I would like to make one of the columns in a data frame the primary key.
Using RODBC it seems that it always specifies a numerical index 'rownames'
and you only have a choice of renaming that variable (rownames = "char") and
setting it as the primary key (or not). I would like to not have this
variable in the db table and just use another variable as the primary key
(something like 'patient name' or 'id'). Is this possible?
