I used to work for a company in Orlando where this was the case several years ago (just before the dot-com collapse), although unfortunately most of the companies I've worked for have taken an alternate route and simply decided that foreign-key constraints are not to be used (BLECH!). I use foreign-key constraints consistently in my own work but always handle them in an automated fashion, so I never have any real need for a naming convention, since I'm not hand-coding the create or drop statements generally speaking. I am of course, assuming that you know the difference between a foreign-key constraint (which ensures data integrity by producing an error if an insert/update/delete statement would create a conflicting state in the data - in other words it doesn't allow the database to ignore errors in your code), and simply having two tables which are joined in your ad-hoc queries. The former is what I use - the latter is what I'm forced to work with at my day-job. s. isaac dealey 954.522.6080 new epoch : isn't it time for a change? add features without fixtures with the onTap open source framework http://macromedia.breezecentral.com/p49777853/ http://www.sys-con.com/author/?id=4806 http://www.fusiontap.com ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Find out how CFTicket can increase your company's customer support efficiency by 100% http://www.houseoffusion.com/banners/view.cfm?bannerid=49 Message: http://www.houseoffusion.com/lists.cfm/link=i:4:200625 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
