Java 8 JDBC: Insert Timestamp Code Example

mysql> desc my_uat.students;
+-----------------+-------------+------+-----+---------+----------------+
| Field           | Type        | Null | Key | Default | Extra          |
+-----------------+-------------+------+-----+---------+----------------+
| student_id      | int         | NO   | PRI | NULL    | auto_increment |
| student_name    | varchar(45) | NO   |     | NULL    |                |
| student_dob     | datetime    | NO   | PRI | NULL    |                |
| student_address | varchar(45) | NO   |     | NULL    |                |
+-----------------+-------------+------+-----+---------+----------------+

As you can see in the above students table I have a filed student_dob declared as datetime, in this example, we will see how to insert a timestamp into this field using JDBC PreparedStatement,

String url ="jdbc:mysql://localhost:3306/my_db";
String userName="root";
String password ="root123";
String insertQuery ="insert into students values(?,?,?,?)";

Connection connection = DriverManager.getConnection(url,userName,password);
PreparedStatement preparedStatement = connection.prepareStatement(insertQuery);
preparedStatement.setString(1, null);
preparedStatement.setString(2, "Huge");

preparedStatement.setObject(3,Instant.now());

preparedStatement.setString(4, "Ohio");
int result = preparedStatement.executeUpdate();

As you can see we have made use of the Java 8 Instance (Date and Time API) class in order to insert a timestamp into the Database using PreparedStatement setObject method.
