Hi, Technicaly there probably is an overhead compared to the case where both tables are uncompressed, but when you're talking about MVC compression then I doubt if you can measure it. De-compressing a column compressed with MVC is a lookup of an in-memory array of values, so is trivial. Cheers, Dave Ward Analytics Ltd - Information in motion (www.ward-analytics.com)
