It seems that something wrong with my system (I can't reproduce it using `docker run --rm -it node:8.5.0 bash`).

It happens on ``` $ lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 9.4 (stretch) Release: 9.4 Codename: stretch $ node --version v9.8.0 ``` and...

No, I use Debian on my laptop and Ubuntun on VPS.

Yes, the following also gets error: ```$ node -e " const node_pty = require('node-pty'); const pty = node_pty.spawn('bash'); pty.on('error', error => console.error(error)); setTimeout(function () { pty.write('exit\r\n'); }, 1000); " {...

Hi, Did you tried `$db->table()->where('column_name IS NOT NULL')`?

How then you distinct when column **contains string** `"IS NOT NULL"` and column **literally** `IS NOT NULL`?

Just a quick thought: `$db->table()->where($col, new IsNotNull())`. Then at the place `where` is implemented check its second argument for `instanceof IsNotNull`.

Right from the [docs](http://www.notorm.com/#api). ) > `$table->where("NOT field", array("x", "y"))` > Translated to NOT field IN ('x', 'y') (with automatic escaping)
