    <p>Thank you guys for helping me out so much on this particular issue. I have managed to do everything that is required in this program except I cant get the results that I need to output to the GUI. I have looked at other forums and some have said output to a textField instead of a textArea but either way I still end up getting an error. </p> <p>Here is my error when my outputArea is set to textField using .append:</p> <pre><code>The method append(int) is undefined for the type JTextField. </code></pre> <p>I am just curious as to what I should use for this problem.</p> <pre><code>import java.awt.EventQueue;

    1. COEverything that I have found about this is how to convert the int array to a string array which I believe I have but I just cant figure out how to output to a GUI. I can output to the console in Eclipse but I cant output to the GUI. All I need to know is how to get the output from the console to the GUI.

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).
