![]() Note that InsertAllAsync returns the number of rows added. Var rowsAdded = await conn.InsertAllAsync(_resultList) If the table is empty then we continue on as we have in the past, but once we have data we populate the table if (response.IsSuccessStatusCode) List resultsFromSQL = await conn.Table().ToListAsync() ![]() We want to make a connection to a table (we’ll call it Result) and if it is empty, we’ll go ahead as we have been doing, but this time once we have the results we’ll populate the table for next time we need the data.įirst, let’s connect to the table and see how many results we get back await conn.CreateTableAsync() You are now ready to talk to the database. We do that with a couple simple attributes, and while we’re at it, let’s add a unique id. Modify the constructor to initialize the SQLite connection public ZipCodeService(IConnectivity connectivity)Ĭonn = new SQLiteAsyncConnection(fileName) īefore we proceed we need to teach our Result and Root model classes to be database classes. Private string fileName = Environment.GetFolderPath()+ can of course name your db whatever you want, and put it in any sandbox location. The bulk of the changes happen in ZipCodeServiceĪdd these two lines to the top of your class SQLiteAsyncConnection conn ![]() Required NuGet packages – You only need the third if you are building an Android app. Picking up where we left off, the first thing you’ll need are a couple NuGet packages. If it is empty, we’ll go out to the service, get our data, and stash it in the table.įor the purposes of this demo, I’m only going to create one table, after that it is just SQL. In this post we’ll create a table in SQLite and if it has anything in it, we’ll display the contents of the table. As an experienced XF programmer, you know that there are times you need a relational database, and SQLite has been the mobile db of choice for a very long time.
