Re: Update anomaly.

What a strange bug! :shock: I've managed to duplicate it with a simplified case. Given this: VAR TEST4 REAL RELATION {ID INTEGER, RVA RELATION {RID INTEGER, STR CHAR}} KEY {ID}; INSERT TEST4 RELATION { TUPLE {ID 1, RVA RELATION {TUPLE {RID 11, STR 'A'}, TUPLE {RID 22, STR 'E'}}}, TUPLE {ID 2, RVA RE...

Re: Key violation

Thanks, D_INSERT does work as an alternative workaround. I'm more interested in reporting the bug than in finding workarounds. I wonder what other operations might also be affected if constraints aren't being enforced correctly. I've added this to my to-do list. Note that KEY constraints are handle...

Re: Invoking by double-click on .rdb file

So I eventually managed to get double-click on .rdb to work in V3.2 on Windows 10. I ran into a couple of minor problems to begin with. Both have gone away now so I don't need any fixes for them, but I thought I should report them anyway. 1. The very first attempt to double-click on ClickToOpen.rdb...
