Re: 6.x tools and 7.x engine upgrade questions
} Hi, } } I have been presented with a project to convert our software package from } the 4.1x tools and 5.x engines to the latest and greatest 6.x tools and } 7.x engines. } } I was wondering if anyone had any horror stories about code that worked } fine using the 4.1x tools but broke horribly when you recompiled using the } 6.x tools and 7.x engine. } } I know I will either have to modify the programs or the tables because we } use rowids in some bits of the code, but wanted to know if there are any } other traps I should be watching for. } } Thanks, } } Alan } } ------------------------------------------------------------------------------ } Alan Goodman | Data Systems Support } Senior Systems Analyst | A Client Technologies Company } internet : alan@dssmktg.com | 1228 Shelly Ct. } Voice 714-771-0454 Fax 714-771-3028 | Orange, CA 92668 USA } ------------------------------------------------------------------------------ One of the differences between 4.x and >4.x is the argument count checking in functions. There is very strict checking in the newer versions, and nearly none in the older. If you just compile the old stuff and run it you could have *run-time* errors whenever you encounter a function with the wrong number of arguments. In the release notes there was an environment variable you could set which would disable the strict arg count checking, (I can't remember what the name of it is) but that's just buying some time. Also, there are data types in the newer versions which did not exist before. After the conversion you may find lots of unnecessary old code which jumps thru hoops to accomplish things that are very easy under the new version. (Things like datetime, interval, etc.) Good luck, __________________________________________________________________ | Clem Akins Standard Disclaimers Apply | |Reynolds Metals Co, Alloys Plant "Climb High, Cave Deep!" | | Muscle Shoals, Alabama USA cwakins@leia.alloys.rmc.com | |________________________________________________________________|
