query for columns that are not null

[brachetti]

What would be a good way to query for a column that IS NOT NULL?
From reading the code I can see no way to do that.

While waiting for an answer I will prepare a PR how I would do it.

Cheers! :-)

Hi,

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

[brachetti]

That actually seems to work, judging from the tests. I'm not entirely sure, why, though ...

Since the code I have to maintain works very extensively with arrays, I would like to explicitly add where("column", "is not null") ... what do you think?

[vbarbarosh]

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

[brachetti]

That's a good point you make there. Intuitively I would answer that with $table->where($col, "'IS NOT NULL'"); but it's not really ideal considering backwards compatibility ... do you have a suggestion using the array syntax?

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

Hi,

This might work:

$db->table()->where("NOT $column", null);

Right from the docs. )

$table->where("NOT field", array("x", "y"))
Translated to NOT field IN ('x', 'y') (with automatic escaping)

So I guess it would be better to remove the new code in Result.php and just add more tests.
I also think that the documentation could be enhanced in that regard. Is there a repository where I could do that, which I missed?
