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!
