You specified both COLUMN and TABLE privileges with a POSITION
  or AFTER clause

  Explanation:  You specified both COLUMN and TABLE privileges in
  a GRANT or REVOKE statement with a POSITION or AFTER clause.
  Unless the ACLs are identical on both the column and the table,
  this could produce misleading results.

  User Action:  Specify the column and table privileges in
  separate GRANT or REVOKE statements.
