    <p>You can put this at the top of <code>Constants.pm</code>:</p> <pre><code>package main; </code></pre> <p>In this case all the variables you define will be in the <code>main</code> namespace:</p> <pre><code>$main::x </code></pre> <p>or if you're feeling brave:</p> <pre><code>package; </code></pre> <p>In this case all the variables you define will be in an empty namespace:</p> <pre><code>$::x </code></pre> <p>Note that using <code>package</code> with no namespace is discouraged, and will apparently be deprecated in some versions of Perl. See the quote below.</p> <hr> <p>Quoting from <code>man perlfunc</code>:</p> <pre> package NAMESPACE package Declares the compilation unit as being in the given namespace. The scope of the package declaration is from the declaration itself through the end of the enclosing block, file, or eval (the same as the "my" operator). All further unqualified dynamic identifiers will be in this namespace. A package statement affects only dynamic variables--including those you've used "local" on--but not lexical variables, which are cre? ated with "my". Typically it would be the first decla? ration in a file to be included by the "require" or "use" operator. You can switch into a package in more than one place; it merely influences which symbol table is used by the compiler for the rest of that block. You can refer to variables and filehandles in other packages by prefixing the identifier with the package name and a double colon: $Package::Variable. If the package name is null, the "main" package as assumed. That is, $::sail is equivalent to $main::sail (as well as to $main'sail, still seen in older code). If NAMESPACE is omitted, then there is no current pack? age, and all identifiers must be fully qualified or lexicals. However, you are strongly advised not to make use of this feature. Its use can cause unexpected behaviour, even crashing some versions of Perl. It is deprecated, and will be removed from a future release. </pre> <hr> <p><strong>Edit:</strong> This question might be helpful as well: <a href="https://stackoverflow.com/questions/193020/how-do-i-use-constants-from-a-perl-module" title="How do I use constants from a Perl module?">How do I use constants from a Perl module?</a></p>

    1. COThanks. What I really needed is the piece about omitting "main".

    2. COI'm curious if it actually works. If it does, I'll remove the disclaimer at the top of the answer.

    3. COThis puts the constants in main::, but now you have to prefix all the constants with main::

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).
