Assuming that "size" means "different number of columns", then appending is
not valid, because it would change the structure of the table, and with ODBC
we are in the relational database world. In that case, you should assemble
your data frame with all possible columns and leave the fields empty.
If size means "different number of rows", where append DOES make sense,
rbind is useful.
