No, forget that.
Using (=: var <value>) circumvents the relation management mechanisms.
In general, 'put>' (or 'put!>') is used instead of '=:' on DB entities.
Thus,

or

will not only be shorter, but calls 'put>' internally, causing indexes
and other relations to be properly handled.
This explains why 'select' couldn't find anything.
To do it explicitly, the equivalent would be
(dbSync)
(with (new (db: +Cls) '(+Cls))
(put> This 'a A)
(put> This 'b B)
(put> This 'c C)
...
(commit 'upd)
This )
Sorry, didn't notice this while answering your first mail ;-)
Cheers,
