following table.

That's why doctrine/migrations should not use `executeUpdate`, because
results are not read. So the user can end with the following errors

```
  SQLSTATE[HY000]: General error: 2014 Cannot execute queries while
other unbuffered queries are active.  Consider using
PDOStatement::fetchAll().  Alternatively, if your code is only ever
going to run against mysql, you may enable query buffering by
setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute.
```

More over, `executeUpdate` is deprecated
