I think you are saying that by changing from Having to Where, the SQL Select will run faster, right? Why, then, the original programmer didn't use Where in the first place? That is, I am concerned that there might be another reason he had "Having" instead of Where and I don't want to break it. Unless you think he was just drinking tequila when writing this code <g>
