This tutorial will take you through the basic use of the c-treeACE SQL JDBC Interface.

Like all other examples in the c-tree tutorial series, this tutorial simplifies the creation and use of a database into four simple steps: Initialize(), Define(), Manage(), and You’re Done() !

Tutorial #1: Introductory - Simple Single Table

We wanted to keep this program as simple as possible. This program does the following:

• Initialize() - Connects to the c-treeACE Database Engine.
• Define() - Defines and creates a "customer master" (custmast) table/file.
• Manage() - Adds a few rows/records; Reads the rows/records back from the database; displays the column/field content; and then deletes the rows/records.
• Done() - Disconnects from c-treeACE Database Engine.

Note our simple mainline:

import java.sql.*;

import java.io.*;

public class JDBC_Tutorial1 {

   static Connection conn;

   static Statement stmt;

   //

   // main()

   //

   // The main() function implements the concept of "init, define, manage

   // and you're done..."

   //

   public static void main (String[] args)

      throws java.io.IOException

   {

      Initialize();

      Define();

      Manage();

      Done();

      System.out.print("\nPress <ENTER> key to exit . . .");

      System.in.read();

      System.exit(0);

   }

We suggest opening the source code with your own editor.
