    <p>There are pieces to this answer that helped me get what I needed (easy multi-line concatenation WITHOUT extra whitespace), but since none of the actual answers had it, I'm compiling them here:</p> <pre><code>str = 'this is a multi-line string'\ ' using implicit concatenation'\ ' to prevent spare \n\'s' =&gt; "this is a multi-line string using implicit concatenation to eliminate spare \\n's" </code></pre> <p>As a bonus, here's a version using funny HEREDOC syntax (via <a href="http://graysoftinc.com/ruby-voodoo/working-with-multiline-strings" rel="noreferrer">this link</a>):</p> <pre><code>p &lt;&lt;END_SQL.gsub(/\s+/, " ").strip SELECT * FROM users ORDER BY users.id DESC END_SQL # &gt;&gt; "SELECT * FROM users ORDER BY users.id DESC" </code></pre> <p>The latter would mostly be for situations that required more flexibility in the processing. I personally don't like it, it puts the processing in a weird place w.r.t. the string (i.e., in front of it, but using instance methods that usually come afterward), but it's there. Note that if you are indenting the last <code>END_SQL</code> identifier (which is common, since this is probably inside a function or module), you will need to use the hyphenated syntax (that is, <code>p &lt;&lt;-END_SQL</code> instead of <code>p &lt;&lt;END_SQL</code>). Otherwise, the indenting whitespace causes the identifier to be interpreted as a continuation of the string.</p> <p>This doesn't save much typing, but it looks nicer than using + signs, to me.</p> <p>EDIT: Adding one more:</p> <pre><code>p %{ SELECT * FROM users ORDER BY users.id DESC }.gsub(/\s+/, " ").strip # &gt;&gt; "SELECT * FROM users ORDER BY users.id DESC" </code></pre>

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.
