    1. COIt's not relevant what language was used to create the page, read it using URL address e.g. when reading the contents of http://stackoverflow.com/questions/10857204 it does not matter a bit if it was written with ASP, PHP or any other language.

    2. COYou get a few things mixed up i'm afraid, eclipse is an IDE tool to help you develop a program, also apps for android. It also has an intern browser to view the result of your (web)app. It is however NOT a browser or a programming language itself and you need those to read the contents a any webpage. Show us the code you already have, then we can help.

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).
