Question

This is my query:

SELECT *, `online_since`-NOW() as 'uptime' FROM map_eline_dots

I want it to select all columns in map_eline_dots plus an extra field “uptime” that contains the result of

online_since - NOW()

However I’m getting the same result now as I did from

SELECT * FROM map_eline_dots

What am I doing wrong? Do I HAVE to select every single one of the other 30 columns manually?

Answer 1

Like this:

SELECT map_eline_dots.*, online_since - NOW() as uptime FROM map_eline_dots

Or like this.

SELECT m.*, online_since - NOW() as uptime FROM map_eline_dots AS m

You have to qualify the asterisk, if you select more than just the asterisk. (I removed backticks and quotes to increase readability)
