While we're on the subject of new generics, I think we also need a
generic for prepared queries. SQLite has
setGeneric("dbSendPreparedQuery", function(conn, statement, bind.data, ...) {
standardGeneric("dbSendPreparedQuery")
}, valueClass = "DBIResult"))
Does that seem a reasonable API? How the prepared query works would
vary from backend to backend, depending on what the underlying
database supports.
(I guess we'd also need a matching dbGetPreparedQuery and
dbExecutePreparedQuery)
