Body
You can use concept from relational algebra. <code>limit 1</code> does not give good result when more than one user have the same number of votes. On PostgreSQL: <pre><code>with t as (select name, count(*) c from voters group by name) SELECT t.* from t except SELECT t.* from t JOIN t t2 ON t2.c > t.c </code></pre> <a href="http://sqlfiddle.com/#!1/bc113/6" rel="nofollow noreferrer">Example on SQL Fiddle</a> And sample data to prove this works: <pre><code>create table voters (name int,vote int); insert into voters values (1,1); insert into voters values (1,1); insert into voters values (1,1); insert into voters values (1,1); insert into voters values (1,1); insert into voters values (1,1); insert into voters values (1,1); insert into voters values (1,1); insert into voters values (2,1); insert into voters values (2,1); insert into voters values (2,1); insert into voters values (2,1); insert into voters values (2,1); insert into voters values (2,1); insert into voters values (2,1); insert into voters values (2,1); insert into voters values (2,1); insert into voters values (3,1); insert into voters values (3,1); insert into voters values (3,1); insert into voters values (3,1); insert into voters values (3,1); insert into voters values (3,1); insert into voters values (3,1); insert into voters values (3,1); insert into voters values (3,1); insert into voters values (4,1); insert into voters values (4,1); insert into voters values (4,1); insert into voters values (4,1); insert into voters values (4,1); insert into voters values (5,1); insert into voters values (5,1); insert into voters values (5,1); insert into voters values (5,1); </code></pre> My solution is based on answer to this question: <a href="https://stackoverflow.com/questions/5493691/how-can-i-find-max-with-relational-algebra">How can I find MAX with relational algebra?</a> There is also good explanation of this concept in another answer here <a href="https://stackoverflow.com/questions/4952451/aggregate-relational-algebra-maximum">Aggregate Relational Algebra (Maximum)</a>

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.
