I fully endorse the idea that people should read the manuals and they
will learn a lot. However, we should remember that sometimes these
people are "newbies" as "Me" claims to be. How is a total newbie
expected to know that the way to find out the primary key of a table is
not via the DESC command (which shows SOME information about a table),
but by selecting from a set of views documented in the Oracle Database
Reference manual (not in the SQL reference manual for example?)
Sometimes people need a gentle nudge in the right direction!
