nice :-)

(..actually came to know these levels 6 years ago, I used (NOLOCK) in the select statements on DWH queries and was wondering rather than typing nolock for each table join.. is there any simple open/close of nolock for all the tables in that query? and thats where I came to know the isolation levels and started to use the read uncommited and read committed when needed, apart from these two I have not used any other level.)

Thanks for the question
