ormlite

I'm trying to use inheritance with ORMLite and I can't work out if it is supported or not from looking at the documentation and googling. What I want to do is have public abstract class Person{ public int id; public String name; } public class Student extends Person{ public String school; public String year; // other student stuff } public class Teacher extends Person{ public String title; // other teacher stuff } What I can't work out (assuming it's supported) is how to annotate the 3 classes for ORMLite. Do I only need to annotate the concrete classes with @DatabaseTable(tableName = "Student

I'm using ORMLite in my Android project. I know that Sqlite takes care of the file level locking. Many threads can read, one can write. Locks prevent more than one writing. Could anybody please explain what will happen in case one thread is updating some record and another thread is trying to read this record? Will the thread (that is trying to read) get out-of-date data? Or will it be locked until the first thread completes its write-operation? As I know there are 4 transaction isolation levels: Serializable, Repeatable read, Read committed, Read uncommitted. And is there any way to change it

So here's the deal: I'm using ORMLite for Android, which uses annotations for it's mapping in Android. As you know, annotations are slow in Android, and the makers of ORMLite have realized this, so they added the ability to run a java executable to generate a resource file that bypasses the need to check annotations at runtime in the android app. It looks something like this: public class DatabaseConfigUtil extends OrmLiteConfigUtil { private static final Class<?>[] classes = new Class[] { SimpleData.class, }; public static void main(String[] args) throws Exception { writeConfigFile("ormlite

I am confused the which one good for android perspective either Ormlite or sqlite . please can you give me suggestion which one is better for use our android app. And makes easy to use and supported all android devices? I want to use the ormlite in our project but before i want to sure that it will be helfull for me and my app. So please guide me if any one used earlier this. I much appreciate your thought here.Thnaks Android Fanatic ORMLite is an open source software framework that provides lightweight object relational mapping (ORM) between Java classes and SQL databases. if you use this

I need to delete a record from ORMLite Database I can delete a record by id using as below @Override public void Delete(int id) throws SQLException { this.dao.deleteById(id); } but what if I have to delete a record from same table not by id but by name or any other field I want something like public void Deletefromcanteen(String name,MealType mealtype) { this.dao.deletebyName(name); } what query should i write using querybuilder to delete a record where name = name and mealtype = say (lunch) I tried something like this in my databasehelper class public void deletefromcanteen(int id, String

Question title just about says it all. I have a field declared like this: @DatabaseField(canBeNull=false,dataType=DataType.SERIALIZABLE) List<ScheduleTriggerPredicate> predicates = Collections.emptyList(); Depending on context, predicates can either contain the empty list or an immutable list returned by Collections.unmodifiableList(List) with an ArrayList as its parameter. I therefore know that the object in question is serializable, but there is no way I can tell the compiler (and therefore ORMLite) that it is. Therefore I get this exception: SEVERE: Servlet /ADHDWeb threw load() exception

I'm using Ormlite to persist some of the data from my Android app (running on a Motorola Xoom). By default, the sql database is saved to /data/data/[package name]/databases/[dbname].db. Trouble is, the Xoom is not rooted and therefore users do not have access to the directory where the db is saved (can't copy/backup/edit the content of the db). I have added some extra code into one of the classes to copy the db from /data to the sd card, which works fine, but realistically I think it should be possible to set the path for where the db is stored. Am I missing something, or is this not possible

As it is not possible to add foreign keys using an "ALTER TABLE" statement in SQLite, I am stuck on how to configure my database to enforce valid foreign keys, or perform cascaded deletes without explicit code overhead. Anybody got an idea how to accomplish this with ORMLite under SQLite? how to configure my database to enforce valid foreign keys, or perform cascaded deletes without explicit code overhead. ORMLite supports a columnDefinition="..." field in the @DatabaseFiled annotation @Timo. I'm not sure if it provides you the power you need but it does allow you to have custom column
