Working with heterogeneous collectionsThe java.sql.Array interface assumes that all elements in the array have thesame domain. Since Cincom ORDB collections can be heterogeneous, theordbCollection class provides additional methods for dealing withheterogeneous collections. These methods are:♦♦♦isHomogeneous() - Returns true if the elements of the database collectionare of the same domain.getBaseType(int index) - Returns the JDBC type (from java.sql.Types) ofthe specified element. (The first collection element is at index 1.)getBaseTypeName(int index) - Returns the database domain string for thespecified element.The following example demonstrates these methods and can be found in the%ORDB%\demo\jdbc\samples\collectionSample2.java file://// This example demonstrates the use of ordbCollection methods to deal// with heterogeneous Cincom ORDB collections.//package demo.jdbc.samples;import java.sql.*;import java.math.*;import java.io.*;import ordbjava.jdbc.*;import java.util.HashMap;//import for custom mappingclass collectionSample2 {public static void main (String args []) throws SQLException{// Connect to the demodb database without autocommit enabled.Connection conn = demodbHelper.makeConnection (false);/* select a heterogeneous set */Statement stmt = conn.createStatement ();ResultSet rset = stmt.executeQuery ("SELECT name, rooms FROM resort");JDBC Developer's Guide, P25-9504-03 Page 65Chapter: 4.
