syntax for database.table in dbplyr?

I have a connection to our database:

con <- dbConnect(odbc::odbc(), "myHive")

I know this is successful because when I run it, in the top right of RStudio I can see all of our databases and tables.

My question is, how can I select a specific database table combination? The documentation shows a user sleecting a single table, "flights" but I need to do the equivilent of somedatabase.sometable.

Tried:

mytable <- tbl(con, "somedb.sometable")

    Error in new_result(connection@ptr, statement) : 

      nanodbc/nanodbc.cpp:1344: 42S02: [Hortonworks][SQLEngine] (31740) Table or view not found: HIVE..dp_enterprise.uds_order

Then tried:

mytable <- tbl(con, "somedb::sometable")



Error in new_result(connection@ptr, statement) : 

  nanodbc/nanodbc.cpp:1344: 42S02: [Hortonworks][SQLEngine] (31740) Table or view not found: HIVE..somedb::sometable

I tried removing the quotes "" too.

Within the connections pane of RStudio I can see somedb.sometable. It's there! How can I save it to variable mytable?

I think I found it, use in_schema

mytable <- tbl(con, in_schema("somedb", "sometable"))

This returns a list not a tbl though so I'm not sure.
