Cartesian Products
Last updated
Last updated
If two tables in a join query have no join condition, then Oracle Database returns their Cartesian product. Oracle combines each row of one table with each row of the other. ()
Oracle and Snowflake are also compatible with the ANSI Cross Join syntax that has the same behavior of a cartesian product.
No special transformation is performed for this kind of Join since Snowflake supports the same syntax.
The result of the query will have the same content in both database engines but the order might be different if no Order By clause is defined in the query.
