This is where we differ :) I don't believe MySQL will return an entire
longs worth of data (typically 4 bytes) if the value is simply 1. By
return I mean across the network, etc. But maybe that is blind faith
in the skills of MySQLs developers? ;)

Sure. But in the example given this wasn't the use of the query - they
were checking to see if the user existed so they could INSERT a new
one.

I dunno.. I've seen shit code on every single system I've ever come
across :)
Best regards,
