Can you see the problem?
Didn't think so. I'll clue you in: the last one in that list has one distinct difference with the first four. Look around you. Have you found what we're looking for?
That is correct. The answer is: the semicolon. A lightweight, generally meaningless way to end a statement in most common languages. Arguably useless to users, arguably beneficial to parsers, and the cause of almost half an hour of continuous head-scratching by both programmer and DBA. How so?
C:\Temp>mysql -C -usomeuser -phispassword thedatabase;
ERROR 1044 (42000): Access denied for user 'someuser'@'%' to database 'thedatabase;'
I'll let you draw your own conclusions.
