Thank you!

ID NAME City
1 ABC MCLEAN
2 ABC RESTON
3 BCD ASHBURN
4 BCD HERNDON
5 DEF CHICAGO
——————————————

Declare @Name varchar(MAX)
Select @Name = COALESCE(@Name+’,',”)+ ”” + Name + ”” FROM (Select Distinct NAME from Testtable) as t
Select @Name

Declare @Front Varchar(5000)
Select @Front = ‘(‘ + @Name + ‘)’
Select @Front

Select * from Testtable
Where (NAME in (@Front))

I want to see above query works, I want the @Front to work, as I have to use Variable to pass.

Appreciate any reply back .

Thanks

Thank you ,this article helped me a lot.

DECLARE @listStr VARCHAR(MAX)
SELECT @listStr = COALESCE(@listStr+’,’ , ”) + NumberCols
FROM (SELECT DISTINCT NumberCols from NumberTable) as t
SELECT @listStr

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

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

please refer: http://www.sqlyoga.com/2009/02/sql-server-get-comma-separated-list.html

Let me know if you have any other situations.

Thanks,

I want the record to be display

ID Name

1 abc, cde, efg
2 111,222,333
3 56

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

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

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,

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

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!
