232 Getting Started with pureQuery To use the pureQuery tools to generate the XML file, a subset of the XML JPA specification, Open the pureQuery interface class, right-click on the interface and select pureQueryGenerate XML. 11.7.2 EMFT JET template customization for code generation To generate code, the tooling uses Eclipse Modeling Framework Technologies(EMFT ) Java Emitter Templates (JET) templates. In order to generate your own customized code, you must override the default JET transformation by creating an EMFT JET project, creating the templates, and telling ODS to use your own transformations. The many different JET templates used by the pureQuery tooling are located in the com.ibm.datatools.javatool.transform.codegen plugin within ODS. For detailed information on creating the project, templates and overriding the default transformation refer to the ODS documentation for Creating Eclipse Modeling Framework Technologies (EMFT) Java Emitter Templates (JET) to generate customized code. The supported databases for code generation from templates are DB2 LUW, DB2 for z/OS, IDS, DB2 iSeries and Oracle. The following table lists some of the templates for code generation that are in the plugin: Name of template Supported DBMS Description GenTableBean.jet GenTableInlineJUnit GenTableInlineSample.jet GenTableInterface.jet DB2 LUW, DB2 for z/OS, IDS, Oracle DB2 LUW, DB2 for z/OS, IDS, Oracle DB2 LUW, DB2 for z/OS, IDS, Oracle DB2 LUW, DB2 for z/OS, IDS, Oracle Generates a bean that contains properties of columns of a table or view. Generates a JUnit test case that contains inline methods for accessing the corresponding database object. Generates a Java test class that contains inline methods for accessing the corresponding database object. Generates a Java interface that contains annotates methods for accessing the corresponding database object. GenTableInterfaceJUnit.jet DB2 LUW, DB2 for Generates a JUnit test case for

Generates a test class for testing the implementation of the corresponding interface. Table 11.2 - JET templates used for code generation from a database Table or View Once you have created your EMFT JET Transformation project and created a template to override one of the default templates, go to the pureQuery Transforms preference page and specify which transformation the workbench should use. An example is illustrated in Figure 11.7: Figure 11.7 - Overriding the default JET templates to generate your own customized code 11.8 Using static SQL with annotated-method style applications One of the benefits of the annotated method style is that you can use it to execute SQL statements statically. Refer to Appendix C for a brief overview of static SQL.
