Selective field results

[mingard]

To retrieve only the fields you need, it could be useful to extend the .select() method to limit the returned fields. Something like:

.select({'name': 1, 'age': 1}).from({$p: Person})

also accepting arrays:

.select(['name', 'age']).from({$p: Person})

@mingard projections are already supported, e.g. db.select({name: {$e1: "name"}}).from({$e1: Object})

Granted the documentation in README.md only provides the signature and not an example, i.e. A <projection> takes the form {<propertyName: {<classVariable: "<objectProperty>"}[, ...]}.

Close this issue if it addresses your needs.

@anywhichway I suppose I was looking for some syntactic sugar, so rather than:

db.select({name: {$e1: "name"}, age: {$e1: "age"}}).from({$e1: Object})

something like:

db.select({$e1: ["name", "age"]}).from({$e1: Object})

perhaps even the ability to recognise that the request targets a single Object so:

// Multiple 
db.select({$e1: ["name", "age"], $e2: ["name":]}).from({$e1: Object, $e2: Object})
// Single
db.select(["name", "age"]).from({$e1: Object})

Perhaps there's room here for a reasondb-wrapper that takes care of query building?
