ormlite

问题 Does ormlite support this three inheritance-strategies? table per class hierarchy table per subclass table per concrete class I found this discussion on the ORMLite user group, but I'm not sure it answers my question. Specially i want use "table per class hierarchy". If their isn't support from the ormlite framework i will make one class and forget the inheritance, but i would prefer to use inheritance. 回答1: ORMLite does not support these automatically, no. I'm not sure you actually read the

问题 I am not clever from ORMlite documentation. Is is possible to declare in class, that this parameter is foreign key? e.g. I have table Customer: @DatabaseTable(tableName = "customer") public class Customer { @DatabaseField(id = true) private String customerName; @DatabaseField private String customerSurname; @DatabaseField(foreign = true) private String accountNameHolder; @DatabaseField private int age; public Customer() { } } AccountNameHolder should aim towards DatabaseField name from table

问题 I'm using ORMLite in an android project, and I'm not wanting to use the extended activities because I'm inserting values into the database on an AsyncTask. In the docs it says: "If you do not want to extend the OrmLiteBaseActivity and other base classes then you will need to duplicate their functionality. You will need to call OpenHelperManager.getHelper(Context context, Class openHelperClass) at the start of your code, save the helper and use it as much as you want, and then call

问题 I'm wondering whether there's a way to extend the BaseDaoImpl class of ORMLite on Android. In my Android project I'm using several different Dao objects to access the different business objects. My business objects are stored in different tables and are all inherited form an BusinessObject base class which has the two members Long id; and Long objectId; where id is the real unique id of the object within the database table. public abstract class BusinessObject{ public static final String ID

问题 I am using ormlite.android.4.31.jar I have typical DatabaseHelper public class DatabaseHelper extends OrmLiteSqliteOpenHelper { private static final String DATABASE_NAME = "realestate.db"; private static final int DATABASE_VERSION = 1; private Dao<TabKraj, Integer> krajDao; public DatabaseHelper(Context context) { super(context, DATABASE_NAME, null, DATABASE_VERSION); } @Override public void onCreate(SQLiteDatabase sqliteDatabase, ConnectionSource connectionSource) { try { TableUtils

问题 This is my database: CREATE TABLE other ( id integer primary key autoincrement not null, texto text ); CREATE TABLE tabela (campoid INTEGER primary key autoincrement not null, camponome text not null, chave int, foreign key (chave) references other(id)); and this is my classes: @DatabaseTable(tableName = "tabela") public class Bean { @DatabaseField(columnName = "campoid", generatedId = true) private int _id; @DatabaseField(columnName = "camponome") private String nome; @DatabaseField(foreign

问题 I use ORMLite and now have got a question that I can not answer. Look at my example : I have class implementes Serializable. class Time implements Serializable { private long time; ...blabla } and class Operation that includes Time class Operation implements Serializable { private Time time; ...blabla } Operation is a database table but Time not. As I think Time stored in database as byte array because it is Serializable Object. The question is it right to use ORMLite query like eq(), between

问题 Is it possible to get the corresponding Dao in OrmLite , without passing class name to createDao , without a static type-checking ? Dao<Account, String> accountDao = DaoManager.createDao(connectionSource, Account.class); But insert or update record by passing table / attribute name as string? Do you know any Orm available for Android, can do this? 来源： https://stackoverflow.com/questions/40890602/get-dao-with-weak-typing-in-ormlite

问题 I'm new to Ormlite integration but managed to make it work on a learning project (android app) The issue that I'm facing is a performance + conceptual one . I'm using Jackson to get a list of Center objects then use ORMLite to persist everything into DB . My Center object has two ForeignCollectionField , my annotations are correct and with the above code I can get a correct "join" of the wastes that this center can handle and the nature of the center it self . I can check my DB using an
