title: MySQL Error: #1452 - Cannot add or update a child row: a foreign key constraint fails
body: <p><img src="https://i.stack.imgur.com/RnOCd.png" alt="enter image description here"></p>
  
  <p>I am able to successfully insert a row in the <strong>business</strong> table but not the <strong>business_contact</strong> table. Whenever I try to insert a row in the <strong>business_contact</strong> table I get the following error:</p>
  
  <p><strong><em>#1452 - Cannot add or update a child row: a foreign key constraint fails</em></strong> </p>
  
  <p>Although the row that I'm attempting to insert into the <strong>business_contact</strong> table has a <em>BusinessID</em> that already exists in the <strong>business</strong> table.</p>
  
  <p><strong>business_contact</strong> failed insert statement</p>
  
  <pre><code>INSERT INTO business_contact(BusinessID, BusinessContactTypeID, BusinessContactData) VALUES (1, 1, '0097336031000');
  </code></pre>
