I am sorry to say you're wrong about that. I am a 41 year old
webmaster who has some knowledge and experience of Oarcle Queries.
I've been struggling with the problem I stated for the last two
weeks... clearly I'm no crack at Oracle. So, I made the effort more
than twice... And I did state the version number; 'We use Oracle 9.'
but I guess that's not specific enough?
I am sorry that it looked that way though, but the problem I describes is a tuned-down version of the real problem I have here. So be carefull with your assumptions... ;-)
And David, thank you for the effort.
