There is a better Option available for the same job.

select cast(NumberCols as varchar)+’,’ from NumberTable
for xml path (”)

it saves so many operations and rest all query it self speaks.

Better I make some example:
—————————————————————–
SELECT campaign_name
, ( SELECT member_email +’;’
FROM competition (NOLOCK)
WHERE campaign_key = C.c_key
FOR XML PATH(”)
) recipients
FROM campaigns (NOLOCK) AS C
WHERE DATE > GETDATE()

I prefer such:

Select name+’,’
from something
for xml path(”)

The POWER :-) of this solution that you can use this in subquerys also.

Hi Pinal,

In my company we need to do opposite of above and that is parsing the comma seperated values into rows of table.

I found following script which works very fast as I have parsed 20 million records in just under 5 mins.

Hope this will help others too.

–First Create a table with numeric values form 1 to 8000
CREATE TABLE Tally
(ID INT)

DECLARE @count INT

SELECT @count =1

WHILE @count < 8001
BEGIN
INSERT INTO Tally(ID)
SELECT @count

SELECT @count=@count+1
END

SELECT Comma_Seperated_List,
NULLIF(SubString(‘,’ + product_list + ‘,’ , ID , CharIndex(‘,’ , ‘,’ + product_list + ‘,’ , ID) – ID) , ”) AS ‘Value’
FROM Tally T,
My_table M
WHERE ID 0 –remove this line to keep NULL rows

Your comments are appriciated.

Thanks,
SK

Hi,

I used COALESCE in my project to reterive the comma separate values.

syntax :-

COALESCE (storage, separetor, startvalue)

storage :- variable which contain final output. In option 1 @listStr is storage.

separetor :- value which distigush between two item. for example here ‘,’ (comma) you can put any value like ‘/’,'A’.

startvalue :- list start with this value.

for example

I want Output : start , first,second,third,fourth,fifth

COALESCE(@listStr, ‘,’ , ’start,’).

thanks
Mahendra

Hi Pinal,

I have a column with dx codes separated by commas. I need to break these out into separate columns within the same table. How is this done or what is the best way to get this done?

Here is an example:
DX
————
V72.0, V32.0, 245.

OUTPUT NEEDED:

DX DX1 DX2 DX3
——– ——- —— ——-
V72.0, V32.0, 245. V72.0 V32.0 245

Thanks!
Mina
