You can't stretch a FK constraint across databases. You're going to have to use a trigger.

The tables are organized in different databases, because the main database "crm" has the definitions tables that are commons for the others, for example, the table suppliers of "crm" database is common for the database "inventory_company_a", "inventory_company_b", "accounting_company_a", "accounting_company_b", ......, so, I need to keep the integrity, I can´t delete a supplier involved for example, in "orders" in "inventory_company_a" and in "accountig_company_b".
