This might hep for n number of columns :

*********************************************************************************************

DECLARE @Q NVARCHAR(4000),

@CName VARCHAR(255)

DECLARE ColCur CURSOR

FOR

SELECT C.name as Column_name

FROMsys.columns C

LEFT JOIN sys.tables t

on C.object_id = t.object_id

WHEREt.name = 'Your_table'

OPEN ColCur

FETCH NEXT FROM ColCur INTO @CName

WHILE(@@FETCH_STATUS =0)

BEGIN

SET @Q = 'UPDATE Your_Table SET '+@CName+' = NULL WHERE '+@CName+' ISNULL '

PRINT @Q

FETCH NEXT FROM ColCur INTO @CName

END

CLOSE ColCur

DEALLOCATE ColCur

No need for a cursor for something this simple. You can easily use the code I posted. All you need to do is add 'Update MyTable set' + [query results]

You could use STUFF to build up the comma delimited list of values, the values in this case are the column update sql strings. Then execute the string.
