    <p>That's on the right track, but you're missing a couple important points:</p> <ol> <li>You aren't closing your connection correctly. If your sql statement throws an exception, you'll never reach the .Close() call. Depending on your database type and how it's configured, this can result in maxing out your db server's available connections and effectively locking yourself out of your own database.</li> <li>Where did the "1" come from in "idPeople=1"? There is a right way and a wrong way to build queries containing argument data like that "1". Make sure you do it the right way.</li> <li>"SELECT *" is considered bad form... much better to specify the column list.</li> </ol> <p>Here is an example that solves all these issues:</p> <pre><code>//often this will loaded from a config file string connString = "Server=localhost;database=super;uid=root;password=root"; string sql = "SELECT &lt;column list&gt; FROM people WHERE idPeople= @idPeople"; using (var cn = new MySqlConnection(connString)) uinsg (var cmd = new MySqlCommand(sql, cn)) { cmd.Parameters.Add("@idPeople", MySqlDbType.Int32).Value = 1; conn.Open(); //get data } </code></pre> <p>You'll see some people tell you to use an ORM, like NHibernate, linq-to-sql, Entity Framework, etc. I tend to think there's still a place for hand-coded and tuned sql, and I don't pay much attention to them. A light-weight data access framework like <a href="https://code.google.com/p/dapper-dot-net/" rel="nofollow noreferrer">Dapper</a> can be helpful, though. These can abstract away much of the boilerplate code not only from what I just wrote, but also the business and transport object layers, and still let you write whatever sql you need.</p>

Querying!

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.
