    <p>First, thanks for the pointers! Partial answer follows ....</p> <p>What I've got so far ... first some scaffolding:</p> <pre><code># Connect to our db through DBIx::Class my $schema = My::Schema-&gt;connect('dbi:SQLite:/home/me/accounts.db'); # See also BEGIN { $ENV{DBIC_TRACE} = 1 } $schema-&gt;storage-&gt;debug(1); # Create an instance of our subclassed (see below) # DBIx::Class::Storage::Statistics class my $stats = My::DBIx::Class::Storage::Statistics-&gt;new(); # Set the debugobj object on our schema's storage $schema-&gt;storage-&gt;debugobj($stats); </code></pre> <p>And the definition of My::DBIx::Class::Storage::Statistics being:</p> <pre><code>package My::DBIx::Class::Storage::Statistics; use base qw&lt;DBIx::Class::Storage::Statistics&gt;; use Data::Dumper qw&lt;Dumper&gt;; use SQL::Statement; use SQL::Parser; sub query_start { my ($self, $sql_query, @params) = @_; print "The original sql query is\n$sql_query\n\n"; my $parser = SQL::Parser-&gt;new(); my $stmt = SQL::Statement-&gt;new($sql_query, $parser); #printf "%s\n", $stmt-&gt;command; print "The parameters for this query are:"; print Dumper \@params; } </code></pre> <p>Which solves the problem about how to hook in to get the SQL query for me to "pretty-ify".</p> <p>Then I run a query:</p> <pre><code>my $rs = $schema-&gt;resultset('SomeTable')-&gt;search( { 'email' =&gt; $email, 'others.some_col' =&gt; 1, }, { join =&gt; 'others' } ); $rs-&gt;count; </code></pre> <p>However SQL::Parser barfs on the SQL generated by DBIx::Class:</p> <pre><code>The original sql query is SELECT COUNT( * ) FROM some_table me LEFT JOIN others other_table ON ( others.some_col_id = me.id ) WHERE ( others.some_col_id = ? AND email = ? ) SQL ERROR: Bad table or column name '(others' has chars not alphanumeric or underscore! SQL ERROR: No equijoin condition in WHERE or ON clause </code></pre> <p>So ... is there a better parser than SQL::Parser for the job?</p>

    1. COI don't think there is, but SQL::Parser seems to be in active development (last update was Feb 6 this year). You should make sure you've got the latest version, and if it still breaks, contact the module maintainer and report your bug: http://rt.cpan.org/Public/Dist/Display.html?Name=SQL-Statement

    2. COThere's a brand-new module on CPAN called SQL::Beautify: SQL::Beautify - Article: http://annocpan.org/dist/SQL-Beautify Maybe it does what you need.

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).
