I think col != value is the most common. I'm wary of more convoluted conditions like not(col = value) as when reading code it makes you wonder if the original author thought it did some extra magic. On Thu, 5 Nov 2020 at 14:35, Fridolin SOMERS <fridolin.somers@biblibre.com> wrote:
Hi,

This query does not return rows where login_attempts IS NULL. It will return accounts where login_attempts = 0
I only recently understood the behavior or NULL values in SQL queries for NOT IN and !=.
Should be advice this in coding guide lines ? Is there a syntax better than another : col!=value / not(col=value) ?
