I'm currently interfacing with an Oracle db using sqlalchemy without
any sessions or mappings. Selects and inserts work great, but I'd
like to be able to update a row without having to delete and reinsert
it.
# remove the id
table.delete(table.c.id == row['id']).execute()
# add it back with new value
row['name'] = 'now frank'
self.conn.execute(table.insert(), row)
I realize there there's an update function in table, but I'm at a loss
as to how to use the syntax for it. I'm just changing one or two
non-primary-key values. All the examples I see use the ORM mappings
with sessions, or use the update to change every field in a column.
