I have a database which already contains a table "LocalLogin" and is properly set and can be queried without a problem, being set up the same way as my new table "PersonList". However when I try to execute a query on PersonList to select some values, I get the error
android.database.sqlite.SQLiteException: no such table: PersonList: , while compiling: SELECT ...
It gives me the idea that the table was never created, although I execute a create query in the onCreate method of my SQLiteOpenHelper class. Is having the same Database Name as LocalLogin the possible problem?
Here's the relevant code:
The Database Adapter class
public class GoingOutPersonListDbAdapter {
private static final String DATABASE_NAME = "GoingOutData";
private static final String DATABASE_TABLE_PERSONLIST = "PersonList";
private static final int DATABASE_VERSION = 1;
public static final String PERSONLIST_ID = "PersonList_id";
public static final String PERSONLIST_LOGIN = "Login";
public static final String PERSONLIST_PASSWORD = "Password";
private static final String TAG = "Debugstring";
private PersonListDatabaseHelper mPersonListDbHelper;
private SQLiteDatabase mDb;
private static final String DATABASE_CREATE =
"CREATE Table " + DATABASE_TABLE_PERSONLIST+ " ( "
+ PERSONLIST_ID + " integer PRIMARY KEY Autoincrement, "
+ PERSONLIST_LOGIN + " text NOT NULL,"
+ PERSONLIST_PASSWORD + " text NOT NULL );";
private final Context mCtx;
private static class PersonListDatabaseHelper extends SQLiteOpenHelper {
PersonListDatabaseHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db) {
Log.d(TAG,DATABASE_CREATE);
db.execSQL(DATABASE_CREATE);
}
}
public GoingOutPersonListDbAdapter(Context ctx) {
this.mCtx = ctx;
}
public GoingOutPersonListDbAdapter open() throws SQLException {
mPersonListDbHelper = new PersonListDatabaseHelper(mCtx);
mDb = mPersonListDbHelper.getWritableDatabase();
return this;
}
public Cursor searchPerson(String searchString) {
return mDb.query(DATABASE_TABLE_PERSONLIST, new String[] {PERSONLIST_ID, PERSONLIST_LOGIN, PERSONLIST_PASSWORD}, searchString, null, null, null, null);
}
}
In my activity class:
private GoingOutPersonListDbAdapter mPersonListDbHelper;
...
mPersonListDbHelper = new GoingOutPersonListDbAdapter(this);
mPersonListDbHelper.open();
...
//loginEditText is properly set
Cursor personList = mPersonListDbHelper.searchPerson(GoingOutPersonListDbAdapter.PERSONLIST_LOGIN + " = '" + loginEditText + "'");
startManagingCursor(personList);
If you're adding a new table, you need to increment your database version so onUpdate will fire and your database will be recreated with the new table.
