    Description

      Consider this SQL:
      SELECT SUM(L_EXTENDEDPRICE * (1 - L_DISCOUNT)) AS REVENUE FROM LINEITEM, PART WHERE ( P_PARTKEY = L_PARTKEY AND P_BRAND = 'Brand#41' AND P_CONTAINER IN ( 'SM CASE', 'SM BOX', 'SM PACK', 'SM PKG') AND L_QUANTITY >= 3 AND L_QUANTITY <= 3 + 1 AND P_SIZE BETWEEN 1 AND 5 AND L_SHIPMODE IN ('AIR', 'AIR REG') AND L_SHIPINSTRUCT = 'DELIVER IN PERSON' ) OR ( P_PARTKEY = L_PARTKEY AND P_BRAND = 'Brand#33' AND P_CONTAINER IN ( 'MED BAG', 'MED BOX', 'MED PKG', 'MED PACK') AND L_QUANTITY >= 14 AND L_QUANTITY <= 14 + 1 AND P_SIZE BETWEEN 1 AND 10 AND L_SHIPMODE IN ('AIR', 'AIR REG') AND L_SHIPINSTRUCT = 'DELIVER IN PERSON' ) OR ( P_PARTKEY = L_PARTKEY AND P_BRAND = 'Brand#45' AND P_CONTAINER IN ( 'LG CASE', 'LG BOX', 'LG PACK', 'LG PKG') AND L_QUANTITY >= 25 AND L_QUANTITY <= 25 + 1 AND P_SIZE BETWEEN 1 AND 15 AND L_SHIPMODE IN ('AIR', 'AIR REG') AND L_SHIPINSTRUCT = 'DELIVER IN PERSON' );

      For mode 0 (vtable mode) This will result in:
      ERROR 1815 (HY000): Internal error: IDB-1000: 'lineitem' and 'part' are not joined.

      For mode 2 (autoswitch)
      The correct answer is given.

      From this, one could assume that the correct answer could also be obtained in mode 1, but one would be mistaken. Instead you get:
      ERROR 1815 (HY000): Internal error: IDB-1000: 'lineitem' and 'part' are not joined.
