Am I missing a function somewhere to change the resulting array of
module:find(..) from [value, ... ] to something like [{fielname,
value}, ... ] like is used to set a new entry?

regards, Ruud

No, there is no such function. You could do it as follows:

Values = [{Field, module:Field(Rec)} || Field <-
module:db_field_names(), Rec <- module:find()]

note: this would work when find() returns just one result.

This could be done with find_first/3.
Thanx for the quick reply.
