    <p>Your code seems to be a bit confusing. You say that you want to do different things based on what the user selected in JComboBox, but all that you are adding is the names of only rows where etat_syn is 0.</p> <pre><code> if(Integer.parseInt(res.getString("etat_syn"))==0){ jComboBox3.addItem(res.getString("name")) ; } </code></pre> <p>So in your case, no matter which item you select, the etat_syn value for that item will always be zero.</p> <p>I think (though I am guessing, you need something like below:</p> <pre><code>while(res.next()){ jComboBox3.addItem(res.getString("name")) ; jComboBox3.setActionCommand(res.getString("etat_syn")); } </code></pre> <p>and then in the action listener of <code>jComboBox3</code>, you can do like this:</p> <pre><code> jComboBox3.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent actionEvent) { String actionCommand = actionEvent.getActionCommand(); if("0".equals(actionCommand)) { //Do this } else { //Do something else. } } }); </code></pre> <p>If you want the processing to be in a action listener of a Button, then you can use a <code>Map</code> to store the values, which can then be used for comparision. Your code will change as below:</p> <pre><code>Map&lt;String, Integer&gt; itemsMap = new HashMap&lt;String, Integer&gt;(); //Declare this as a member of the class. while(res.next()){ String name = res.getString("name"); jComboBox3.addItem() ; int value = Integer.parseInt(res.getString("etat_syn")); itemsMap.put(name, value); } </code></pre> <p>and the action listener of the button will be as below:</p> <pre><code> yourButton.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent actionEvent) { String selectedItem = (String)jComboBox3.getSelectedItem(); int value = itemsMap.get(selectedItem); if(value == 0) { //Do this } else { //Do something else. } } }); </code></pre>

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.
