Is 2.4MB Too Big for a Database File?

I have an SQLite database that's 2.4MB. I suspect it's the cause of lots of crashes in my app.

Has anyone included a DB that was as big or bigger? Any issues?

    Your code includes row.close(); – that the close for the ResultSet. This is correct; it's important to close the ResultSet when you're finished with it.
    However, you should also close the database itself when you've completed all your database operations. In your code above, that would be db.close();
    Not sure though if this is related to your problem.

  • Nope, I don't think it is too big.

    Have you checked whether you have close your DB connections at a timely fashion after using?

    • I think I'm closing it at a good time. My code is below.

      The strange thing is, I don't always make it to my first query and my database opening before my app crashes. It seems like it might be happening on my database install.

      var rows = db.execute('query...');
          //Loop through each row
          while (rows.isValidRow()) {
              //Create row                
                 var row = Titanium.UI.createTableViewRow({
                            className: 'searchResultsRow'
                  var locationID =  Titanium.UI.createLabel({
                  var airportName = Titanium.UI.createLabel({
                  row.className = 'searchResultsRow';

  • I have had a very similar problem with a large database. In my specific case, I kept getting errors with rows.isValidRow() where it complained that rows was null. Were you ever able to find a solution for this?

    • As far as I can tell, the size of the database isn't a problem. I had other unrelated issues what I was able to fix.

  • I don't think it should be a problem per se. However I did see issues when testing on Android where some internal limit was being broken when it was trying to copy the db file to the simulator - I have to do it manually instead.
