ormlite

问题 I need to write following Query in ORMLite SELECT * FROM T1 t1, T2 t2 where t1.id = t2.id AND t1.type='abc' AND (t1.title = 'XYZ' OR t2.description = 'xyz'); However So Far I have been able to write following code: QueryBuilder<T1, Integer> t1QB = getT1Dao().queryBuilder(); QueryBuilder<T2, Integer> t2QB = getT2Dao().queryBuilder(); t1QB.join(t2QB); Where<T1, Integer> where = t1QB.where(); where.eq("Type", "abc"); where.and().or( where.ne("title", "XYZ"), where.ne("description", "xyz"), );

问题 For example : i need an Animals table which will contain animal_type as Object or T type as foreign relation field. then i will have 10 different tables like Dog/Cat/Horse etc. at the time of insertion based on type of animal i would set animal_type of Animal object. I don't want to take multiple databaseField for each type as a foreign relation, instead i need one generic field , Using ormlite version 5.0 . please refer this json: { "animal": { "type": 1, "content": { "items": [ { "title":

问题 I have this SQL. select sum(distance) AS distance FROM RoadTravelTableFile where checkBoxBusiness ='1' and plate_Number = 'AAA567'" I have seen this simple query for raw sql in the Ormlite document. long maxUnits = orderDao.queryRawValue("select max(units) from orders"); With that example, I coded my sql like this and it works. distance = (int) getHelper().getRoadTravelTableFileIntegerDao().queryRawValue("SELECT SUM(distance) FROM RoadTravelTableFile where checkBoxBusiness = '1' and plate

问题 The guide written here only says which files I need for installing ORMLite: http://ormlite.com/docs/getting-started But I don't see an explanation of how exactly I have to import these files into my project and where, and how to set the "classpath"? 回答1: Download the jars Put it in your libs folder in project add jar to class path. Right Click on your project -> Build path -> Confiugre build path Select libraries -> add Jar, then choose jar from your libs. 回答2: With the newest versions of ADT

问题 I have recently read inside documentation for Realm database that all of their queries are lazy and I am not sure, if I understand correctly the implications which this may cause. Let me explain how I understand it and please feel free to correct me if I'm wrong. The way I see it is that, whenever I am making such command mRealm.where(Customer.class).equalTo(Customer.ID, "someId").findFirst(); I do not get Java object with all filled data, that is contained in db for this customer. Instead

问题 I'm tring to make join in two tables and get all columns in both, I did this: QueryBuilder<A, Integer> aQb = aDao.queryBuilder(); QueryBuilder<B, Integer> bQb = bDao.queryBuilder(); aQb.join(bQb).prepare(); This equates to: SELECT 'A'.* FROM A INNER JOIN B WHERE A.id = B.id; But I want: SELECT * FROM A INNER JOIN B WHERE A.id = B.id; Other problem is when taking order by a field of B, like: aQb.orderBy(B.COLUMN, true); I get an error saying "no table column B". 回答1: When you are using the

问题 I would like to get information by a sql like this but in "ORMLITE" SELECT * FROM tableA a INNER JOIN tableB b on a.fieldA = b.fieldB ORDER BY a.fieldZ, b,fieldX; I try this in ORMLITE: QueryBuilder<B, Integer> bQuery = bDao.queryBuilder(); bQuery.orderby("fieldX", true); QueryBuilder<A, String> aQuery = aDao.queryBuilder(); aQuery.orderby("fieldZ", true); list = (List<T>) aQuery.join(bQuery).query(); But the result is not correct because it is not order by a.fieldZ . How can I do this? Thank

问题 I am trying to use ORMLite for database persistence in Android project. It looks all good from examples. Once I start to use it, I found I do not completely understand its requirement and behavior. Let's say I have a class called Bone which I would like to persist. @DatabaseTable(tableName = "bones") public class Bone{ // user defined @DatabaseField(dataType = DataType.STRING) private String color; @DatabaseField private double length; @DatabaseField private int quantity; // db assigned

问题 Right now I am trying to persist the Settings of an Application to my DB with the help of ORMLite . Well my settings consist of different String[] or ArrayList<String> or maybe a Map actually just a bunch of Strings . So my question is, what datatype should I use for such a scenario and optional maybe you could also provide me a small code example . Right now I tried different things, but I never was happy with the solution. I tried stuff like: private HashMap<String, ArrayList<String>>

问题 Background I have been trying to modify the Robospice Ormlite example code, which I have been successful to run. The only changes I have made is that I have a JSON response that contains an array of objects. I created 2 classes: public class Foos extends ArrayList<Foo> public class Foo I had initial problems, as my JSON response is a pure array with no outer container. I read via google groups that the way to solve this is to create a "fake" class (Foos) that extends an ArrayList. This
