The following method may be used to avoid Cartesian products when you create a join.
- Usually you should have at least
t-1 join conditions for a join between
t tables.
- If there are multi-column primary keys on a referenced table, there should be as many join conditions between the child table and the referenced table as there are columns in the primary key of the referenced table.
- Turn on the
Prohibit Cartesian Products option.
