>>Greetings again comrades -

>>Background: I have a private data session in my form, but shockingly enough <g> have bombed out a few times in the middle of something. I'd tried to cancel the debugger, cancel the form, and fix the problem. Sometimes I could and sometimes I couldn't (many attempts at clear all, close all). It seems I'd often end up with several data sessions and sometimes Unknown data session .
>>
>>Today after one such episode I found that I got a "Data mismatch error" when trying to do an append in a form which had previously worked. After attempting to look at the database I got a message to the effect that this wasn't permitted in the middle of a transaction. It finally dawned on me that some of those datasessions were in the middle of transactions, and I had to go to them and do a rollback to set things right.
>>
>>So here are my questions: 1) How do you close out a private data session when this happens (i.e. is there another way besides what I did)? 2) Since it was a private data session, I don't understand why I'd get that message about transactions unless I was in that data session when I tried that maneuver. 3) Is Transaction not scoped (if that's the correct phrase) to the private datasession?

>Sylvia,
>Transactions are not *scoped* to current data session. It's like a read...clear read. In other words, you could "begin transaction" from command line and "end transaction" or "rollback" after running a lot of code. Where stucked do a rollback. But for the moment I would suggest to keep the transaction in a method where much code is not called. Think this scenario :

Begin transaction
>* Some code here
>* Error occurs and you cancel to fix
>* In second pass again error is not fixed and you cancel again
>* Another level of transaction has begun
>* Now the error is fixed but "end transaction" only ends the last one (3rd).

Cetin -

Thanks once again. If I understand you correctly, I should just type rollback until I can't rollback no more, no more;) (this is bad grammar, but a pun on an American song whose name I can't remember) But how do I get rid of all these data session hanging around (or perhaps what you're saying is clean up after each session and I won't have this trouble?)

P.S. Unrelated side note - I've been watching a program about Alexander the Great and they showed Turkey (as one of the many countries he mowed through). You have some pretty scenery!
