OJDBC10 framework common errors and solutions

The OJDBC10 framework is an extended library of the Java connecting Oracle database, which provides the function of accessing and operating Oracle databases.However, when using the OJDBC10 framework, sometimes some common errors are encountered.This article will introduce several common OJDBC10 framework errors and provide corresponding solutions and Java code examples. 1. ClassNotFoundException: oracle.jdbc.driver.OracleDriver This error is usually caused by the lack of Oracle driver.The solution is to ensure adding the Oracle Driver (OJDBC10.JAR) to the class path of the project.The following is a sample code for adding paths: // Add the Oracle Driver to the class path Class.forName("oracle.jdbc.driver.OracleDriver"); 2. Sqlexception: ORA-00942: Table or view does not exist This error indicates that the access or view of access does not exist in the Oracle database.The solution is to ensure that the table or view name is used is correct, and the corresponding table or view in the connected database.The following is a example of Java code fragment for performing a simple query: try { // Create a database connection Connection connection = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe", "username", "password"); // Create a statement object Statement statement = connection.createStatement(); // Execute the query ResultSet resultSet = statement.executeQuery("SELECT * FROM my_table"); // Treatment results set while (resultSet.next()) { // Process each line of data } // Turn off the connection connection.close(); } catch (SQLException e) { e.printStackTrace(); } 3. Sqlexception: ORA-01017: The invalid user name/password; log in to be rejected This error indicates that the username or password provided is incorrect, which makes it impossible to connect to the Oracle database.The solution is to ensure the correct user name and password, and check whether the user credentials in the database are correct.Here are a example of Java code fragment for connecting to the Oracle database: try { // Create a database connection Connection connection = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe", "username", "password"); // connection succeeded System.out.println ("Successfully connected to Oracle database!");); // Turn off the connection connection.close(); } catch (SQLException e) { e.printStackTrace(); } These are some common OJDBC10 framework errors and corresponding solutions and Java code examples.It is hoped that you will be helpful for your error debugging and solution when you use the OJDBC10 framework.
