drop dataverse test1 if exists;
create dataverse test1;
use test1;
create type DocumentType as open { };
create type MetaType as open { id:string };
create dataset customer(DocumentType) with meta(MetaType) primary key meta().id;
create dataset orders(DocumentType) with meta(MetaType) primary key meta().id;
create dataset lineitem(DocumentType) with meta(MetaType) primary key meta().id;
select count(*)
from orders o, lineitem l, customer c
where tobigint(l.l_orderkey) = o.o_orderkey
and o.o_custkey + l.l_orderkey = c.c_custkey + l.l_orderkey;
