Prepared Statement with collection in IN clause in Datastax Cassandra CQL driver

Question

I am trying to run the following query

SELECT edge_id, b_id FROM booking_by_edge WHERE edge_id IN ?

I bind Java list of Long's as a parameter and I get an exception

SyntaxError: line 0:-1 mismatched input '<EOF>' expecting ')' (ResultSetFuture.java:242)

If I try to use (?) it expects single Long item to be bound, but I need a collection

Is there an error in my syntax?

Answer 1

Got response on Datastax bugzilla, it is currently not supported, but planned

https://issues.apache.org/jira/browse/CASSANDRA-4210

Update: Supported in Cassandra 2.0.1

Answer 2

Tested in Cassandra 2.1.3, the following code snippet works:

PreparedStatement prepared = session.prepare("SELECT edge_id, b_id FROM booking_by_edge WHERE edge_id IN ?;");
List<Long> edgeIds = Arrays.asList(1L, 2L, 3L);
session.execute(prepared.bind(edgeIds));

Answer 3

It's a bit hard to find in the documentation but it is described in the tuples section of the manual.

If you want to use named parameters you should use the setList() method.

BoundStatement bs = session.prepare("select col from table where col in :values").bind();
bs.setList("values", Arrays.asList(v1, v2, v3));
