Subject Foreign Keys in Torque
Date Wed, 10 Dec 2003 15:50:33 GMT
In the database.dtd I've found that onDelete and onUpdate can have the
values (cascade|setnull|restrict|none)
 
<!ELEMENT foreign-key (reference+)>
<!ATTLIST foreign-key
  foreignTable CDATA #REQUIRED
  name CDATA #IMPLIED
  onUpdate (cascade|setnull|restrict|none) "none"
  onDelete (cascade|setnull|restrict|none) "none"
>
 
Can somebody explain which the difference between them is please?
 
Thank you, Julio Cesar De Salvo
