How to Use the Oracle Database Parser with JDBC in Java?

How can I use the Oracle Database parser from a Java application via JDBC?

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

Integrating the Oracle database parser into a Java application through JDBC (Java Database Connectivity) enables seamless execution of SQL queries and data manipulation. This guide outlines the necessary steps to establish a successful connection and perform database operations using JDBC.

String jdbcUrl = "jdbc:oracle:thin:@//hostname:port/service";
String username = "your_username";
String password = "your_password";

try (Connection connection = DriverManager.getConnection(jdbcUrl, username, password);
     Statement statement = connection.createStatement();
     ResultSet resultSet = statement.executeQuery("SELECT * FROM your_table")) {
    while (resultSet.next()) {
        System.out.println(resultSet.getString("column_name"));
    }
} catch (SQLException e) {
    e.printStackTrace();
}

Causes

• Incorrect JDBC URL format.
• Missing Oracle JDBC Driver in the classpath.
• Invalid database credentials.

Solutions

• Ensure that your JDBC URL is correctly formatted.
• Download and include the Oracle JDBC Driver (ojdbc8.jar) in your project.
• Verify that your database credentials (username and password) are correct.

Mistake: Forgetting to add the JDBC driver to the project.

Solution: Download the appropriate Oracle JDBC driver and add it to your project's build path.

Mistake: Using the wrong SQL syntax in queries.

Solution: Double-check SQL query syntax against Oracle's SQL documentation.
