c# - How to insert an ObservableCollection property to a local sqlite-net db? -


i have quick question sqlite-net library can found here : https://github.com/praeclarum/sqlite-net.

the thing have no idea how collections, , custom objects inserted database, , how convert them when querying, if needed.

take model example:

[primarykey, autoincrement] public int id { get; set; } private string _name; // name of subject. i.e "physics" private observablecollection<lesson> _lessons;

preface: i've not used sqlite-net; rather, spent time reviewing source code on github link posted in question.

from first page on sqlite-net github site, there 2 bullet points should in high level understanding:

  • very simple methods executing crud operations , queries safely (using parameters) , retrieving results of query in typed fashion

in other words, sqlite-net work non-complex models; work best flattened models.

  • works data model without forcing change classes. (contains small reflection-driven orm layer.)

in other words, sqlite-net transform/map result set of sql query model; again, work best flattened models.

looking @ primary source code of sqlite.cs, there insertall method , few overloads insert collection.

when querying data, should able use get<t> method , table<t> method , there query<t> method take @ well. each should map results type parameter.

finally, take @ examples , tests more in-depth @ using framework.
