Question

Is it possible to execute a select query where the id column is within the last 50 rows?
So like WHERE id > total id – 50.

Something like that?
Not sure of the syntax!
Cheers

You can use the above if you just want the last 50 items, and it’s probably the cleanest and best way. But if you really care about the ID for some reason, you can use the MAX function:

SELECT * 
    FROM table 
    WHERE id > (SELECT MAX( id ) FROM table) - 50 
          AND whatImLookingFor = 'Somesuch'

This of course isn’t terribly efficient and is somewhat unweidly, but will do exactly what you were asking about.
