Hello !
I've got 2 databases. In the first i've got users described in a table
(name, adress ..).
In the second, i've got a table with products informations (id, price, owner
...).
I must create a trigger in the second table on insert that verify that the
product's owner exists in the first database.
Anyone has an idea on how to do it ?
(i can't merge the two databases)
have a nice day !
