    <p>Well, in C++0x you can...</p> <p>In C++03, there is a paragraph 23.1[lib.containers.requirements]/3, which says</p> <blockquote> <p>The type of objects stored in these components must meet the requirements of <code>CopyConstructible</code> types (20.1.3), and the additional requirements of <code>Assignable</code> types.</p> </blockquote> <p>This is what's currently preventing you from using <code>const int</code> as a type argument to <code>std::vector</code>.</p> <p>However, in C++0x, this paragraph is missing, instead, <code>T</code> is required to be <a href="http://en.cppreference.com/w/cpp/concept/Destructible" rel="nofollow noreferrer"><code>Destructible</code></a> and additional requirements on <code>T</code> are specified per-expression, e.g. <code>v = u</code> on <code>std::vector</code> is only valid if <code>T</code> is <a href="http://en.cppreference.com/w/cpp/concept/MoveConstructible" rel="nofollow noreferrer"><code>MoveConstructible</code></a> and <a href="http://en.cppreference.com/w/cpp/concept/MoveAssignable" rel="nofollow noreferrer"><code>MoveAssignable</code></a>.</p> <p>If I interpret those requirements correctly, it should be possible to instantiate <code>std::vector&lt;const int&gt;</code>, you'll just be missing some of its functionality (which I guess is what you wanted). You can fill it by passing a pair of iterators to the constructor. I think <code>emplace_back()</code> should work as well, though I failed to find explicit requirements on <code>T</code> for it.</p> <p>You still won't be able to sort the vector in-place though.</p>

    1. CO+1 Sounds like it might work - doesn't though with g++ 4.4.1 (latest I have) with `-std=c++0x`

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).
