MySQL ALTER TABLE hangs
<p>I know this question was asked several times already but my problem is happening with a table I've just created. It has only 10 columns and only 1 row in it. </p>

<p>So unlike the usual hanging problem this is not the case of a large table with a lot of data. And yet it hangs.</p>

<p>This is the SQL I'm running: </p>

<pre><code>ALTER TABLE `db`.`Search` 
ADD COLUMN `useremail` VARCHAR(256) NOT NULL COMMENT '' AFTER `id`;
</code></pre>

<p>Simple enough and yet it hangs (50 minutes and counting.) I tried quitting <code>Workbench</code> and <code>Eclipse</code> and deleting all <code>java</code> processes and the one <code>mysqld</code> process. But no luck. </p>

<p>I'm running on a <code>Mac OSX El Capitain</code>. How do I add this column to my table? </p>
