Upgrading the SQLite Database of a Production Android App, is this Correct?
When I need to update a database like this, I typically do it with a switch statement where cases fall through to one another, such as:
switch (oldVersion) { case 1: // update to version 2 // do _not_ break; -- fall through! case 2: // update to version 3 // again, do not break; case 3: // you're already up to dateThe benefits to this is you do not end up repeating your update statements in multiple if-statements as you continue to change the database, and adding a database update requires only adding a new case statement, not updating multiple blocks of code.
There are sometimes exceptions to this, such as a column added in one version but then deleted in a future one, so you need to pay attention as you go.
