Pivot table filter list not updating

Block sampling is possible only during full table scans or index fast full scans.If a more efficient execution path exists, then Oracle Database does not perform block sampling.It takes less than a minute and it is a huge help to other students, and to me too. You can then reference the subquery block multiple places in the query by specifying the query name.

Oracle Database returns all committed versions of the rows that existed between two SCNs or between two timestamp values.A query that selects rows from two or more tables, views, or materialized views is a join.You can use the schema qualifier to select from a table, view, or materialized view in a schema other than your own.When used in the subquery of a DML statement, you can specify this clause in a subquery in the can be a subquery, a column, a function, or a collection constructor.Regardless of its form, it must return a collection value—that is, a value whose type is nested table or varray.The rows returned include deleted and subsequently reinserted versions of the rows.
