I have a datatable.

I want to perform a Bulk update in such a way that if a record is present in a table then it should be updated, else a new row should be inserted.

Is there any best way to do this in one shot?

I think you should bulk insert data in the staging or temp table and then write SQL statements to check for existing records before inserting in the main table.

If you are using SQL 2008, then you can use the new MERGE statement as well.

Try like that

CREATE PROC AlterSomeObj
 @act VARCHAR(10) = 'C',    
 @objXML xml     
AS    
    
IF (@act = 'C')    -- for creating
BEGIN    
    
 INSERT Table1(val1, val2)    
 SELECT     
    
  ITEM.TAB.value('val1[1]','VARCHAR(1000)') AS val1 ,    
  ITEM.TAB.value('val2[1]','VARCHAR(MAX)') AS val2 ,    
  FROM @objXML.nodes('ParentNode/ChildNode') ITEM(TAB)    
    
END    
ELSE IF(@act = 'U')     -- for updating
BEGIN    
 U Table1    
 SET     
 val1 = TAB.val1 ,     
 val2 = TAB.val2,    
    
 FROM     
  Table1 ITEMITEMS    
  INNER JOIN    
  (    
   SELECT    
    ITEM.TAB.value('val1[1]','VARCHAR(1000)') AS val1 ,    
    ITEM.TAB.value('val2[1]','VARCHAR(MAX)') AS val2 
    
   FROM @objXML.nodes('ParentNode/ChildNode') ITEM(TAB)    
  )TAB    
    
 ON ITEMITEMS.ID = @urlID    
   
    
END    
ELSE IF(@act = 'D')    -- for deleting
BEGIN    
--delete logic
END

As I think it will solve your problem
