> json data
> {code:java}
> Query : SELECT customer.c_custkey,customer.c_acctbal,orders.o_orderkey,
> orders.o_totalprice,orders.o_orderdate FROM customer, LATERAL
> (SELECT O.ord.o_orderkey as o_orderkey, O.ord.o_totalprice as
> o_totalprice,O.ord.o_orderdate as o_orderdate FROM UNNEST(customer.c_orders)
> O(ord) WHERE year(O.ord.o_orderdate) <> 1998)orders;
> {code}
> The data is sf001 complex data in multi json format partitioned based on the
> year of the o_orderdata column.
> The last json file(for year 1998) has 2 schema changes for c_acctbal and
> o_shippriority .
