  • Articolo

This tab in the Referential Integrity (RI) builder specifies rules to apply when a new record is inserted or an existing record is updated in the child table.

  • Restrict
    Prevents you from adding records in the child table for which there are no matching records in the parent table. If you select Restrict Insert for a relationship, an attempt to add records in the child table generates an error if there is no matching parent record.
