Vantage does not copy statistics if an OLAP function is specified in the subquery as the examples in this set demonstrate.
Example1
In this example, Vantage does not copy statistics because of the OLAP RANK function in the subquery.
CREATE TABLE t3 (c1, c2, c3) AS (SELECT x, RANK(y), z FROM test QUALIFY RANK(X)> 1) WITH DATA AND STATISTICS;
Example2
In this example, Vantage does not copy statistics because of the partial data returned by the SAMPLE operator.
CREATE TABLE t3 (c1, c2, c3) AS (SELECT x, y, z FROM test SAMPLE 4) WITH DATA AND STATISTICS;
