Given the attitude of most dba's that you should always use bind variables where possible I can't see how you'd cope with skewed data without them. Most developers should know a databases's data better than the optimiser and certainly when building queries it's always worthwhile seeing where data is being most effectively filtered.

There are lots of mature systems out there where the data characteristics are unlikely to change much and for most in-house developers you're never going to have to think about portability but always about performance.

Hi,

Does Oracle have an official position on hints ? Will they go away as the optimiser is becoming bettre or they are there to stay ?
