    <p>Your <code>SQLException</code> clearly states that:</p> <blockquote> <p>You need to specify <code>Statement.RETURN_GENERATED_KEYS</code> to the <code>Statement.executeUpdate()</code> or <code>Connection.prepareStatement()</code>.</p> </blockquote> <p>This can be achieved as follows (adding an additional value on <code>Connection.prepareStatement()</code> method):</p> <pre><code>String SQL = ""; //whatever my String is PreparedStatement ps = connection.prepareStatement(SQL, Statement.RETURN_GENERATED_KEYS); ps.setString(1, "value"); //Other necessary ps.setXXX() methods //now update ps.executeUpdate(); ResultSet rs = ps.getGeneratedKeys(); </code></pre> <p>The <code>Statement.RETURN_GENERATED_KEYS</code> is key here.</p> <p>Hope this helps!</p> <p>PS: <a href="https://stackoverflow.com/questions/4224228/preparedstatement-with-statement-return-generated-keys">Useful resource</a>.</p> <hr> <p>@Charlie berg, since you prefer being lazy, I changed line 13 of your code to include the <code>Statement.RETURN_GENERATED_KEYS</code>:</p> <pre><code>ps = con.prepareStatement("INSERT INTO characters (level, fame, str, dex, luk, `int`, exp, hp, mp, maxhp, maxmp, sp, ap, gm, skincolor, gender, job, hair, face, map, meso, hpMpUsed, spawnpoint, party, buddyCapacity, messengerid, messengerposition, mountlevel, mounttiredness, mountexp, equipslots, useslots, setupslots, etcslots, monsterbookcover, watchedcygnusintro, vanquisherStage, dojopoints, lastDojoStage, finishedDojoTutorial, vanquisherKills, matchcardwins, matchcardlosses, matchcardties, omokwins, omoklosses, omokties, givenRiceCakes, partyquestitems, jailtime, accountid, name, world) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)", Statement.RETURN_GENERATED_KEYS); </code></pre> <p>Also, <code>Statement</code> class is of package <code>java.sql</code> (make sure you import correctly). :-)</p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
