Update makefile with a valid (userid,) password and // an available port number. // 2. Compile the server source file UDFjsrv.java (this will also // compile the Utility file, Util.sqlj, erase the existing // library/class file and copy the newly compiled class file, // UDFjsrv.class from the current directory to the // $(DB2PATH)\function directory): // nmake/make UDFjsrv // 3. Compile the client source file UDFcli (this will also call // the script 'udfjcat' to create and catalog the UDFs): // nmake/make UDFjcli // 4. Run the client UDFjcli: // java UDFjcli // // II) If you don't have a compatible make/nmake program on your // system, do the following: // 1. Compile the server source file with the following command: // javac UDFjsrv.java // 2. Erase the existing library/class files (if exists), // UDFsrv.class from the $(DB2PATH)\function directory. // 3. copy the class files, UDFsrv.class from the current // directory to the $(DB2PATH)\function. // 4. Register/catalog the UDFs with: // udfjcat // 5. Compile the utility file with the following command: // sqlj Util.sqlj // 6. Update bldsqljs and bldsqlj build files with a valid userid // and password. // 7. Build the SQLj UDFs with with: // bldsqlj UDFjcli // 8. Run UDFcli with: // java UDFjcli // // //*************************************************************************** // // For more information on the sample programs, see the README file. // // For information on developing Java applications see the Developing Java Applications book. // // For information on using SQL statements, see the SQL Reference. // // For the latest information on programming, compiling, and running DB2 // applications, visit the DB2 Information Center at // http://publib.boulder.ibm.com/infocenter/db2luw/v9r7/index.jsp //**************************************************************************/ import java.lang.*; // for String class import java.io.*; // for ...Stream classes public class UDFjsrv { // scalar UDF public static double scalarUDF(String inJob, double inSalary) throws Exception { double outNewSalary = 0.00; if (inJob.equals("Mgr ")) { outNewSalary = inSalary * 1.20; } else if (inJob.equals("Sales")) { outNewSalary = inSalary * 1.10; } else { // Job is clerk outNewSalary = inSalary * 1.05; } // set the output value return outNewSalary; } }
