| - | ===== Sample JDBC Program ===== | ||
| - | |||
| - | The following is a very simple Java program that shows a basic connection to an Omnidex Environment and simple query processing. | ||
| - | |||
| - | <code java> | ||
| - | /* Omnidex JDBC Example: Simple Select */ | ||
| - | |||
| - | import java.io.*; | ||
| - | import java.sql.*; | ||
| - | |||
| - | public class OdxJDBCSample | ||
| - | { | ||
| - | public OdxJDBCSample() | ||
| - | { | ||
| - | } | ||
| - | |||
| - | // Main | ||
| - | public static void main(String[] args) | ||
| - | { | ||
| - | // Declare JDBC objects | ||
| - | Connection conn = null; | ||
| - | Statement stmt = null; | ||
| - | ResultSet rs = null; | ||
| - | |||
| - | // The SQL statement to be executed | ||
| - | String sql = "select NAME, PHONE from INDIVIDUALS"; | ||
| - | |||
| - | try | ||
| - | { | ||
| - | // Load and initialize the Omnidex JDBC driver | ||
| - | Class.forName("omnidex.jdbc.OdxJDBCDriver"); | ||
| - | |||
| - | // Connect to the Omnidex Environment File | ||
| - | conn = DriverManager.getConnection("jdbc:omnidex:[server1:7555]c:\\class\\simple.xml"); | ||
| - | |||
| - | // create the Statement object | ||
| - | stmt = conn.createStatement(); | ||
| - | |||
| - | // execute the sql | ||
| - | rs = stmt.executeQuery(sql); | ||
| - | |||
| - | // Print the results from the Result Set returned after the Select | ||
| - | while(rs.next()) | ||
| - | { | ||
| - | System.out.print(rs.getString(1) + "\t"); | ||
| - | System.out.println(rs.getString(2)); | ||
| - | } | ||
| - | } | ||
| - | catch(ClassNotFoundException ce) | ||
| - | { | ||
| - | System.out.println("Driver error: " + ce); | ||
| - | } | ||
| - | catch(SQLException se) | ||
| - | { | ||
| - | System.out.println("SQL error: " + se); | ||
| - | } | ||
| - | finally | ||
| - | { | ||
| - | // Close the Result Set, Statement and Connection objects */ | ||
| - | try | ||
| - | { | ||
| - | if(rs != null) | ||
| - | rs.close(); | ||
| - | if(stmt != null) | ||
| - | stmt.close(); | ||
| - | if(conn != null) | ||
| - | conn.close(); | ||
| - | } | ||
| - | catch(SQLException se) | ||
| - | { | ||
| - | System.out.println("Close error: " + se); | ||
| - | } | ||
| - | } | ||
| - | |||
| - | System.out.println("End of program."); | ||
| - | |||
| - | } // End Main | ||
| - | } // End Class | ||
