RethinkDB multiple queries in a single request

Question

I'm trying to execute several RQL commands in a single request to server, without much success I may add. I have tried r.union, but it only works with sequences. What I really want:

[r.db(..).table(..).get(id1).delete(),
 r.db(..).table(..).get(id2).delete(),
 r.db(..).table(..).insert(...)].run_all_at_once

Is there any way to do this?

Thanks!

Answer 1

You can do

r.expr( [r.db(...).table(...).get(id1).delete(), 
r.db(...).table(...).get(id1).delete(), 
r.db(...).table(...).insert(...) ] ).run(conn)

Note that the method delete doesn't get an argument.

Answer 2

You can also use do

r.do(
  r.table('test').insert({value1: "Hey"}),
  r.table('test').insert({value2: "Ho"})
).run(conn);

• The queries are evaluated from last to first
• The response will be the last query's result
