Notable changes since 0.7.0:
- SQL() now strips the names from the output if the names argument is
unset.
- The dbReadTable(), dbWriteTable(), dbExistsTable(), dbRemoveTable(),
and dbListFields() generics now specialize over the first two
arguments to support implementations with the Id S4 class as type
for the second argument. Some packages may need to update their
documentation to satisfy R CMD check again.
- Schema support: Export Id(), new generics dbListObjects() and
dbUnquoteIdentifier(), methods for Id that call dbQuoteIdentifier()
and then forward.
- New dbQuoteLiteral() generic. The default implementation uses
switchpatch to avoid dispatch ambiguities, and forwards to
dbQuoteString() for character vectors. Backends may override methods
that also dispatch on the second argument, but in this case also an
override for the "SQL" class is necessary.
