About CROSS Join Operations
NuoDB does not support CROSS Joins, per se. However, NuoDB does support the joining of two sets of tables. The result set of this type of join can be similar to a CROSS join. This join would contain all rows in the first table that meet the WHERE clause criteria, if one is provided, joined to all rows in the second table that meet the WHERE clause criteria, if one is provided. There is no join-predicate defined, therefore rows do not have to contain matching values. Without the need to match row values, this result set can become very large, depending on the number of rows in each one of the tables. For example, if table1 has 10 rows and table2 has 5 rows and they are combined to produce a Cartesian product result set of rows, the total number of rows resulting would be 10 x 5 or 50 rows.
Using the tables created at About Join Operations Supported by NuoDB, we can see what it would look like if every player in the PLAYERS table, regardless of their team, were joined with every team in the TEAMS table using this type of join.
