Disclaimer: I'm giving this answer from the perspective of someone who works for the company behind jOOQ. For instance, you can extract a query string from a jOOQ query like this:. The main reasaon why they do this is because they have already widely used Spring JDBC, and they don't want to have two types of query execution on their stack. Every API that you add to your stack will also add complexity and a set of rules to the way your stack behaves.
On the other hand, you have a set of features that you want to have implemented from those APIs. Let's identify those features:. This is a no-brainer.
You probably don't want to use MyBatis for that. That implementation as you've discovered was more of a proof of concept. So you came to the choice of jOOQ. This is something that I personally think you jumped to conclusions for too quickly.
MyBatis has a lot of very simple implementations for things, but in the case of caching, I'm pretty sure you want to implement a much more general caching strategy, e.
The same that I've said for caching is true here. MyBatis has a simple default implementation for your mapping algorithms, which might quickly not be enough as you move on to more complex mapping scenarios.
But much like caching, mapping is not really something that should be solved on a SQL level. You will find much better tools out there for the mapping per se - e. Model Mapper which has built-in jOOQ supportbtw. Or if you're in a Java 8 environment, you could just use regular functional programming techniques to map stuffe. So, my advice to you is: Identify the best tool for each one of the features you want on your stack, and see if those tools are easy to combine. We've taken extreme care when implementing jOOQ to allow for any third party application to plug in very easily into jOOQ e.
From my benchmark MyBatis has some serious perfomance issue on the mapping, Jooq as a much nicer performance curve. That's with Jooq on mapper. Also SimpleFlatMapper as an integration point with querydsl and spring data.Ps3 han psp
Especially I want to learn which one is more suitable for huge databases I mean complex queries. QueryDSL is a level of abstraction above criteria; Also, it is more similar to SQL so it might be easier to learn for people who have not touched Criteria before.

Querydsl is more compact more typesafe at least compared to Hibernate Criteria closer to JPQL syntax also available for other backends This answer is biased since I am a Querydsl contributor.
Could you explain how is it more type safe? With TypedQuery docs.Uicc samsung
Hibernate provides default caching for a session. And I found, queries which needed pagination, performs better as it seems DSL making extra queries which I do not need in case of Hibernate criteria on same DB config. Am I doing something wrong?

It is a first class persistence framework with support for custom SQL, stored procedures and advanced mappings.
It eliminates almost all of the JDBC code and manual setting of parameters and retrieval of results. A key element of Spring is infrastructural support at the application level: Spring focuses on the "plumbing" of enterprise applications so that teams can focus on application-level business logic, without unnecessary ties to specific deployment environments.
Sequelize is a promise-based ORM for Node. Doctrine 2 sits on top of a powerful database abstraction layer DBAL.Java and SQL have come a long way. SQL is an "ancient", yet established and well-understood technology. Java is a legacy too, although its platform JVM allows for many new and contemporary languages built on top of it.
Yet, after all these years, libraries dealing with the interface between SQL and Java have come and gone, leaving JPA to be a standard that is accepted only with doubts, short of any surviving options. So far, there had been only few database abstraction frameworks or libraries, that truly respected SQL as a first class citizen among languages.
They vary from L1 to L5 with "L5" being the highest. Visit our partner's website for more details. Due to the relational nature of SQL, this is quite different from what object-oriented and partially functional languages such as CScala, or Java can offer. It is very hard to formally express and validate joins and the ad-hoc table expression types they create. It gets even harder when you want support for more advanced table expressions, such as pivot tables, unnested cursors, or just arbitrary projections from derived tables.
With a very strong object-oriented typing model, these features will probably stay out of scope.

All of the above is a big motivation to make jOOQ better. For more competitor comparisons, see also the following recent articles:. The below list of compared features and attributes is meant to be objective and unbiased, even if it was written by the developer of jOOQ.
Here goes. The above comparison was made at a high level. On a high level, one can draw a clear line between the three products:. History is repeating itself. This is nothing new, but it takes wisdom and Elephant memory to remember when and how things had already happened in a similar way. Think about it this way:. It threw away all the nice subtle intricacies of each specific CPU architecture and made them all equal by using only the common denominator of functionality that each CPU had.
It took a while, but eventually C compilers got better at optimizing than humans and could actually take advantage of advanced instructions in a CPU. Starting out from a rather emotional and maybe not really objective comparison between jOOQ and Hibernate, this turned out to be quite an interesting discussion.
This blog is picking up momentum and thus, relevance. I have solved many problems that are worth discussion, and I know quite a few things about various RDBMS, and how they compare with each other.

Strictly speaking, that is not a domain-specific language, though : SQL dialects vary greatly in subtle ways. Any SQL building tool should be able to distinguish dialects. This blog contains many examples, such as RDBMS bind variable casting madness : Many syntax elements and more specifically functions can be simulated in dialects that do not natively support them.

Join us, your partner for…. Manuel Bernhardt has summarised a nice collection in his a post. See the full documentation here:. For instance, it is not immediately obvious how to connect several complex predicates in that WHERE clause, or if complex predicates are available at all.
From how we understand things, the map method that is invoked in the middle of the SQL statement between innerJoin and where can transform the intermediate DSL state using a lambda expression that allows for appending a leftJoin if needed. Obviously, this can be done in a more procedural fashion as well, by assigning that intermediate DSL state to a local variable. The fact that they constantly pop up in various APIs is no coincidence. Having a typesafe internal domain-specific language model SQL in a host language like Java or Scala brings great advantages.
But the disadvantages may shine through quickly, when the DSL is not carefully crafted in a completely foreseeable way. Read more about that here. I first discovered it during my regular jOOQ marketing work.
