    <p>Stringbased values needs to be quoted in SQL string. But, better is to use <a href="http://download.oracle.com/javase/tutorial/jdbc/basics/prepared.html" rel="nofollow"><code>PreparedStatement</code></a>. Then you don't worry about quoting the values nor about escaping from <a href="http://unixwiz.net/techtips/sql-injection.html" rel="nofollow">SQL injection attacks</a>.</p> <pre><code>String sql = "INSERT INTO logfile VALUES(?, ?, ?, ?, ?, ?, ?, ?, ?)"; preparedStatement = connection.prepareStatement(sql); preparedStatement.setInt(1, logMessage.getCreator()); preparedStatement.setInt(2, logMessage.getCreatorParent()); preparedStatement.setInt(3, logMessage.getSequenceNumber()); preparedStatement.setInt(4, logMessage.getCreatorCost()); preparedStatement.setInt(5, logMessage.getCreatorEnergy()); preparedStatement.setInt(6, interval); preparedStatement.setInt(7, lplinterval); preparedStatement.setInt(8, logMessage.getData()); preparedStatement.setTimestamp(9, new Timestamp(tmp2.getTime())); // Assuming tmp2 is java.util.Date. preparedStatement.executeQuery(); </code></pre> <p><em>(and work on your <a href="http://www.oracle.com/technetwork/java/codeconv-138413.html" rel="nofollow">coding conventions</a>, yours is pretty terrible, also don't forget to properly close JDBC resources, you don't seem to take this into account as well)</em></p> <hr> <p><strong>Update</strong>: as per the comments, <code>tmp2</code> is a <code>String</code>. Here's how you could convert it to <code>Date</code> so that you can use it in <code>setTimestamp()</code> so that the value will be properly saved in a <code>DATETIME</code> column type. Since you didn't mention what date format the <code>tmp2</code> is in, I'll just take <code>"yyyy-MM-dd HH:mm:ss"</code> as an example:</p> <pre><code>String datestring = "2011-05-19 12:34:56"; // Just an example. Date date = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").parse(datestring); Timestamp timestamp = new Timestamp(date.getTime()); // Store in SQL string by PreparedStatement#setTimestamp(). </code></pre>

    2. COJDBC `Timestamp` is the right type for MySQL `DATETIME` type. See also http://download.oracle.com/javase/1.3/docs/guide/jdbc/getstart/mapping.html. You just need to convert `String` to `Date` by `SimpleDateFormat` and then wrap it in `new Timestamp()`.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
