Well, thanks... and do you please have any idea what might cause
"inserting data without using ... etc."?
I do not mess with the SQL generation at all*, so I can't forget using
"select unique..." myself; all I am doing is creating EO's and then
calling editingContext.saveChanges -- which reports the aforementioned
error. Thus, self-evidently it's the EOF stack (or FrontBase plugin or
whoever) forgetting the "select unique"; how could I (a) find who it
is, (b) fix it?
* actually, I am exploiting the trick Cail Borrell suggested, to make
a unique sequential column by replacing a number value by some
generated SQL of lines "select max(xxx) from..."; but it should be
completely irrelevant here, for (a) it does not do anything with PK's
at all, (b) it is used with a different table anyway.
Thanks,
