Regarding Oracle join and ANSI join syntax:
* B. The Oracle join syntax supports the creation of a Cartesian product of two tables. This is true.
In Oracle, if you list tables in the FROM clause without a join condition, it creates a Cartesian product.
* C. The SQL:1999 compliant ANSI join syntax supports natural joins. This is true. ANSI syntax supports natural joins, which join tables based on columns with the same names in the joined tables.
* F. The SQL:1999 compliant ANSI join syntax supports the creation of a Cartesian product of two tables. This is true. The ANSI standard allows for Cartesian products when tables are listed in the FROM clause without a join condition.
Options A, D, E, and G are incorrect:
* A is incorrect because the Oracle join syntax supports all types of joins, including right outer joins.
* D is incorrect because Oracle's proprietary join syntax does not use the term "natural join."
* E is incorrect because there is no inherent performance difference between Oracle join syntax and ANSI join syntax; performance depends on how the query is written and how the database optimizer handles it.
* G is incorrect for the same reason as E.
