Hi

I have a table with 2 columns UserID & BookingID.

I'll know the bookingID and a comma separated list of UserID's.

How would I insert the CSV list with a common BookingID, witout a cursor.

With BULK INSERT command. Here's an example:
BULK INSERT TableName
   FROM Filename -- Provide a string with full path to the filename
   WITH 
      (
         FIELDTERMINATOR =' |',
         ROWTERMINATOR =' |\n'
      );

Table
BookingID UserID
1                      ab
1                      cd
1                      ef
2                      ab
2                      xy

This is how the table looks the userID are in fact GUIDS

Passed into the proc for the first 3 in the table:

@BookingID as int = 1
@UserID as nvarchar(200) = 'ab,cd,ef'

Ok, I understood now.
You need to use Common Table Expression (CTE) for do the recursive split:
DECLARE @BookingID as int = 1
DECLARE @UserID as nvarchar(200) = 'ab,cd,ef'

;WITH SplitString(StartPos,EndPos)
    AS(
        SELECT 0, CHARINDEX(',',@UserID)
        UNION ALL
        SELECT EndPos+1, CHARINDEX(',',@UserID,EndPos+1)
        FROM SplitString
        WHERE EndPos > 0
    )
SELECT @BookingID Booking, SUBSTRING(@UserID,StartPos,COALESCE(NULLIF(EndPos,0),LEN(@UserID)+1)-StartPos) UserID
FROM SplitString

You can also use XML and Cross apply as follows:

DECLARE @BookingID int = 1
DECLARE @UserID nvarchar(200) = 'ab,cd,ef'


SELECT @BookingID As BookingID,  
     Split.a.value('.', 'VARCHAR(100)') AS UserID
 FROM  (SELECT
         CAST ('<U>' + REPLACE(@UserID, ',', '</U><U>') + '</U>' AS XML) AS String  
     ) AS A CROSS APPLY String.nodes ('/U') AS Split(a);
