The iBatis DAO layer can use your existing domain classes as is. This will tell you how to modify the XML configuration files for iBatis to control such things as connection pooling and results caching. The most common thing to do in dynamic SQL is conditionally include a part of a where clause.

Resources Introduction to iBatis Source: Introduction To iBatis The iBatis framework is a lightweight data mapping framework and persistence API that can be used to quickly leverage a legacy database schema to generate a database persistence layer for your Java application.
However, if you load such cmplete list and then immediately iterate through it toaccess the nested data, you will invoke all of the lazy loads, and thus performance could be very bad. As the generate-ibatis Ant task indicates, an abatorConfig. Here are the steps to compile and run the above-mentioned software. Table of Contents takes you straight to the book detailed table of contents.
In Clinton developed an application called JPetStore  to demonstrate that Java could be more productive than. Start simple, and evolve it a step at a time.
The foreach element is very powerful, and allows you to specify a collection, declare item and index variables that can be used inside the body of the element.
An association mapping works mostly like any other result. You will find the script with dummy data inside the sql folder. What if only the second condition was met?

The bind element lets you create a variable out of an OGNL expression and bind it to the context. So, after Complet introspects the database and generates the SQL Map files, each of the generated insert blocks in those files will be modified to add this select block: NET, and Ruby on Rails.
Result Maps are the answer that MyBatis provides to this problem. As I already mentioned on previous posts, the resultMap element is the most important and referrnce element in MyBatis. XML file using some additional tags.
This introduction shows iBatis configured for a database running on localhost, so obviously a locally running MySQL server is needed. There is a similar solution for dynamic update statements called set.
The iBatis framework can even be used in conjunction with Hibernate. Then, the SQL Map layer needs the following file that describes how to connect ibatks the database, the type of transaction manager to use refer to the iBatis documentation for a full explanation of transaction manager choicesand where to find the SQL Map files generated by Abator.
This file describes the DAO components generated by Abator:.
