I'm not sure I understand this, and the example is using dbSendStatement()
in a way that differs slightly from the documentation I see (which covers INSERT
/UPDATE
/DELETE
but not CREATE
statements).
Do you have an example of a backend that implements this as intended? It's also a bit hard to search for.
