Hi I have 2 tables Document and Project.

DocumentID is an FK in the Project table.

Using sql How can I delete Document Records in the Document table,
and also remove their corresponding records in the Project table.

Answer 1

delete 
  from projects 
 where documentsFK = (
                      select documentFK 
                        from documents 
                       where documentsFK > 125
                     );

delete 
  from documents 
 where documentsFK > 125;

EDIT

delete 
  from projects 
 where documentsFK in (
                       select documentFK 
                         from documents 
                        where documentsFK > 125
                      );

delete 
  from documents 
 where documentsFK > 125;
