I'm guessing my issue is because I'm using asynchronous mode and perhaps the first statement (write) does not complete before the second statement (read) is run. I'll try with refactoring the code so that I make sure to do the read operation only after the write has completed.</p> Thanks for the reply.

If your connection in asynchronous mode, you have to wait first statement complete, then execute next statement.

Be careful on locks.

Since you seem to know some about transactions in SQLite and AIR, I have the following question that I hope you can answer:

Is it possible to have a SELECT statement after a INSERT or UPDATE statement in a transaction?

Reason I’m asking is I have a application where I can edit and insert items to a datagrid. Inserting new items happens through copy-pasting from the system clipboard, after which I would like the datagrid to update to reflect the change. But if I put both the INSERT and SELECT statement in the same transaction, my application crashes. The insert get’s run though, because the item is in the list if I relaunch the application. If I remove the SELECT statement, the application works (i.e. doesn’t crash). Any thoughts?
