Steps to Create Association Between Database and JDBC-ODBC Bridge

Steps to Create Association Between Database and JDBC-ODBC Bridge

---

Step-by-Step Process:

Step 1: Create ODBC Data Source (DSN)

1. Go to Control Panel > Administrative Tools > ODBC Data Sources (32-bit or 64-bit).
2. Open the “System DSN” or “User DSN” tab.
3. Click on “Add”.
4. Choose a driver (e.g., Microsoft Access Driver (*.mdb) or SQL Server).
5. Provide a name (e.g., StudentDSN) and link it to the database file or server.
6. Click OK to save the DSN.

---

Step 2: Load the JDBC-ODBC Bridge Driver

Use the following line to load the bridge driver:

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

---

Step 3: Establish Connection

Use the DriverManager to connect using the DSN:

Connection con = DriverManager.getConnection("jdbc:odbc:StudentDSN");

---

Step 4: Create Statement Object

To execute SQL queries:

Statement stmt = con.createStatement();

---

Step 5: Execute SQL Query

For example, to read data:

ResultSet rs = stmt.executeQuery("SELECT * FROM student");

---

Step 6: Process the Result

while (rs.next()) {
    System.out.println(rs.getInt("id") + " " + rs.getString("name"));
}

---

Step 7: Close Connection

rs.close();
stmt.close();
con.close();

Summary of JDBC-ODBC Connection Steps

Step	Description
1	Create ODBC DSN pointing to your database
2	Load JDBC-ODBC driver
3	Connect using DriverManager.getConnection()
4	Create a Statement object
5	Execute SQL queries
6	Process results from ResultSet
7	Close all resources

Note:

• The JDBC-ODBC Bridge is deprecated and removed in Java 8+.
• For modern applications, use JDBC drivers provided by the database vendor (e.g., MySQL Connector/J, Oracle JDBC Driver).
