I have decimail fields in my database, and if they are empty(not filled in form) a have error: "Incorrect decimal value" instead behavior of int fields which are covered by

if (stristr($tableColumns[$k], 'int') !== false && $v === '') {
                continue;
            }

in mysql drivers.

If I add under this next code:

if (stristr($tableColumns[$k], 'decimal') !== false && $v === '') {
                continue;javascript:
            }

the behaviour works as expected and item is saved without error
