Nuggets: Querydsl vs JPA 2.0 Criteria API: First-round knockout

http://rjewalker.blogspot.com/2010/06/querydsl-vs-jpa-20-criteria-api-first.html

Tuesday, 15 June 2010. Querydsl vs JPA 2.0 Criteria API: First-round knockout. DISCLAIMER: I am not affiliated with the Querydsl team in any way, shape or form. I've been developing with JPA on and off for a while now, only on small projects, but enough to be comfortable with it. Like everyone else, I soon reached the point where I thought "ergh, I don't much like embedding strings in my code to query my objects". @NamedQueries. So I came to the Criteria API that comes with JPA 2.0. Hey! My first non-tri...

First Look at Querydsl with JPA 2. Today I integrated integrated Querydsl. Into a java webapp that I recently started coding. The project was already using JPA 2 (Hibernate). I used JPQL to implement an initial set of finder methods for some simple use-cases, but I decided to explore alternatives to JPQL when I reached a use-case that required me to build a query dynamically based on a search form that contains about half a dozen search fields. More conditional checks more restrictions. To create criteri...

Mysema Blog: Querydsl as an alternative to the JPA 2 Criteria API

http://blog.mysema.com/2010/04/querydsl-as-alternative-to-jpa-2.html

Querydsl as an alternative to the JPA 2 Criteria API. Is our flagship Open Source project for type-safe queries in JDO, JPA, SQL and other querying languages. Last weekend I posted a thread. In our Mysema Source Forum. Related to the verbosity of JPA 2 Criteria queries. The thread presents JPA 2 and Querydsl queries side by side. Just that, not more. Here is one query comparison example. And now via Querydsl. A root path for the Person type is constructed like this in JPA 2 :. In Querydsl you just create...

Form Data Extraction with Backbone.js, Underscore.js and jQuery. Our weapon of choice for building single-page web applications is Backbone.js. Unlike a few of its competitors, such as Ember.js. Backbone does not support model binding out of the box. There are a some libraries that add model binding support to Backbone, probably first on the block was Backbone.ModelBinding. Which has now been discontinued, Backbone.ModelBinder. Are enough to get the ball rolling, as demonstrated below. An array of maps i...

Querydsl user survey results. A few weeks ago we opened the Querydsl user survey. To gather some information on how Querydsl is used and what direction it would make sense to take it.

Here is a summary of the results, the amounts are in percentages:. How have you heard of Querydsl? Invest into Querydsl...
