title: Error 3022 Cannot add a duplicate value because of a key constrain
body: <p>I am trying to insert a value into a table and i am getting an error 3022(It says that there might be a problem with a relation, a key or index). I have not created the table myself but i found out the specific column that triggers the error. I have checked that its not a key, index and there is not a relation to that table that depends on that specific column.
  Is there anything i can do to avoid that error?</p>
  
  <p>Thanks in advance. </p>
