SELECT snv_id = 'Not updating your browser already resulted in the following records being submitted with missing info:' + char(10) + STUFF((
SELECT ', ' + snv_id + ' ' + CONVERT(VARCHAR(10), Visit_Date, 101) + ' ' + Client_Last_Name + ' ' + ' ' + Client_First_name + char(10)
where _v_v_VisitNotes_Browser.nurse_User_ID_num_SNV= '[@authfield:Nurse_UserName]'
FOR XML PATH('')
