Thank you so much, Grace!

Hi Micheal,

Do you know that ntext data type can’t do concatenation. To overcome this problem, we can use UPDATETEXT.
The following are the example of using UPDATETEXT.

DECLARE @ptrval binary(16)
Declare @strComments nvarchar(4000)

SET @strComments = 'comments'

SELECT @ptrval = TEXTPTR(rd.Comment)
FROM vyRequisitionDetails rd
WHERE rd.RequisitionID = 'REQPhyuHT02012005-Delhi'

UPDATETEXT vyRequisitionDetails.Comment @ptrval NULL 0 @strComments
