    <p>If I understand the question correctly, it sounds like you're after <a href="http://search.cpan.org/perldoc?SQL::Abstract" rel="nofollow noreferrer">SQL::Abstract</a>. First, we create an <code>SQL::Abstract</code> object:</p> <pre><code>use SQL::Abstract; my $sql = SQL::Abstract-&gt;new; </code></pre> <p>Now, as an example, we'll use it to insert some data into a table:</p> <pre><code>my %record = ( FirstName =&gt; 'Buffy', LastName =&gt; 'Summers', Address =&gt; '1630 Revello Drive', City =&gt; 'Sunnydale', State =&gt; 'California', Occupation =&gt; 'Student', Health =&gt; 'Alive', ); my ($stmt, @bind) = $sql-&gt;insert(’staff’,\%record); </code></pre> <p>This results in:</p> <pre><code>$stmt = "INSERT INTO staff (FirstName, LastName, Address, City, State, Occupation, Health) VALUES (?, ?, ?, ?, ?, ?, ?)"; @bind = ('Buffy','Summers','1630 Revello Drive', 'Sunnydale',’California','Student','Alive'); </code></pre> <p>The nice thing about this is we can pass it directly to DBI:</p> <pre><code> $dbh-&gt;do($stmt, undef, @bind); </code></pre> <p>Of course, you want to be updating records, not just inserting them. Luckily, this is also quite easy:</p> <pre><code>my $table = 'People'; my %new_fields = ( Occupation =&gt; 'Slayer', Health =&gt; 'Dead', ); my %where = ( FirstName =&gt; 'Buffy', LastName =&gt; 'Summers', ); my ($stmt, @bind) = $sql-&gt;update($table, \%new_fields, \%where); $dbh-&gt;do($stmt, undef, @bind); </code></pre> <p>This produces:</p> <pre><code>$stmt = 'UPDATE People SET Health = ?, Occupation = ? WHERE ( FirstName = ? AND LastName = ? )'; @bind = ('Dead', 'Slayer', 'Buffy', 'Summers'); </code></pre> <p>If you're after more information about <code>SQL::Abstract</code>, I recommend you look at its <a href="http://search.cpan.org/perldoc?SQL::Abstract" rel="nofollow noreferrer">CPAN page</a>. There's also a chapter in <a href="http://perltraining.com.au/" rel="nofollow noreferrer">Perl Training Australia</a>'s <em>Database Programming with Perl</em> manual, which are freely available from our <a href="http://perltraining.com.au/notes.html" rel="nofollow noreferrer">course notes page</a>.</p> <p>All the best,</p> <p><em>Paul</em></p> <p>Disclaimer: I'm managing director of Perl Training Australia, and therefore think that our course notes are pretty good.</p>

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).
