comparing these two

WHERE ((ITEM_ID=? AND PLANT_ID=?) OR (ITEM_ID=? AND PLANT_ID=?) OR ... (ITEM_ID=? AND PLANT_ID=?))

and

SELECT *
   FROM EntityClass AS T
  WHERE EXISTS (
    SELECT *
       FROM (VALUES (?,?), (?,?), (?,?), (?,?)) AS V(ITEM_ID,PLANT_ID)
     WHERE T.ITEM_ID = V.ITEM_ID
           AND T.PLANT_ID = V.PLANT_ID
  )

I'm wondering what makes the second faster, is the sql is more efficiency in DB or the parameter binding part in hibernate is faster .

could you try to run these two in sql server directly w/ values binded and see if there is any difference?

P.S. I have no idea if Sql Server supports that tuple syntax or not, if someone could verify it would be great.
