Question

by default I have one column in MySQL table to be NULL.

I want to select some rows but only if the field value in that column is not NULL.

what is the correct way of typing it?

$query = "SELECT *
        FROM names
        WHERE id = 1
        AND name != NULL";

Is this correct?

You should use:

$query = "SELECT *
        FROM names
        WHERE id = 1
        AND name IS NOT NULL";

You must use IS NULL or IS NOT NULL when working with NULL values
