Truncate table using Java JDBC Example

We can make use of Statement or PreparedStatement to truncate a database table using Java JDBC,

Table: student:

mysql> select * from student;
+------------+--------------+
| student_id | student_name |
+------------+--------------+
|          1 | Sam          |
|          2 | Andy         |
+------------+--------------+
2 rows in set (0.00 sec)

Java Code:

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

public class JdbcExampleTruncateTable {

    public static void main(String[] args) throws SQLException {

        String url = "jdbc:mysql://localhost:3306/my_uat";
        String userName = "root";
        String password = "root123";
        String truncateTableQuery = "truncate table student";
        Connection connection = null;
        try {

            connection = DriverManager.getConnection(url, userName, password);
            Statement statement = connection.createStatement();
            statement.executeUpdate(truncateTableQuery);
            System.out.println("Student table truncated!...");

        } catch (SQLException e) {
            System.out.println("Exception Occurred while truncating the table!");
            e.printStackTrace();
        } finally {
            connection.close();
        }
    }
}

Output:

Student table truncated!...

As you can see the table is now empty!
