OnUpgrade () method, which requires three parameters: A SQLiteDatabase object, an old version number and a new version number, in this way, you can understand how to transform a database from an old model to a new model.The following code inherits SQLiteOpenHelper to create a database: import android.content.Context;import android.database.sqlite.SQLiteDatabase;import android.database.sqlite.SQLiteOpenHelper;public class MyDB

called FID. A counter is used to make the value unique. (2) Each time a form is successfully submitted, its FID must be stored in a dictionary object. We use a dedicated process to initialize the above data. Although each subroutine will call it in the futureDuring this period, it only runs once: Copy code The Code is as follows: Sub initializefid () If not isobject (Session ("fidlist") then Set SESSI
