title: SQL Relationship Error
body: <p>I have a database and for the sake of simplicity, lets say it has two tables. One is Employee and the other is EmployeeType. In the Database diagram i am trying to build a relationship of the two tables but it gives me the following error....</p>
  
  <pre><code>'EmployeeType (HumanResources)' table saved successfully
  'Employee (HumanResources)' table
  - Unable to create relationship 'FK_Employee_EmployeeType'.  
  The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "FK_Employee_EmployeeType". The conflict occurred in database "TheDB", table "HumanResources.EmployeeType", column 'iID'.
  </code></pre>
