title: deletion in multiple tables with foreign keys
body: <p>I have 3 tables in my sql database: </p>
  
  <pre><code>assignresources
  tasks 
  project
  </code></pre>
  
  <p>the <code>project</code> table has columns </p>
  
  <pre><code>ID(pk),
  Guid,
  name, 
  startdate, 
  enddate
  </code></pre>
  
  <p>the other 2 tables have the <code>Guid</code> columns with some other names. How can i delete related  rows in all the tables(with matching <code>Guid</code> values) depending on row deletion in <code>Project</code> table Via <code>ID</code> column?</p>
