Getting Startedwith pureQuery

Appendix A – Solutions to the review questions 311
8. Each of the implementation classes implements com.ibm.pdq.runtime.Data,
in addition to the interface of annotated methods. This is helpful because you can
use the methods to manage the java.sql.Connection object that the instance
contains, and to perform transaction management for the SQL statements that the
annotated methods execute.
9. Cast the instance as a com.ibm.pdq.runtime.Data object and call the
close() method in the Data interface.
10. Some of the benefits of using the annotated-methods style are:
A. You can speed-up your application development. All you have to do is
declare methods that specify the SQL statement, the parameters, and the
return type, and the tools take care of the rest of the work.
B. You can use annotated-methods style code to execute SQL statements
statically.
C. The interfaces containing annotated methods help to isolate the SQL
statements from the application code.
11. The user must override the default JET transformation by creating an EMFT JET
project, creating the templates and telling ODS to user 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.
Once you have created your EMFT JET Transformation project and your template
to override one of the default templates provided, go to the pureQuery Transforms
preference page and specify which transformation the workbench must use.

1. You execute stored procedure calls with the call methods in the
com.ibm.pdq.runtime.Data interface.
2. You use the com.ibm.pdq.annotation.Call annotation to have an annotated
method execute a stored procedure call.
3. A and C
4. B and C
5. False
6. B
7. Assume that the name of the StoredProcedureResult object is spr. Use this
code: Integer parm4 = (Integer) spr.getOutputParms()[3]
8. You can call the close() method. Also, if you retrieve all of the query results,
pureQuery automatically frees the database resources.
