@DATA,LEN(@DATA)-CHARINDEX (‘,’,@DATA)))
END
RETURN
END

SELECT DISTINCT COL1 FROM DBO.RECU(’342,34,456,34,3454,456,aa,bb,cc,aa,’)

Thanks and Regards

I m wroking in MNC as SQL developer i required dis function but i m not getting it so can u help me out to get dis UDF and also wat it actually does.

Dispite being the SQL guy I think that this really looks like one of those problems that are best cracked with CLR.

Have a look at my post http://blogs.msdn.com/garyhope/archive/2009/01/15/sql-remove-duplicates-function-t-sql-vs-clr.aspx
where I provide a demonstation of how the CLR code executes at leat 3 times faster.

This could have been done in a few lines of code, and performed much better as well.

is not

SELECT @rlist = COALESCE(@rlist+@Delim,”) + item
