Write native SQL in Core Data

由 时光怂恿深爱的人放手 提交于 2019-12-20 03:11:14
问题 I need to write a native SQL Query while I'm using Core Data in my project. I really need to do that, since I'm using NSPredicate right now and it's not efficient enough (in just one single case). I just need to write a couple of subqueries and joins to fetch a big number of rows and sort them by a special field. In particular, I need to sort it by the sum of values of their child-entites. Right now I'm fetching everything using NSPredicate and then I'm sorting my result (array) manually, but

Hibernate: Can I return a non-mapped list of objects that contains a List?

由 牧云@^-^@ 提交于 2019-12-13 18:12:34
问题 I currently use .addScalar and ResultTransformer to return a non-mapped list of objects that do not have any List variables. I'd like to modify my object to contain a List. Following an initial example provide in Hibernate documentation, I successfully accomplished something similar to: sess.createSQLQuery("SELECT ID as id, NM_CDE as nameCode, NM_VALUE as nameValue FROM EMP") .addScalar("id", Hibernate.LONG) .addScalar("nameCode", Hibernate.STRING) .addScalar("nameValue", Hibernate.STRING)

How To Utilize Doctrine2 Type Conversion on Native Query COLUMNS

由 独自空忆成欢 提交于 2019-12-12 12:06:48
问题 Could not find anything on this-- seems like it should be straight forward though. So the example the Doctrine2 docs give for type conversion on bound parameters looks like this: $date = new \DateTime("2011-03-05 14:00:21"); $stmt = $conn->prepare("SELECT * FROM articles WHERE publish_date > ?"); $stmt->bindValue(1, $date, "datetime"); $stmt->execute(); What I want to do is specify the type conversion for one of the columns, but there is nothing in the documents or on StackOverflow that I

Spring data - insert data depending on previous insert

由 你。 提交于 2019-12-10 16:28:33
问题 I need to save data into 2 tables (an entity and an association table). I simply save my entity with the save() method from my entity repository. Then, for performances, I need to insert rows into an association table in native sql . The rows have a reference on the entity I saved before. The issue comes here : I get an integrity constraint exception concerning a Foreign Key. The entity saved first isn't known in this second query. Here is my code : The repo : public interface

Difference between query, native query, named query and typed query [closed]

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 4 years ago . What are the differences between a query, a native query, a named query and a typed query? Does the 'alone-standing' query even exist, or is it just an abbreviation?
