Hi Paul,

1) ODBC itself wouldn't "require" uppercasing column labels...and the manual
pages I've looked at don't say either...seems to me that some databases that
could be queried with ODBC are case sensitive when it comes to things like
column names (although SQL 7/2000 are case insensitive). I would say we
should pass back to the calling program whatever the database has sent to
us. That would seem like commonsense.

2) You're right that's a bug. It should return the truncated length, if
truncation has happened.
the buffer passed to sqldescribecol needs to be sufficient to hold the
column name + the null terminator.
