It seems a common thread or belief that SQL will "use up" "ALL" of the available RAM given to a server.
And hand back to the OS as required/requested.
My understanding is that SQL will place the entire DBase into RAM if it can - also as queries come in + caching concurring it will try to use RAM. So lets say your database/s are 2GB total. You then give server 64GB of RAM - and there are few queries. Would you say then that SQL 2012 would "eventually" consume "all" of the RAM - even though the server is massively over spec'd for RAM
My thought is that to have a blanket statement that SQL will simply use up ALL of the RAM provided is not correct. Can this be verified please
