You are new at this, aren't you? First thing you need to do is to let us
see exactly what we need to deal with. Please respond with the results of
the following two commands
SHOW CREATE TABLE Employees\G
SHOW CREATE TABLE ProblemReports\G
We (the list members) will be able to help straighten you out from there
(there are lots of things we need to talk about but I think that we should
get you working first, ok?)
Always CC the list (or hit the REPLY TO ALL button or whatever you have in
your email client). That way everyone on the list stays informed of the
progress of this issue.
