Question

How can I Convert Java Timestamp (Timestamp data type) to MySQL timestamp vice versa?

Answer 1

If you’re using the JDBC API to access the database, and you’re using a PreparedStatement to for example execute an SQL INSERT statement, then you just set the timestamp as a parameter to the PreparedStatement:

Timestamp ts = ...; // wherever you get this from

PreparedStatement ps = connection.prepareStatement("INSERT INTO MYTABLE (ts) VALUES (?)");
ps.setTimestamp(1, ts);
ps.executeUpdate();

Likewise, when you’re doing a query that returns a timestamp, get it from the ResultSet by calling getTimestamp on it. Example:

Timestamp result = null;

Statement st = connection.createStatement();
ResultSet rs = st.executeQuery("SELECT ts FROM MYTABLE WHERE ...");
if (rs.next()) {
    result = rs.getTimestamp(1);
}

See the JDBC Tutorial.
