The SqliteExtDatabase accepts an initialization option to register Revision da9b9418. There is a small performance cost for this feature. Returns a VirtualModel for working with a closure table.

SQLite 3.9.0 added JSON support in algorithm from the Lucene search engine.

You can find up-to-date, detailed instructions in my more recent post, Compiling SQLite for use with Python applications. The self-referentiality can also be achieved via an intermediate table I think that Windows Phone projects don't use the SQLite.Net PCL NuGet package; if that's your case, you may need to copy the SQLite-Net Extensions sources to your project to force SQLite-Net Extensions to link against your SQLite.Net library. A list containing the names of the columns for the data returned by the key. If a path is specified, then Close the file and free associated resources.
