ormlite

I am using Android with ORMLite in a small app I am currently writing. The app aims to have a working Import/Export function, for which I use Simple XML framework. And everything works great, up to a point. The situation is as follows: Object A contains a foreign key referencing Object B, which references Object C through a foreign key itself. Exporting a database is great. Importing works to, with a small caveat, namely that it works as long as the IDs of all object are sequential and start from 1. But if the database is fragmented, i.e. I deleted a record here and there, after I export the

Dearest Stackoverflowers, I was wondering if anyone knows how to solve this the best way; I'm talking to an api which returns a json object like this: { "field1": "value1", "field2": "value2", "details": { "nested1": 1, "nested2": 1 } In java I have an object (entity) which for example, would have all these fields, but with the details as loose fields, so: field1, field2, nested1, nested2. This because It's an android project and I can't just go saving a class with info into my entity since I'm bound to ormlite. Is there any way to convert the fields flat into my object using GSON? note that I

I have: @ForeignCollectionField(eager = false) private ForeignCollection<Field> fieldCollection; and I want to fill this collection from data coming from web service because I want to insert this data to my Sqlite database. I tried to use this: boolean accessOnPremiseDb = false; String description; @ForeignCollectionField(eager = false) private ForeignCollection<Entity> entitiyCollection = new LazyForeignCollection<Entity, Integer>(null, accessOnPremiseDb, accessOnPremiseDb, null, description, accessOnPremiseDb); but I got the error Caused by: java.lang.IllegalStateException: Internal DAO

I would like to store some field of type ParentClass as json string into my database. I don't want to use Serializable interface and DataType.SERIALIZABLE cause it ties with full class name of serialized class. So I'm using the following code: class ParentClass { @DatabaseField(persisterClass = MyFieldClassPersister.class) private MyFieldClass myField; } where persister class a kind of: public class MyFieldClassPersister extends StringType { private static final MyFieldClassPersister singleTon = new MyFieldClassPersister(); public static MyFieldClassPersister getSingleton() { return singleTon;

What is the best way for querying by using the value of foreign object's field? Suppose I have these three classes. UnitResult class which describes amount of Units: @DatabaseTable public class UnitResult { public static final String ID_FIELD_NAME = "id"; public static final String UNIT_COLUMN_NAME = "unit"; public static final String RESULT_COLUMN_NAME = "result"; @DatabaseField(generatedId = true, columnName = ID_FIELD_NAME) public Integer id; @DatabaseField(foreign = true, canBeNull = false, columnName = UNIT_COLUMN_NAME) public Unit unit; @DatabaseField(canBeNull = true, columnName =

I have to join two independent tables in sqlite . They don't have any foreign key relationship. Example: Table A has a field name Table B has a field primaryName I want to do something like select A.* from A inner join B on A.name = B.primaryName where A.id = 10 and B.address is null ORMLite enforces foreign key, is there a way to do this in ORMLite ? Unfortunately the short answer is "not at this time". You can certainly use the raw query functionality to support this: http://ormlite.com/docs/raw-queries Edit: This has [finally] been added ORMLite. It has been checked into trunk and will be
