[Bug]: result.rowcount returns -1 after insert or update

[pavel-v-sobolev]

What happened?

I have a code which runs sql alchemy insert statement.
result = conn.execute(insert_stmt)
result.rowcount value is -1 instead of actual row count being inserted.

The same problem I observe for update and delete statements. All return -1 row count.
