Re: [Gusdev-gusdev] deleting objects/rows

[Deborah F. P. <pi...@pc...>]

We only use deleteEntries.pl in selected cases where there are no 
children. DeleteEntries.pl would fail if there were children of a row 
being deleted because of foriegn key contraints. In most of the cases that 
we want to delete rows with children, we write a plugin using objects. 
In that case, unless specified otherwise, deleted rows are versioned. I 
don't think there are any examples in the GUS set of plugins but I can 
send you an attached text if you need it.
