I need to find indepth information about the isolations levels in the <cftransacion> tag. I need to make sure that a selection of selects,inserts and updates are grouped and no other client can process the same page until the transation is complete. I have found some documentation but need reassurance that the isolation level within the tag is fully supportedby sql server. I am using sql server 7 and cold fusion server 4.5 .
