      Description

      Certain types of query will result in the following error:
      ERROR 1815 (HY000) at line 6: Internal error: IDB-1003: Circular joins are not supported.

      This happens if a given table is joined more than once. This is a common pattern and can be generated by bi tools including microstrategy.

      dbt3 query 5 is one such example that should be supported:

      execute the query #5
       
      select
      n_name,
      sum(l_extendedprice * (1 - l_discount)) as revenue
      from
      customer,
      orders,
      lineitem,
      supplier,
      nation,
      region
      where
      c_custkey = o_custkey
      and l_orderkey = o_orderkey
      and l_suppkey = s_suppkey
      and c_nationkey = s_nationkey
      and s_nationkey = n_nationkey
      and n_regionkey = r_regionkey
      and r_name = 'AMERICA'
      and o_orderdate >= '1993-01-01'
      and o_orderdate < date_add( '1993-01-01' , interval 1 year)
      group by
      n_name
      order by
      revenue desc;
