title: Show constraints on tables command
body: <p>I have tables that I've tried setting PK FK relationships on but I want to verify this. How can I show the PK/FK restraints? I saw <a href="http://dev.mysql.com/doc/refman/5.5/en/table-constraints-table.html" rel="noreferrer">this</a> manual page, but it does not show examples and my google search was fruitless also. My database is <code>credentialing1</code> and my constrained tables are <code>practices</code> and <code>cred_insurances</code>.</p>
