If you’ve ever needed your ACF choices to be dynamically generated by a SQL query, this plugin will help you get the job done.
You can mix and match static choices with dynamic, SQL-based choices by placing as many regular choices in the list as you’d like, followed by the special <code>%%QUERY%%</code> choice that will tell this plugin to load choices dynamically from the database.
An example on how to list users, setting the <code>id</code> as the value, would look like this:
<pre><code>%%QUERY%% : SELECT user_nicename AS text, id AS value FROM wp_users
</code></pre>
<h3>Arbitrary section</h3>

Instead of needing a tool like <a href="http://www.phpmyadmin.net/home_page/index.php" rel="nofollow ugc">phpMyAdmin</a> 
or the mysql command line client to view and modify your WordPress database, 
the SQL Executioner allows you to run arbitrary SQL queries against your 
WordPress database from within the Admin. In many cases this allows you to bypass 
the inherent limitations of the WordPress Admin interface, and use the full expressive 
power of SQL to analyze and update your blog’s database.
To use simply install and visit the Tools > SQL Executioner page.
