Question

I have the following code (I simplified it & removed unrelevant parts)

public class MyDatabaseManager extends SQLiteOpenHelper {

    private SQLiteDatabase myDatabase;

    public DatabaseManager() {
    super(MyApp.getAndroidContext(), DATABASE_NAME, null, DATABASE_VERSION);

    myDatabase = getWritableDatabase();
    }

    @Override
    public void onCreate(SQLiteDatabase database) {

    database.execSQL("create table t1 (t1key INTEGER PRIMARY KEY,data TEXT,num REAL,timeEnter NUMERIC);");

    }

    @Override
    public void onUpgrade(SQLiteDatabase database, int oldVersion, int newVersion) {
    }

}

Now when I run queries against this database I get sqlite - no such table exception.

My breakpoint at database.execSQL hits and it doesn’t raise any exception(for example if I change the code to database.execSQL("asda") I get syntax error exception) so I think my SQL code is correct. Yet the table is not created.
I copied the database file to my pc and I looked in it with Sqlite browser and indeed my tables don’t exist there. There is only one table and that is something called android_metadata. Any ideas?

Sqlite doesn’t have a datatype for DATE. I would suggest changing it to an INTEGER and storing date.getTime() in it.
